Rate-based congestion control is effective and still simple for traffic management in ATM networks. One of its practical realization schemes is the enhanced proportional rate control algorithm (EPRCA) which has been proposed and adopted as a standard for traffic management scheme in the ATM Forum. An analysis for the EPRCA is provided for a network with homogeneous source traffic and a single bottleneck ATM link to investigate the dynamic behavior of the EPRCA. In addition to three types of switches suggested in the EPRCA, a prioritized switch is newly proposed. We exploit the dynamical behavior of the EPRCA and obtain the maximum queue length at the switch and the throughput by using the first-order fluid approximation method. Equations for parameter tuning for the EPRCA are also provided.
