Abstract:
To find a set of anycast routing paths satisfying both the bandwidth requirement and the shortest time delay,a quality of service anycast routing algorithm with bandwidth and time delay constraints is researched.A polynomial time approximation scheme suitable for the nondeterministic polynomial problem is proposed to solve the problems of bandwidth and time delay constraints.Simulation results show that:while the network scale or bandwidth requirement grows,the increase of time delay of this algorithm is little so that it is scalable and robust.Compared with heuristic algorithms such as the shortest path first anycast routing algorithm and the maximum bandwidth path first anycast algorithm,this algorithm has better performance advantages in bandwidth-limited large-size networks.
