Abstract

The method comprises: pre-determining the traffic forwarding ratio of output interface corresponding to different link; according to the traffic forwarding ratio, outputting all messages via the corresponding output interface; due to different traffic forwarding ratios of output interfaces corresponding to different links, the different links can load different traffics while realizing the load balance and link protection such that the links with different physical properties can selected to be as equivalent chain.

Description

technical field

[0001] The invention relates to routing technology, in particular to a multi-link-based message forwarding method and a multi-link-based message forwarding device. Background technique

[0002] Load Sharing and Link Backup are two important technologies in traffic forwarding, which can respectively realize resource sharing and link protection in the process of traffic forwarding.

[0003] Taking two edge routing devices as an example, it is assumed that the two edge routing devices are routing device A and routing device B respectively, and routing device A and routing device B are connected by at least two links. According to the following method, set the consumption (Cost) value or multi-exit distinguishing symbol (MED) value corresponding to at least two links in routing device A and routing device B, respectively, to realize load sharing and link backup:

[0004] If the Cost value or MED value corresponding to each link is set to a different value, all p...
