图1示出了可以应用本公开的网络虚拟化的实现方法及装置的示例性架构100。FIG. 1 shows an
如图1所示，系统架构100可以包括服务器101、102、103，网络104和部署虚拟网络对应的服务器集群105。服务器101、102、103之间通信连接构成拓扑网络，网络104用以在服务器101、102、103和服务器集群105之间提供通信链路的介质。网络104可以包括各种连接类型，例如有线、无线通信链路或者光纤电缆等等。As shown in FIG. 1 , the
服务器101、102、103通过网络104与服务器集群105交互，以接收或发送消息等。服务器101、102、103可以是支持网络连接从而进行数据交互和数据处理的硬件设备或软件。当服务器101、102、103为硬件时，其可以是支持网络连接，信息获取、交互、显示、处理等功能的各种服务器，包括但不限于裸金属服务器等物理服务器。当服务器101、102、103为软件时，可以安装在上述所列举的电子设备中。其可以实现成例如用来提供分布式服务的多个软件或软件模块，也可以实现成单个软件或软件模块。在此不做具体限定。
服务器集群105可以是提供虚拟网络服务的服务器集群。例如，通过智能交换机对服务器101、102、103发出的报文进行数据面处理，以在源服务器和目的服务器之间转发报文，实现物理服务器的网络虚拟化的后台处理服务器集群。作为示例，服务器105可以是云端服务器。
需要说明的是，服务器集群可以是硬件，也可以是软件。当服务器集群为硬件时，可以实现成多个服务器组成的分布式服务器集群。当服务器集群为软件时，可以实现成多个软件或软件模块(例如用来提供分布式服务的软件或软件模块)。在此不做具体限定。It should be noted that the server cluster can be hardware or software.

When the server cluster is software, it can be implemented as a plurality of software or software modules (eg, software or software modules for providing distributed services). There is no specific limitation here.
还需要说明的是，本申请的实施例所提供的网络虚拟化的实现方法可由服务器集群执行。相应地，网络虚拟化的实现装置包括的各个部分(例如各个单元)可以全部设置于服务器集群中。It should also be noted that, the implementation method of network virtualization provided by the embodiments of the present application may be executed by a server cluster. Correspondingly, each part (for example, each unit) included in the apparatus for implementing network virtualization may all be set in a server cluster.
应该理解，图1中的服务器、网络和服务器集群的数目仅仅是示意性的。根据实现需要，可以具有任意数目的服务器、网络和服务器集群。当网络虚拟化的实现方法运行于其上的电子设备不需要与其他电子设备进行数据传输时，该系统架构可以仅包括网络虚拟化的实现方法运行于其上的电子设备(例如服务器集群)。It should be understood that the numbers of servers, networks and server clusters in FIG. 1 are merely illustrative. There can be any number of servers, networks, and server clusters depending on the implementation needs. When the electronic device on which the implementation method of network virtualization runs does not need to perform data transmission with other electronic devices, the system architecture may only include the electronic device (eg, server cluster) on which the implementation method of network virtualization runs.
请参考图2，图2为本公开实施例提供的一种网络虚拟化的实现方法的流程图，其中，流程200包括以下步骤：Please refer to FIG. 2 , which is a flowchart of a method for implementing network virtualization according to an embodiment of the present disclosure, wherein the
步骤201，获取待从源服务器转发至目的服务器的报文。Step 201: Obtain a packet to be forwarded from the source server to the destination server.
本实施例中，网络虚拟化的实现方法的执行主体(例如，图1中的服务器集群)可以获取待从源服务器转发至目的服务器的报文。In this embodiment, the execution body of the method for implementing network virtualization (for example, the server cluster in FIG. 1 ) may acquire the packets to be forwarded from the source server to the destination server.
源服务器与目的服务器相对应，其中，源服务器表征发出报文的服务器，目的服务器表征最终接收报文的服务器。需要说明的是，源服务器和目的服务器仅是针对于报文的转发过程涉及的服务器进行的区分性说明，在不同的转发过程中，相同的服务器可以担任源服务器、目的服务器多种角色。The source server corresponds to the destination server, wherein the source server represents the server that sends the message, and the destination server represents the server that finally receives the message. It should be noted that the source server and the destination server are only differentiated descriptions for the servers involved in the packet forwarding process. In different forwarding processes, the same server can play multiple roles of source server and destination server.
