ECN-capable TCP-friendly layered multicast mul-timedia delivery combines explicit congestion notifica-tion (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 proto-cols (TFRC, 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 con-gestion 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 mul-ticast multimedia delivery in ns-2 environment is dis-cussed.
