摘要：

In this paper, we address the problem of differentiated reliable shared path protection algorithm under Shared-Risk-Link-Group (SRLG) constraint in survivable wavelength-division-multiplexing (WDM) optical networks. Rather than the conventional complete SRLG-disjoint shared path protection, we introduce a heuristic Partial SRLG-disjoint Shared Path Protection algorithm (Pd-SPP) based on the concept of SRLG conditional failure probability, to provide differentiated reliability protection. Our goal is to further improve the network resource utilization ratio under the DiR constraint. We adopt the ideas of partial SRLG-disjoint and the K-shortest paths algorithm such we can efficiently solve the "trap" problem. The experimental results show that our algorithm outperforms the complete SRLG-disjoint shared path protection in both blocking probability ratio and network resource utilization, the results are found to be promising.
