Some operational tools in a OSI protocols study environment

Abstract

This paper deals with a strategy for a development chain of protocols (specification, validation, conformity testing) based on knowledge of the RHIN project methodology and the tools which this project produced. This methodology is based on finite state machines with predicates and includes “conceptual” tools for specification (PDIL)and for validation (VADILOC). “Experimental” tools play a part in conformity testing (STQ, Cerbere, Genepi). The interaction between conceptual and experimental tools is provided by a test sequence generator GAST which, starting from an automaton whose communication has been validated, provides sequences to be used by the test tools.
