Hybrid Optimized Approaches for Routing and Resource Reservation Protocols in Optical Networks

We have proposed hybrid approaches to solve dynamic provisioning problems in fixed-grid and elastic optical networks (EON). The use the information from optimization models, which normally are used static problems, guide search for a good solution networking. presented three i.e., Route-Model, RouteRes-Model, RouteEON-Model. Route-Model computes routing is integrated with first-fit algorithm. RouteRes-Model routes set of wavelengths each end pair. Both models utilized wavelength assignment networks. Similarly, RouteEON-Model considers characteristics flexible information. This algorithm provisioning. solutions efficiently reduce blocking probability (BP) bandwidth BP EON compared shortest path first (SPF) alternate (k=2) routing. achieved high utilization other solutions. Finally, approximately equal number paths SPF However, routing, supported 43% 66% more traffic respectively while 36% same values BPs.
