Abstract

The optical network architecture is undergoing a significant transformation to meet the world Internet traffic that demands ultra-high capacity and Terabit data rates. Network automation, elasticity and operational efficiency have evolved as a new challenge to deploy super wavelength in the transport networks. A flexible and scalable architecture that has evolved recently is Elastic Optical Networks. Bandwidth Variable Transponders with finer granularity and Flexible ROADM provide enormous bandwidth to the heterogeneous networks. Dynamic Routing, Modulation and Spectrum Assignment strategy is intended to optimize the resource utilization. A Cut based Fragmentation aware and Balanced Load Dynamic RMSA is proposed that optimize the transponder utilization and requested light paths. An appropriate defragmentation triggering policy is also investigated in this manuscript. Numerical results reveal that the proposed algorithm achieves better results in terms of bandwidth blocking probability, number of transponders per request and spectrum resource utilization compared to the benchmark EoN-RSA algorithms like k-Shortest Path Routing and Spectrum Assignment (k-SPRSA), Balanced Load RSA (BL-DRSA), Fragmentation Aware DRSA (FA-DRSA).
