Abstract

In order to increase flexibility and reduce complexity, the use of distributed platforms such as CORBA for building complex distributed systems is growing significantly. Although CORBA platforms provide a better support than conventional RPC mechanisms for deploying large distributed applications, few developments have been made so far to offer the necessary support for increasing reliability and fault-tolerance. We present here the behavior of inter-object communications in the CORBA reference, and compare it with the requirements of some type of applications, by focusing on reliability issues. Then we show how it is possible to bridge the gap between the specification and our requirements, when considering the problem of a server object generating information for a number of independent clients.