本实施例中，服务器可以是各种物理服务器。作为示例，服务器可以是裸金属服务器。裸金属服务器既拥有传统服务器的特点还具有云计算服务的功能。裸金属服务器可以视为升级过后的物理服务器，裸金属服务器仍然是租赁的，云服务提供商向租户提供一个裸金属服务器，对于该裸金属服务器，只有对应的唯一租户。In this embodiment, the server may be various physical servers. As an example, the server may be a bare metal server. Bare metal servers have both the characteristics of traditional servers and the functions of cloud computing services. The bare metal server can be regarded as an upgraded physical server. The bare metal server is still leased. The cloud service provider provides a bare metal server to the tenant. For the bare metal server, there is only one corresponding tenant.
对于每个服务器，上述执行主体可以为该服务器设置对应的智能交换机。每个智能交换机可以对应一个或多个服务器，当一个智能交换机对应多个服务器时，可以预先设置智能交换机的端口与相连的多个服务器的对应关系。For each server, the above-mentioned executive body may set a corresponding intelligent switch for the server. Each intelligent switch may correspond to one or more servers. When one intelligent switch corresponds to multiple servers, the corresponding relationship between the ports of the intelligent switch and the connected multiple servers may be preset.
当该服务器作为源服务器，发出报文时，该服务器对应的智能交换机可以接收该服务器发出的报文。其中，报文中携带有源服务器和目的服务器的IP(Internet Protocol，互联网协议)地址。When the server acts as a source server and sends a packet, the intelligent switch corresponding to the server can receive the packet sent by the server. The message carries IP (Internet Protocol, Internet Protocol) addresses of the source server and the destination server.
步骤202，通过源服务器对应的源智能交换机和目的服务器对应的目的智能交换机，确定表征虚拟网络中用于转发报文的虚拟通信路径的隧道规则。Step 202: Determine a tunnel rule representing a virtual communication path used for forwarding packets in the virtual network through the source intelligent switch corresponding to the source server and the destination intelligent switch corresponding to the destination server.
本实施例中，上述执行主体可以通过源服务器对应的源智能交换机和目的服务器对应的目的智能交换机，确定表征虚拟网络中用于转发报文的虚拟通信路径的隧道规则。其中，源智能交换机和目的智能交换机中的中央处理器通过多个报文收发单元与交换芯片通信连接。需要说明的是，源智能交换机和目的智能交换机均是智能交换机，仅是基于其所处的位置属性(例如源头、目的)进行的区分性描述。In this embodiment, the above-mentioned execution subject may determine a tunnel rule representing a virtual communication path used for forwarding packets in the virtual network through the source intelligent switch corresponding to the source server and the destination intelligent switch corresponding to the destination server. The central processing unit in the source intelligent switch and the destination intelligent switch communicates and connects with the switching chip through a plurality of message sending and receiving units. It should be noted that both the source smart switch and the destination smart switch are smart switches, and are only differentiated descriptions based on their location attributes (eg, source, destination).
具体的，智能交换机包括中央处理器、多个报文收发单元和交换芯片。报文收发单元为具有报文收发功能的处理单元，作为示例，报文收发单元为网卡。中央处理器和多个报文收发单元之间采用总线连接，而多个报文收发单元和交换芯片之间则采用以太网连接。总线例如可以是PCIE(peripheral component interconnect express，高速串行计算机扩展总线标准)总线。Specifically, the intelligent switch includes a central processing unit, a plurality of message sending and receiving units, and a switching chip. The message sending and receiving unit is a processing unit with a message sending and receiving function. As an example, the message sending and receiving unit is a network card. The central processing unit and the multiple message sending and receiving units are connected by bus, while the multiple message sending and receiving units and the switching chip are connected by Ethernet. The bus may be, for example, a PCIE (peripheral component interconnect express, high-speed serial computer expansion bus standard) bus.
在普通交换机，中央处理器并不做数据处理，仅仅具有管控的功能，因此采用性能较弱的型号即可，通常为嵌入式级别的中央处理器。而智能交换机的中央处理器则需要参与数据处理，因此，需要采用性能强大的型号，通常为服务器级别的中央处理器。In ordinary switches, the central processing unit does not do data processing, but only has the function of management and control. Therefore, a model with weaker performance can be used, usually an embedded-level central processing unit. The central processing unit of the smart switch needs to participate in data processing, therefore, a model with powerful performance, usually a server-level central processing unit, is required.
