针对当前边界网关协议(BGP)路由存在慢收敛会引起网络数据转发层服务质量下降问题,基于一个简化的BGP路由模型和核心网络拓扑结构,提出一个新的MRAI时钟设置方案。该方案需要根据已知网络条件先计算后设置。通过使用ssfnet仿真软件测试表明,与RFC1771中时钟抖动方案相比,该方案能够减少BGP平均网络收敛延时和更新消息交互数量。
Aiming at the problem that the quality of service in data forwarding plane may suffer heavily caused by slow convergence in Border Gateway Protocol(BGP) routing,based on a simplified BGP routing model and core network topology,this paper puts forward a new MRAI timer setup scheme.The scheme first calculates,then setup according to known network condition.Though simulation software ssfnet test,results show that compared with MRAI timer jitter setup in RFC1771,BGP convergence properties can be improved greatly by the proposed scheme.
