Illustrating a publish-subscribe Internet architecture

The Publish-Subscribe Internet Routing Paradigm (PSIRP) project aims at developing and evaluating an information-centric architecture for the future Internet. The ambition is to provide a new form of internetworking which will offer the desired functionality, flexibility, and performance, but will also support availability, security, and mobility, as well as innovative applications and new market opportunities. This paper illustrates the high level architecture developed in the PSIRP project, revealing its principles, core components, and basic operations through example usage scenarios. While the focus of this paper is specifically on the operations within the architecture, the revelation of the workings through our use cases can also be considered relevant more generally for publish-subscribe architectures.
