Problems solved by technology

[0007] Since the forwarding information is much larger than the search information, the number of routes that can be synchronized in each synchronization cycle is limited, especially when there are multiple forwarding information in the route, this defect is more obvious, thus affecting the route convergence rate

Abstract

The invention provides a route synchronization method, a device and a communication system. The method comprises obtaining routing information which includes route prefix information and route forwarding information; and synchronizing the route prefix information and the route forwarding information with a receiving device separately according to a preset transmission order. Thus, by using an approach of separately synchronizing the route prefix information and the route forwarding information, the number of synchronized routes between devices in unit time is increased so as to achieve an effect of increasing the convergence rate of the routes.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a route synchronization method, device and communication system. Background technique [0002] In the era of rapid network development, users have higher and higher requirements for service quality. In the case of fast rerouting (FRR) protection, link failure or node failure, business traffic convergence time <50ms; without fast rerouting protection, business traffic convergence time <100ms. [0003] The fast rerouting protection technology is relatively mature and can well solve the problem of service packet loss during link switching. In the case of no protection, the time for service packet loss depends on the convergence rate of the routing protocol, that is, the routing convergence time. [0004] The route convergence time mainly includes: the time for the routing protocol to learn the route, the time for the routing protocol to deliver the route to the...
