Principles of Protocol Design - Sharp, Robin

. .

Résumé :
This book introduces the reader to the principles used in the construction of a large range of modern data communication protocols. The approach we take is rather a formal one, primarily based on descriptions of protocols in the notation of CSP. This not only enables us to describe protocols in a concise manner, but also to reason about many of their interesting properties and formally to prove certain aspects of their correctness with respect to appropriate speci?cations. Only after considering the main principles do we go on to consider actual protocols where these principles are exploited. This is a completely new edition of a book which was ?rst published in 1994, where the main focus of many international efforts to develop data communication systems was on OSI ? Open Systems Interconnection ? the standardised archit- ture for communication systems developed within the International Organisation for Standardization, ISO. In the intervening 13 years, many of the speci?c protocols - veloped as part of the OSI initiative have fallen into disuse. However, the terms and concepts introduced in the OSI Reference Model are still essential for a systematic and consistent analysis of data communication systems, and OSI terms are therefore used throughout. There are three signi?cant changes in this second edition of the book which p- ticularly re?ect recent developments in computer networks and distributed systems.

Biographie:
After obtaining a Ph.D in physics from Cambridge University, Robin Sharp has been working in the IT area since the early 1970s. He has many years experience in the design and analysis of computer networks, both at the academic level and in collaboration with industrial companies. He is currently an emeritus profesor at DTU Compute, the Department of Applied Mathematics and Computer Science at the Technical University of Denmark (DTU), where he has been employed since 1973. He is the author of the book Principles of Protocol Design on network protocols, whose second edition was published by Springer Verlag in 2008. His book What's Cybersecurity All About?, aimed at ordinary computer users, was published by Polyteknisk Forlag, the university publishers at DTU, in 2020. Since the 1990s, the main focus of his work has been on security in networks and methods for secure design of computer systems. This has included work on aspects of human interaction with computer systems and its affect on cybersecurity. He has had the operative responsibility for IT security as CISO at DTU Compute. Robin Sharp is an experienced teacher, having taught courses on computer security and network security since the middle 1990s, including a course for non-IT specialists, which has been an inspiration for the current book....

From the reviews: This book takes an unusual path to describe computer network protocols. ... Robin Sharp starts from formal description techniques. More precisely, he chooses the Communicating Sequential Processes (CSP) notation proposed by Hoare. ... could be of interest to readers who are more interested in the application of formal description techniques to network protocols. (IEEE Network, September/October, 2008) The book particularly reflects the recent developments in computer networks and distributed systems with special reference to applications. A number of new protocols are introduced with a focus on their current application, what is good stuff for students and researchers in the area. ... The book could be used for undergraduate third and fourth year courses in computer science and the network area. I am sure that this book will be a valuable asset in the educational and scientific community at large. (Aniket Mahanti, Zentralblatt MATH, Vol. 1142, 2008)
