报文路径选择的方法、装置、电子设备及介质Method, device, electronic device and medium for message path selection

技术领域technical field

本申请涉及通信技术领域，具体而言，涉及报文路径选择的方法、装置、电子设备及介质。The present application relates to the technical field of communication, and in particular, relates to a method, device, electronic equipment and medium for message path selection.

背景技术Background technique

在目标网关设备中存在多径路由的场景中，若请求报文的响应报文(即回复报文)的回复路径与该请求报文的请求路径不一致，则该响应报文通常无法到达正确的目的设备。这是由于网络环境中的安全防护设备通常会对传输报文的会话状态以及传输控制协议(TCP，Transmission Control Protocol)序列号进行检测。若传输报文的检测结果不符合预期，则会直接丢弃该传输报文，而若响应报文的回复路径与请求报文的请求路径不一致时，该响应报文通常无法通过安全防护设备的检测。In the scenario where there is multi-path routing in the target gateway device, if the reply path of the response packet (that is, the reply packet) of the request packet is inconsistent with the request path of the request packet, the response packet usually cannot reach the correct route. destination device. This is because the security protection equipment in the network environment usually detects the session state and Transmission Control Protocol (TCP, Transmission Control Protocol) sequence number of the transmitted message. If the detection result of the transmission message does not meet expectations, the transmission message will be discarded directly, and if the reply path of the response message is inconsistent with the request path of the request message, the response message usually cannot pass the detection of the security protection device .

现有技术下，通常通过链路时延以及带宽等方式进行路由的选择。但是，采用这种方式针对响应报文选择的回复路径，可能与请求路径不一致，进而导致响应报文被丢弃，报文路径选择的准确度较差。In the prior art, routing is usually selected by way of link delay and bandwidth. However, the reply path selected for the response message in this manner may not be consistent with the request path, which will cause the response message to be discarded, and the accuracy of message path selection is poor.

本申请实施例中，执行主体可以为包含多径路由的目标网关设备，目标网关设备可以为服务器，也可以为终端设备。In the embodiment of the present application, the execution subject may be a target gateway device including multipath routing, and the target gateway device may be a server or a terminal device.

本申请实施例可以应用于安全网关的路由设计中，一种应用场景中包括第一设备、多个中间网关设备、目标网关设备以及第二设备。目标网关设备的一个网络接口中配置了多个不同网段的互联网协议(Internet Protocol，IP)地址，并针对各IP地址，配置了相应的等价路由。The embodiments of the present application may be applied to routing design of a security gateway, and an application scenario includes a first device, multiple intermediate gateway devices, a target gateway device, and a second device. Multiple Internet Protocol (IP) addresses of different network segments are configured in a network interface of the target gateway device, and corresponding equivalent routes are configured for each IP address.

在请求报文的发送过程中，第一设备依次通过各中间网关设备中的某一中间网关设备以及目标网关设备，向第二设备发送请求报文。则在请求报文的请求路径中，上述某一中间网关设备为目标网关设备的上一跳网关设备。In the process of sending the request message, the first device sends the request message to the second device sequentially through a certain intermediate gateway device and the target gateway device among the intermediate gateway devices. Then, in the request path of the request message, one of the above-mentioned intermediate gateway devices is the last-hop gateway device of the target gateway device.

在响应报文的返回过程中，第二设备将响应报文发送至目标网关设备，若目标网关设备确定存在多径路由，则采用本申请实施例提供的报文路径选择的方法，基于上述上一跳网关设备的物理地址，确定下一跳网关设备的目标网关地址，并基于该目标网关地址，将响应报文发送给第一设备。In the process of returning the response message, the second device sends the response message to the target gateway device. If the target gateway device determines that there is a multi-path route, the method for selecting the message path provided by the embodiment of the present application is adopted, based on the above The physical address of the one-hop gateway device determines the target gateway address of the next-hop gateway device, and sends the response message to the first device based on the target gateway address.

下面结合图1对上述报文路径选择的方法的具体实施流程进行说明。参阅图1所示，为本申请实施例提供的一种报文路径选择的方法的流程图，该方法的具体实施流程如下：The specific implementation process of the method for selecting the packet path above will be described below with reference to FIG. 1 . Referring to Fig. 1, it is a flow chart of a method for message path selection provided by the embodiment of the present application, and the specific implementation process of the method is as follows:

