The myGrid Notification Service
Krishna, Ananth and Tan, Victor and Lawley, Richard and Miles, Simon and Moreau, Luc (2003) The myGrid Notification Service. In: Proceedings of the UK OST e-Science second All Hands Meeting 2003, Nottingham, UK.
The notification service is the part of myGrid that enables asynchronous delivery of messages between distributed components. It includes features such as topic-based publish-subscribe messaging, push/pull models, asynchronous delivery, persistence, transient and durable subscriptions, durable topics, negotiation of QoS, hierarchical topic structure and federation of services. Some of these features are novel in the area of messaging middleware. A cost evaluation of some of these features indicate that the overhead incurred is justified in terms of compensating benefits gained.
