Abstract

In this paper we present the failure management system of IRL (Interoperable Replication Logic), a FT-CORBA platform that provides transparent client/server interactions and server failovers to application clients by using a set of replicated CORBA objects (IRL components). The IRL failure management system includes two basic mechanisms, failure detection and recovery. Each of these mechanisms follows a service stack approach: (i) to reduce as much as possible the impact of the services in terms of network traffic and (ii) to use the same services both for application objects and for IRL components
