Efficient Scheduling Algorithms on Bandwidth Reservation Service of Internet Using Metaheuristics

Network services that dynamically allocate bandwidth resources, such as QoS and layer-1 bandwidth-on-demand(BoD), are increasingly required to advanced Internet backbones, such as science information networks (SINET) in Japan. In this paper, we propose scheduling algorithms for BoD service which allocate parts of full bandwidth dedicated to specific users according to their requests in advanced Internet backbones. The scheduling algorithms maximize the number of accepted requests, fairness, or the total bandwidth in BoD. Simulation results show that the proposed algorithms achieve high utilization of network resources and user´s fairness, compared with a simple random-based algorithm.
