Traffic grooming and spectrum overlap in FIPP p-cycle for protection of elastic optical networks

Elastic optical networks has emerged as a solution for dealing with the diversity of bandwidth demands of network applications. However, networks are not sufficiently resilient, survivable, highly available and dependable, therefore, protection techniques have been developed to cope with failures. Among these techniques, p-cycle is a very attractive once since it provides ring-like speed of restoration in mesh topologies. This paper presents a new algorithms to provide path protection using p-cycle path, traffic grooming and overlap spectrum in elastic optical networks. The proposed algorithm is compared to others existing in the literature. Results indicate that the our algorithm can provide up to 40% less blocking when compared to existing other algorithms.
