Spectrum Resource Utilization and Security Enhancement in Multi-domain Elastic Optic Networks (MD-EON) Using Memetic Algorithm

Routing and Spectrum utilization is a challenging approach when optical signal is used in data transfer. The underlying bandwidth requirements in supporting the optical signal transfer and appropriate fragmentation are to be considered in routing and spectrum allocation. The problem lies with assigning a large bandwidth for a shorter duration of time or smaller bandwidth is provisioned for a larger duration. Thus the data transfer using memetic algorithm-elastic optical network (MA-EON) incorporates suggestion for crossing from one elastic optical network (EON) to different EON with its current spectrum utilization termed as global maximum. This flow within the EON is calculated as local refinement and is improved subsequently to obtain global refinement. MA-EON based finds better performance in terms of computational time in finding diverse routes and reduced blocking probability when compared to existing system used in this work.
