辽宁联通互联网网络扁平化路由策略研究及实施

辽宁联通网络扁平化建设向层次化和精简化转变,形成一个互操作的、融合的网络结构,各城域网直接与骨干网互连,从而降低设备跳数,减少网络瓶颈和网络延时,在路由策略方面,城域网核心路由器与省网核心路由器建立BGP邻居关系时引入AS过滤策略,城域网不接收来自其他城域网的路由通告,城域网互访流量通过骨干落地路由器转发,省内访问流量通过城域网核心路由器至省网核心路由器的电路实现,统一全省的路由策略。在扁平化后网络应急预案保障中,通过MPLS转发技术,对城域网到IDC拥塞的链路进行流量调整,保障用户上网质量。本文介绍了其路由策略及实施。

Liaoning Unicom Internet Network Flattening Route Strategy Research and Implementation

The Liaoning Unicom flattening construction transforms to the hierarchization and the fine simplification,forms an interoperability,fusion network architecture.Various metropolitan area networks directly connects with backbone network interconnection,thus reduces the equipment to jump the number,the network bottleneck and network latency.When the route strategy aspect metropolitan area network core router and the province net core router establishes the BGP neighbourship,it introduces AS filtration strategy...
