技术领域technical field
本申请涉及计算机技术领域，尤其涉及一种应用业务的迁移方法及系统、网络设备和存储介质。The present application relates to the field of computer technology, and in particular to a method and system for migrating application services, network equipment and storage media.
背景技术Background technique
计算机应用软件(简称应用)是提供业务的程序，服务器通过运行应用可以为终端提供相应业务。随着计算机被普遍应用于各行各业，应用为终端提供的业务涉及工程、金融和服务等诸多行业，许多通用应用也逐渐成为人们日常生活和社会交流中不可或缺的工具。应用迁移也称主机迁移，用于将某个应用(称作目标应用)从一个服务器(称作第一服务器)移动到另一个服务器(称作第二服务器)，从而使得第二服务器在运行目标应用的过程中为终端提供相应的业务。第一服务器和第二服务器可以为相同类型的服务器或者为不同类型的服务器。例如，应用迁移可以将应用从一个物理服务器迁移到另一个物理服务器，或者，将应用从物理服务器迁移到虚拟服务器，或者，将应用从一个虚拟服务器迁移到另一个虚拟服务器。Computer application software (abbreviated as application) is a program that provides services, and the server can provide corresponding services for the terminal by running the application. As computers are widely used in all walks of life, the services provided by applications for terminals involve many industries such as engineering, finance, and services. Many general-purpose applications have gradually become indispensable tools in people's daily life and social communication. Application migration, also known as host migration, is used to move an application (called the target application) from one server (called the first server) to another server (called the second server), so that the second server is running on the target During the application process, corresponding services are provided for the terminal. The first server and the second server may be the same type of server or different types of servers. For example, application migration can migrate an application from one physical server to another physical server, or migrate an application from a physical server to a virtual server, or migrate an application from one virtual server to another virtual server.
随着信息技术和企业业务的快速发展，应用迁移的频率不断增高。为了简化运维人员实施应用迁移的操作步骤，迁移服务中心应运而生。其中，参考图1，迁移服务中心是用于为用户(例如运维人员)提供应用迁移服务的服务器。用户可以通过配置迁移服务中心来向第一服务器发送迁移指令，以通知第一服务器向第二服务器迁移目标应用。With the rapid development of information technology and enterprise business, the frequency of application migration is increasing. In order to simplify the operation steps for operation and maintenance personnel to implement application migration, the Migration Service Center came into being. Wherein, referring to FIG. 1 , the migration service center is a server for providing application migration services for users (such as operation and maintenance personnel). The user can configure the migration service center to send a migration instruction to the first server, so as to notify the first server to migrate the target application to the second server.
为了将目标应用的部分或全部业务迁移至第二服务器，用户还需要对终端访问目标应用的通信网络进行改造(参考图1)或者对目标应用的客户端进行升级，以将终端访问目标应用的部分或全部流量迁移至第二服务器。可见，目前应用业务的迁移过程对用户的技术要求仍然较高，不利于降低应用业务迁移的成本。In order to migrate some or all of the services of the target application to the second server, the user also needs to modify the communication network through which the terminal accesses the target application (refer to FIG. 1 ) or upgrade the client of the target application so that the Some or all of the traffic is migrated to the second server. It can be seen that the current application service migration process still has high technical requirements for users, which is not conducive to reducing the cost of application service migration.

Compared with FIG. 2 , the network architecture corresponding to FIG. 1 is additionally equipped with a migration service center, and the migration server center is used to send a migration instruction to the first server under the instruction of the user, so as to realize application migration. In addition, in order to complete the service migration of the target application, the user needs to transform the forwarding network to realize the traffic migration of the target application.
