Abstract:
The increase need and interest in distributed technology has led to several different
types of object orientated middleware. CORBA is being defined by the Object
Management Group (OMG) and is the most commonly used middleware today for
building distributed applications. One of the fundamental requirements for a
distributed system is to communicate event information between objects. The
CORBA standard defines a specification of an Event Service that provides a flexible
model for asynchronous communication among objects. This thesis describes the
CORBA standard briefly and gives a detail account of the Event Service. The
CORBA Event Service specification lacks important features required by application
domains such as telecommunications and real-time systems. These limitations are
described along with the OMG proposals for a Notification Service and Messaging
Service that will overcome the various drawbacks. Also described is a comparison of
various event models both CORBA and non-CORBA based, that have been developed
by commercial companies and academic institutions.
This thesis describes the requirements, design and implementation of TCDEvents, a
Java implementation of the CORBA Event Service. Finally, the evaluation of
TCDEvents is compared with other CORBA and non-CORBA event models.
