摘要
随着流媒体技术在互联网上的广泛应用,原有用于加速 Web 内容分发的代理缓存技术也被应用于流媒体内容分发领域。然而,由于流媒体对象的一些独特特点,需要在传统 Web 缓存技术的基础上提出适用于流媒体对象的缓存技术。本文分析了基于代理缓存的流媒体分发中的关键问题和技术挑战,对现有的各种流媒体缓存方案进行了综述、分类和比较,最后对流媒体代理缓存的未来发展方向进行了展望。
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.
