Performance Evaluation of Issues Related to Video Over Broadband Network

Multimedia applications such as video conferencing, video on demand, teleteaching etc are the major users of broadband networks. At the heart of this revolution is the digital compression of audio and video signals. Network supporting multimedia applications require certain performance guarantees from networks. Moreover when these applications are transmitted over satellite network, issues like limited bandwidth and throughput restrict them. Efficient allocation techniques are needed to provide guaranteed transfer. Various methods such as TCP and IP are available to transport multimedia applications. The TCP shows degradation in its performance in typical satellite environment due to slow-start, window size, and acknowledgment policy.
