摘要：

We propose a novel shared sub-path protection algorithm (SSPP) to completely protect double-link failures in WDM mesh networks on the condition that all links are assumed to be share risk link group (SRLG) disjoint. SSPP firstly searches a primary path for each connection request and then segments the primary path into several equal-length sub-paths and searches two SRLG-disjoint backup paths for each sub-path. Under dynamic traffic with different load, the performances of SSPP are simulated. The results show that SSPP not only can completely protect double-link failures but also can make the tradeoffs between resource utilization (blocking ratio) and protection-switching time.
