Quality of service of a rerouting algorithm using stochastic automata networks

New services are introduced in the broadband network such video or multimedia. These services have some quality of service constraint such as transit delay, and cell loss probability. To improve the quality of service, it is important to optimize the bandwidth utilization. In this study we focus on this problem, and our major contribution is to provide quality of service by the development of a new rerouting algorithm. All existing routing algorithms optimize at the time of call establishment. The originality of our contribution is to optimize routing before and after call establishment. To show the benefit of our algorithm we do a performance evaluation using a new technique called SAN (stochastic automata networks), which is adapted to our problem
