New emerging technologies like Multimedia applications require timely delivery of information as compared to reliability. The most widely used protocols over transport layer are Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). Both of these have some drawbacks while using in real time applications. TCP increases delay in transfer of data but achieving reliable transfer of data...
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 (TFRC, TFMCC, WEBRC), which use TCP throughput the equation, our system assures TCP-friendliness...
This paper presents the performance evaluation of a multi-rate multicast protocol named adaptive smooth simulcast protocol (ASSP) for simulcast video transmission. ASSP implements a single rate TCP-friendly protocol as the underlying congestion control mechanism for each simulcast stream. ASSP is built on top of the RTP/RTCP protocol and exploits the RTCP sender and receiver reports for the dissemination...
