Abstract

Several synthesis methods have been proposed and applied to the design of computer communication protocols. Most of these methods do not use the service specification as a reference (or starting) point in the protocol synthesis process. Consequently, these methods do not guarantee that the synthesized protocol provides the specified services, and therefore must be complemented by a semantic validation technique. In this paper, we propose a new synthesis method which automatically derives protocol specifications from a service specification. Both the service and protocol specifications are modelled by finite state machines (FSM). The resulting synthesized protocol is guaranteed to be free from logical design (syntactic) errors and to conform to the service specification. Finally, the synthesized protocol is augmented by error-recovery patterns to enable recovery from transmission errors caused by an unreliable communication medium. The application of the new method to an example service is also presented.
