Abstract
The CORBA based middlewares are appropriate for Telematics system which is an important and practical infrastructure for ubiquitous convergence. And fault tolerance is a first priority for real time characteristics of transport information provided by Telematics systems. There are many methods to enhance the fault tolerance of CORBA based systems. Among these methods, this paper proposes the one of enabling seamless information services where systems based on the CORBA suffer from object faults which occur processing real time transport information. Namely, this paper observes a method to deal efficiently with object faults occurring in 3 tier architecture environments. It is possible to replicate objects as a method to enhance fault tolerance in preparation against object faults. This paper presents a method of enhancing Telematics fault tolerance and maintaining service continuity by continuing to operate systems until faults of the Fault Tolerant (FT)-CORBA protocol itself is recovered. The proposed agent enhances Telematics performance by adjusting the minimum number of object replicas for real time transport information services during system operation. The evaluation is performed by comparing costs for system fault tolerance which consist of communication traffic and S/W complexities.
