基于内容的发布/订阅（CPS）是一种功能强大的范例，提供松耦合、事件驱动的消息传递服务。虽然通用CPS模型是众所周知的，但由于不同的应用程序需求，许多功能仍然是特定于实现的。这些需求中的许多都可以在将服务语义与系统机制分离的策略中捕获，但是在CPS上下文中目前不存在这样的策略框架。在本文中，我们提出了一种新的策略模型和框架CPS系统，受益于现有的CPS匹配算法的可扩展性和表现力。特别是，我们提供了一个参考实现和几个评估方案，演示了我们的方法如何轻松，动态地启用功能，如通知语义，元事件，安全分区和CPS防火墙。
Content-based Publish/Subscribe (CPS) is a powerful paradigm providing loosely-coupled, event-driven messaging services. Although the general CPS model is well-known, many features remain implementation specific because of different application requirements. Many of these requirements can be captured in policies that separate service semantics from system mechanisms, but no such policy framework currently exists in the CPS context. In this paper, we propose a novel policy model and framework for CPS systems that benefits from the scalability and expressiveness of existing CPS matching algorithms. In particular, we provide a reference implementation and several evaluation scenarios that demonstrate how our approach easily and dynamically enables features such as notification semantics, meta-events, security zoning, and CPS firewalls.
