QCG Notification

QCG Notification is an open-source implementation of the family of WS-Notification standards (version 1.3). In the context of QosCosGrid, it is used to extend features provided by QCG BES/AR by adding standards-based synchronous and asynchronous notification features. QCG Notification supports the topic-based publish/subscribe pattern for asynchronous message exchange among Web services and other entities, in particular services or clients that want to be integrated with QosCosGrid. The main part of QCG Notification is based on a highly efficient, extended version of the NotificationBroker, managing all items participating in notification events. Today, QCG Notification offers sophisticated notification capabilities, e.g., topic and message content notification filtering, pull-and-push styles of transporting messages. QCG Notification has been integrated with a number of communication protocols as well as various Web services security mechanisms. The modular architecture of QCG Notification makes it relatively straightforward to develop new extensions and plugins to meet new requirements. The architecture of QCG Notification is presented in the following diagram.
