Integrated Services Digital Network

Abstract: Growth in broadband integrated network technologies like ATM, ISDN, and frame relay has been phenomenal in recent years. This book focuses on the quantitative methods, such as modeling and performance analysis in the high-speed ATM networking environment, as opposed to qualitative overviews. Covers the types of services provided over ATM networks, the ATM protocol model, Broadband ISDN and ATM, traffic characterization, access control in broadband networks, ATM switches, effective capacity, and feedback congestion control. For communication specialists, especially those working in the telecommunications industry.

Abstract: Background information on networking and switching is provided, and the various architectures that have been considered for fast packet switches are described. The focus is solely on switches designed to be implemented electronically. A set of definitions and a brief description of the functionality required of fast packet switches are given. Three basic types of packet switches are identified: the shared-memory, shared-medium, and space-division types. Each of these is described, and examples are given. >

Abstract: Asynchronous transfer mode (ATM) networks, as proposed by CCITT as the solution for the future broadband ISDN, will provide high flexibility with respect to the varying bandwidth requirements of the different services. They will also support variable bit rates within a connection. The packetized information transfer, without flow control between the user and the network, in combination with the asynchronous multiplexing principle, results in a need to control the individual cell stream during the entire duration of the calls to ensure an acceptable quality of service for all coexisting calls sharing the same network resources. This kind of control will be provided by introducing a policing or usage parameter control function. Basic design objectives and requirements for such a function are described. These requirements serve as a basis for the comparison of some of the mechanisms proposed so far, namely the leaky bucket, the jumping window, the triggered jumping window, the moving window, and the exponentially weighted moving average mechanisms. >
