Quality Incentive Assisted Congestion Control for Receiver-Driven Multicast

The potential problem of oversubscribing receivers in receiver-driven multicast is addressed. We present a framework based on harmonizing the erasure-resilience properties of video with existing congestion control algorithms. The result offers subscription alternatives for receivers in which a penalty in terms of visual quality will be experienced by oversubscribing receivers. Thus, we provide an incentive for performing proper congestion control. The presented framework is independent of specific congestion control algorithms. Simulation results show the intended performance.
