基于RSVP-TE的网状IPO全光网络的快速故障恢复算法

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．文中还给出了算法的延时的评估公式和仿真计算的结果．

RSVP-TE Based Fast Fault Restoration Scheme for Meshed All-optical Networks

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.
