| Abstract: | With the widespread uses of the streaming technology over Internet, proxy caching has been introduced to the area of media streaming from that of Web content distribution. Due to some distinct characteristics of streaming media object, novel caching techniques for streaming media are required to replace the traditional Web caching techniques. The critical issues and challenges of proxy caching strategies for streaming media are reviewed in this paper. We survey, classify, and compare the state-of-art various proxy caching solutions for streaming media. Finally, the fu ture research issues in this field are outlined. |
