本申请涉及网络技术领域，特别涉及一种网络管理方法、装置及系统、存储介质。The present application relates to the field of network technology, and in particular to a network management method, device and system, and storage medium.
背景技术Background technique
软件定义广域网(software defined wide area network，SDWAN)通常包括控制器和多个网络节点，该多个网络节点可以包括总部(hub)节点和分支(spoke)节点，总部节点用于管理分支节点，控制器用于管理总部节点和分支节点。SDWAN中的该多个网络节点之间可以基于多协议标签交换(multi-protocol label switching，MPLS)技术、因特网(internet)技术或长期演进(long term evolution，LTE)技术相互通信，并基于动态智能虚拟专用网络(dynamic smart virtual private network，DSVPN)技术或智能虚拟专用网络(automatic virtual private network，Auto VPN)技术构建虚拟业务网络。A software defined wide area network (SDWAN) generally includes a controller and multiple network nodes, which may include a hub node and a spoke node, the hub node is used to manage the spoke node, and the controller is used to manage the hub node and the spoke node. The multiple network nodes in the SDWAN can communicate with each other based on multi-protocol label switching (MPLS) technology, Internet technology or long term evolution (LTE) technology, and build a virtual business network based on dynamic smart virtual private network (DSVPN) technology or automatic virtual private network (Auto VPN) technology.
为了降低总部节点的性能压力，基于Auto VPN技术的SDWAN中增加了路由反射器(route reflector，RR)，将总部节点的部分功能转移到RR上，由RR对网络节点(例如包括总部节点和分支节点)进行管理，例如，由RR转发不同的网络节点的路由信息。目前，在基于Auto VPN技术的SDWAN中，当网络节点较多时，为了降低RR的性能压力，通常会对该SDWAN分区域管理。也即是，将SDWAN划分为多个区域，每个区域中包括一个RR和至少两个网络节点，不同区域中的RR相互通信，每个区域中的RR与网络节点相互通信，每个区域中的不同网络节点在该区域中的RR管理下相互通信。In order to reduce the performance pressure of the headquarters node, a route reflector (RR) is added to the SDWAN based on Auto VPN technology, and part of the functions of the headquarters node are transferred to the RR, which manages the network nodes (such as the headquarters node and branch nodes). For example, the RR forwards the routing information of different network nodes. At present, in the SDWAN based on Auto VPN technology, when there are many network nodes, in order to reduce the performance pressure of the RR, the SDWAN is usually managed in different regions. That is, the SDWAN is divided into multiple regions, each region includes an RR and at least two network nodes, the RRs in different regions communicate with each other, the RRs in each region communicate with the network nodes, and the different network nodes in each region communicate with each other under the management of the RR in the region.
但是，对SDWAN分区域管理的方案中，不同区域中的网络节点若需要相互访问，需要该不同区域中的RR相互交互为该不同区域中的网络节点配置路由信息，并反射该路由信息，因此RR的性能压力较大。However, in the SDWAN regional management solution, if network nodes in different areas need to access each other, the RRs in different areas need to interact with each other to configure routing information for the network nodes in different areas and reflect the routing information, so the performance pressure of RR is relatively high.

传统企业通常将应用部署在总部的数据中心，通过租用MPLS专线访问数据中心的应用。随着云计算的引入，越来越多的应用虚化，并迁移至云端，使得分支节点的出口流量增加，传统的MPLS专线费用昂贵，部署成本较高。并且，由于国家和区域的不同，应用的接入方式也大相径庭，需要企业同时支持Internet、LTE或者MPLS等不同的部署方式接入，导致网络和业务部署复杂，网络维护以及网络管理困难。Traditional enterprises usually deploy applications in the data center of the headquarters and access the applications in the data center by renting MPLS dedicated lines. With the introduction of cloud computing, more and more applications are virtualized and migrated to the cloud, which increases the export traffic of branch nodes. Traditional MPLS dedicated lines are expensive and the deployment cost is high. In addition, due to differences in countries and regions, the access methods of applications are also very different. Enterprises need to support different deployment methods such as Internet, LTE or MPLS at the same time, which makes network and service deployment complicated, and network maintenance and network management difficult.

It includes AC and multiple network nodes. AC manages the multiple network nodes in a unified manner, realizes flexible deployment of services on demand, reduces network deployment costs, and reduces equipment management and maintenance expenses. Among them, AC is a management controller launched based on the software defined network (SDN) architecture, and the multiple network nodes may include headquarters nodes and branch nodes. The headquarters node is used to manage the branch nodes, and the controller is used to manage the headquarters nodes and the branch nodes. Each of the multiple network nodes may be a customer premises equipment (CPE), a universal customer premises equipment (uCPE) or a virtual customer premises equipment (vCPE). Multiple network nodes can communicate with each other based on MPLS, Internet or LTE, and a virtual service network can be built based on DSVPN technology or Auto VPN technology.
其中，DSVPN技术是一种在总部节点和分支节点建立组网方式(通常也称为hub-spoke组网方式)下，在公网地址动态变化的分支节点之间建立VPN隧道的VPN技术，通过DSVPN技术，不同分支节点之间，以及分支节点与总部节点之间均可以建立DSVPN隧道(基于DSVPN技术建立的VPN隧道可以称为DSVPN隧道)，每个分支节点可以通过总部节点获取其他分支节点的公网地址，并基于获取的该其他分支节点的公网地址与该其他分支节点建立DSVPN隧道，使得不同分支节点可以通过DSVPN隧道直接互访，减少数据传输时延。Among them, DSVPN technology is a VPN technology that establishes VPN tunnels between branch nodes whose public network addresses dynamically change under a networking mode established between a headquarters node and a branch node (also commonly referred to as a hub-spoke networking mode). Through DSVPN technology, DSVPN tunnels can be established between different branch nodes, as well as between branch nodes and headquarters nodes (VPN tunnels established based on DSVPN technology can be called DSVPN tunnels). Each branch node can obtain the public network addresses of other branch nodes through the headquarters node, and establish DSVPN tunnels with the other branch nodes based on the obtained public network addresses of the other branch nodes, so that different branch nodes can directly visit each other through the DSVPN tunnel, thereby reducing data transmission delays.
其中，Auto VPN技术是一种用于虚拟业务网络与底层传输网络分离，以及，业务网络路由与传输网络路由分离的VPN技术。在Auto VPN技术中，通过扩展边界网关协议(border gateway protocol，BGP)协议，使不同网络节点的底层传输网络互通，从而实现业务网络的数据流量转发。基于Auto VPN技术的SDWAN中增加了RR，弱化了总部节点的角色，将总部节点的部分功能转移到RR上，由RR对网络节点(例如包括总部节点和分支节点)进行管理，例如，由RR反射网络节点的传输网络信息以及网络节点的路由信息。在基于Auto VPN技术的SDWAN中，数据流量是否需要由总部节点转发，可以由RR反射路由信息时，改变路由属性来实现。Among them, Auto VPN technology is a VPN technology used to separate virtual business networks from underlying transmission networks, and business network routing from transmission network routing. In Auto VPN technology, the underlying transmission networks of different network nodes are interconnected by extending the border gateway protocol (BGP) protocol, thereby realizing data traffic forwarding of the business network. RR is added to SDWAN based on Auto VPN technology, weakening the role of the headquarters node, transferring part of the functions of the headquarters node to RR, and RR manages network nodes (for example, including headquarters nodes and branch nodes), for example, RR reflects the transmission network information of network nodes and the routing information of network nodes. In SDWAN based on Auto VPN technology, whether data traffic needs to be forwarded by the headquarters node can be achieved by changing the routing attributes when RR reflects the routing information.
