Providing guaranteed deterministic performance service to multimedia applications on WDM optical networks

A major challenge in design of high-speed networks is to provide guaranteed quality of service for multimedia applications. We propose an admission control policy, a traffic regulator and a scheduling algorithm for the single-hop passive star coupled WDM optical networks. All of them are combined to ensure guaranteed deterministic performance service to multimedia applications. We set up an analytical model to evaluate the deterministic bounded message delay in the specified network based on the max-plus algebra. We conduct a trace-driven simulation with real MPEG traffic. We model MPEG traffic with the parameters of the real MPEG traffic and use them in discrete event simulations. Both simulation results show that our systematic scheme and our analysis are feasible to multimedia applications
