Abstract :
A dynamic FEC (DFEC) scheme for VBR video in ATM networks is proposed to maximise the utilisation of network resources while keeping the cell loss rate and video quality degradation at minimum levels. The proposed scheme is based on identifying an operating error control state that can match the actual fluctuations in video source and network utilisation within a specified control interval. A source classifier, network monitor, and system controller are designed to perform the rules for identifying the operating error control states. We demonstrate the effectiveness of the proposed scheme by comparing its performance with three existing schemes in terms of loss rates, throughput, and quality degradation
