摘 要: 服务质量QoS管理是满足分布式环境中端到端QoS需求的关键,而中间件是一种分布式系统中的主要交互平台。首先对中间件和QoS的相关概念进行介绍,在分析传统QoS管理模型的基础上,提出一种基于消息中间件(MOM)的QoS管理模型,重点分析多维QoS在该模型中的应用,最后结合一个实例说明多维QoS在实际系统中的应用。 QoS management is the key to meet end-to-end QoS requirements in distributed environment, and middleware is a main interactive platform in distributed system. First, the related conception of middleware and QoS is introduced, a QoS management model based on message-oriented middleware is presented on the basis of analyzing traditional QoS management model. The application of multi-dimension QoS in this model is discussed in detail. At last, a case is used to explain how multi-dimension QoS is applied in a real system.
