ABSTRACT

Title : BYZANTINE FAULT TOLERANCE MODEL FOR SOAP FAULTS
Authors : S. Murugan, V. Ramachandran

Abstract :
The proposed model is to configure Byzantine Fault Tolerance mechanism for every SOAP fault message that is transmitted. The reliability and availability are of major requirements of Web services since they operate in the distributed environment. One of the reliability issues is handling faults. Fault occurs in all the phases of Service Oriented Architecture i.e. during publishing, discovery, composition, binding, and execution. These faults may lead to service downtime, behaves abnormally, and may send incorrect responses. These abnormalities are classified as Byzantine faults in Web services. Even though SOAP specification provides fault handling mechanisms, the correctness of the received SOAP fault messages are not known. In this paper, a model is proposed to check the correctness of the SOAP fault message received, by incorporating the Byzantine agreement for fault tolerance. The existing fault tolerant mechanism detects server failure and routes the request to the next available server without the knowledge of the client. The proposed model ensures a transparent environment by providing fault handling information to the client. This is achieved by incorporating an active replication technique.
