Abstract

We study the transient network behavior of multicast and unicast connections in a differentiated-services capable Internet architecture under a major link failure. This is done using the MoMaRS 2.5 simulation tool that we have developed where we have implemented a multicast routing component and priority-based scheduling/routing to emulate a differentiated-services environment. In our simulation results, we consider the multicast workload to be of higher priority compared to unicast services. Our results show that the performance of the multicast routing protocol is essential in reducing the overall network utilization, thereby reducing the overall delay to all packets through efficient network utilization