目前，在基于Auto VPN技术的SDWAN中，当网络节点较多时，为了降低RR的性能压力，通常会对该SDWAN分区域管理。但是，对SDWAN分区域管理的方案中，通常只能定义不同区域中的RR之间的组网方式，而无法定义不同区域中的网络节点之间的组网方式，导致SDWAN存在域间组网隔离(也即是不同区域的组网隔离)问题，并且分区域管理会导致SDWAN的组网对外复杂化，且不同区域中的网络节点若需要相互访问，需要该不同区域中的RR相互交互为该不同区域中的网络节点配置路由信息，并反射该路由信息，因此RR的性能压力较大，配置复杂。At present, in SDWAN based on Auto VPN technology, when there are many network nodes, in order to reduce the performance pressure of RR, the SDWAN is usually managed by different regions. However, in the solution of regional management of SDWAN, usually only the networking mode between RRs in different regions can be defined, but the networking mode between network nodes in different regions cannot be defined, which leads to the problem of inter-domain network isolation (that is, network isolation of different regions) in SDWAN, and regional management will make the networking of SDWAN complicated externally, and if network nodes in different regions need to access each other, RRs in different regions need to interact with each other to configure routing information for network nodes in different regions and reflect the routing information, so the performance pressure of RR is relatively large and the configuration is complicated.
鉴于此，本申请实施例提供了一种网络管理方法及装置、系统、存储介质，本申请实施例提供的技术方案中，引入RR组的概念，将SDWAN中分布式部署的多个RR视为RR组，RR组内的RR通过信息共享来反射不同网络节点的路由信息(也可以是其他信息，例如传输网络信息)，使不同网络节点实现路由互通，并相互访问。相比于分区域管理的方案，本申请实施例提供的技术方案不存在域间组网隔离问题，也不会导致SDWAN的组网对外复杂化，更不会增大性能压力，可以简化配置。本申请实施例的详细方案请参考下述实施例的描述。In view of this, the embodiments of the present application provide a network management method and device, system, and storage medium. In the technical solution provided by the embodiments of the present application, the concept of RR group is introduced, and multiple RRs deployed in a distributed manner in SDWAN are regarded as RR groups. The RRs in the RR group reflect the routing information of different network nodes (or other information, such as transmission network information) through information sharing, so that different network nodes can achieve routing intercommunication and access each other. Compared with the regional management solution, the technical solution provided by the embodiments of the present application does not have the problem of inter-domain network isolation, nor will it cause the external complication of SDWAN's networking, nor will it increase performance pressure, and can simplify the configuration. For the detailed solution of the embodiments of the present application, please refer to the description of the following embodiments.
本申请实施例提供的技术方案的实施环境可以是通信网络，该通信网络可以是基于VPN技术的SDWAN，例如，基于Auto VPN技术的SDWAN。该通信网络可以包括路由反射器组和多个网络节点，该路由反射器组包括多个路由反射器，该路由反射器组中的每个路由反射器与该路由反射器组中的至少一个路由反射器之间建立有传输通道。可选地，该路由反射器组中的每个路由反射器与该路由反射器组中的所有路由反射器之间建立有传输通道，每个路由反射器与该路由反射器组中的其他路由反射器之间的传输通道可以是直接传输通道和/或间接传输通道。可选地，该路由反射器组中的每个路由反射器与该路由反射器组中的所有路由反射器之间建立有直接传输通道。其中，直接传输通道可以是一段传输通道，间接传输通道可以由多段直接传输通道构成，建立直接传输通道的两个路由反射器通常可以直接传输信息，而不需要经过其他路由反射器，建立间接传输通道的两个路由反射器通常可以间接传输信息(也即是传输信息可以经过其他路由反射器)，容易理解，如果两个路由反射器之间既建立有直接传输通道，又建立有间接传输通道，则该两个路由反射器可以通过该直接传输通道直接传输信息，也可以通过该间接传输通道间接传输信息，并且通常情况下，该两个路由反射器通过该直接传输通道直接传输信息，本申请实施例对此不做限定。The implementation environment of the technical solution provided in the embodiment of the present application may be a communication network, and the communication network may be an SDWAN based on VPN technology, for example, an SDWAN based on Auto VPN technology. The communication network may include a route reflector group and a plurality of network nodes, the route reflector group includes a plurality of route reflectors, and a transmission channel is established between each route reflector in the route reflector group and at least one route reflector in the route reflector group. Optionally, a transmission channel is established between each route reflector in the route reflector group and all route reflectors in the route reflector group, and the transmission channel between each route reflector and other route reflectors in the route reflector group may be a direct transmission channel and/or an indirect transmission channel. Optionally, a direct transmission channel is established between each route reflector in the route reflector group and all route reflectors in the route reflector group. Among them, the direct transmission channel can be a transmission channel, and the indirect transmission channel can be composed of multiple direct transmission channels. The two route reflectors that establish a direct transmission channel can usually transmit information directly without passing through other route reflectors. The two route reflectors that establish an indirect transmission channel can usually transmit information indirectly (that is, the transmitted information can pass through other route reflectors). It is easy to understand that if both a direct transmission channel and an indirect transmission channel are established between two route reflectors, the two route reflectors can directly transmit information through the direct transmission channel, or can indirectly transmit information through the indirect transmission channel. In general, the two route reflectors directly transmit information through the direct transmission channel, and the embodiments of the present application are not limited to this.
可选地，该通信网络还可以包括控制器，该控制器用于管理该路由反射器组以及该多个网络节点，该路由反射器组也可以用于管理该多个网络节点，本申请实施例以路由反射器组管理该多个网络节点为例说明。Optionally, the communication network may further include a controller, which is used to manage the route reflector group and the multiple network nodes. The route reflector group may also be used to manage the multiple network nodes. The embodiment of the present application takes the route reflector group managing the multiple network nodes as an example.
示例地，请参考图1，其示出了本申请实施例所涉及的一种实施环境的示意图，该实施环境提供一种通信网络，该通信网络包括路由反射器组和多个网络节点，该路由反射器组包括路由反射器001～003(也即是路由反射器001、路由反射器002和路由反射器003)，该多个网络节点包括网络节点011～016(也即是网络节点011、网络节点012、网络节点013、网络节点014、网络节点015和网络节点016)。其中，路由反射器001～003中的每个路由反射器与该路由反射器组中的至少一个路由反射器之间建立有传输通道。可选地，路由反射器001～003中的每个路由反射器与该路由反射器组中的所有路由反射器之间建立有传输通道，每个路由反射器与该路由反射器组中的其他路由反射器之间的传输通道可以是直接传输通道和/或间接传输通道。例如，路由反射器001与路由反射器002之间建立有直接传输通道，且路由反射器001与路由反射器002之间建立有间接传输通道(该间接传输通道由路由反射器001与路由反射器003之间的直接传输通道，以及，路由反射器003与路由反射器002之间的直接传输通道构成)。又例如，路由反射器002与路由反射器003之间建立有直接传输通道，且路由反射器002与路由反射器003之间建立有间接传输通道(该间接传输通道由路由反射器002与路由反射器001之间的直接传输通道，以及，路由反射器001与路由反射器003之间的直接传输通道构成)。如图1所示，本申请实施例以路由反射器001～003之间彼此建立有直接传输通道为例进行说明。在本申请实施例中，该传输通道可以是VPN隧道，例如，Auto VPN隧道，该传输通道可以用于传输数据，因此该传输通道也可以称为数据通道。For example, please refer to FIG. 1, which shows a schematic diagram of an implementation environment involved in an embodiment of the present application, and the implementation environment provides a communication network, the communication network includes a route reflector group and multiple network nodes, the route reflector group includes route reflectors 001-003 (that is, route reflectors 001, 002, and 003), and the multiple network nodes include network nodes 011-016 (that is, network node 011, network node 012, network node 013, network node 014, network node 015, and network node 016). Among them, each route reflector in route reflectors 001-003 has a transmission channel established with at least one route reflector in the route reflector group. Optionally, each route reflector in route reflectors 001-003 has a transmission channel established with all route reflectors in the route reflector group, and the transmission channel between each route reflector and other route reflectors in the route reflector group can be a direct transmission channel and/or an indirect transmission channel. For example, a direct transmission channel is established between route reflector 001 and route reflector 002, and an indirect transmission channel is established between route reflector 001 and route reflector 002 (the indirect transmission channel is composed of a direct transmission channel between route reflector 001 and route reflector 003, and a direct transmission channel between route reflector 003 and route reflector 002). For another example, a direct transmission channel is established between route reflector 002 and route reflector 003, and an indirect transmission channel is established between route reflector 002 and route reflector 003 (the indirect transmission channel is composed of a direct transmission channel between route reflector 002 and route reflector 001, and a direct transmission channel between route reflector 001 and route reflector 003). As shown in FIG. 1, the embodiment of the present application is described by taking the example of direct transmission channels established between route reflectors 001 to 003. In the embodiment of the present application, the transmission channel can be a VPN tunnel, for example, an Auto VPN tunnel, and the transmission channel can be used to transmit data, so the transmission channel can also be called a data channel.
