摘要
当前的域间路由协议BGP全局敏感性极高且收敛慢。为了解决该问题,提出了基于区域的路由模型ZCR。在ZCR中,将同属于同一政治经济组织的AS划分为一个区域,在区域内采用连接向量路由协议,区域间以区域为单位部署路径向量协议。ZCR能够将网络事件控制在区域内,在支持路由策略的同时降低网络的全局敏感性,提高网络的收敛速度。并且ZCR可以在Internet中递增部署,以便逐步对当前网络进行升级改造。AS级别的实验结果显示了ZCR的有效性。
As the defacto interdomain routing protocol, BGP has high sensitivity and is slow to reach convergence. To improve the controllability of routing, a zone-based controllable routing model（ZCR） was proposed in this paper. In ZCR, ASes needed to be controlled can be organized to a zone where the link vector muting protocol is employed inside the zone and path vector protocol is taken between zones. ZCR can support routing policies, improve the convergence speed and reduce the load of routing. Moreover, ZCR can be deployed incrementally in the network. Experiment results show that ZCR is effective.