用户可以通过二层网络扩展方案或分布式网关方案对转发网络进行改造。其中，二层网络扩展方案是指，被迁移主机(例如第一服务器)保持互联网协议(internetprotocol，IP)地址和物理地址不变，但是需要源端的二层广播域扩展到目的端，源端出口与目的端出口需支持建立二层隧道。被迁移主机的网关保持不变，与外部的互访都需要绕行到源端网关，即使跟它在同一个数据中心的主机。其中，分布式网关方案是指，被迁移主机保持IP地址和物理地址不变，同时在目的端部署和源端一样网关，这种网关通常称为分布式任播网关，主机可以在分布式网关部署站点任意移动。这个方案关键点是目的端网关能够将去往源端的流量转发到源端网关，目前技术是通过网关之间主机路由同步或在网关配置策略路由。Users can transform the forwarding network through the Layer 2 network expansion solution or the distributed gateway solution. Among them, the Layer 2 network expansion scheme refers to that the migrated host (such as the first server) keeps the Internet protocol (internet protocol, IP) address and physical address unchanged, but the Layer 2 broadcast domain at the source end needs to be extended to the destination end, and the source end exits The egress with the destination end needs to support the establishment of a layer 2 tunnel. The gateway of the migrated host remains unchanged, and all external visits need to bypass the source gateway, even if it is a host in the same data center as it. Among them, the distributed gateway solution means that the migrated host keeps the IP address and physical address unchanged, and at the same time deploys the same gateway as the source at the destination. This kind of gateway is usually called a distributed anycast gateway. The deployment site can be moved freely. The key point of this solution is that the destination gateway can forward the traffic to the source gateway to the source gateway. The current technology is to synchronize host routes between gateways or configure policy routing on the gateway.
无论是二层网络扩展方案还是分布式网关方案，现有的应用业务迁移方案需要用户对转发网络进行改造，以在源端与目的端之间建立直连网络或运营商专线，并且，终端访问目标应用的服务器地址需要改变，访问应用的终端和终端所在的网络均需要感知地址的改变并调整相应配置。可见，目前应用业务的迁移过程对用户的技术要求仍然较高，不利于降低应用业务迁移的成本。Whether it is a Layer 2 network expansion solution or a distributed gateway solution, the existing application service migration solution requires the user to modify the forwarding network to establish a direct network or operator dedicated line between the source end and the destination end, and the terminal access The server address of the target application needs to be changed, and both the terminal accessing the application and the network where the terminal is located need to sense the change of the address and adjust the corresponding configuration. It can be seen that the current application service migration process still has high technical requirements for users, which is not conducive to reducing the cost of application service migration.
为了降低应用业务迁移服务的成本，在本申请实施例中，由网关为用户提供应用迁移服务，将目标业务迁移至第二服务器。一方面，图1对应的网络架构中无需额外设置迁移服务中心，而是由网关根据用户的配置信息向第一服务器发送迁移指令，以将目标应用从第一服务器迁移至第二服务器，实现应用迁移。另一方面，网关可以根据用户的配置信息将访问目标业务的全部或部分流量转发到第二服务器，实现访问目标业务的流量迁移。In order to reduce the cost of the application business migration service, in the embodiment of the present application, the gateway provides the application migration service for the user, and migrates the target business to the second server. On the one hand, in the network architecture corresponding to Figure 1, there is no need to additionally set up a migration service center, but the gateway sends a migration command to the first server according to the user's configuration information to migrate the target application from the first server to the second server, realizing application migrate. On the other hand, the gateway can forward all or part of the traffic of the access target service to the second server according to the configuration information of the user, so as to realize the traffic migration of the access target service.

以下分别介绍网关根据配置信息接收第一流量和转发第一流量的过程。The process of receiving the first traffic and forwarding the first traffic by the gateway according to the configuration information is respectively introduced below.
一、网关根据配置信息接收第一流量1. The gateway receives the first traffic according to the configuration information
步骤S304中网关根据配置信息接收第一流量可以指，网关可以根据配置信息从接收到的所有流量中识别出第一流量。可选的，网关可以根据配置信息确定流量选择条件，之后，网关可以从接收到的流量中识别出满足该流量选择条件的流量(即第一流量)。In step S304, the gateway receiving the first traffic according to the configuration information may refer to that the gateway can identify the first traffic from all received traffic according to the configuration information. Optionally, the gateway may determine the traffic selection condition according to the configuration information, and then, the gateway may identify the traffic (that is, the first traffic) that satisfies the traffic selection condition from the received traffic.

可选的，配置信息可以包括迁移策略，用户通过迁移策略可以指示向第二服务器迁移目标业务的方式。可选的，网关可以根据配置信息中的迁移策略确定流量选择条件中的第二条件。Optionally, the configuration information may include a migration policy, through which the user may indicate a manner of migrating the target service to the second server. Optionally, the gateway may determine the second condition in the traffic selection condition according to the migration policy in the configuration information.
下面举例而非限定的介绍几种可能的迁移策略和相应的第二条件。The following introduces several possible migration strategies and corresponding second conditions by way of example and without limitation.
