Traffic grooming algorithm in GMPLS Architecture combined with RWA utilizing dynamic fiber state information

Abstract

Telecommunication networks have had massive transitions from circuit switched networks to pure optical networks. Pure optical wavelength routed networks are the future of backbone networks. These networks incorporate technologies like dense wavelength division multiplexing and generalized multiprotocol labeled switching for its control plane. To optimize these networks, efficient traffic engineering, dynamic routing and wavelength assignment techniques need to be incorporated to improve connection blocking probabilities. The proposed traffic grooming algorithm reduces the blocking probability of the network, thus resulting in substantial improvement in network resource utilization.
