Transporting video over asynchronous transfer mode (ATM) networks has been an active area of research. The Variable Bit rate (VBR) service in ATM networks is primarily designed and used for real time application like compressed voice and video. Due to compressed video is inherently bursty, the bandwidth could not be efficiently utilized. The explicit rate (ER) flow control designed for Available Bit Rate (ABR) service provides a powerful control scheme to network congestion that it may be modified to VBR service for utilise the bandwidth and control the Quality of Service (QOS) of real time video or voice. In this paper, we present a simulation study of using modified ABR flow control algorithm Enhanced Proportional Rate Control Algorithm (EPRCA) to support compressed video over the ATM network, and compare its performance with VBR transmission. .
