In large measure the traditional concern of communications engineers has been the conveyance of voice signals. The most prominent example is the telephone network, in which the techniques used for transmission multiplex­ ing and switching have been designed for voice signals. However, one of the many effects of computers has been the growing volume of the sort of traffic that flows in networks composed of user terminals, processors, and peripherals. The characteristics of this data traffic and the associated perfor­ mance requirements are quite different from those of voice traffic. These differences, coupled with burgeoning digital technology, have engendered a whole new set of approaches to multiplexing and switching this traffic. The new techniques are the province of what has been loosely called computer communications networks. The subject of this book is the mathematical modeling and analysis of computer communications networks, that is to say, the multiplexing and switching techniques that have been developed for data traffic. The basis for many of the models that we shall consider is queueing theory, although a number of other disciplines are drawn on as well. The level at which this material is covered is that of a first-year graduate course. It is assumed that at the outset the student has had a good undergraduate course in probability and random processes of the sort that are more and more common among electrical engineering and computer science departments.

This unique text, for both the first year graduate student and the newcomer to the field, provides in-depth coverage of the basic principles of data communications and covers material which is not treated in other texts, including phase and timing recovery and echo cancellation. Throughout the book, exercises and applications illustrate the material while up-to-date references round out the work.

A timely and relevant analysis of today's complex call models In today's world of ever-expanding telecommunications options, here is an advanced-level text that covers the mathematical methods used in the analysis of modern telecom networks, with emphasis on a variety of call models such as quality of service (QoS) in packet-switched Internet Protocol (IP) networks, Asynchronous Transfer Mode (ATM), and Time Division Multiplexing (TDM). The authors move from basic principles to complex concepts and outline the fundamental steps toward modeling and analyzing each system. Illustrative numerical examples are carried out using three computational tools, Excel, Matlab®, and Maple. Refined and class tested for more than five years, Modeling and Analysis of Telecommunications Networks will benefit telecom researchers, students, and professionals alike, with thorough coverage that includes: *Plentiful numerical examples that illustrate the material covered and utilize the tools described *Complex concepts supported by extensive computations and detailed derivations *Analytical work complemented by a chapter presenting mathematical foundations of simulation *A complementary Web site with computational software that will be regularly updated with new examples and exercises
