Abstract :
We study the stability and performance of a system involving several TCP connections passing through a tandem of RED controlled queues each of which has an incoming exogenous stream. The exogenous stream, which represents the superposition of all incoming UDP connections into a queue, has been modeled as an MMPP stream. We consider both the TCP Tahoe and the TCP Reno versions. We provide the conditions for stability of the system and closed form expressions for the throughput of the TCP connections and the mean sojourn times of the TCP and the exogenous streams. A decomposition approach has been used to simplify computations. These results have implications for bandwidth reservation and providing QoS in the Internet
