Abstract

A clock synchronization method provided by the present invention is applied to a cluster routing system, the cluster routing system comprises a main center frame router and two business frame routers, and the clock synchronization method comprises the following steps of using the main center frame router to set a clock source according to the configuration data inputted by users, wherein the clock source is the main center frame router or the business frame router; using the main center frame router to obtain the synchronous clock information preset in the clock source, wherein the synchronous clock information comprises the frequency synchronization information and the phase synchronization information; using the main center frame router to sent the synchronous clock information to the corresponding router according to the type of the clock source, so that the routers are in clock synchronization. The present invention also discloses the cluster routing system. According to the present invention, the working stability of the cluster routing system can be improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a clock synchronization method and a cluster routing system. Background technique [0002] Router cluster technology is to bridge two or more ordinary routers through one or more special center connection routers, so that these ordinary routers can cooperate with each other and process in parallel, just like a router is working, so as to realize bandwidth upgrade and Increased processing power. In a cluster, common routers are called service frame routers, and center connection routers are called center frame routers. [0003] In digital communication systems, data is transmitted in the form of data streams. When these data streams are transmitted between digital switching devices, their rates must be completely consistent to ensure the accuracy of data transmission. It can be understood that, in order to enable the routers in the cluster to work together, it is necessar...
