现有的发布/订阅系统有几个缺点，例如依赖可靠的代理的固定基础设施，或者他们的订阅语言缺乏表现力。最重要的是，基于内容对消息进行路由的挑战性任务仍然是一项复杂而耗时的操作，并且通常提供的结果仅略好于简单的广播。在本文中，我们提出了一种新的发布/订阅方法，该方法旨在专门解决这些问题。生产者和消费者被组织在对等网络中，该网络在对等网络到达、离开或失败时进行自我适应。我们的发布/订阅系统具有极其简单和高效的路由过程，并在路由和对等管理开销方面针对大量消费者群体具有出色的可扩展性。
Existing publish/subscribe systems suffer from several drawbacks, such as the reliance on a fixed infrastructure of reliable brokers, or the lack of expressiveness of their subscription language. Most importantly, the challenging task of routing messages based on their content remains a complex and time-consuming operation, and often provides results that are just barely better than a simple broadcast.In this paper, we present a novel approach to publish/subscribe that was designed to specifically address these issues. The producers and consumers are organized in a peer-to-peer network that self-adapts upon peer arrival, departure, or failure. Our publish/subscribe system features an extremely simple and efficient routing process and excellent scalability to large consumer populations, both in terms of routing and peer management overhead.
