Juggler: A Management Service for CORBA Object Groups

Since its initial specification, CORBA has become a de facto standard for the development of object-oriented distributed applications. In spite of some important features such as support for interoperability and heterogeneity, the CORBA specification neither addresses object replication nor reliable communication between objects yet, which are key components to provide fault tolerance for distributed object systems.

Some research projects have proposed and explored a few approaches that incorporate fault tolerance mechanisms in CORBA but most of the systems developed offer a rather basic support for managing groups of object replicas. Our work builds upon one of these systems, called OGS[Felber98].

On the top of it, we are developing Juggler, a distributed service that provides means for flexible and automatic management of CORBA replicated objects.