1、该迁移策略可以为搬迁驱动策略，搬迁驱动策略指示使用第二服务器代替第一服务器提供目标业务。相应的，第二条件可以为网关在将目标应用迁移至第二服务器后所接收到的流量。可选的，网关识别出的第一流量可以满足上述第一条件和/或第二条件。以流量选择条件包括上述第一条件和搬迁驱动策略对应的第二条件为例，第一流量可以为网关在将目标应用迁移至第二服务器后所接收到的访问目标业务的全部流量。1. The migration policy may be a relocation-driven policy, and the relocation-driven policy indicates that the second server is used instead of the first server to provide the target service. Correspondingly, the second condition may be the traffic received by the gateway after the target application is migrated to the second server. Optionally, the first traffic identified by the gateway may satisfy the foregoing first condition and/or second condition. Taking the traffic selection condition as an example including the above first condition and the second condition corresponding to the relocation driving strategy, the first traffic may be all traffic received by the gateway to access the target service after the target application is migrated to the second server.
2、迁移策略可以为流量分担策略，流量分担策略指示将第一服务器的部分业务迁移至第二服务器。相应的，第二条件用于从访问目标业务的全部流量中确定第二服务器对应的部分流量。下面结合2.1和2.2的内容举例而非限定的介绍几种可能的流量分担策略。2. The migration policy may be a traffic sharing policy, and the traffic sharing policy indicates to migrate part of the services of the first server to the second server. Correspondingly, the second condition is used to determine the part of the traffic corresponding to the second server from all the traffic of accessing the target service. The following introduces several possible traffic sharing strategies by combining the contents of 2.1 and 2.2 by way of example but not limitation.
2.1、迁移策略可以为流量驱动策略，流量驱动策略指示采用负载均衡方式向第二服务器迁移目标业务。相应的，第二条件可以为满足负载均衡策略。可选的，该负载均衡策略可以为迁移策略所指示的，或者为网关默认设置的。若迁移策略可以指示负载均衡策略，该负载均衡策略可以为用户在配置信息中自定义的，或者为用户从配置接口提供的多个预设负载均衡策略中选择的。以流量选择条件包括上述第一条件和流量驱动策略对应的第二条件为例，第一流量可以为根据负载均衡方式(对应于负载均衡策略)从全部流量中确定的，全部流量为网关在将目标应用迁移至第二服务器后所接收到的访问目标业务的全部流量。网关可以向第一服务器转发该全部流量中除第一流量以外的流量，以实现在目标应用迁移至第二服务器后将访问目标业务的流量负载均衡的转发给第一服务器和第二服务器。2.1. The migration policy may be a traffic-driven policy, and the traffic-driven policy indicates that the target service is migrated to the second server in a load balancing manner. Correspondingly, the second condition may be to satisfy a load balancing policy. Optionally, the load balancing policy may be indicated by the migration policy, or set by default by the gateway. If the migration policy can indicate a load balancing policy, the load balancing policy can be customized by the user in the configuration information, or selected by the user from multiple preset load balancing policies provided by the configuration interface. Take the traffic selection condition including the above first condition and the second condition corresponding to the traffic driving strategy as an example, the first traffic can be determined from all the traffic according to the load balancing method (corresponding to the load balancing strategy), and all the traffic is determined by the gateway in the future All traffic for accessing the target service received after the target application is migrated to the second server. The gateway may forward all the traffic except the first traffic to the first server, so that after the target application is migrated to the second server, the traffic for accessing the target service is load-balanced and forwarded to the first server and the second server.
2.2、该迁移策略可以为主备驱动策略，主备驱动策略指示在第一服务器发生故障后向第二服务器迁移目标业务。相应的，第二条件可以为第一服务器发生故障。以流量选择条件包括上述第一条件和流量驱动策略对应的第二条件为例，第一流量可以为网关在第一服务器发生故障后所接收到的访问目标业务的流量。在目标应用迁移至第二服务器后，在第一服务器发生故障前，网关可以继续向第一服务器转发接收到的访问目标业务的流量。2.2. The migration strategy may be an active/standby driving strategy, and the active/standby driving strategy indicates to migrate the target service to the second server after the first server fails. Correspondingly, the second condition may be that the first server fails. Taking the traffic selection condition including the above first condition and the second condition corresponding to the traffic driving policy as an example, the first traffic may be the traffic received by the gateway to access the target service after the first server fails. After the target application is migrated to the second server, before the first server fails, the gateway can continue to forward the received traffic for accessing the target service to the first server.
