Abstract :
A flow-level Markov model for fair bandwidth sharing with packet retransmissions and random flow arrivals/departures is proposed and discussed. Despite the model being unstable even under light exogenous load, a desirable metastable state may exist. The network can be stabilised with flow admission control at the cost of small flow blocking probability.
