Abstract

We consider a system where streaming and/or real time applications, using the UDP protocol pass through a bottleneck router. Several persistent and non persistent TCP connections may also be passing through that router. Using the rate control at the UDP sources and choosing the RED parameters appropriately, we obtain pre-specified delays, little delay jitter, no packet loss, 100% channel efficiency, pre-specified throughput for the TCP and UDP streams and little rate fluctuation. We verify our control scheme by extensive simulations. Results are extended to a tandem of queues.
