Resource allocation in broadband ISDNs

Broadband integrated services digital networks (BISDNs) have recently received significant attention among researchers in the field of telecommunications. These broadband telecommunication networks are being designed for handling, in their final form, a large variety of digital information, e.g., data, voice, video, facsimile, etc. Asynchronous transfer mode (ATM) has been recommended by the CCITT as a means of providing efficient and fast packet switched communication among BISDN users. It supports a large variety of services in a simple and unified fashion. An efficient and simple, yet effective, technique for resource allocation in broadband networks is presented. This technique was simulated for a network with three types of services and results are presented in terms of call blocking probabilities for several different cases.
