【摘要】 近年来,由于Web缓存技术对缓解因特网上热点现象的有效性,它已迅速得到了研究人员和业界的关注。适应性Web缓存(adaptive Web caching)由于能够根据用户的不同访问模式,自适应地调整热点数据在缓存系统中的分布,自动均衡整个缓存系统的负载,因而成为了缓存技术研究的一个新的热点。本文介绍了适应性Web缓存领域的研究状况,详细分析了基于组播和基于单播这两种主要的适应性缓存技术。最后,指出了适应性Web缓存研究存在的问题和值得进一步改进的方向。更多还原

【Abstract】 Recently, in the face of rapid growth of the Internet, Web caching has emerged as a effective way to reduce network traffic and latency. Adaptive Web caching is a new subfield of Web caching, which can adapt to different user access patterns, self-organize system structure and distribution of popular data, hence reducing overall network load. In this paper, we firstly overview the recent research status in adaptive Web caching. Then we analyze two kinds of adaptive Web caching systems, one of witch uses multicast while the other uses unicast. At last we discuss some is- sues in the research of adaptive Web caching and the future work.更多还原
