Book Description
SDL (the Specification and Description Language for Telecommunication Systems) has evolved into a fully-fledged tool for the specification of telecommunication (sub-)systems, and is proving its fitness for major applications. The current (1988) version, the subject of this book, is used in the specification of the Functional Reference Model for Integrated Broadband Communication being studied in RACE, the European Community R&D programme in Telecommunications. For the many potential users of SDL, whether in industry or in the operating companies, this book should be of great practical value. By using worked examples from actual telecommunications engineering practice, and by explaining conceptual choices as they are made, it will enable students to learn the many features of the language in coherent combinations, and thus inspire correct usage from an engineering point of view. I congratulate the authors on their initiative and wish their readers success in mastering this invaluable addition to the tools-of-the-trade. From the preface by Rudolf W. Meijer, Commission of the European Communities Directorate General Telecommunications, Information Industries and Innovation

Book Description
CCITT (now ITU-T) Specification and Description Language (SDL) and systems engineering (formal and informal) in SDL are considered in this publication. The latest version of the language, SDL-92 [ITU Z.100 SDL-92] is introduced. The book has been written for existing and potential users of SDL - technologists involved in the specification and engineering of systems. It offers easier learning, through examples and application, than the Z.100 Recommendation of March 1993, which gives precise technical definitions and concepts. The book has sufficient coverage of the language so that for normal use it should not be necessary to consult Z.100. For this reason, the grammars, both textual and graphical, are included, and the index makes it possible to find text on most of the language mechanisms. Chapter 1 provides an overview of specification and design of telecommunication systems. It considers the usage and scope of SDL. Chapter 2 gives an overview of the language, with an introduction of the major language elements. Chapter 3 focuses on the specification of behaviour and the information interchange between processes. Chapter 4 covers the structuring of systems in terms of instances, how these may be defined by types and how types may be organised in type/subtype hierarchies by inheritance. Parameterised types and packages of type definitions are also covered. Chapter 5 presents the part of the language that provides data types, with emphasis placed on how to use predefined data types. Chapter 6 presents the use of SDL for system engineering, with a discussion of general systems engineering principles followed by an introduction to methodologies which use SDL. The use of other languages in combination with SDL, documentation issues, naming and other lexical rules, errors and language support are considered, since they are more relevant to the use of language in engineering than when initially learning the language.

Book Description
SDL (Specification and Description Language) is a modern, high-level programming language intended for the description of complex, event-driven, real-time and communicating systems. SDL was originally designed to describe performance-critical, real-time systems with precision and accuracy, and, if used correctly, it can significantly enhance the performance of system designs. This text is unique in the integration between performance and design issues, describing the specific problems encountered when specifying, designing and implementing communication systems with SDL, and offers experience-based advice and solutions. Other topics covered include * Navigating through complex design processes * Strategies for deriving efficient implementations from SDL descriptions * The latest version of SDL, SDL-2000 Systems Engineering with SDL also includes a CD-ROM containing a demonstration version of Telelogic's SDL design suite 'Tau' - the market leading SDL design tool which further reinforces the comprehensive integration between theory and practice. Written by a former system architect at Alcatel who currently serves on the ITU standards body for SDL, responsible for the development of performance and time aspects of the standard, this valuable reference resource is principally of use to practitioners using SDL to develop communicating systems, communication protocols, distributed systems, embedded systems, especially systems architects, development engineers and tool builders making strategic design decisions. However, the comprehensive coverage and concise and practical style make this text also applicable to students on graduate level courses on protocol engineering, communication systems engineering and distributed systems.

Book Description
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: ObjectGeodeTM and Tau SDLTM 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 ObjectGeodeTM and Tau SDL SuiteTM Practice 156 hands-on exercises with solutions. The SDL models and scripts used in the exercises can be downloaded from the Web.

Book Description
Features are modifications to the control of telecommunications services. A feature interaction occurs when the behaviour of another, which can lead to unexpected or undesired behaviour, which affects the quality of service. The goal of this volume is to generate a combination of techniques through protocol engineering, software testing, formal techniques and AI and applications to telecommunications services.

Book Description
The complexity of most real-time and embedded systems often exceeds that of other types of systems since, in addition to the usual spectrum of problems inherent in software, they need to deal with the complexities of the physical world. That world—as the proverbial Mr. Murphy tells us—is an unpredictable and often unfriendly place. Consequently, there is a very strong motivation to investigate and apply advanced design methods and technologies that could simplify and improve the reliability of real-time software design and implementation. As a result, from the first versions of UML issued in the mid 1990’s, designers of embedded and real-time systems have taken to UML with vigour and enthusiasm. However, the dream of a complete, model-driven design flow from specification through automated, optimised code generation, has been difficult to realise without some key improvements in UML semantics and syntax, specifically targeted to the real-time systems problem. With the enhancements in UML that have been proposed and are near standardisation with UML 2. 0, many of these improvements have been made. In the Spring of 2003, adoption of a formalised UML 2. 0 specification by the members of the Object Management Group (OMG) seems very close. It is therefore very appropriate to review the status of UML as a set of notations for embedded real-time systems - both the state of the art and best practices achieved up to this time with UML of previous generations - and where the changes embodied in the 2.
