Abstract
CRESS (CHISEL Representation Employing Systematic Specification) is a notation and set of tools for graphical specification and analysis of services. It is applicable wherever a system consists of base functionality to which may be added selected services. The CRESS notation is introduced for root diagrams, service diagrams, and rules governing their behaviour. It is shown how CRESS can represent services in SIP (Session Initiation Protocol). For analysis, service diagrams can be automatically translated into LOTOS (Language Of Temporal Ordering Specification) or SDL (Specification and Description Language). For scripting, translation is into CPL (Call Processing Language) or CGI (Common Gateway Interface). The structure of the portable CRESS toolset is explained.
