Corba Group Communication

With increasing popularity of CORBA for constructing distributed applications that can operate in a heterogeneous, distributed computing platform, need for providing fault tolerance support to CORBA objects is increasing. Group communication services have proven to be extremely useful in constructing fault-tolerant objects. However, current group communication services have mostly been implemented on a homogeneous, distributed computing environment. This limits their applicability, because most modern distributed computing environment are heterogeneous in nature. In this project, we investigate the design and implementation of group communication services using CORBA. The following publications describe some of the results of this project for a local-area network. The next step in this project is to explore design and implementation techniques for a wide-area, CORBA group communication service.
