The invention provides an equivalent multipath ECMP switching method, network equipment and system, and relates to the technical field of communication, and the network equipment is provided with a plurality of service paths and a public standby service path, and maintains an ECMP group. The ECMP group comprises the plurality of service paths, and the method comprises: when determining that a fault service path exists in the plurality of service paths, determining a protection group corresponding to the fault service path according to an identifier of the fault service path; switching the fault service path into the public standby service path according to the service path identifier of the standby entry in the protection group corresponding to the fault service path, wherein the public standby service path is used for forwarding a service message on the fault service path; and updating the ECMP group to enable the ECMP group to contain the remaining service paths except the fault service path. Compared with the prior art, the invention can solve the problems of service interruption and large packet loss quantity when a fault service path exists in the ECMP group.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to an Equal-Cost Multipath ECMP switching method, network equipment and system. Background technique [0002] At present, in order to forward packets more efficiently, a tunnel (Tunnel) may be established in the network first, and then the packets are forwarded through the tunnel. The tunnel contains multiple paths for forwarding services, and the equal-cost multi-path (Equal CostMulti-Path, ECMP path) balancing strategy can realize the simultaneous forwarding of multiple services in multiple equal-cost service paths in the tunnel , improving the efficiency of multi-service forwarding. [0003] In actual use, when a faulty service path occurs in the tunnel, it is necessary to delete the faulty path first, and then redistribute multiple services on the faulty path to other equal-cost paths for forwarding. However, deleting the faulty path will easily cause the interru...
