Non-load-balancing route switching method and device

Abstract

The invention provides a non-load-balancing route switching method and device, relates to the communication field, and aims at realizing route switching by updating next-hop information of an ECMP resource when the amount of routes that need switching is large. The method comprises that route information is obtained, the route information is grouped according to main and standby next-hop information to generate grouped route information, a corresponding equivalent route ECMP resource is generated for each grouped route information, next-hop information of the ECMP resource is associated with main next-hop information of the grouped route information corresponding to the ECMP resource, and a route prefix of the ECMP resource is set as a route prefix of the grouped route information corresponding to the ECMP resource; and a path indicated by the next-hop information of the ECMP resource is detected, and when it is determined that the path indicated by the next-hop information of the ECMP resource has a fault, the next-hop information of the ECMP resource is associated with backup next-hop information of the grouped route information corresponding to the ECMP resource. The method and device are used for route switching.

Description

technical field [0001] The present invention relates to the communication field, in particular to a non-load balancing routing switching method and device. Background technique [0002] With the increasing importance of the network carrying services, the reliability requirements of the network in network communication are also getting higher and higher. In order to meet this requirement, when sending data through the network, if there are multiple paths between the source address and the destination address, the reliability can be improved by means of active and standby route backup, that is, the data is routed between the source address and the destination address In general, the data is routed to the main path for forwarding. When the main path fails, the data is routed to the backup path for forwarding. After the failure of the main path is eliminated, the data is routed to the The main path is sent.

Problems solved by technology

[0004] In the process of routing switching, the routing switching time is a very important indicator. Since the existing FRR mechanism and BFD mechanism consume less time, the switching time of the data layer often has a greater impact on the routing switching time.

Although the above routing switching method can update the routing prefix and its corresponding next hop information, it often takes a lot of time to delete the original routing prefix and the next hop information associated with the original routing prefix. When the next-hop information associated with the route prefix that needs to be updated is large, that is, when the amount of routes to be switched is large, the above-mentioned route switching method needs to update each new route prefix and associated next-hop information to achieve route switching. Purpose, resulting in a longer time consumed, which increases the overall routing switching time, reduces the efficiency of routing switching, and damages the user experience
