A proxy caching system based on multimedia streaming service over the internet

Abstract

As real-time streaming media is becoming a significant proportion of network traffic, interest in exploring caching system for streaming media objects has increased. However, existing techniques for caching Web objects are not appropriate for the multimedia streaming service. In this paper, we focus on the proxy caching problem specifically for multimedia streaming objects. A prototype design and implementation of a proxy caching system - HUSTProxy is proposed. The main contribution of HUSTProxy is its ability of partial video caching, prefix caching, and sending rate control. These techniques are implemented in our system and are detailed discussed in this paper. By validate our implementation, the experimental results show that the partial video caching can contribute to economize disk cache space and the rate control mechanism can contribute to reduce service startup latency as expected. © Springer-Verlag Berlin Heidelberg 2004.
