Abstract

Abstract

This paper considers the survivability of WDM layer according to the client layers QoS requirements. A novel priority-based protection strategy is presented, and a QoS-based layered graph method is developed in the WDM optical transport network to reduced the blocking probability of the connection request. Based on them, a QoS-based RWA strategy in survivable WDM networks is proposed. Simulation results of the network performance in different dynamic traffic load are given. The results show that this algorithm can not only meet the different QoS requirements of the client layers service, but also utilize the finite networking resources efficiently with the reduced blocking probability.
