摘要
网状全光 IPO(IP over Optical)网的故障恢复是一个研究的热点 ,主要研究点都是基于保护通路的计算算法和波长分配算法等 ,但是缺乏一种快速的恢复建立的机制 .本文提出了一种采用基于扩展了的 RSVP- TE协议的快速的故障恢复机制 ,在大大节约网络带宽的同时又能获得很好的保护性能 .
Mesh restoration is a new but hot research field, and most of the recent research work focuses on protection routing and wavelength assignment computation. But there is a need for a scheme to do fast restoration establishment. In this paper, we provide a fast scheme based on shared mesh restoration path using GMPLS/RSVP TE as the signaling, which can save a lot of bandwidth. In this scheme, we introduced a small modification to RSVP TE protocol as to do parallel resource reservation to gain fast restoration. The performance of this scheme is evaluated at last.
