Error Correcting Coding and Security for Data Networks: Analysis of the Superchannel Conceptby Grigorii Kabatiansky
Synopses & Reviews
Error correcting coding is often analyzed in terms of its application to the separate levels within the data network in isolation from each other. In this fresh approach, the authors consider the data network as a superchannel (a multi-layered entity) which allows error correcting coding to be evaluated as it is applied to a number of network layers as a whole. By exposing the problems of applying error correcting coding in data networks, and by discussing coding theory and its applications, this original technique shows how to correct errors in the network through joint coding at different network layers.
By progressing from theory through to practical problem solving, this resource contains invaluable advice for researchers, postgraduate students, engineers and computer scientists interested in data communications and applications of coding theory.
Book News Annotation:
The text provides a systematic approach to the problems involved in the application of error-correcting codes in data networks. It includes theoretical material as well as concrete recommendations for the use of code in data networks as well as calculations of the benefits that error-correcting coding can help bring about. It's written for engineers who want to become more familiar with new approaches to the use of error-correcting codes and for readers interested in issues of data communication and applications of coding theory.

In this new approach, the authors consider the data network as a channel (in the sense of information theory) with several layers. The suggested global approach to coding in a network is consequently connected with other network procedures, such as protocols, and this determines complexity and originality of the problems of coding within the network. The authors distinguish different coding processes at 3 network layers (data link layer, transport layer and presentation layer) and investigate the impact of coding from one layer to another. Thus the problem of reconciliation of coding of different network layers arises and the authors suggest enlightening solutions to this problem.
The book consists of two parts:
PART 1 is mainly devoted to a review of coding theory and its applications. This part differs from the traditional monographs available on coding theory, as it focuses on nonbinary codes and the correction of special configurations of errors, dictated by a class of problems.
PART 2 discusses how to solve the problems raised in part 1 and is the main focus of the book. It shows how, with the help of coding which adds redundant packets to the message, it is possible to decrease the mean time of message delivery and increase the probability of not exceeding the acceptable delay limit. Methods of construction of a model of the discrete data channel and choice of the code for the data channel are presented. Many problems, considered in this part, have significance not only for data networks, but also for other sections of the communication theory.
