Abstract:
Elasticity plays a role in the next generation of optical networks. The spectrum helps to fit the optical path provision of user demands and services. A substantial part of the spectrum is not much useful, and the optical path guard bands are used. It is possible to use the traffic grooming technique to improve resource usage. Using the guard bands can minimize spectrum usage as the grooming techniques permit the development of optical tunnels with many connections. The major issue in elastic optical networks is the routing spectrum allocation that helps to solve the grooming problems. It is difficult to work in large-size instances. Optical layer for grooming capability for grooming. To design the EON, we use a metaheuristic approach to solve the traffic grooming issues with static traffic demands. The advocated design in this paper helps to reduce the spectrum use and also serves the traffic demands. Finally, while we compare the non-grooming case, we achieved significant spectrum changes.
