The Flushing Mechanism for MBAC in Flow-Aware Networks

Abstract

The paper describes the flushing mechanism as an enhancement proposed for the measurement based admission control (MBAC) block in flow-aware networks (FAN). It focuses on periodical cleaning of the contents of protected flow list (PFL) in the congestion state. The mechanism is discussed and performance evaluation results are presented. The paper shows the motivation for FAN networks and presents simulation results evaluating the acceptance time of a new streaming flow in the congested link and bandwidth allocation for elastic flows. A new concept of the flushing mechanism in FAN networks, which improves network performance and servicing of streaming flows, is proposed.
