Communication protocols form the operational basis of computer
networks and tele communication systems. They are behavior
conventions that describe how com munication systems inter act 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
proto cols, 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 represen tative 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.
