摘　　要：针对当前大多数光网络恢复机制仅某一个端节点启动恢复的缺陷,为进一步减少恢复时间,提出一种基于端节点启动的双向快速恢复机制。仿真证明,该机制在恢复时间上表现出优越的性能,其最好时甚至能提高恢复速度80%以上,从而实现光网络的快速恢复。To further reduce the restoration time, a novel bidirectional fast restoration mechanism based on end-nodes initiated is proposed, which focuses on the defect that is only single end-node initiating the restoration in the most of the current restoration mechanisms. Through computer simulation, it is proved that the proposed mechanism shows excellent performance on restoration time. In its best situation, it can improve the restoration speed by 80%, realizing rapid restoration in the optical network.
