Modelling and Analysis of Dynamic Reconfiguration in BP-calculus (2012)

Author(s): Mazzara M; Abouzaid F; Mullins J; Dragoni N

    Abstract: The BP-calculus is a formalism based on the pi-calculus and encoded in WS-BPEL. The BP-calculus is intended to specifically model and verify Service Oriented applications. One important feature of SOA is the ability to compose services that may dynamically evolve along runtime. Dynamic reconfiguration of services increases their availability, but puts accordingly heavy demands for validation, verification, and evaluation. In this paper we formally model and analyze dynamic reconfigurations and their requirements in BP-calculus and show how reconfigurable components can be modeled using handlers that are essential parts of WS-BPEL language.
