Abstract

Under the condition of a single link failure, a routing algorithm with differentiated reliability requirements based on hierarchy model (DRRH) is proposed by analyzing the optimal routing mechanism which satisfies the reliability requirements. Simulation results and analysis show that the DRRH algorithm is able to solve the routing problem based on the reliability constraint and has a lower average cost than the SPPA algorithm. It means that the DRRH algorithm can meet the reliability requirements of routing connections with fewer resources and improve the network resources efficiency utilization as a restore routing scheme in complex mesh optical network.
