发布／订阅中间件为分布式系统数据分发提供有力支持，同时提供了多种服务质量（quality of service ，QoS）供用户选择。然而在动态环境中，发布／订阅中间件不能根据环境变化自动调整QoS机制来满足用户的需求。为此，开展了发布／订阅中间件自适应QoS研究，包括集成发布／订阅中间件、可调整传输协议框架以及监督学习技术，以实现 QoS 自适应调整，最后对发布／订阅中间件自适应QoS进行了定性评估。

The publish/subscribe middleware provides powerful support for data dissemination in distributed systems ,and provides quality of service (QoS) for users to choose .However ,the QoS mechanisms used by the middleware cannot adaptively change to ensure certain QoS properties meet the needs of users in the dynamic environment .In order to solve this problem ,this paper describes the study of adaptive QoS of publish/subscribe middleware . It integrates the publish/subscribe middleware with adaptive transport protocol framework and supervised learning to adaptively adjust the QoS mechanisms ,and qualitatively evaluated the performance of the adaptive QoS .
