An Interoperable Replication Logic for CORBA systems

Abstract

The Replication Logic is a set of protocols, mechanisms and services that allow a CORBA system to handle object replication. We present a specific implementation of a Replication Logic, namely Interoperable Replication Logic (IRL), which exhibits nice properties like non-intrusion (i.e., the replication logic is built "above" the ORB) and interoperability (i.e., a client can reside on an ORB while server replicas reside on other, possibly distinct, ORBs). We compare IRL to other CORBA systems implementing replication logic such as Eternal, OGS, DOORS, Isis+Orbix, etc.
