Problems solved by technology

[0008] The present invention provides a method and device for balanced load sharing, to at least solve the problem in the related art that packet-by-packet strategy mode leads to packet out-of-sequence and jitter, and some paths are congested due to the flow-by-flow strategy mode. Some paths are idle, so bandwidth utilization cannot be guaranteed

Abstract

The invention provides a method and apparatus for balanced load sharing. The method includes: determining the load ratios between different interface types of each link, and grouping the links for load sharing according to the load ratios to obtain a load sharing member list of each link; writing index information of each link in each load sharing member list through address offset; obtaining a boundary value of each link after grouping by calculation through a preset rule, and writing the edge values in a load sharing policy table; and performing balanced load sharing on the interface bandwidth of each link according to the load sharing policy table and the index information. According to the method and apparatus, problems that in the related technology, situations of message disorder and jittering are serious by employing a packet-by-packet policy mode, and some paths are congested and some paths are idle by employing a stream-by-stream policy mode so that the bandwidth utilization rate cannot be guaranteed are solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for balanced load sharing. Background technique [0002] On network equipment nodes such as switches and routers, there are multiple links, and load balancing is performed on these links through corresponding policies and methods, which is load sharing. [0003] Load sharing needs to solve such a problem, that is, how to properly select a forwarding path when these network nodes have multiple paths to forward packets, so that the forwarding performance of the node can reach the optimum or meet certain forwarding requirements and How to reasonably and evenly distribute traffic to each link. [0004] In related technologies, there are mainly two strategy modes for processing load sharing on network device nodes. These two modes are flow-by-flow mode and packet-by-packet mode respectively. The so-called flow-by-flow means that all packets forwarded through t...