其中，路由反射器可以是CPE、uCPE或vCPE，该路由反射器组可以是一群部署在不同物理位置的CPE、vCPE和/或uCPE，通过共享传输网络信息和业务网络信息来管理网络节点的集合。实际应用中，可以根据通信网络中网络节点的多少(或者根据通信网络的规模)，扩大或缩小该路由反射器组的规模。The route reflector may be a CPE, uCPE or vCPE, and the route reflector group may be a group of CPEs, vCPEs and/or uCPEs deployed at different physical locations, which manages a collection of network nodes by sharing transmission network information and service network information. In practical applications, the size of the route reflector group may be expanded or reduced according to the number of network nodes in the communication network (or according to the size of the communication network).
其中，网络节点又称为网络设备、网关设备、路由节点或路由设备等。网络节点011～016中的每个网络节点可以是CPE、uCPE或vCPE，并且网络节点可以是交换机或路由器(router)，网络节点011～016可以是相同的网络节点，例如，网络节点011～016均可以是CPE，或者，网络节点011～016可以是不同的网络节点，例如，网络节点011～016中的一部分为CPE，另一部分为uCPE，再一部分是vCPE，本申请实施例对此不做限定。Among them, the network node is also called a network device, a gateway device, a routing node or a routing device, etc. Each of the network nodes 011-016 may be a CPE, a uCPE or a vCPE, and the network node may be a switch or a router. The network nodes 011-016 may be the same network node, for example, the network nodes 011-016 may all be CPEs, or the network nodes 011-016 may be different network nodes, for example, a part of the network nodes 011-016 may be CPEs, another part may be uCPEs, and another part may be vCPEs, which is not limited in the embodiments of the present application.
在本申请实施例中，引入路由反射器组的概念，将通信网络中分布式部署的多个路由反射器视为路由反射器组，网络节点将路由反射器组视为高性能的路由反射器，向路由反射器组注册并建立传输通道，不同的网络节点均注册到路由反射器组上，路由反射器组中的不同路由反射器通过信息共享来反射不同网络节点的路由信息，使不同网络节点路由互通并建立传输通道，这样一来，无需对通信网络分区域管理，有助于解决目前分区域管理方案存在的技术问题。在本申请实施例中，路由反射器组中的每个路由反射器与该路由反射器组中的至少一个路由反射器之间建立有传输通道，通信网络中的每个网络节点可以根据路由反射器组的配置信息从路由反射器组中选择路由反射器并与其建立传输通道，通过传输通道向相应的路由反射器发送自身的路由信息，每个路由反射器可以将接收到的路由信息传输给与其建立传输通道的其他路由反射器，来与该其他路由反射器共享该路由信息，并且每个路由反射器可以将接收到的路由信息传输给与其建立传输通道的网络节点，如此一来，使得通信网络中的不同网络节点能够建立传输通道并基于传输通道通信。In the embodiment of the present application, the concept of a route reflector group is introduced, and multiple route reflectors distributedly deployed in a communication network are regarded as a route reflector group. The network node regards the route reflector group as a high-performance route reflector, registers with the route reflector group and establishes a transmission channel. Different network nodes are registered with the route reflector group. Different route reflectors in the route reflector group reflect the routing information of different network nodes through information sharing, so that the routes of different network nodes are interconnected and transmission channels are established. In this way, there is no need to manage the communication network in different regions, which helps to solve the technical problems existing in the current regional management scheme. In an embodiment of the present application, a transmission channel is established between each route reflector in a route reflector group and at least one route reflector in the route reflector group. Each network node in the communication network can select a route reflector from the route reflector group according to the configuration information of the route reflector group and establish a transmission channel with it, and send its own routing information to the corresponding route reflector through the transmission channel. Each route reflector can transmit the received routing information to other route reflectors with which the transmission channel is established to share the routing information with the other route reflectors, and each route reflector can transmit the received routing information to the network node with which the transmission channel is established. In this way, different network nodes in the communication network can establish a transmission channel and communicate based on the transmission channel.
示例地，以图1为例，网络节点011～016中的第一网络节点(该第一网络节点可以是网络节点011～016中的任一网络节点，例如网络节点011)可以获取路由反射器组的配置信息，根据该路由反射器组的配置信息从该路由反射器组中确定第一路由反射器(例如路由反射器001)，与该第一路由反射器建立传输通道，并通过与该第一路由反射器之间的传输通道向该第一路由反射器发送该第一网络节点的路由信息；该第一路由反射器接收到该第一网络节点的路由信息后，通过该第一路由反射器与该路由反射器组中的其他路由反射器(例如路由反射器002和路由反射器003)之间的传输通道，向该其他路由反射器发送该第一网络节点的路由信息，使得该路由反射器组中的不同路由反射器共享该第一网络节点的路由信息；该路由反射器组中的第二路由反射器(例如路由反射器002)接收到该第一网络节点的路由信息后，可以向与该第二路由反射器建立传输通道的其他网络节点(例如网络节点012～016中的至少一个)以及其他路由反射器发送该第一网络节点的路由信息；第二网络节点(例如网络节点012)接收到该第一网络节点的路由信息后，根据该第一网络节点的路由信息与该第一网络节点建立传输通道，使得该第一网络节点与该第二网络节点能够通过该传输通道传输数据。也即是，例如，最终可以在网络节点011与网络节点012之间建立传输通道，使网络节点011与网络节点012能够通过该传输通道传输数据。For example, taking FIG. 1 as an example, a first network node among network nodes 011 to 016 (the first network node may be any network node among network nodes 011 to 016, such as network node 011) may obtain configuration information of a route reflector group, determine a first route reflector (such as route reflector 001) from the route reflector group according to the configuration information of the route reflector group, establish a transmission channel with the first route reflector, and send routing information of the first network node to the first route reflector through the transmission channel between the first route reflector and the first route reflector; after the first route reflector receives the routing information of the first network node, the first route reflector transmits the routing information to the first route reflector through the transmission channel between the first route reflector and other route reflectors in the route reflector group (such as route reflectors 002 and 003). The first network node is sent to the other route reflectors, so that different route reflectors in the route reflector group share the routing information of the first network node; after receiving the routing information of the first network node, the second route reflector in the route reflector group (for example, route reflector 002) can send the routing information of the first network node to other network nodes (for example, at least one of network nodes 012 to 016) and other route reflectors that establish a transmission channel with the second route reflector; after receiving the routing information of the first network node, the second network node (for example, network node 012) establishes a transmission channel with the first network node according to the routing information of the first network node, so that the first network node and the second network node can transmit data through the transmission channel. That is, for example, a transmission channel can be finally established between network node 011 and network node 012, so that network node 011 and network node 012 can transmit data through the transmission channel.
