摘要
在近似计算算法基础上,提出了一个最高优先级优先(Highest-Priority-First,HPF)算法。在HPF算法基础上,设计了一个Web内容自适应的PIK机制来代替传统Web服务机制,并通过修改Apache Web服务器软件,实现了一个基于Web内容树结构的内容自适应PIK机制。通过对PIK机制仿真实验表明,PIK机制提高了Web服务器对请求的响应质量和响应率,它为研究Web服务器区分服务和服务质量问题提供了一种新技术思路。
Based on algorithms of imprecise computation, a highest priority first algorithm of imprecise computation was presented. By using the HPF algorithm, a web content adaptation PIK mechanism to replace traditional web service mechanism was designed, Then, apache web server soRware to implement a content adaptation PIK mechanism based on web content tree structure was updated. From simulating experiment of PIK mechanism, it was explained that the PIK mechanism could improve the response quality of requests and response rate in web server. Finally, a new technological idea was proposed for researching of differentiated services and service quality in web server.
