电子商务网站中的利润驱动请求优先级

客户的服务质量期望对于电子商务服务供应商来说是一项很艰巨的任务,在Web服务体验过多的情况下,将增加响应时间,遭到响应拒绝,使客户失望,减少对此服务的使用并减少收入.文章提出了服务器端的请求调度机制,RDRP（利润驱动的请求优先级）算法给了有可能带来更高利润的那些客户的Web请求较高的优先级.通过比较客户端信息到目前为止的请求,预测未来,使用这些预测对Web服务器进行优先分配.实验在JBoss Web应用服务器使用了RDRP技术的TPC-W基准测试应用程序,表明了RDRP能显著提高服务的利润,提供好的QoS给客户带来更多的利润.

The Reward-Driven Request Prioritity for e-Commerce Website

Meeting client Quality-of-Service（QoS） expectations proves to be a difficult task for the providers of e-Commerce services,especially when web servers experience overload conditions,which cause increased response times and request rejections,leading to user frustration,lowered usage of the service and reduced revenues.The article put forward a server-side request scheduling mechanism,Reward-Driven Request Priorititt（RDRP） algorithm gives higher execution prior-ity to client web sessions that are likely to bring more service profit（or any other application-specific reward）.By predicting future session structure by comparing its requests seen so far with aggregated information about recent client behavior,and using these predictions to preferen-tially allocate web server resources.Our experiments using the TPC-W benchmark application with an implementation of the RDRP techniques in the JBoss web application server show that RDRP can signif-icantly boost profit attained by the service,while providing better QoS to clients that bring more profit.
