Abstract
Event architectures provide various applications under distributed environment. Such applications include mobile computing, control systems, e-commerce, real time, system and network management. Different event models presently in use are Common Object Request Broker Architecture (CORBA), JINI and, Grid Simple Object Access Protocol (SOAP) systems. Recently, research and trial experiments are conducted with Session Initiation Protocol (SIP) Event framework an extension of the SIP. Though there are many such existing event architectures, interworking between these systems is still an open issue. In this thesis, the publish/subscribe(pub/sub) model, a communication paradigm for complex distributed applications and the SIP, newly emerging standard are considered. The pub/sub system works in a loosely-coupled manner offering one-to-many asynchronous event dissemination. In this model, anonymity between the publisher and subscriber can possibly be maintained. In contrast, the SIP event system supports solicited subscription and notification. In this thesis, an interworking architecture is proposed for the two different and, non-interoperable event systems namely, the pub/sub and SIP event framework. This thesis presents the gateway component designed to accomplish the goal of interworking between the pub/sub and SIP event systems. Future directions of research to enhance the proposed interworking architecture is discussed.Description
