Towards Relaxed Rollback-Recovery Consistency in SOA

Nowadays, one of the major paradigms of distributed processing is SOA. To improve the reliability of SOA-based systems, a ReServE service that ensures recovery of consistent processing state, has been proposed. ReServE introduces a high overhead during failure-free computing. Thus, in this paper we propose relaxed recovery consistency models that allow optimization of rollback-recovery in SOA. We propose their formal definitions, and discuss the conditions under which these models are provided by ReServE.
