摘要:

提出并证明了如果一个网络拓扑中的每个链路都可以配置两个仅边相交于该链路的p-cycles,那么该网络中的任意2个链路故障均能够得到完全保护。并提出了基于此准则的启发式算法,其仿真结果表明,在该配置准则中采用共享p-cycles能减少所需的保护容量。

关键词: 双链路故障, p-cycles静态配置, 保护

Abstract:

A static p-cycles deployment rule which every span is deployed by two p-cycles which are edge-joint just only with the span in optical network is proposed, so the dual span failures that can 100% survive is rigorously proven. The heuristic algorithms based on the rule are then suggested and the numerical results state that the p-cycles deployment with shared-p-cycles can decreases the protection capacity needed.

Key words: dual span failures, p-cycles deployment, protection
