ECN-capable TCP-friendly layered multicast multimedia delivery combines explicit congestion notification (ECN) with the TCP-friendly layered multicast scheme. TCP-Friendliness denotes that receiver-driven architecture behaves under congestion like the TCP protocol. Unlike well-known TCP-friendly protocols (TTRC, TFMCC, WEBRC), which use TCP throughput the equation, our system assures TCP-friendliness by emulation. The Receiver emulates TCP congestion control mechanism working with ECN congestion notification. Decisions about changing group membership and, as a result, about changing effective transmission rate, are taken based on TCP emulation. In the paper, a simulation model of ECN-capable multicast multimedia delivery in ns-2 environment is discussed.
