On Multicast Routing with Traffic Grooming in Light-Trail Networks

In this paper, we proposed a dynamic multicast routing algorithm with traffic grooming consideration in light-trail networks, named Dynamic Light-Trail-based Multicast Routing algorithm (DLTMR) to efficiently find a good route for each multicast request. In the simulation, we use different network topologies and the various scenarios to verify that DLTMR can efficiently improve blocking performance in light-trail networks. On the other hand, we also verify that the light-trails are suitable to support the multi-granularity bandwidth demand and multicasting.