步骤100：确定接收到基于请求报文返回的响应报文时，获得响应报文对应的多个下一跳网关地址；请求报文和响应报文是不同设备之间通过目标网关设备传输的报文；步骤101：确定各下一跳网关地址分别对应设置的第一物理地址；步骤102：获取请求报文对应的第二物理地址，第二物理地址是根据请求报文对应的上一跳网关设备确定的；步骤103：根据各第一物理地址以及第二物理地址，从各下一跳网关地址中筛选出用于传输响应报文的下一跳网关设备的目标网关地址。Step 100: When it is determined that the response message returned based on the request message is received, multiple next-hop gateway addresses corresponding to the response message are obtained; the request message and the response message are messages transmitted between different devices through the target gateway device Text; Step 101: Determine the first physical address corresponding to each next-hop gateway address; Step 102: Obtain the second physical address corresponding to the request message, and the second physical address is based on the previous hop gateway corresponding to the request message Determined by the device; Step 103: According to the first physical address and the second physical address, filter out the target gateway address of the next-hop gateway device for transmitting the response message from the next-hop gateway addresses.

其中，物理地址可以为物理地址(Media Access Control Address，MAC)，第一物理地址可以为第一MAC，第二物理地址可以为第二MAC。需要说明的是，物理地址用于在网络中唯一标识一个设备，在网络中具有唯一性。Wherein, the physical address may be a physical address (Media Access Control Address, MAC), the first physical address may be the first MAC, and the second physical address may be the second MAC. It should be noted that the physical address is used to uniquely identify a device in the network and is unique in the network.

为确定响应报文的返回路径是否与请求报文的请求路径一致，则可以在接收到请求报文时，先获取请求报文的第二物理地址，以确定传输该请求报文至目标网关设备的上一个网路设备，进而确定请求路径。In order to determine whether the return path of the response message is consistent with the request path of the request message, the second physical address of the request message can be obtained first when the request message is received, so as to determine whether to transmit the request message to the target gateway device The last network device in the network, and then determine the request path.

一种实施方式中，确定请求报文的第二物理地址时，可以采用以下步骤：确定接收到请求报文时，获取发送请求报文的上一跳网关设备；获取上一跳网关设备的出接口物理地址；将出接口物理地址，确定为第二物理地址。In one embodiment, when determining the second physical address of the request message, the following steps may be used: when determining that the request message is received, obtain the last-hop gateway device that sent the request message; obtain the outgoing address of the last-hop gateway device The physical address of the interface; the physical address of the outbound interface is determined as the second physical address.

作为一个示例，第一设备将请求报文发送至第二设备的过程中，第一设备先将请求报文发送至网关设备A(即目标网关设备的上一跳网关设备)。然后，网关设备A将接收的请求报文转发至目标网关设备。目标网关设备接收到该请求报文后，记录发送该请求报文的网关设备A的出接口物理地址，并将其确定为第二物理地址，以及，将请求报文转发至第二设备。As an example, when the first device sends the request packet to the second device, the first device first sends the request packet to gateway device A (that is, the last-hop gateway device of the target gateway device). Then, gateway device A forwards the received request message to the target gateway device. After receiving the request message, the target gateway device records the outgoing interface physical address of the gateway device A sending the request message, determines it as the second physical address, and forwards the request message to the second device.

进一步的，目标网关设备可以先通过内置的路由模块，检测是否存在多径路由，若是，则主动请求获取多径路由对应的地址解析协议(Address Resolution Protocol，ARP)表，即提前获取目标网关设备的ARP。Further, the target gateway device can first detect whether there is a multi-path route through the built-in routing module, and if so, actively request to obtain the Address Resolution Protocol (Address Resolution Protocol, ARP) table corresponding to the multi-path route, that is, obtain the target gateway device in advance the ARP.

在多径路由的场景中，目标网关设备中同时存在多条等价路由，进而可以在接收到响应报文时，确定多个下一跳网关地址。为确定各下一跳网关地址，步骤100的实现过程可以包括：In the scenario of multi-path routing, multiple equal-cost routes exist in the target gateway device at the same time, and then multiple next-hop gateway addresses can be determined when receiving the response message. In order to determine each next-hop gateway address, the implementation process ofstep 100 may include:

S1001：确定接收到响应报文时，获取响应报文的目的网络地址。S1001: Obtain the destination network address of the response message when it is determined that the response message is received.

具体的，目的网络地址为响应报文被发送的目标设备的网络地址。可选的，网络地址为IP地址。Specifically, the destination network address is the network address of the target device to which the response message is sent. Optionally, the network address is an IP address.

例如，第一设备将响应报文发送至第二设备的过程中，获取响应报文的目的网络地址，即第二设备的网络地址。For example, in the process of sending the response packet to the second device, the first device acquires the destination network address of the response packet, that is, the network address of the second device.

