Problems solved by technology

[0006] The above solutions are not flexible and require manual selection and configuration. When the number of routes in the network is large, the configuration work will be very cumbersome, and it is not conducive to network expansion. At the same time, the problem of unbalanced traffic on the equal-cost path may occur

Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0025] In the embodiment of the present invention, a method for achieving consistent message forwarding paths is proposed, which is applied to a network including equivalent links. Network devices in the network are connected to equivalent links, and there may be inconsistencies in the round-trip paths. In the embodiment of the present invention, by configuring the port connected to the equivalent link of the network device, the port is enabled with the path unification function, while other ports are not enabled with this function, that is, the path unification function is not enabled.

Abstract

The invention discloses a method for achieving the consistency of message forwarding paths. The method comprises the steps that: if network equipment receives a message through a port which enables paths to be unified, a binding record is carried out on a hash calculation result obtained after the element information of the message is subjected to hash calculation and the port number of the port for receiving the message; if a message which is the same as the hash calculating result is received through the port which cannot enable the path to be unified, the message can be forwarded based on the binding record. On the basis of the same inventive concept, the invention also provides network equipment which can conveniently and flexibly achieve the consistency of the paths during forwarding the message and the capacity expansion of the network is not influenced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and network equipment for realizing consistent message forwarding paths. Background technique [0002] In some firewall services, when the internal network accesses the external network, it will be processed by some firewall devices. However, after these packets are processed by some devices on the external network, the response messages must also pass through the same firewall device to be processed correctly. , but there are often some equal-cost links in the network, and it is precisely because of these equal-cost links that the packets may not be unified on the forwarding path, that is, when they go out, they go through a firewall On the way back, the packet checked the routing table and took other equal-cost routes. As a result, the packet failed to be processed by the firewall when it did not go out. [0003] see figure 1 , figure 1 It is a schematic diag...
