An infrastructure for CORBA component replication

Abstract

Traditionally applied to availability problems in various distributed computing domains (caching, fault-tolerance, disconnections), replication solutions remain difficult to implement and challenging to reuse. In this paper we propose a component-oriented approach in which replication is treated as a part of the configuration/reconfiguration aspect of an application. The approach allows an easy reuse of replication solutions and their integration through adaptation in existing distributed component-based services. We apply the approach to an implementation of the CORBA component model: OpenCCM.
