Efficient changes and variability bandwidth allocation for VBR media streams

Abstract

Recently, the Internet bandwidth has increased rapidly. Currently available network traffic includes not only text but also graphics, such as JPEG and GIF images. Many multimedia applications are emerging, such as video on demand (VoD) and distance learning. These services involve complicated network connections between servers and clients. To simplify this system, we propose an effective and efficient traffic-smoothing algorithm, which is called ECVBA (Efficient Changes and Variability Bandwidth Allocation). This algorithm not only minimizes the peak rate of a stream but also increases the likelihood of successful variable bit-rate (VBR) stream transmission. The main benefit is that this algorithm can immediately release bandwidth to other demanding sites in the network.
