Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] In the embodiment of the present application, a method for implementing equal-cost routing in a hybrid protocol network is provided. When any device in a hybrid protocol network calculates a route to a destination device, when the calculated route corresponding to the optimal routing protocol does not have a backup route When , the route corresponding to the optimal routing protocol and the route corresponding to the sub-optimal routing protocol are formed into an equivalent route and sent to the forwarding information base (Forwarding Information Base, FIB). Routes form equal-cost routes, which are used to load balance and forward traffic.

[0024] see figure 1 , figure 1 It is a schematic flowchart of a traffic forward...

Abstract

The present invention provides a traffic forwarding method in a mixed protocol networking, the method comprising: calculating the routes corresponding to each routing protocol to the destination device; When the route corresponding to the optimal routing protocol is selected, the route corresponding to the optimal routing protocol and the route corresponding to the sub-optimal routing protocol form an equivalent route and send the forwarding information base FIB; when receiving the route corresponding to the destination device For traffic, load balancing and forwarding are performed according to the equal-cost route described in the FIB. Based on the same inventive concept, this application also proposes a traffic forwarding device in a hybrid protocol network, which can form an equivalent route from routes calculated under different routing protocols in a hybrid network for load sharing and forwarding of traffic.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a flow forwarding method and device in a mixed protocol networking. Background technique [0002] In a traditional Internet Protocol (Internet Protocol, IP) network, a node selects the shortest path as a route to a destination device for calculation. In this way, traffic tends to concentrate on the shortest path and cause congestion, while other optional paths are relatively idle. [0003] Multiple routing protocols are running in a network. When a device calculates the route to the destination device, it will calculate multiple routes for multiple routing protocols. In the existing implementation, only routes calculated for different routing protocols will be selected. The route corresponding to the optimal routing protocol is used for traffic forwarding, and the route corresponding to the suboptimal routing protocol will not be used as an equivalent route. Therefore, th...
