Research literature abound with many and diverse analytical approaches applied to the confusing mix of traffic, the switch design and traffic control mechanisms. Introduction to IP and ATM Design and Performance provides: recognition problem IP and ATM traffic; performance evaluation using analysis and simulation; presentation of key formulas describing traffic and queuing behavior and practical examples, graphs and tables for the design of wide area network. specific areas covered include the function of basic traffic control: control incoming connections; control the use of parameters, priority control, queue scheduling and buffer management. Features include: Expansion clear and typical traffic queuing behavior Simple exposition of fundamental performance evaluation methods and techniques for ATM and IP All formulas are available in Mathcad file-related web sites Avoiding the use of sophisticated mathematical methods Simple intuitive approach is easy to follow and will benefit both engineers in the telecommunications industry and undergraduate and postgraduate students in telecommunications, communications engineering, computer engineering courses.
