R. Jain, S. Kalyanaraman, R. Viswanathan, R. Goyal, S. Fahmy, "ERICA: Explicit Rate Indication for Congestion Avoidance in ATM Networks," U.S. Patent No. 5,805,577, Issued September 8, 1998, Filed July 19, 1996.

Abstract

A congestion avoidance scheme for data traffic in ATM networks. The scheme achieves both efficiency and fairness, and exhibits a fast transient response. A congestion avoidance scheme for ATM networks is described which has its optimal operating point at 100% utilization and a fixed, non-zero queue delay. The scheme improves control of end-to-end delay and keeps link utilization of expensive links high despite idle periods in the input load.
