Packet loss probability for DiffServ over heterogeneous MPLS multicast networks: a simulation study

In this paper, we present a fair share policy (FSP) that utilizes Differentiated Services to solve the problems of QoS and congestion control when reliable FEC/ARQ multicast is adopted. Simulation programs are used to evaluate the fair share policy. The results should provide insights into the comparisons between homogeneous IP multicast networks, homogeneous MPLS multicast networks and heterogeneous MPLS multicast networks using the same FSP when DiffServ is adopted and when reliable FEC/ARQ multicast is considered. This comparison is based on the residual packet loss probability.
