Route convergence method and device, communication equipment and storage medium

Abstract

The embodiment of the invention relates to the field of communication, and discloses a routing convergence method and device, communication equipment and a storage medium. In the invention, the method comprises the steps of: adding a special processor in a node for processing flooding of a message, when the node receives a link state message containing link fault information, judging whether the link fault information exists in a storage area of the special processor or not, if so, not flooding the link state message, and if not, flooding the link state message to an adjacent node, and updating the link state database according to the link fault information and carrying out routing calculation and modification under the condition that data matched with the link fault information does not exist in the link state database. According to the invention, the special processor is used for performing flooding processing on the link state message, so that the time for performing single-time flooding on the node is shortened, the flooding time consumption of the whole network is reduced, the routing convergence speed is improved, and the influence of the routing convergence process on services is reduced.

Description

technical field [0001] The embodiment of the present invention relates to the communication field, and in particular to a route convergence method. Background technique [0002] In a packet transport network, a large number of deployed Layer 3 services need to be forwarded based on routes. When links or nodes in the network fail, route convergence is required. Routing convergence refers to the process that after the topology of the network changes, the routing table is re-established, sent, learned, and stabilized, and notifies all relevant routers in the network of the change. The discarding of service packets caused by this process will have a certain impact on related services. Many services cannot tolerate long-term packet loss, especially for services that are sensitive to packet loss. Long-term packet loss is unacceptable. [0003] At present, in the field of communication, the process of routing convergence in a network deploying a dynamic routing protocol generally ...

Problems solved by technology

[0004] However, the packet flooding speed in the routing convergence method of the prior art is slow, resulting in slow routing convergence speed; in addition, when the network scale is large and the number of routing entries is large, a large number of configurations need to be issued after routing calculation, resulting in slow routing convergence speed , the route convergence process has a great impact on the business
