Three-tier replication for FT-CORBA infrastructures
Software—Practice & Experience
Hi-index | 0.00 |
The handling of Interoperable Object Group References (IOGRs) is one of the basic building block of any FT-CORBA compliant platform. In this paper we introduce two basic components: IOGRManager, a tool to create, update, browse IOGRs, and an Outgoing-Request-GateWay (ORGW), a CORBA compliant client request interceptor, which allows clients running on non-FT-CORBA compliant ORBs to transparently interact with replicated objects residing on FT-CORBA-compliant platforms. Both components have been developed in the context of Interoperable Replication Logic (IRL) project that investigates the impact of three-tier architectures on software replication.
