PRE-CONFIGURATION BASED QOS ROUTING IN GMPLS-BASED OPTICAL NETWORKS

摘要：

Generalized Multi-Protocol Label Switching (GMPLS) based optical networks are viewed as a promising network infrastructure for the next generation network (NGN) development. By preconfiguring the resources of dynamic optical networks, we can reconstruct the physical topology, thus increase the number of direct routes between potentially heavily loaded physical node pairs and optimize the performance of the optical networks. This article presents the introduction to the optical network topology pre-configuration schemes and verifies the effectiveness of the QoS (Quality of Service) routing algorithm in the pre-configured topology of GMPLS-based optical networks. Simulation results show that the implementation of the QoS routing algorithm in the pre-configured GMPLS-based optical networks is instrumental in shortening the average establishing time of the control plane whilst maintaining the low block probability.
