The little and large of publish/subscribe: ever the twain shall meet?

ABSTRACT

Publish/subscribe is a popular event dissemination mechanism, providing anonymous, store-and-forward message distribution. Such systems have been deployed in quite small application environments, such as body area networks for patient health monitoring; they have also been deployed in extremely large distributed application environments, such as stock price distribution systems.

The AMUSE project in the UK is a collaboration between computing researchers at the University of Glasgow and Imperial College London. This project is focused on the concept of self-managed cells (SMC) as the basic unit of autonomous computing, and the federation of such cells at different levels of scale. Publish/subcribe implementations form the basis of SMCs at all levels of scale, and the federation of these P/S implementations forms the basis of SMC-SMC interactions.

This talk will present the P/S systems at the heart of small and large scale SMCs, and explore their federation. The efficacy of such federations will be discussed, and lessons learned recounted.
