Abstract
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.
