A simulation study of TCP performance in ATM networks
This paper presents a simulation study of TCP performance over congested ATM local area networks. We simulated a variety of schemes for congestion control for ATM LANs, including a simple cell-drop, a credit-based flow control scheme that back-pressures individual VC`s, and two selective cell-drop schemes. Our simulation results for congested ATM LANs show the following: (1) TCP performance is poor under simple cell-drop, (2) the selective cell-drop schemes increase effective link utilization and result in higher TCP throughputs than the simple cell-drop scheme, and (3) the credit-based flow control scheme eliminates cell loss and achieves maximum performance and effective link utilization.
