摘要:

通过对实际业务的监测, 总结了万维网业务的协议和流程, 提出了1组针对web业务的服务质量(QoS)指标,这些都是基于传输层和应用层的端到端QoS指标, 既能直接反映用户访问网站时的质量感知, 又能从技术角度说明造成用户感知的原因,以及各指标的概念、算法及与现有QoS指标和用户感知之间的关系. 在实际网络环境下, 通过对这组指标的主动监测实验, 对用户感知的web业务QoS进行了分析. 实验证明,这组指标能更好地反映用户感知的web业务QoS.

Abstract:

World wide web traffic protocols and details are analyzed with measurements. A group of quality of service (QoS) parameters of web traffic are proposed. These parameters focus on highlayer and endtoend QoS. They can reflect users' feelings when visiting websites and can also give technical details on reasons of such feelings. Concept and algorithm of each parameter are described. The relationships among each parameter, existing parameters and userfeelings are analyzed. Active measurements on practical web traffic are performed during recording these parameters. The useraware web QoS is analyzed correspondingly. Measurement shows that given parameters can reflect useraware web QoS better than existing ones.
