Parameter Tuning of Rate-Based Congestion Control Algorithms and Its Application to TCP Over ABR
Overview In this paper, the rate-based congestion control algorithm that has been standardized in the ATM Forum is evaluated. Its behavior is analyzed by utilizing a first-order fluid approximation to provide control parameter tuning. This paper obtains the maximum queue length at the switch and conditions for avoiding under-utilization. The results are then applied to TCP over ABR service class. More specifically, it evaluates the TCP-level performance through a simulation technique when TCP is applied to ABR service class with the rate-based congestion control. The paper first compares rate-based control of ABR service and EPD applied to UBR service, and show that rate based congestion control achieves better fairness and higher throughput in most circumstances.
