Multi-rate multi-casting is a generalization of singlerate multi-casting to prevent destinations with good connections from being limited by the capacity of bottleneck connections. While multi-rate multi-casting has been traditionally performed over fixed trees, advances in network coding theory have enabled higher throughput and have helped the user move beyond the restriction of tree structures for routing the multi-cast data. In this paper, the authors address the questions of optimal rate allocation and low-complexity network coding solutions to the problem of multi-rate multi-casting in general multi-hop networks.
