Transactional Service Level Agreement?Service Level Agreement • December 5th, 2007
Abstract. Several models based on process calculi have addressed the definition of linguistic primitives for handling long running transactions and Service Level Agreement (SLA) in service oriented applications. Nevertheless, the approaches appeared in the literature deal with these aspects as independent features. We claim that transactional mechanisms are relevant for programming multi-step SLA negotiations and, hence, it is worth investigating the interplay among such formal approaches. In this paper we propose a process calculus, the committed cc-pi, that combines two proposals: (i) cc-pi calculus accounting for SLA nego- tiation and (ii) cJoin as a model of long running transactions. We provide both a small- and a big-step operational semantics of committed cc-pi as labelled tran- sition systems, and we prove a correspondence result.
