Quality-of-service (QoS)-enabled publish/subscribe (pub/sub) middleware provides powerful support for scalable data dissemination. It is hard, however, to maintain key quality of service properties (such as reliability and latency) in flexible environments (e.g., cloud computing infrastructure) and operating environments that change over time for distributed real-time and embedded (DRE) systems (such as disaster relief operations or power grids). Managing quality of service manually is often not feasible in these flexible and dynamic environments due to slow response times, the complexity of managing multiple interrelated quality of service settings, and the scale of the systems being managed. For certain domains, DRE systems must be able to reflect on the conditions of their environment and adapt accordingly in a bounded amount of time.

支持服务质量（QoS）的发布/订阅（pub/sub）中间件为可扩展的数据分发提供了强大的支持。然而，在灵活的环境（如云计算基础设施）和随时间变化的分布式实时和嵌入式（DRE）系统（如救灾行动或电网）的操作环境中，很难保持关键的服务质量属性（如可靠性和延迟）。由于响应时间慢、管理多个相互关联的服务质量设置的复杂性以及所管理系统的规模，在这些灵活和动态的环境中，手动管理服务质量通常是不可行的。对于某些领域，DRE系统必须能够反映其环境的条件，并在有限的时间内进行相应的调整。