需要指出的是，图1所示实施环境中的通信网络仅用于举例，并非用于限制本申请实施例的技术方案，在具体实现过程中，通信网络还可能包括其他设备，并且可以根据需要来配置网络节点的数量以及路由反射器组的规模。例如，该通信网络还可以包括控制器(图1中未示出)。其中，该控制器可以是AC，其是未来云化网络的大脑，融合了网络管理、业务控制和网络分析等功能，是实现网络资源池化、网络连接自动化和自优化以及运维自动化的核心使能系统。该控制器可以是部署在服务器中的功能模块，或者是一台服务器，或者由若干台服务器组成的服务器集群，或者是一个云计算服务中心，本申请实施例对此不做限定。It should be pointed out that the communication network in the implementation environment shown in Figure 1 is only used for example, and is not used to limit the technical solution of the embodiment of the present application. In the specific implementation process, the communication network may also include other devices, and the number of network nodes and the scale of the route reflector group can be configured as needed. For example, the communication network may also include a controller (not shown in Figure 1). Among them, the controller can be an AC, which is the brain of the future cloud network, integrating functions such as network management, business control and network analysis, and is a core enabling system for realizing network resource pooling, network connection automation and self-optimization, and operation and maintenance automation. The controller can be a functional module deployed in a server, or a server, or a server cluster composed of several servers, or a cloud computing service center, which is not limited by the embodiment of the present application.

示例地，第一网络节点的设备标识可以为ID-A，路由反射器组中的路由反射器的数量为3，假设该第一网络节点计算出该ID-A与3的哈希值为1，则第一网络节点确定目标序列号为1，该第一网络节点将上述路由反射器序列1确定为目标序列。也即是，目标序列为：路由反射器001、路由反射器002、路由反射器003。For example, the device identifier of the first network node may be ID-A, and the number of route reflectors in the route reflector group is 3. Assuming that the first network node calculates that the hash value of ID-A and 3 is 1, the first network node determines that the target sequence number is 1, and the first network node determines the route reflector sequence 1 as the target sequence. That is, the target sequence is: route reflector 001, route reflector 002, route reflector 003.
需要说明的是，本申请实施例所描述的第一网络节点确定目标序列的方式仅仅是示例性的，本领域技术人员应当明白，实际应用中，第一网络节点还可以通过其他方式确定目标序列，例如，第一网络节点从至少一个路由反射器序列中随机选择一个路由反射器序列作为目标序列，本申请实施例不对第一网络节点确定目标序列的方式进行限定。It should be noted that the manner in which the first network node determines the target sequence described in the embodiment of the present application is merely exemplary. Those skilled in the art should understand that in actual applications, the first network node may also determine the target sequence in other ways. For example, the first network node randomly selects a route reflector sequence from at least one route reflector sequence as the target sequence. The embodiment of the present application does not limit the manner in which the first network node determines the target sequence.
子步骤2024a、根据该目标序列，从该路由反射器组中确定第一路由反射器。Sub-step 2024a: Determine a first route reflector from the route reflector group according to the target sequence.
第一网络节点确定出目标序列后，可以根据该目标序列从该路由反射器组中确定第一路由反射器。可选地，第一网络节点可以将该目标序列中的首个(也即是第一个)路由反射器确定为第一路由反射器。After the first network node determines the target sequence, it can determine the first route reflector from the route reflector group according to the target sequence.

示例地，目标序列为：路由反射器001、路由反射器002、路由反射器003，该目标序列中的首个路由反射器为路由反射器001，则第一网络节点可以将路由反射器001确定为第一路由反射器。For example, the target sequence is: route reflector 001, route reflector 002, route reflector 003, and the first route reflector in the target sequence is route reflector 001. Then the first network node can determine route reflector 001 as the first route reflector.
第三种实现方式：第一网络节点根据路由反射器组的配置信息，以智能选举的方式从该路由反射器组中确定第一路由反射器。A third implementation manner: the first network node determines the first route reflector from the route reflector group in an intelligent election manner according to the configuration information of the route reflector group.
在智能选举的方式中，第一网络节点根据第一网络节点与路由反射器组中的各个路由反射器之间的通信链路的质量确定第一路由反射器。可选地，请参考图4，其示出了本申请实施例提供的一种第一网络节点以智能选举的方式从路由反射器组中确定第一路由反射器的方法流程图，参见图4，该方法可以包括如下子步骤：In the intelligent election method, the first network node determines the first route reflector according to the quality of the communication link between the first network node and each route reflector in the route reflector group. Optionally, please refer to Figure 4, which shows a flow chart of a method provided by an embodiment of the present application for a first network node to determine the first route reflector from the route reflector group in an intelligent election method. Referring to Figure 4, the method may include the following sub-steps:
子步骤2021b、根据路由反射器组的配置信息，获取第一网络节点与该路由反射器组中的每个路由反射器之间的通信链路的链路质量。Sub-step 2021b: acquiring, according to the configuration information of the route reflector group, the link quality of the communication link between the first network node and each route reflector in the route reflector group.
可选地，第一网络节点与路由反射器组中的每个路由反射器之间建立有通信链路，第一网络节点可以对该第一网络节点与每个路由反射器之间的通信链路进行质量检测，获取该第一网络节点与该每个路由反射器之间的通信链路的链路质量。其中，该链路质量可以包括链路时延、链路抖动或链路丢包率中的至少一种。Optionally, a communication link is established between the first network node and each route reflector in the route reflector group, and the first network node may perform quality detection on the communication link between the first network node and each route reflector to obtain the link quality of the communication link between the first network node and each route reflector. The link quality may include at least one of link delay, link jitter, or link packet loss rate.
可选地，第一网络节点可以采用目前使用的各种链路检测技术检测通信链路的链路质量，例如，第一网络节点可以采用存活检测机制(keepalive，KA)技术、双向转发检测(bidirectionalforwarding detection，BFD)技术或IP流性能管理(flow performancemanagement，FPM)技术等检测通信链路的链路质量。Optionally, the first network node can adopt various currently used link detection technologies to detect the link quality of the communication link. For example, the first network node can adopt the keepalive (KA) technology, bidirectional forwarding detection (BFD) technology or IP flow performance management (FPM) technology to detect the link quality of the communication link.
