一种在分布式系统中支持QoS的方法研究

摘要

服务质量(QoS)是分布式系统中最重要的因素之一，它直接影响着系统的质量和用户的满意度。本文提出了一种用UML这一通用建模工具支持分布式系统中QoS的方法，该方法对UML有所扩充，使之可以贯穿ISO RMODP的五种观点而支持QoS。%Quality of Service (QoS) is one of the most important factors in distributed system, which influence the quality of an application and the satisfaction of users directly. This paper provides a way of supporting QoS in distributed system by using of UML, which is an all-purpose tool for modeling. The way does some extensions to UML and makes it support QoS through the viewpoints of RM-ODP.
