Protocol Engineering

Publisher: Springer Science & Business Media
Release Date: 2012-10-08
Communication protocols form the operational basis of computer networks and telecommunication systems. They are behavior conventions that describe how communication systems interact with each other, defining the temporal order of the interactions and the formats of the data units exchanged – essentially they determine the efficiency and reliability of computer networks. Protocol Engineering is an important discipline covering the design, validation, and implementation of communication protocols. Part I of this book is devoted to the fundamentals of communication protocols, describing their working principles and implicitly also those of computer networks. The author introduces the concepts of service, protocol, layer, and layered architecture, and introduces the main elements required in the description of protocols using a model language. He then presents the most important protocol functions. Part II deals with the description of communication protocols, offering an overview of the various formal methods, the essence of Protocol Engineering. The author introduces the fundamental description methods, such as finite state machines, Petri nets, process calculi, and temporal logics, that are in part used as semantic models for formal description techniques. He then introduces one representative technique for each of the main description approaches, among others SDL and LOTOS, and surveys the use of UML for describing protocols. Part III covers the protocol life cycle and the most important development stages, presenting the reader with approaches for systematic protocol design, with various verification methods, with the main implementation techniques, and with strategies for their testing, in particular with conformance and interoperability tests, and the test description language TTCN. The author uses the simple data transfer example protocol XDT (eXample Data Transfer) throughout the book as a reference protocol to exemplify the various description techniques and to demonstrate important validation and implementation approaches. The book is an introduction to communication protocols and their development for undergraduate and graduate students of computer science and communication technology, and it is also a suitable reference for engineers and programmers. Most chapters contain exercises, and the author's accompanying website provides further online material including a complete formal description of the XDT protocol and an animated simulation visualizing its behavior.
Modbus Protocol Engineering
"Modbus Protocol Engineering" "Modbus Protocol Engineering" provides a definitive and comprehensive exploration of the Modbus protocol, a foundational pillar of industrial communications. The book meticulously examines Modbus from its origins and standardization to its pivotal role in modern automation environments. Through detailed chapters on system architecture, protocol layering, addressing schemes, and device identification, readers will gain a deep understanding of the protocol’s core concepts and how it seamlessly integrates with the OSI model to facilitate robust industrial networking. The text moves from theoretical constructs into detailed, practical guidance covering Modbus communication modes, including RTU, ASCII, TCP/IP, and even alternative transports such as UDP. It goes further to dissect physical layer topologies, electrical considerations, and software implementation techniques. Rich coverage of application-layer design—standard and custom function codes, data mapping, error handling, and security—ensures that engineers and developers are equipped to design, deploy, and optimize Modbus networks for reliability, scalability, and efficiency. Dedicated sections on performance tuning, scalability, and high-availability architectures provide essential insights for large-scale and mission-critical deployments. Security and interoperability are addressed with rigor, offering strategies for defending Modbus environments against modern threats and facilitating integration with SCADA, DCS, and IIoT systems. The book rounds out its technical deep-dive with advanced topics, including wireless and edge computing adaptations, AI-driven analytics, open-source initiatives, and emerging security standards. Enriched with real-world case studies and actionable best practices, "Modbus Protocol Engineering" is an essential resource for automation engineers, protocol designers, and industrial IoT practitioners seeking both foundational knowledge and advanced expertise.
