A CONGESTION CONTROL ALGORITHM FOR MULTIPOINT-TO-POINT ABR SERVICE IN ATM NETWORKS

Study of congestion control for multipoint-to-point connections are still in early phases.So far the related works focus on extending point-to-point algorithms to multipoint-to-point environment,which can implement source-based fairness easily.But source-based fairness means no fairness between VCs at all.So VC/source based fairness may be the better choice.In this paper,issues about designing VC/source based congestion control algorithms are deeply studied.A set of design principles and a congestion control algorithm are proposed in the first time.Simulation results show that this algorithm can implement VC/source based fairness,converge fast to steady state,and have high link utilization.
