Abstract
A system based on service-oriented architecture is distributed in nature. Services can be obtained from various sources and assembled through loose coupling. This provides flexibility and scalability in development. On the other hand, involvement of multiple components in a systems causes new sources of faults. Faults may come due to individual services and their interactions during service composition. For reliable systems, one has to consider these newer faults and possibility of system functionality in presence of those faults. Hence, for avoiding failure of critical services in faults presence, fault tolerance needs to be incorporated in the system. In this paper, architecture analysis and design language (AADL) has been used to model different types of errors in a SOA based systems. The AADL is supplemented with error model annex (EMV) that helps to demonstrate error propagation, failure behavior of the design errors. These facilities of EMV are exploited for obtaining error propagations among components in SOA based systems. The proposed fault tolerance modeling may provide useful information for fault tolerance and software testing.
