%X In this paper, a Dynamic Shared-Path Protection (DSPP) algorithm is proposed for double-link failures in WDM mesh networks on the condition that all links are assumed to be Share Risk Link Group (SRLG) disjoint. DSPP can dynamically adjust the link-cost according to the current state of the network, and it searches a minimum cost primary path and two minimum cost and SRLG-disjoint backup paths for each connection request. Under dynamic traffic with different load, the performances of DSPP have been investigated via simulations. The results show that DSPP not only can completely protect double-link failures but also can make the tradeoffs between the resource utilization ratio, blocking ratio, and protection-switching time.
