Dynamic bandwidth allocation for streaming MPEG coded video over ATM networks

The major driving force behind the emergence of broadband integrated networks Is traffic from video sources. For video sources the Moving Picture Experts Group (MPEG) compression scheme was proposed several years ago and it has become the defacto standard for video compression since then. However, even with the huge reduction of bits that MPEG compression provides, it does not smooth the video traffic. Indeed the MPEG compression algorithm guarantees that the MPEG stream will be bursty. A service, where an Asynchronous Transfer Mode (ATM) client requests and receives from an ATM server MPEG coded video sequences, is considered. An algorithm for streaming MPEG coded video delivery over ATM networks that dynamically allocates the transmission parameters is proposed. Simulation results with regard to this algorithm are presented. The results obtained show that the proposed dynamic allocation algorithm can provide an efficient solution for MPEG coded video transport with guaranteed Quality of Service (QoS) over ATM networks.