以上举例而非限定的介绍了第一流量所需满足的第一条件和第二条件，第一流量可以满足第一条件和/或第二条件，可选的，网络设备还可以确定第一流量所需满足的第一条件和第二条件以外的其他条件。The above describes the first condition and the second condition that the first flow needs to satisfy by way of example but not limitation. The first flow can satisfy the first condition and/or the second condition. Optionally, the network device can also determine the first flow Conditions other than the first condition and the second condition that need to be satisfied.
二、网关根据配置信息转发第一流量2. The gateway forwards the first traffic according to the configuration information
步骤S304中网关根据配置信息向第二服务器转发第一流量可以指，网关可以根据配置信息确定第一流量的目的地址指向第二服务器。可选的，网关根据配置信息确定第一流量的目的地址后，可以向该目的地址指向的设备(即第二服务器)发送第一流量。In step S304, forwarding the first traffic to the second server by the gateway according to the configuration information may mean that the gateway may determine that the destination address of the first traffic is directed to the second server according to the configuration information. Optionally, after the gateway determines the destination address of the first traffic according to the configuration information, it may send the first traffic to the device (that is, the second server) pointed to by the destination address.
可选的，配置信息可以携带目标业务的迁移目的端(即第二服务器)的地址，网关可以将配置信息中迁移目的端的地址作为第一流量的目的地址。Optionally, the configuration information may carry the address of the migration destination of the target service (that is, the second server), and the gateway may use the migration destination address in the configuration information as the destination address of the first traffic.
本申请实施例不限定网关所接收到的第一流量的目的地址所指向的设备。可选的，网关所接收到的第一流量的目的地址可以指向第一服务器或第二服务器。The embodiment of the present application does not limit the device to which the destination address of the first traffic received by the gateway points. Optionally, the destination address of the first traffic received by the gateway may point to the first server or the second server.
若网关所接收到的第一流量的目的地址指向第一服务器，本申请实施例不限定网关将第一流量转发给第二服务器的实现方式。作为举例而非限定，网关可以根据配置信息生成并保存重定向映射表。作为举例，该重定向映射表所表示的含义可以参考表1，表1是以网际协议版本4(internet protocol version 4，IPv4)网络举例说明，其他类型网络的处理逻辑可以参考IPv4网络的举例来理解，此处不再赘述。If the destination address of the first traffic received by the gateway points to the first server, this embodiment of the present application does not limit the implementation manner in which the gateway forwards the first traffic to the second server. As an example but not a limitation, the gateway may generate and save a redirection mapping table according to configuration information. As an example, the meaning represented by the redirection mapping table can refer to Table 1. Table 1 is an example of an Internet protocol version 4 (internet protocol version 4, IPv4) network, and the processing logic of other types of networks can refer to the example of an IPv4 network.

表1中，原始目的IP地址可以对应于配置信息所指示的迁移源端(即第一服务器)的地址，映射目的IP地址可以对应于配置信息所指示的迁移目的端(即第二服务器)的地址。网络设备根据配置信息生成并保存例如表1所示的重定向映射表后，可以按照双向替换原理对识别的第一流量进行转发，以保证第一流量转发的对称性。In Table 1, the original destination IP address may correspond to the address of the migration source (ie, the first server) indicated by the configuration information, and the mapped destination IP address may correspond to the address of the migration destination (ie, the second server) indicated by the configuration information. address. After the network device generates and saves the redirection mapping table shown in Table 1 according to the configuration information, it can forward the identified first traffic according to the bidirectional replacement principle, so as to ensure the symmetry of the first traffic forwarding.
表1中，“内层头”和“外层头”分别对应“隧道转发”和“非隧道转发”两种场景。In Table 1, "inner header" and "outer header" correspond to two scenarios of "tunnel forwarding" and "non-tunnel forwarding" respectively.
