Paper Abstract

It has been widely recognized that survivability is of great importance in survivable mesh WDM networks. Among various survivable schemes proposed in the literature, segment shared protection is reported to have the best performance in terms of making trade offs between spare capacity utilization and restoration time. This paper proposes a novel technique, called backup segment backup cost adjusting (BSBCA), to further reduce the spare capacity consumed for shared segment protection. To guarantee the BSBCA technique can be used in real networks, we further propose a novel approach to select appropriately the backup segment whose backup cost will be adjusted. Simulation results demonstrate the good performance of the BSBCA technique.
