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2个仅边相交于该链路的p-cycles,则该网络中的任意2个链路故障均能得到完全保护.同时提出了基于此准则的启发式算法,并进行了仿真。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.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.
