Agent Interaction Protocols in Support of Cloud Services Composition

摘要

Combining different independent cloud services necessitates a uniform description format that facilitates the design, customization, and composition. In this context, Interaction Protocols (IP) are a useful way for structuring communicative interaction among business partners, by organizing messages into relevant contexts and providing a common guide to the all parts. The challenge here is twofold. First, we must provide a formal model that is rich enough to capture interactions characteristics. Second, we must allow designers to combine existing protocols to achieve a new specific need. The paper introduces a formal analysis framework allowing the composition of IP. This framework is based on our previous work [7] [8]. In this paper, we mainly focus on the compositions of IP, where particular protocols may then be selected and composed to support a desired business application.
