Metastability of Fair Bandwidth Sharing Under Fluctuating Demand and Necessity of Flow Admission control
Vladimir V. Marbukh
A flow-level Markov model for fair bandwidth sharing with packet retransmissions under random flow arrivals/departures is proposed and discussed. Fluctuations in the numbers of flows in progress cause the network instability even under light load. The network can be stabilized with flow admission control at the cost of small flow rejection probability.
