自适应Web QoS模型研究

Research in Model of Web QoS Control through Self-Tuning

描述了一种自适应Web QoS控制器模型。该模型通过对用户请求根据一定的请求分类策略进行分类以及动态监控和调整Web服务器配置参数的方法来达到要求QoS级别,使用启发式的禁忌搜索算法来求得QoS最优化配置,并通过仿真试验证实了使用此控制模型可有效保证网站的服务质量(QoS)。

In this paper,we describe a QoS controller model.The model enables web site operators to optimize the usage of their web sites by prioritizing among requests from different classes of users and dynamically monitoring and tuning web sites so that desired QoS levels are attained.Our approach uses heuristic tabu search algorithm to guide the search for the best combination of configuration parameters.The simulation results are demonstrated that the QoS controller model can provide better quality of service(QoS...