以采用KA技术检测通信链路的链路质量为例，在本申请实施例中，对于路由反射器组中的每个路由反射器(例如路由反射器001)，在每个检测周期内，第一网络节点通过第一网络节点与该路由反射器(例如路由反射器001)之间的通信链路，向该路由反射器(例如路由反射器001)发送检测报文，并接收该路由反射器(例如路由反射器001)针对该检测报文发送的响应报文，根据该响应报文的接收时间戳以及该检测报文的发送时间戳，确定该通信链路的链路时延。根据第一检测报文的发送时间戳和第一响应报文的接收时间戳的时间差，以及第二检测报文的发送时间戳和第二响应报文的接收时间戳的时间差，确定该通信链路的链路抖动，其中，该第一检测报文和该第二检测报文为同一检测周期内的任意两个检测报文，该第一响应报文为该路由反射器(例如路由反射器001)针对该第一检测报文发送的响应报文，该第二响应报文为该路由反射器(例如路由反射器001)针对该第二检测报文发送的响应报文。根据每个检测周期内发送的检测报文的数量和接收的响应报文的数量，确定该通信链路的链路丢包量，进而根据该链路丢包量和该检测周期内发送的检测报文的数量确定该通信链路的链路丢包率。本领域技术人员应当明白，本段所描述的检测通信链路的链路质量的方式仅仅是示例性的，实际应用中，第一网络节点还可以采用其他方式检测通信链路的链路质量，本申请实施例在此不再赘述。Taking the use of KA technology to detect the link quality of a communication link as an example, in an embodiment of the present application, for each route reflector (e.g., route reflector 001) in the route reflector group, within each detection cycle, the first network node sends a detection message to the route reflector (e.g., route reflector 001) through the communication link between the first network node and the route reflector (e.g., route reflector 001), and receives a response message sent by the route reflector (e.g., route reflector 001) for the detection message, and determines the link delay of the communication link based on the reception timestamp of the response message and the sending timestamp of the detection message. According to the time difference between the sending timestamp of the first detection message and the receiving timestamp of the first response message, and the time difference between the sending timestamp of the second detection message and the receiving timestamp of the second response message, the link jitter of the communication link is determined, wherein the first detection message and the second detection message are any two detection messages in the same detection cycle, the first response message is the response message sent by the route reflector (e.g., route reflector 001) for the first detection message, and the second response message is the response message sent by the route reflector (e.g., route reflector 001) for the second detection message. According to the number of detection messages sent in each detection cycle and the number of response messages received, the link packet loss amount of the communication link is determined, and then the link packet loss rate of the communication link is determined according to the link packet loss amount and the number of detection messages sent in the detection cycle. It should be understood by those skilled in the art that the method of detecting the link quality of the communication link described in this paragraph is only exemplary. In actual applications, the first network node can also detect the link quality of the communication link in other ways, and the embodiments of the present application will not be repeated here.
子步骤2022b、根据第一网络节点与该路由反射器组中的各个路由反射器之间的通信链路的链路质量，从该路由反射器组中确定第一路由反射器。Sub-step 2022b: Determine a first route reflector from the route reflector group according to link qualities of communication links between the first network node and each route reflector in the route reflector group.
可选地，第一网络节点可以根据该第一网络节点与该路由反射器组中的每个路由反射器之间的通信链路的链路质量，确定该第一网络节点与该每个路由反射器之间的通信链路的综合度量指标(composite measure indicator，CMI)，根据该第一网络节点与该路由反射器组中的各个路由反射器之间的通信链路的综合度量指标，从该路由反射器组中确定第一路由反射器。其中，该综合度量指标用于表征通信链路的综合链路质量，综合度量指标越大，表示通信链路的综合链路质量越好，综合度量指标越小，表示通信链路的综合链路质量越差。可选地，第一网络节点将综合度量指标最高的通信链路对应的路由反射器确定为第一路由反射器。也即是，第一网络节点将路由反射器组中，与第一网络节点之间的通信链路的综合度量指标最高的路由反射器确定为第一路由反射器。Optionally, the first network node may determine a composite measure indicator (CMI) of the communication link between the first network node and each route reflector in the route reflector group according to the link quality of the communication link between the first network node and each route reflector in the route reflector group, and determine the first route reflector from the route reflector group according to the composite measure indicator of the communication link between the first network node and each route reflector in the route reflector group. The composite measure indicator is used to characterize the composite link quality of the communication link, and the larger the composite measure indicator, the better the composite link quality of the communication link, and the smaller the composite measure indicator, the worse the composite link quality of the communication link. Optionally, the first network node determines the route reflector corresponding to the communication link with the highest composite measure indicator as the first route reflector. That is, the first network node determines the route reflector with the highest composite measure indicator of the communication link between the first network node and the route reflector group as the first route reflector.
可选地，该链路质量可以包括链路时延、链路抖动或链路丢包率中的至少一种，第一网络节点可以根据第一网络节点与每个路由反射器之间的通信链路的链路质量，采用综合度量指标公式确定该第一网络节点与该每个路由反射器之间的通信链路的综合度量指标。也即是，第一网络节点可以将该第一网络节点与该每个路由反射器之间的通信链路的链路时延、链路抖动或链路丢包率中的至少一种，代入该综合度量指标公式，通过该综合度量指标公式进行计算，得到该第一网络节点与该每个路由反射器之间的通信链路的综合度量指标。Optionally, the link quality may include at least one of link delay, link jitter or link packet loss rate, and the first network node may determine the comprehensive metric index of the communication link between the first network node and each route reflector according to the link quality of the communication link between the first network node and each route reflector using a comprehensive metric index formula. That is, the first network node may substitute at least one of the link delay, link jitter or link packet loss rate of the communication link between the first network node and each route reflector into the comprehensive metric index formula, and calculate through the comprehensive metric index formula to obtain the comprehensive metric index of the communication link between the first network node and each route reflector.
其中，综合度量指标公式可以为：C＝9000-[min(k1×D，Dmax)+min(k2×J，Jmax)+min(k3×L，Lmax)]，C表示综合度量指标，D表示链路时延，J表示链路抖动，L表示链路丢包率，Dmax表示链路时延的最大值，Jmax表示链路抖动的最大值，Lmax表示链路丢包率的最大值，k1、k2和k3均为常数，min(k1×D，Dmax)表示取k1×D和Dmax中的较小者，min(k2×J，Jmax)表示取k2×J和Jmax中的较小者，min(k3×L，Lmax)表示取k3×L和Lmax中的较小者。其中，k1、k2和k3的缺省值分别为1，也即是，[min(k1×D，Dmax)+min(k2×J，Jmax)+min(k3×L，Lmax)]缺省定义为[min(D，Dmax)+min(J，Jmax)+min(L，Lmax)]。k1、k2和k3的取值可以根据实际业务需求设置，例如，k1＝1，k2＝10，k3＝1，则该综合度量指标公式可以为：C＝9000-[min(D，Dmax)+min(10×J，Jmax)+min(L，Lmax)]。需要说明的是，通常情况下，k1×D≤Dmax，k2×J≤Jmax，k3×L≤Lmax，则前述综合度量指标公式可以简化为：C＝9000-(k1×D+k2×J+k3×L)，其中，Dmax＝5000毫秒，Jmax＝3000毫秒，Lmax＝1000‰(‰表示千分之，为链路丢包率的单位)。Among them, the comprehensive measurement index formula can be: C=9000-[min(k1×D, Dmax)+min(k2×J, Jmax)+min(k3×L, Lmax)], C represents the comprehensive measurement index, D represents the link delay, J represents the link jitter, L represents the link packet loss rate, Dmax represents the maximum value of the link delay, Jmax represents the maximum value of the link jitter, Lmax represents the maximum value of the link packet loss rate, k1, k2 and k3 are all constants, min(k1×D, Dmax) represents the smaller of k1×D and Dmax, min(k2×J, Jmax) represents the smaller of k2×J and Jmax, and min(k3×L, Lmax) represents the smaller of k3×L and Lmax. The default values of k1, k2 and k3 are 1 respectively, that is, [min(k1×D, Dmax)+min(k2×J, Jmax)+min(k3×L, Lmax)] is defined by default as [min(D, Dmax)+min(J, Jmax)+min(L, Lmax)]. The values of k1, k2 and k3 can be set according to actual business needs. For example, k1=1, k2=10, k3=1, then the comprehensive measurement indicator formula can be: C=9000-[min(D, Dmax)+min(10×J, Jmax)+min(L, Lmax)]. It should be noted that, under normal circumstances, k1×D≤Dmax, k2×J≤Jmax, k3×L≤Lmax, then the aforementioned comprehensive measurement indicator formula can be simplified to: C=9000-(k1×D+k2×J+k3×L), wherein Dmax=5000 milliseconds, Jmax=3000 milliseconds, Lmax=1000‰ (‰ means thousandth, which is the unit of link packet loss rate).
