Distributed Traffic Grooming Technique for dynamic traffic in all Optical WDM Networks

ABSTRACT Ample growth in network traffic users has caused sporadic nature of traffic load.The traffic load has a direct effect on the throughput of the network. Reducing the block probability, improving the throughput and Quality of Service is of major concern. In this paper, Distributed dynamic Traffic Grooming RWA (DTG) techniqueis proposed for selecting the optimal path based on the unpredictable traffic load conditions. Traffic is classified into classes based on priority. Paths are selected on the basis of blocking probability.A single failure can cause a tremendous loss of data. Survivability is guaranteed by preconfiguring a backup path. The simulation results show a reduction in blocking probability and improvement in throughput which improves the QoS of the optical network.
