分布式路由器系统数据一致性维护方法

Maintenance on Consistency of System Data in Distributed Router

目前的高性能路由器多采用分布式体系结构,它能够大大提高报文的转发速率,但是也为路由器系统数据在主控处理单元和各个分布式接口处理单元上的一致性维护带来了困难。文章通过介绍分布式路由器系统数据维护的流程及特点,从三个方面分析造成数据不一致的原因,并分别提出解决方法,最终实现分布式路由器系统数据的一致性维护方法。

Recently, distributed architecture is adopted by most high performance router. It can greatly raise the rate of forwarding packets. However, it also causes some difficulties in data consistency maintenance between the main control unit and the distributed interface processing unit. By introducing the process and characteristics of system data maintenance in distributed router, this paper analyzes three reasons which lead to inconsistent data, proposes solutions respectively, and finally describes the realization of maintenance on consistency of system data in distributed router.
