【摘要】：环回和源路由是多协议标签交换-传输应用(multi-protocol label switching transport profile,MPLS-TP)网络环保护的2种基本方式,融合它们有利于减少丢包和降低数据时延。针对目前融合二者的方法在控制分组传输路径和倒换时延方面存在冗余的问题,提出一种新的环保护方法—高效的环回和源路由网络环保护(efficient wrapping and steering,EWAS),通过精简控制分组传输路径消除路径冗余,降低控制分组传送开销和倒换时延,并使中间节点自动倒换数据传送通路以减少数据分组转发次数。理论分析验证了新方法的有效性,仿真结果显示,与环回、源路由和环回和源路由网络环保护(wrapping and steering,WAS)方法相比,EWAS的控制开销和倒换时延分别降低20.55%和15.18%以上。
[Abstract]:Loop back and source routing is a multi protocol label switching transmission (multi-protocol label switching transport application profile, MPLS-TP) 2 basic ways of network protection ring, their integration is conducive to reducing the loss and reduces the time delay of the data. In view of the current integration of the two methods in terms of packet transmission path and switching delay control redundancy problem is proposed a new method of efficient protection ring loop and source routing network (efficient wrapping and steering ring protection, EWAS), by streamlining the control packet transmission path to eliminate path redundancy, reduce control overhead and packet switching delay, and the intermediate node automatic switching data transfer channel to reduce data packet forwarding number theory. The analysis shows the effectiveness of the proposed method, the simulation results show that with the loopback, source routing and loopback and source routing network ring protection (wrapping and steering, WAS Compared with the method, the control overhead and the change delay of EWAS are reduced by 20.55% and over 15.18% respectively.
