Composition method of communication system specifications in asynchronous model and its support system

Abstract

One of the most important methods in communication system design, especially in protocol design, is the composition method. We propose a method for simultaneously composing service specifications and protocol specifications based on the LOTOS language. In this method, an asynchronous communication model is adopted which is more realistic in actual communication networks. We use the concept of the weak bisimulation equivalence to represent the correctness of composition. A software support system based on the proposed composition method is also described.
