Abstract

The invention discloses a message transmission method and device based on equivalent multipath ECMP. The method comprises the following steps: receiving a message, and obtaining a hash value of the message and a base address of a corresponding outlet package table; obtaining the number of transmission links, and modeling the hash value and the number of the transmission links to obtain a module value; obtaining package information from the outlet package table according to the base address of the outlet package table and the module value; and packaging the message according to the package information, and sending the message, in order to at least solve the problem that the transmission links in the prior art cannot uniformly share message transmission.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a message transmission method and device based on ECMP (EqualCostMulti-Path, Equal Cost Multi-Path). Background technique [0002] ECMP (EqualCostMulti-Path, Equal Cost Multi-Path) is a technology that improves the shortest path-based interior gateway routing protocol in IP networks. In the traditional shortest path algorithm, if two or more shortest paths exist at the same time, the algorithm will choose the optimal one. However, ECMP has been improved, and traffic is distributed among multiple equal-cost paths. After ECMP is deployed in an MPLS (Multi-protocol Label Switching, multi-protocol label switching) network, it is necessary to meet the protection switching requirements of the carrier level when a link fails. [0003] In related technologies, figure 1 It is a flow chart of a method for ECMP-based message transmission according to related technologies, such as figu...
