Traffic Grooming for Clonal Selection Routing over Dynamically Wavelength-Routed Switched Networks

Traffic grooming is a promising technique to reduce the blocking probability in all-optical networks, in the context of the RWA problem (Routing and Wavelength Assignment). Routing with clonal selection algorithms is also an interesting approach for the same purpose. In order to create a robust mechanism to optimize the establishment of connections, this paper proposes a performance evaluation combining the aforementioned techniques and the traditional OSPF protocol. The analysis contemplates the variation of wavelength assignment heuristics in sparse networks with a highly dense traffic. The results show that the proposed approach obtained a blocking decrease of almost 60%.
