Worldwide messaging support for high performance real-time collaboration

The requirements for collaborative services, especially pertaining to order and delivery, are quite different compared to traditional distributed applications. The NaradaBrokering (NB) messaging substrate enables scalable, fault-tolerant, distributed interactions between entities, and is based on the publish/subscribe paradigm. The substrate also incorporates support for Grid and Web Service. More recently, we have incorporated services within the substrate which enable us to facilitate richer collaborative interactions. We have performed benchmark tests on machines in the USA, UK and Australia to gauge the performance and scalability of the NaradaBrokering substrate over worldwide networks using benchmarking software developed alongside NaradaBrokering with varying message payloads and large attachments over Parallel TCP. In this paper, we demonstrate how our results show that the substrate can indeed be utilised to achieve maximum performance in a collaborative messaging environment over worldwide networks with the ability to maintain performance notwithstanding scalability constraints
