Prototype Implementation of a Proxy Caching System for Streaming Media Objects

Existing techniques for caching Web objects are not appropriate for the multimedia streaming service. In this paper, the authors 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, sending rate control and providing a more rational prefix caching size determination. These techniques are implemented in our design and are discussed in detail in this paper.