S1002：根据目的网络地址，从路由表中进行路由查询，获得目的网络地址对应的多个下一跳网关地址。进一步的，若确定不存在目的网络地址对应的下一跳网关地址，则表示该响应报文没有对应的路由进行转发，需要对其进行丢包处理，并结束该报文路径选择的流程。S1002: Perform routing query from the routing table according to the destination network address, and obtain multiple next-hop gateway addresses corresponding to the destination network address. Further, if it is determined that there is no next-hop gateway address corresponding to the destination network address, it means that the response message has no corresponding route for forwarding, and it needs to be discarded, and the message path selection process is ended.

具体的，下一跳网关地址为下一跳网关设备的网关IP地址。Specifically, the next-hop gateway address is the gateway IP address of the next-hop gateway device.

需要说明的是，每一网关地址均对应设置有物理地址。为确定下一跳网关地址对应的第一物理地址，步骤101的实现过程可以包括：It should be noted that each gateway address is correspondingly provided with a physical address. In order to determine the first physical address corresponding to the next-hop gateway address, the implementation process ofstep 101 may include:

获取地址映射关系，并根据该地址映射关系，获取各下一跳网关地址分别对应的第一物理地址。The address mapping relationship is obtained, and according to the address mapping relationship, the first physical addresses respectively corresponding to the next-hop gateway addresses are obtained.

其中，地址映射关系为网关地址与物理地址之间的对应关系。可选的，地址映射关系可以为地址解析协议(Address Resolution Protocol，ARP)表。Wherein, the address mapping relationship is a corresponding relationship between a gateway address and a physical address. Optionally, the address mapping relationship may be an Address Resolution Protocol (Address Resolution Protocol, ARP) table.

进一步的，若确定未获取到某一下一跳网关地址对应的第一物理地址，则舍弃该下一跳网关地址。Further, if it is determined that the first physical address corresponding to a certain next-hop gateway address has not been obtained, the next-hop gateway address is discarded.

作为一个示例，获取存储的ARP表；从ARP表中，分别获得每一个下一跳网关地址对应的第一MAC。As an example, the stored ARP table is obtained; from the ARP table, the first MAC corresponding to each next-hop gateway address is respectively obtained.

为获取与请求路径一致的返回路径，则需要准确地确定返回的下一跳网关设备的目标网关地址，为确定目标网关地址，步骤103的实现过程可以包括：In order to obtain a return path consistent with the request path, it is necessary to accurately determine the target gateway address of the returned next-hop gateway device. In order to determine the target gateway address, the implementation process ofstep 103 may include:

S1031:针对各第一物理地址中的目标跳转物理地址，将目标跳转物理地址与第二物理地址进行匹配；目标跳转物理地址为各第一物理地址中的任意一个。S1031: For the target jump physical address in each first physical address, match the target jump physical address with the second physical address; the target jump physical address is any one of the first physical addresses.

一种实施方式中，将目标跳转物理地址中的各字符，按照由前到后的顺序，依次与第二物理地址中的相应字符进行比较，若确定存在不一致的字符，则确定两者不匹配，停止针对目标跳转物理地址的地址匹配流程，若确定两者完全一致，则确定两者匹配。In one embodiment, the characters in the physical address of the target jump are compared with the corresponding characters in the second physical address in sequence from front to back, and if it is determined that there are inconsistent characters, it is determined that the two are not consistent. Matching, stop the address matching process for the physical address of the target jump, and if it is determined that the two are completely consistent, then it is determined that the two match.

S1032：若确定匹配成功，则将目标跳转物理地址对应的下一跳网关地址，确定为目标网关地址。S1032: If it is determined that the matching is successful, determine the next-hop gateway address corresponding to the target jump physical address as the target gateway address.

一种实施方式中，由于各第一物理地址中通常仅存在一个与第二物理地址匹配的第一物理地址，因此，若确定匹配成功，则说明目标跳转物理地址对应的下一跳网关设备为正确的返回路径的网关设备，并确定目标网关地址为目标跳转物理地址对应的下一跳网关地址，并停止匹配流程。若确定匹配失败，则说明目标跳转物理地址对应的下一跳网关设备不为正确的返回路径的网关设备，需要判断下一个第一物理地址对应的下一跳网关设备是否为正确的返回路径的网关设备，并执行S1031-S1032，直至确定匹配成功。In one embodiment, since there is usually only one first physical address that matches the second physical address in each first physical address, if it is determined that the match is successful, it indicates that the next-hop gateway device corresponding to the target jump physical address It is the gateway device of the correct return path, and the target gateway address is determined to be the next-hop gateway address corresponding to the target jump physical address, and the matching process is stopped.
