Multiservice Loss Models for Broadband Telecommunication Networks
Loss networks ensure that sufficient resources are available when a call arrives. However, traditional loss network models for telephone networks cannot cope with today's heterogeneous demands, the central attribute of Asynchronous Transfer Mode (ATM) net

TO MY PARENTS
Preface The last decade of this century has seen dramatic increases in switching and transmission capacity, accompanied by an increasing need to integrate communication services - including voice, data, video and multimedia - over the same telecommunication network. These trends have led to the development of asynchronous transfer mode (ATM), a new standard for the transport of all telecommunication services over a common network. ATM is embraced by the voice, data and multimedia communities, and, within the next few years, is expected to be the dominant transport technology for all services in both the local and wide areas. A loss network is a collection of resources shared by calls. When a call arrives to find insufficient resources available, the call and its potential revenue are lost. Throughout the 20th century, telecommunication engineers have employed loss networks to model
