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
