Abstract
The transition from wavelength routed optical networks to the elastic optical network was evident because of the limitations of the wavelength division multiplexing (or WDM) optical networks. The elastic optical network is superior to the WDM optical networks because of its flexible spectral allocation and finer grid granularity. Since all the optical networks consists of a set of optical fibers which are vulnerable to fiber cut or failure, there should be some mechanism to protect the networks from failure. In this paper, a segment based protection scheme is integrated with a traffic grooming policy that could optimize the network resources as well as provide protection to the network optical fibers. The comparative study of the proposed grooming and protection based approach with a non grooming segment based approach reveal that the grooming based approach has better spectrum utilization and also it is computed in less CPU time than non grooming approach for static multicast traffic demands.
