Managing adaptive fault tolerant CORBA applications

Abstract

Only very recently CORBA specification, with the adoption of the Fault Tolerant CORBA standard (FT-CORBA) [10], addressed issues concerning object replication and reliable communication between objects, which are key components to provide fault tolerance for distributed object systems. This work presents the design and implementation of Juggler/OGS+, a full featured FT-CORBA-like fault tolerance infrastructure. We have created OGS+, an extension of a CORBA Group Communication Service called OGS [6], and on top of it we developed Juggler, a distributed service that provides means for flexible and automatic management of fault tolerant CORBA applications through the deployment of a set of high-level mechanisms and interfaces based on the ones standardized in FT-CORBA. © Springer-Verlag Berlin Heidelberg 2003.
