Asynchronous Transfer Mode (ATM) has revolutionized telecommunications, and has become an integral part of the networking infrastructure. This introductory well--structured text on ATM networks describes their development, architecture, congestion control, deployment, and signalling in an intuitive, accessible way. It covers extensive background information and includes exercises that support the explanations throughout the book. The networking expert Harry G. Perros explains ATM networks, including such hot topics as: aeo ATM adaptation layer 2 aeo Quality of Service aeo Congestion control aeo Tag switching and MPLS (Multi--Protocol Label Switching) aeo ADSL--based access networks aeo Signalling aeo PNNI (Private Network Node Interface) An Introduction to ATM Networks is a textbook for graduate students and undergraduates in electrical engineering and computer science as well as a reference work for networking engineers. An Online solutions Manual is now available.
