Wiley Series in Communications Networking & Distributed Systems / Validation of Communications Systems with SDL

Validation of Communications Systems with SDL provides a clear practical guide to validating, by simulation, a telecom system modelled in SDL. SDL, the Specification and Description Language standardised by the International Telecommunication Union (ITU-T), is used to specify and develop complex systems such as GSM, GPRS, UMTS, IEEE 802.11 or Hiperlan. Since the downturn in the telecom industry, validating a system before its implementation has become mandatory to reduce costs. This volume guides you step by step through the validation of a simplified protocol layer, from interactive simulation to proof of properties using reachability analysis combined with observers. Every step is explained, using the two main SDL tools commercially available: ObjectGeode(TM) and Tau SDL(TM) Suite, both from Telelogic. Contents: * Short tutorial on SDL * Presentation of the protocol layer case study * Interactive simulation, MSC generation * Scripting, automatic non-regression * Auto matic validation against MSC, HMSC, etc. * Random simulation * Exhaustive and bit-state simulation * Errors detected and not detected by simulation * Other simulator features This book offers you the opportunity to: * Learn expert validation techniques and tips * Master advanced simulation features of Telelogic ObjectGeode(TM) and Tau SDL Suite(TM) * Practice 156 hands-on exercises with solutions. The SDL models and scripts used in the exercises can be downloaded from the Web.
