Layered multicast with TCP-friendly congestion control using active networks

The paper introduces a new scheme of receiver-driven layered multicast using active networks (RLM-AN). As most layered multicast schemes conduct an end-to-end congestion control mechanism, we propose a distributed TCP-friendly congestion control scheme. The multicast tree is regarded as a set of virtual links and TCP-friendly congestion control is performed on each virtual link. By introducing the congestion control mechanism in the active nodes inside the network, we obtain smoother and more TCP-friendly throughputs and quick response to congestion inside the network.
