| Abstract | The Web has become an integral and essential part of modern life, and web-caches have become an integral part of the Web. Web-caching technology was invented to alleviate the performance burden of the ever-increasing web traffic on the Internet. This dissertation discusses contributions I have made to web-caching over more than a decade, beginning in 1994 as a team member of the Harvest Cache project at the University of Southern California.; I discuss fundamental web-caching technologies that are the fruits of the Harvest Cache project including Hierarchical Web-caching, Transparent Web-caching, and Web-acceleration. I also discuss commercial web-caching technologies derived from Harvest Cache, such as Network Appliance's NetCache. As part of the research involved in this dissertation, I conducted a web-cache performance study that included both throughput and web-cache effectiveness in real-world deployments. I found that a proxy web-cache average hit rate is 35%, an average bandwidth saving is 15%, and the average response time improvement factor is 1.5. The primary cause of poor performance is simple: up to half of Web objects are not cacheable. On the other hand, I found that a web-accelerator web-cache achieves much higher performance. A web-accelerator average hit rate is 80%, an average bandwidth saving is 75%, and the average response time improvement factor is 1.5 - 2.3. |