需要说明的是，该综合度量指标公式中同时包括链路时延，链路抖动和链路丢包率，实际应用中，第一网络节点可能获取到链路时延，链路抖动和链路丢包率中的至少一个，并未同时获取到链路时延，链路抖动和链路丢包率，针对这种情况，第一网络节点在采用该综合度量指标公式计算通信链路的综合度量指标时，可以忽略未获取到的链路质量。例如，对于某条通信链路，若第一网络节点获取到该通信链路的链路时延和链路抖动，而未获取到该通信链路的链路丢包率，该第一网络节点可以忽略该通信链路的链路丢包率，采用公式C＝9000-[min(k1×D，Dmax)+min(k2×J，Jmax)]计算该通信链路的综合度量指标。再例如，对于某条通信链路，若第一网络节点获取到该通信链路的链路时延和链路丢包率，而未获取到该通信链路的链路抖动，该第一网络节点可以忽略该通信链路的链路抖动，采用C＝9000-[min(k1×D，Dmax)+min(k3×L，Lmax)]计算该通信链路的综合度量指标。又例如，对于某条通信链路，若第一网络节点获取到该通信链路的链路抖动和链路丢包率，而未获取到该通信链路的链路时延，该第一网络节点可以忽略该通信链路的链路时延，采用C＝9000-[min(k2×J，Jmax)+min(k3×L，Lmax)]计算该通信链路的综合度量指标。It should be noted that the comprehensive metric formula includes link delay, link jitter and link packet loss rate at the same time. In actual applications, the first network node may obtain at least one of the link delay, link jitter and link packet loss rate, but not obtain the link delay, link jitter and link packet loss rate at the same time. In this case, when the first network node uses the comprehensive metric formula to calculate the comprehensive metric of the communication link, it can ignore the unobtained link quality. For example, for a certain communication link, if the first network node obtains the link delay and link jitter of the communication link, but does not obtain the link packet loss rate of the communication link, the first network node can ignore the link packet loss rate of the communication link and use the formula C = 9000-[min(k1×D, Dmax)+min(k2×J, Jmax)] to calculate the comprehensive metric of the communication link. For another example, for a certain communication link, if the first network node obtains the link delay and link packet loss rate of the communication link, but fails to obtain the link jitter of the communication link, the first network node may ignore the link jitter of the communication link, and use C=9000-[min(k1×D, Dmax)+min(k3×L, Lmax)] to calculate the comprehensive metric of the communication link. For another example, for a certain communication link, if the first network node obtains the link jitter and link packet loss rate of the communication link, but fails to obtain the link delay of the communication link, the first network node may ignore the link delay of the communication link, and use C=9000-[min(k2×J, Jmax)+min(k3×L, Lmax)] to calculate the comprehensive metric of the communication link.
示例地，综合度量指标公式为C＝9000-(D+J+L)，路由反射器组包括路由反射器001～003，假设第一网络节点与路由反射器001之间的通信链路的链路质量包括：D＝10毫秒、J＝10毫秒，L＝10‰，则第一网络节点将D＝10毫秒、J＝10毫秒，L＝10‰代入综合度量指标公式C＝9000-(D+J+L)可以得到第一网络节点与路由反射器001之间的通信链路的综合度量指标为C＝8970。假设第一网络节点与路由反射器002之间的通信链路的链路质量包括：D＝20毫秒、J＝20毫秒，L＝20‰，则第一网络节点将D＝20毫秒、J＝20毫秒，L＝20‰代入综合度量指标公式C＝9000-(D+J+L)可以得到第一网络节点与路由反射器002之间的通信链路的综合度量指标为C＝8940。假设第一网络节点与路由反射器003之间的通信链路的链路质量包括：D＝30毫秒、J＝30毫秒，L＝30‰，则第一网络节点将D＝30毫秒、J＝30毫秒，L＝30‰代入综合度量指标公式C＝9000-(D+J+L)可以得到第一网络节点与路由反射器003之间的通信链路的综合度量指标为C＝8910。则容易理解，第一网络节点可以将该路由反射器组中的路由反射器001确定为第一路由反射器。For example, the comprehensive metric formula is C=9000-(D+J+L), the route reflector group includes route reflectors 001-003, and it is assumed that the link quality of the communication link between the first network node and the route reflector 001 includes: D=10 milliseconds, J=10 milliseconds, and L=10‰. The first network node substitutes D=10 milliseconds, J=10 milliseconds, and L=10‰ into the comprehensive metric formula C=9000-(D+J+L) to obtain a comprehensive metric of the communication link between the first network node and the route reflector 001 of C=8970. Assuming that the link quality of the communication link between the first network node and the route reflector 002 includes: D=20 milliseconds, J=20 milliseconds, L=20‰, the first network node substitutes D=20 milliseconds, J=20 milliseconds, L=20‰ into the comprehensive metric indicator formula C=9000-(D+J+L) to obtain the comprehensive metric indicator of the communication link between the first network node and the route reflector 002 as C=8940. Assuming that the link quality of the communication link between the first network node and the route reflector 003 includes: D=30 milliseconds, J=30 milliseconds, L=30‰, the first network node substitutes D=30 milliseconds, J=30 milliseconds, L=30‰ into the comprehensive metric indicator formula C=9000-(D+J+L) to obtain the comprehensive metric indicator of the communication link between the first network node and the route reflector 003 as C=8910. It is easy to understand that the first network node can determine the route reflector 001 in the route reflector group as the first route reflector.
步骤203、第一网络节点与该第一路由反射器建立传输通道。Step 203: The first network node establishes a transmission channel with the first route reflector.
第一网络节点确定第一路由反射器后，第一网络节点可以与该第一路由反射器建立传输通道。其中，该传输通道可以是VPN隧道，例如，Auto VPN隧道(基于Auto VPN技术建立的隧道)。After the first network node determines the first route reflector, the first network node may establish a transmission channel with the first route reflector, wherein the transmission channel may be a VPN tunnel, for example, an Auto VPN tunnel (a tunnel established based on the Auto VPN technology).
可选地，第一网络节点可以向第一路由反射器发送注册报文，该注册报文可以携带该第一网络节点的设备标识，第一路由反射器接收到该注册报文后，记录该第一网络节点的设备标识，并向第一网络节点发送响应报文，该响应报文携带该第一路由反射器的设备信息(例如设备标识)，以示该第一路由反射器与该第一网络节点之间的数据报安全传输协议(datagram transport level security，DTLS)管理通道建立成功。之后，该第一网络节点与该第一路由反射器通过二者之间的该DTLS管理通道获取彼此的传输网络信息(例如公网地址)，并基于彼此的传输网络信息，在该第一网络节点与该第一路由反射器之间建立传输通道。Optionally, the first network node may send a registration message to the first route reflector, and the registration message may carry the device identifier of the first network node. After receiving the registration message, the first route reflector records the device identifier of the first network node and sends a response message to the first network node, and the response message carries the device information (e.g., device identifier) of the first route reflector, indicating that the datagram transport level security (DTLS) management channel between the first route reflector and the first network node is successfully established. Afterwards, the first network node and the first route reflector obtain each other's transmission network information (e.g., public network address) through the DTLS management channel between the two, and establish a transmission channel between the first network node and the first route reflector based on each other's transmission network information.
步骤204、第一网络节点激活第一网络节点与该第一路由反射器之间的对等体。Step 204: The first network node activates a peer relationship between the first network node and the first route reflector.
其中，该第一网络节点与该第一路由反射器之间的对等体可以是BGP对等体。The peers between the first network node and the first route reflector may be BGP peers.
