PROSPEC: an interactive programming environment for designing and verifying communication protocols

The PROSPEC software environment for designing and verifying communication protocols is described. It integrates several tools that implement methods for protocol verification and construction (i.e., fair reachability analysis, multiphase construction, and protocol projection). The system provides a unified graphical interface to facilitate the application of these methods and creates an interactive environment for specifying, verifying, and designing communication protocols. PROSPEC was used successfully to design and verify versions of BSC, X.21, X.25, and Telnet document transfer protocols.<