本实施例中，虚拟网络例如是在Underlay网络上构建的Overlay网络。其中，Underlay网络是由各类物理设备构成，通过使用路由协议保证其设备之间的IP连通性的承载网络。Overlay网络是通过网络虚拟化技术，在同一张Underlay网络上构建出的一张或者多张虚拟的逻辑网络。不同的Overlay网络虽然共享Underlay网络中的设备和线路，但是Overlay网络中的业务与Underlay网络中的物理组网和互联技术相互解耦。In this embodiment, the virtual network is, for example, an Overlay network constructed on an Underlay network. Among them, the Underlay network is a bearer network that is composed of various physical devices, and uses routing protocols to ensure IP connectivity between the devices. Overlay network is one or more virtual logical networks constructed on the same Underlay network through network virtualization technology. Although different overlay networks share the devices and lines in the underlay network, the services in the overlay network are decoupled from the physical networking and interconnection technologies in the underlay network.
本实施例中，虚拟网络的网络控制器在管理虚拟网络的过程中，负责虚拟网络中节点的创建、删除、迁移、IP(Internet Protocol，互联网协议)地址的分配绑定等操作，并对管理过程中发生变化的节点对应的隧道规则进行调整，从而确定虚拟网络中的所有计算节点之间的全量隧道规则。在管理虚拟网络的过程中，网络控制器确定虚拟网络所涉及的隧道规则，并将隧道规则同步至各智能交换机。In this embodiment, in the process of managing the virtual network, the network controller of the virtual network is responsible for operations such as creation, deletion, migration, allocation and binding of IP (Internet Protocol, Internet Protocol) addresses in the virtual network, and management of the virtual network. Tunnel rules corresponding to nodes that have changed in the process are adjusted, so as to determine full tunnel rules between all computing nodes in the virtual network. In the process of managing the virtual network, the network controller determines the tunnel rules involved in the virtual network, and synchronizes the tunnel rules to each smart switch.
隧道表征在虚拟网络中的两个节点之间构建的一条虚拟通信路径。在路径的起点，把报文整体作为载荷封装在另一个外层报文头内部，然后在路径的终点，把添加的外层报文头再剥离。这样在起点和终点之间就可以使用外层报文头(具体为起点和终点的物理网络的IP地址)进行路由，而不需要修改内层的虚拟网络报文。隧道规则表征报文在虚拟通信路径的转发规则。A tunnel represents a virtual communication path built between two nodes in a virtual network. At the start of the path, the entire packet is encapsulated as a payload inside another outer header, and then at the end of the path, the added outer header is stripped. In this way, the outer packet header (specifically, the IP addresses of the physical network of the origin and the destination) can be used for routing between the origin and the destination, without modifying the inner virtual network packet. Tunnel rules represent packet forwarding rules on virtual communication paths.
通过源服务器发出的报文中携带的源服务器和目的服务器的IP地址，源智能交换机和目的智能交换机可以确定起点为源服务器、终点为目的服务器的隧道规则。Based on the IP addresses of the source server and the destination server carried in the packets sent by the source server, the source intelligent switch and the destination intelligent switch can determine the tunnel rule that the origin is the source server and the destination is the destination server.
在本实施例的一些可选的实现方式中，智能交换机中包括具有缓存一致性的多个中央处理器，多个中央处理器分别通过多个报文收发单元与交换芯片通信连接。In some optional implementation manners of this embodiment, the intelligent switch includes multiple central processing units with cache coherence, and the multiple central processing units are respectively connected to the switch chip in communication through multiple message sending and receiving units.
如图3所示，示出了智能交换机的结构示意图。智能交换机300中包括两个性能强大的中央处理器(简称为强中央处理器)301，每个强中央处理器均通过多个报文收发单元302与交换芯片303通信连接，并且，强中央处理器设置有大容量的内存(简称为大内存)304。As shown in FIG. 3 , a schematic structural diagram of an intelligent switch is shown. The
强中央处理器除了可以对接收到的报文进行数据面处理以外，基于智能交换机的内部结构，还具有以下功能：具有更宽的外设总线，可以连接更多的报文收发单元；具有更多的内存通道，可以连接更多的内存并使用更大的内存带宽；具有缓存一致性总线能力(如QPI/UPI等)，可以把多个强中央处理器连接起来。相比于普通交换机，智能交换机具备了更强的数据处理能力与存储能力，能够灵活地完成复杂的报文处理功能。In addition to processing the data plane of the received messages, the strong central processing unit also has the following functions based on the internal structure of the smart switch: it has a wider peripheral bus, which can connect more message sending and receiving units; More memory channels can connect more memory and use larger memory bandwidth; with cache coherence bus capability (such as QPI/UPI, etc.), it can connect multiple strong central processing units. Compared with ordinary switches, smart switches have stronger data processing and storage capabilities, and can flexibly complete complex packet processing functions.
