Abstract
An optimisation of the SS No. 7 Transport Capabilities Procedures is verified by specifying both the original and the optimised TCAP in CRL, generating transition systems for both using the CRL tool set, and checking weak bisimulation equivalence of the two using the Csar/Aldebaran tool set, these steps being part of a iterative process of specification, refinement and verification. As a result, the optimisation design is debugged, a deeper understanding of the protocol is gained, and the usability of the CRL tool set is evaluated. In conclusion, the design of an optimised TCAP indeed benefitted from the verification reported here, and CRL and Csar/Aldebaran appeared to be a largely adequate combination for the verification at hand; however, since the characteristics of TCAP were not explicit from the start, and the tools used covered the functionality required not perfectly, the verification required a good deal of human ingenuity and stamina. 1991 Mathematics Subject Classification:...
