Description/Abstract

The requirements for collaborative services, especially pertaining to order and delivery, are quite different compared to traditional distributed applications. The NaradaBrokering 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. In this paper, we outline our rationale for incorporating these services and how these services interact with each other. We have conducted experiments related to profiling these services, and also on the performance and scaling of the messaging substrate. Our experimental results demonstrate that the substrate can indeed be used in scenarios where performance and scalability requirements are stringent.
