“…Publish/subscribe (pub/sub) is a powerful messaging paradigm that maintains a clean decoupling of data sources and sinks [3,4,5,8,14,24,31,34]. Interoperating through simple publish and subscribe invocations is especially useful for the development of large, distributed, loosely coupled systems.…”

Abstract. This paper develops content-based publish/subscribe algorithms to support general overlay topologies, as opposed to traditional acyclic or tree-based topologies. Among other benefits, publication routes can adapt to dynamic conditions by choosing among alternate routing paths, and composite events can be detected at optimal points in the network. The algorithms are implemented in the PADRES publish/subscribe system and evaluated in a controlled local environment and a wide-area PlanetLab deployment. Atomic subscription notification delivery time improves by 20% in a well connected network, and composite subscriptions can be processed with 80% less network traffic and notifications delivered with about half the end to end delay.

Summary A complex software system is usually developed as a system of systems (SoS's) in which multiple constituent applications are composed and coordinated to fulfill desired system‐level requirements. To facilitate the interoperability of the constituent applications, they must be augmented with suitable coordination‐specific interfaces, through which they can participate in coordinated interactions. To increase the reusability of the applications and to increase the comprehensibility of SoS's, suitable mechanisms are required to modularize the coordination rules and interfaces from the constituent applications. We introduce a new abstraction named as architectural event modules (AEMs), which facilitates defining constituent applications and desired coordination rules as modules of SoS's. AEMs modularly augment the constituent applications with event‐based interfaces to let them participate in coordinated interactions. We introduce the EventArch language in which the concept of AEMs is implemented, and illustrate its suitability using a case study in the domain of energy optimization.

The convergence of technologies and information-driven applications require a middleware that supports data streams. This middleware needs to interpret, aggregate, filter and analyze streams of messages usually in a distributed environment. Publish/Subscribe middleware basically deals with some of these issues, but it is typically monolithic and includes only a subset of features. A problem arises when users want to find a middleware that completely fulfills their application requirements. Based on our experience, we propose a framework that allows the configuration/adaptation of a Pub/Sub solution based on a reusable and extensible set of components.
