A novel scheme of transporting pre-stored MPEG video in ATM networks

This paper focuses on the optimization of network bandwidth allocation and buffer dimensioning in the transporting of pre-stored MPEG video data from a source to a playback destination. This is one of the most important issues to support video-on-demand service. This paper provides a novel scheme in the dynamic allocation of bandwidth to segments of video using ABR mode to ensure that the playback buffer neither underflows nor overflows. The proposed scheme is tested with real-life MPEG video traces. The obtained results have shown its significant performance improvement on the required capacity of playback buffer, the start-up playback delay, and the network multiplexing gain.