以网络设备接收到通过隧道转发技术发送的第一流量中的报文1和相应的回应报文2为例，如表1所示，假设原始目的IP地址和映射目的IP地址分别为“1.1.1.1”和“2.2.2.2”，由于目的地址和源地址封装在报文的内层头中，网络设备可以在接收到报文1后，解析报文1的内层头，将内层头中的目的地址(即“1.1.1.1”)替换为“2.2.2.2”，之后，在接收到报文2后解析报文2的内层头，将内层头中的目的地址(即“2.2.2.2”)替换为“1.1.1.1”。Taking the packet 1 and the corresponding response packet 2 received by the network device in the first traffic sent through the tunnel forwarding technology as an example, as shown in Table 1, it is assumed that the original destination IP address and the mapped destination IP address are "1.1. 1.1" and "2.2.2.2", since the destination address and source address are encapsulated in the inner header of the packet, the network device can parse the inner header of packet 1 after receiving packet 1, and The destination address (namely "1.1.1.1") is replaced with "2.2.2.2". After receiving message 2, the inner layer header of message 2 is parsed, and the destination address in the inner layer header (ie "2.2. 2.2") to "1.1.1.1".
以网络设备接收到通过非隧道转发技术发送的第一流量中的报文1和相应的回应报文2为例，如表1所示，假设原始目的IP地址和映射目的IP地址分别为“3.3.3.3”和“4.4.4.4”，由于目的地址和源地址封装在报文的外层头中，网络设备可以在接收到报文1后，解析报文1的外层头，将外层头中的目的地址(即“3.3.3.3”)替换为“4.4.4.4”，之后，在接收到报文2后解析报文2的外层头，将外层头中的目的地址(即“4.4.4.4”)替换为“3.3.3.3”。Taking the packet 1 and the corresponding response packet 2 received by the network device in the first traffic sent through the non-tunnel forwarding technology as an example, as shown in Table 1, it is assumed that the original destination IP address and the mapped destination IP address are respectively "3.3 .3.3" and "4.4.4.4", since the destination address and source address are encapsulated in the outer header of the packet, the network device can parse the outer header of packet 1 after receiving packet 1, and convert the outer header The destination address (namely "3.3.3.3") in the . .4.4") with "3.3.3.3".
就是说，网关可以根据配置信息生成重定向映射表，之后根据重定向映射表自动改写报文目的地址并自动转发。终端访问目标应用的服务器地址不需要改变，访问应用的终端不需要感知服务器地址的改变，相应的，也无需调整相应配置，有利于降低应用业务迁移的成本。That is to say, the gateway can generate a redirection mapping table according to the configuration information, and then automatically rewrite the destination address of the message according to the redirection mapping table and automatically forward it. The server address of the terminal accessing the target application does not need to be changed, and the terminal accessing the application does not need to perceive the change of the server address, and correspondingly, there is no need to adjust the corresponding configuration, which is beneficial to reduce the cost of application service migration.

Optionally, the process of the gateway forwarding the traffic 2 to the second server according to the configuration information can be understood with reference to the process of forwarding the first traffic introduced in the embodiment corresponding to FIG. 3 . For example, the gateway can determine the traffic 2_1 corresponding to the first server and the traffic 2_2 corresponding to the second server from the traffic 2 according to the load balancing policy, and then forward the traffic 2_1 according to the original forwarding table (excluding the redirection mapping table), and forward the traffic 2_1 according to the redirection table The mapping table changes the destination address of the traffic 2_2 accessing the target service to the address of the second server, so as to forward the traffic 2_2 to the second server.

并且，由于可以根据目标业务的流量来启动目标应用的迁移，有利于根据第一服务器运行的多个应用的业务流量来自动选择需要迁移的应用。由于可以根据用户的配置信息负载均衡的向第一服务器和第二服务器转发流量，有利于减轻第一服务器或第二服务器的业务压力。Moreover, since the migration of the target application can be started according to the traffic of the target business, it is beneficial to automatically select the application to be migrated according to the business traffic of multiple applications running on the first server. Since traffic can be load-balanced forwarded to the first server and the second server according to the configuration information of the user, it is beneficial to reduce the business pressure of the first server or the second server.
流量驱动策略对应的迁移方案支持根据流量负载动态触发应用迁移，例如，基于对第一服务器中运行的各应用流量进行统计监控，自动将流量较大的应用迁移至第二服务器，而对于流量较小的应用可以不迁移至第二服务器，有利于节约在第一服务器和第二服务器之间迁移应用所占用的网络资源和硬件资源，提升应用服务可靠性和可用性。The migration solution corresponding to the traffic-driven strategy supports dynamic triggering of application migration according to the traffic load. For example, based on statistical monitoring of the traffic of each application running on the first server, the application with large traffic is automatically migrated to the second server. Small applications may not be migrated to the second server, which is beneficial to save the network resources and hardware resources occupied by migrating applications between the first server and the second server, and improve the reliability and availability of application services.
