ABSTRACT
Traffic management and congestion control are major issues in Asynchronous Transfer Mode(ATM) networks.
Congestion arises when traffic in the network is more than offered load. The primary function of congestion
control is to ensure good throughput and low delay performance while maintaining a fair allocation of network
resources to users. In this paper, Enhanced Proportional Rate based Congestion Avoidance (EPRCA) scheme
proposed by ATM forum has been considered. But this scheme has limitation of higher cell drop problem for the
bursty traffic. Improvements to EPRCA scheme have been proposed to reduce cell drop problem and results of
improved EPRCA schemes were analyzed with basic EPRCA scheme.