智能交换机中的网卡，主要功能是帮助中央处理器快速收发报文，因此可以称为报文收发单元。一些现代的网卡芯片除了具有报文收发功能以外，本身也具备了一定的报文处理功能(如隧道报文的封装与解封装)。此时，网卡本身除了作为报文收发单元外，也可以作为报文处理单元。如此，可以减轻中央处理器的计算压力，进一步保证数据面转发的带宽和时延性能。同样是报文处理功能，网卡芯片相比于交换芯片的主要优势在于其可以通过DMA(Direct Memory Access，直接内存存取)引擎，直接读写内存中的数据，从而获得更大的存储空间。可以理解，本实现方式中，网卡的报文处理功能为非必须功能。The main function of the network card in the smart switch is to help the central processor to send and receive messages quickly, so it can be called a message sending and receiving unit. In addition to the function of sending and receiving packets, some modern network card chips also have certain packet processing functions (such as encapsulation and decapsulation of tunnel packets). At this time, the network card itself can also be used as a message processing unit in addition to serving as a message sending and receiving unit. In this way, the calculation pressure of the central processor can be reduced, and the bandwidth and delay performance of data plane forwarding can be further guaranteed. The same is the message processing function. The main advantage of the network card chip compared to the switch chip is that it can directly read and write data in the memory through the DMA (Direct Memory Access) engine, thereby obtaining a larger storage space. It can be understood that, in this implementation manner, the packet processing function of the network card is an optional function.
对于智能交换机的设计，从硬件形态上看，网卡既可以是内置的芯片，也可以是外插的标准卡。如果是前者，那么网卡芯片和交换芯片之间就可以直接在PCB(PrintedCircuit Board，印制电路板)上通过电信号互连。如果是后者，网卡和交换芯片之间需要通过线缆(光纤或铜缆等)进行互连，并占用智能交换机的外面板网口。本实施例中，可以根据实际情况具体选择网卡的硬件形态，在此不做限定。通过智能交换机强大的数据处理能力与存储能力，上述执行主体进行报文跟踪、统计。For the design of the intelligent switch, from the perspective of hardware form, the network card can be either a built-in chip or an externally inserted standard card. If it is the former, then the network card chip and the switching chip can be directly interconnected by electrical signals on a PCB (Printed Circuit Board, printed circuit board). If it is the latter, the network card and the switch chip need to be interconnected through cables (optical fibers or copper cables, etc.), and occupy the network ports on the outer panel of the smart switch. In this embodiment, the hardware form of the network card may be specifically selected according to the actual situation, which is not limited herein. Through the powerful data processing capability and storage capability of the intelligent switch, the above-mentioned executive body performs packet tracking and statistics.
本实现方式中，智能交换机具有强大的数据处理能力，可以支持超大规模的虚拟网络中的物理服务器的接入，也可以支持诸如报文连接跟踪、精确统计等云计算中重要的功能，提高了智能交换机的实用性，以及在大规模虚拟网络下的适用性。In this implementation, the smart switch has powerful data processing capabilities, can support access to physical servers in a super-large virtual network, and can also support important functions in cloud computing such as packet connection tracking, accurate statistics, etc. The practicality of smart switches and their applicability in large-scale virtual networks.
步骤203，通过源智能交换机和目的智能交换机，基于隧道规则，对报文进行数据面处理，并根据数据面处理结果，将报文从源服务器，经由虚拟网络，转发至目的服务器。
本实施例中，上述执行主体可以通过源智能交换机和目的智能交换机，基于隧道规则，对报文进行数据面处理，并将报文从源服务器，经由虚拟网络，转发至目的服务器。其中，数据面处理包括智能交换机的各不同端口上的各种类型的数据的处理和转发操作，包括但不限于是报文的封装、解封装、发送、接收等处理操作。对应的，数据面处理结果可以是在源智能交换机中对报文封装得到封装后报文，在目的智能交换机中对封装后报文解封装，得到原本的报文。In this embodiment, the above-mentioned executive body may process the data plane of the packet through the source intelligent switch and the destination intelligent switch based on tunnel rules, and forward the packet from the source server to the destination server via the virtual network.
