Preventing Bandwidth Abuse at the Router through Sending Rate Estimate-Based Active Queue Management

We propose a rigorous mathematical interpretation of a novel family of active queue management schemes, called sending rate estimate based queue management (SREQM) scheme, that aims to provide fair bandwidth allocation to all the flows in a router by estimating the flow sending rates, while maintaining only minimal per-flow state information. We propose an optimized implementation of SREQM, called fair sending rate estimate based queue management (FSREQM) scheme, and show through comparative simulation that FRESQM is the only scheme among those tested that successfully prevents bandwidth abuse while maintaining high link utilization.
