In this paper, we identify the middleware functionnalities andproperties that are required to efficiently implement the FaultTolerant CORBA specification. Our approach relies on certainproperties of PolyORB, our schizophrenic middleware to provide CORBA-based applications with fault tolerance. Our approach isvalidated by performance measures for the stateful replication stylesdefined in the standard and for the failure detection and notificationinfrastructure. Even if our current full Ada95 implementation requiresan optimization phase, it exhibits acceptable performances, compared toexisting implementations of this standard.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
