摘要

Nowadays, more and more applications are being developed through distributed object computing middleware, such as CORBA, their requirements for fault-tolerance, especially real time and critical system, become more and more critical. Despite almost ten years have passed since the earliest FT-CORBA standard was promulgated by Object Management Group (OMG), CORBA is still facing many challenges when it is used for distributed applications developing, as the standard is complex and lack of understanding. This paper focus on the consistency of the replicated object and the network partition problem, it incorporates a CORBA Replication Voting Mechanism (CRVM) to meet the challenge which makes a good performance.
