摘要：

In this paper, we propose a new algorithm, Enhanced Differentiated Services Protection (EDSP), to satisfy the multiple services grades under multi-link failures in WDM optical networks. We consider three services grades, i.e., Diamond grade, Golden grade and Economy grade. For demand with Economy grade, EDSP only computes a primary path and does not consider protection. For demand with Golden grade, EDSP performs the shared protection policy. For demand with Diamond grade, EDSP uses the enhanced shared protection policy. Compared to conventional algorithm, EDSP has better resource utilization ratio, lower blocking probability and higher protection ability. Simulation results are shown to be promising.