可选地，第一网络节点中具有该第一网络节点与第一路由反射器之间的对等体，第一网络节点中的该对等体可以处于激活状态或非激活状态，若第一网络节点中的该对等体处于非激活状态，在需要使用时，第一网络节点可以激活该对等体，使该对等体处于激活状态。可选地，第一网络节点可以在向第一路由反射器发送注册报文后，激活该第一网络节点与该第一路由反射器之间的对等体。本领域技术人员容易理解，若第一网络节点中与该第一网络节点与第一路由反射器之间的对等体处于激活状态，第一网络节点可以不用执行该步骤204。Optionally, the first network node has a peer between the first network node and the first route reflector, and the peer in the first network node can be in an activated state or an inactivated state. If the peer in the first network node is in an inactivated state, the first network node can activate the peer when it is needed to be used, so that the peer is in an activated state. Optionally, the first network node can activate the peer between the first network node and the first route reflector after sending a registration message to the first route reflector. It is easy for those skilled in the art to understand that if the peer between the first network node and the first route reflector in the first network node is in an activated state, the first network node may not perform step 204.
步骤205、第一路由反射器激活第一路由反射器与第一网络节点之间的对等体。Step 205: The first route reflector activates a peer between the first route reflector and the first network node.
其中，该第一路由反射器与该第一网络节点之间的对等体可以是BGP对等体。The peer between the first route reflector and the first network node may be a BGP peer.
可选地，第一路由反射器中可以具有该第一路由反射器与通信网络中的各个网络节点之间的对等体，第一路由反射器中的对等体可以处于激活状态或非激活状态，若第一路由反射器中的对等体处于非激活状态，在需要使用时，第一路由反射器可以激活该对等体，使该对等体处于激活状态。可选地，第一路由反射器可以在接收到第一网络节点发送的注册报文后，根据该注册报文中携带的第一网络节点的设备标识，激活该第一路由反射器与第一网络节点之间的对等体。例如，第一路由反射器根据该注册报文中携带的第一网络节点的设备标识，从第一路由反射器中确定该第一路由反射器与第一网络节点之间的对等体，然后激活该第一路由反射器与第一网络节点之间的对等体。本领域技术人员容易理解，若第一路由反射器中与该第一路由反射器与第一网络节点之间的对等体处于激活状态，第一路由反射器可以不用执行该步骤205。Optionally, the first route reflector may have peers between the first route reflector and each network node in the communication network, and the peers in the first route reflector may be in an activated state or an inactivated state. If the peer in the first route reflector is in an inactivated state, the first route reflector may activate the peer when it is needed to be used, so that the peer is in an activated state. Optionally, after receiving a registration message sent by the first network node, the first route reflector may activate the peer between the first route reflector and the first network node according to the device identifier of the first network node carried in the registration message. For example, the first route reflector determines the peer between the first route reflector and the first network node from the first route reflector according to the device identifier of the first network node carried in the registration message, and then activates the peer between the first route reflector and the first network node. It is easy for a person skilled in the art to understand that if the peers in the first route reflector and between the first route reflector and the first network node are in an activated state, the first route reflector may not perform step 205.
步骤206、第一网络节点与第一路由反射器建立对等体连接。Step 206: The first network node establishes a peer connection with the first route reflector.
第一网络节点激活第一网络节点与第一路由反射器之间的对等体，且第一路由反射器激活第一路由反射器与第一网络节点之间的对等体之后，第一网络节点与第一路由反射器可以建立对等体连接。After the first network node activates a peer between the first network node and the first route reflector, and the first route reflector activates a peer between the first route reflector and the first network node, the first network node and the first route reflector may establish a peer connection.
可选地，第一网络节点激活第一网络节点与第一路由反射器之间的对等体之后，第一网络节点中与第一路由反射器之间的对等体处于空闲(idle)状态(也即是初始状态)，第一路由反射器激活第一路由反射器与第一网络节点之间的对等体之后，第一路由反射器中与第一网络节点之间的对等体处于空闲状态，在空闲状态下，对等体拒绝邻居发送的连接请求。第一网络节点中的对等体在收到本设备(也即是第一网络节点)的开始(start)事件后，开始尝试与第一路由反射器中的对等体进行传输控制协议(transmission controlprotocol，TCP)连接，并转至连接(connect)状态。第一网络节点中的对等体在连接状态下，启动连接重试(connect retry)定时器，等待完成与第一路由反射器中的对等体的TCP连接。在第一网络节点中的对等体与第一路由反射器中的对等体的TCP连接成功之后，第一网络节点中的对等体向第一路由反射器中的对等体发送open(打开)报文，以与第一路由反射器中的对等体建立对等体连接，发送open报文后，第一网络节点中的对等体关闭连接重试定时器并转至opensent状态(open报文已发送状态)。第一网络节点中的对等体在opensent状态下，等待第一路由反射器中的对等体的open报文，并对接收到的open报文中的自治系统(autonomous system，AS)号、版本号、认证码等进行检查，以确定接收到的open报文是否正确。如果接收到的open报文正确，第一网络节点中的对等体向第一路由反射器中的对等体发送keepalive报文，以与第一路由反射器中的对等体保持对等体连接，发送keepalive报文后，第一网络节点中的对等体转至openconfirm状态(open报文已确认状态)。第一网络节点中的对等体在openconfirm状态下，等待第一路由反射器中的对等体的keepalive报文，如果接收到第一路由反射器中的对等体的keepalive报文，则转至established状态(连接已建立状态)，此时，第一网络节点与该第一路由反射器之间的对等体连接建立成功。Optionally, after the first network node activates the peer between the first network node and the first route reflector, the peer between the first network node and the first route reflector is in an idle state (that is, an initial state), and after the first route reflector activates the peer between the first route reflector and the first network node, the peer between the first route reflector and the first network node is in an idle state, and in the idle state, the peer rejects the connection request sent by the neighbor. After receiving the start event of the device (that is, the first network node), the peer in the first network node starts to try to establish a transmission control protocol (TCP) connection with the peer in the first route reflector, and switches to a connected state. In the connected state, the peer in the first network node starts a connection retry timer and waits for the completion of the TCP connection with the peer in the first route reflector. After the TCP connection between the peer in the first network node and the peer in the first route reflector is successful, the peer in the first network node sends an open message to the peer in the first route reflector to establish a peer connection with the peer in the first route reflector. After sending the open message, the peer in the first network node closes the connection retry timer and switches to the opensent state (open message sent state). In the opensent state, the peer in the first network node waits for the open message of the peer in the first route reflector, and checks the autonomous system (AS) number, version number, authentication code, etc. in the received open message to determine whether the received open message is correct. If the received open message is correct, the peer in the first network node sends a keepalive message to the peer in the first route reflector to maintain the peer connection with the peer in the first route reflector. After sending the keepalive message, the peer in the first network node switches to the openconfirm state (open message confirmed state). The peer in the first network node waits for a keepalive message from the peer in the first route reflector in the openconfirm state. If the keepalive message from the peer in the first route reflector is received, the state is changed to the established state (connection established state). At this time, the peer connection between the first network node and the first route reflector is successfully established.
步骤207、第一网络节点通过与该第一路由反射器之间的传输通道，向该第一路由反射器发送第一网络节点的路由信息。Step 207: The first network node sends the routing information of the first network node to the first route reflector through the transmission channel between the first network node and the first route reflector.
