Video over TCP with receiver-based delay control

Unicasting video streams over TCP connections is a challenging problem because video sources cannot normally adapt to delay and throughput variations of TCP connections. This paper points out a direction on how TCP can be modified such that TCP connections can carry hierarchically-encoded layered video streams well, while being friendly to other competing flows. The method is called Receiver-based Delay Control (RDC). Under RDC, a TCP connection can slow down its transmission rate to avoid congestion by delaying ACK packet generation at the TCP receiver based on notifications from routers. The paper presents the principle behind RDC, argue that it is TCP-friendly, describe an implementation that uses 1-bit congestion notification from routers, and give our simulation results.