第一网络节点与第一路由反射器建立传输通道，且建立对等体连接之后，第一网络节点可以通过与该第一路由反射器之间的传输通道，向该第一路由反射器发送该第一网络节点的路由信息。可选地，该第一网络节点的路由信息可以包括该第一网络节点的IP地址和/或MAC地址，以及该第一网络节点的下一跳节点的标识，本申请实施例对此不做限定。可以理解的是，该对等体连接为该传输通道的上层连接，该传输通道为该对等体连接的底层通道，即通过该对等体连接发送的报文均通过该传输通道传输。以该对等体连接为BGP连接、该传输通道为VPN隧道为例，在通过该BGP连接传输该路由信息时，将该路由信息封装在BGP报文中作为该BGP报文的负载，进一步地，在通过该VPN隧道传输该BGP报文时，将该BGP报文封装在VPN隧道报文中作为该VPN隧道报文的负载。After the first network node establishes a transmission channel with the first route reflector and establishes a peer connection, the first network node may send the routing information of the first network node to the first route reflector through the transmission channel between the first network node and the first route reflector. Optionally, the routing information of the first network node may include the IP address and/or MAC address of the first network node, and the identifier of the next hop node of the first network node, which is not limited in the embodiment of the present application. It can be understood that the peer connection is an upper layer connection of the transmission channel, and the transmission channel is a bottom layer channel of the peer connection, that is, all messages sent through the peer connection are transmitted through the transmission channel. Taking the peer connection as a BGP connection and the transmission channel as a VPN tunnel as an example, when the routing information is transmitted through the BGP connection, the routing information is encapsulated in the BGP message as the load of the BGP message, and further, when the BGP message is transmitted through the VPN tunnel, the BGP message is encapsulated in the VPN tunnel message as the load of the VPN tunnel message.

Those skilled in the art should understand that the first network node can send any information that needs to be sent to the first route reflector to the first route reflector through the transmission channel between the first network node and the first route reflector, and the first route reflector can send any information that needs to be sent to the first network node to the first network node through the transmission channel between the first network node and the first network node, and the embodiment of the present application does not limit this. For example, the first network node can send the transmission network information of the first network node to the first route reflector through the transmission channel between the first network node and the first route reflector, and the first route reflector can also send the transmission network information of the first route reflector to the first network node through the transmission channel between the first network node and the first network node, so that the first network node and the first route reflector can obtain each other's transmission network information through the transmission channel.
步骤208、第一路由反射器将该第一网络节点的路由信息存储在该第一路由反射器的缓冲区中。Step 208: The first route reflector stores the routing information of the first network node in a buffer of the first route reflector.
对应于第一网络节点通过与第一路由反射器之间的传输通道向该第一路由反射器发送该第一网络节点的路由信息，第一路由反射器可以通过与该第一网络节点之间的传输通道接收该第一网络节点发送的该第一网络节点的路由信息。Corresponding to the first network node sending the routing information of the first network node to the first route reflector through the transmission channel between the first network node and the first route reflector, the first route reflector may receive the routing information of the first network node sent by the first network node through the transmission channel between the first network node and the first network node.
在本申请实施例中，路由反射器组中的每个路由反射器具有缓冲区(buffer)，该缓冲区用于缓冲向该路由反射器组共享的信息，该缓冲区的大小可以是固定的，且该缓冲区配置有计时器，每个路由反射器在接收到网络节点发送的信息后，可以将网络节点发送的信息存储至该缓冲区，并在该缓冲区中的信息总量达到该缓冲区的最大量和/或该缓冲区的计时器的计时时长达到目标时长时，将该缓冲区中所有信息发送给路由反射器组中的其他路由反射器，其中，缓冲区的大小以及目标时长均可以根据实际情况设置，示例地，缓冲区的大小为4096字节，目标时长为1秒。In an embodiment of the present application, each route reflector in the route reflector group has a buffer, which is used to buffer information shared with the route reflector group. The size of the buffer can be fixed, and the buffer is configured with a timer. After receiving the information sent by the network node, each route reflector can store the information sent by the network node in the buffer, and when the total amount of information in the buffer reaches the maximum amount of the buffer and/or the timing duration of the timer of the buffer reaches the target duration, all the information in the buffer is sent to other route reflectors in the route reflector group, wherein the size of the buffer and the target duration can be set according to actual conditions. For example, the size of the buffer is 4096 bytes and the target duration is 1 second.
在本申请实施例中，第一路由反射器接收到该第一网络节点的路由信息后，可以将该第一网络节点的路由信息存储在该第一路由反射器的缓冲区中。可选地，第一路由反射器可以将第一网络节点的路由信息写入该第一路由反射器的缓冲区，以将该第一网络节点的路由信息存储在该第一路由反射器的缓冲区中。In an embodiment of the present application, after receiving the routing information of the first network node, the first route reflector may store the routing information of the first network node in a buffer of the first route reflector. Optionally, the first route reflector may write the routing information of the first network node into the buffer of the first route reflector to store the routing information of the first network node in the buffer of the first route reflector.

If the first route reflector has not received the routing information, the first route reflector further detects whether it needs to forward the routing information. If the first route reflector has not received the routing information and needs to forward the routing information, the first route reflector stores the routing information of the first network node in the buffer of the first route reflector. Otherwise, the first route reflector can discard the routing information of the first network node. For example, if the first route reflector has received the routing information, the first route reflector can discard the routing information of the first network node, or if the first route reflector has not received the routing information but does not need to forward the routing information, the first route reflector can discard the routing information of the first network node. The embodiments of the present application do not limit this.

After receiving the route information of the first network node, the first route reflector may compare the route information with the recorded route information to detect whether the route information has been received. The first route reflector may have a route filtering rule. After receiving the route information of the first network node, the first route reflector may detect whether the route information needs to be forwarded according to the route filtering rule; optionally, if the route information meets the route filtering rule, the first route reflector may determine that the route information needs to be forwarded; if the route information does not meet the route filtering rule, the first route reflector may determine that the route information does not need to be forwarded.

Optionally, the first route reflector deletes the information in the buffer to clear the buffer, and the first route reflector resets the timing duration of the timer to reset the timer, for example, the first route reflector resets the timer to start the timing target duration from 0, or the first route reflector sets the countdown target duration of the timer, which is not limited in the embodiments of the present application.
步骤210、第二路由反射器通过该第二路由反射器与第一路由反射器之间的传输通道，接收该第一路由反射器发送的该第一网络节点的路由信息。Step 210: The second route reflector receives the routing information of the first network node sent by the first route reflector through a transmission channel between the second route reflector and the first route reflector.

That is, in step 209, the first route reflector sends the routing information of the first network node to the second route reflector through the transmission channel between the first route reflector and the second route reflector, and accordingly, in step 210, the second route reflector may receive the routing information of the first network node sent by the first route reflector through the transmission channel between the second route reflector and the first route reflector.
需要说明的是，路由反射器组中的路由反射器通过互传信息，可以实现路由反射器组中的不同路由反射器之间的信息共享，例如，第一路由反射器向第二路由反射器发送第一网络节点的路由信息，可以使第一路由反射器与第二路由反射器共享该第一网络节点的路由信息。本领域技术人员容易理解，在执行该步骤209至步骤210之前，第一路由反射器与第二路由反射器之间可以建立传输通道以及对等体连接，且在建立对等体连接之前，第一路由反射器和第二路由反射器可以分别激活各自的对等体。其中，第一路由反射器与第二路由反射器建立传输通道的过程可以参考前述步骤203，建立对等体连接的过程可以参考前述步骤206，激活对等体的过程可以参考步骤204和步骤205，本申请实施例在此不再赘述。It should be noted that the route reflectors in the route reflector group can realize information sharing between different route reflectors in the route reflector group by transmitting information to each other. For example, the first route reflector sends the routing information of the first network node to the second route reflector, so that the first route reflector and the second route reflector can share the routing information of the first network node. It is easy for those skilled in the art to understand that before executing steps 209 to 210, a transmission channel and a peer connection can be established between the first route reflector and the second route reflector, and before establishing the peer connection, the first route reflector and the second route reflector can activate their respective peers respectively. Among them, the process of establishing a transmission channel between the first route reflector and the second route reflector can refer to the aforementioned step 203, the process of establishing a peer connection can refer to the aforementioned step 206, and the process of activating a peer can refer to steps 204 and 205, which will not be repeated in the embodiments of the present application.
