Traffic Models for Telecommunication Services with Advance Capacity Reservation
Abstract Certain new telecommunications services such as videoconferencing are based on the advance reservation of transmission channels. The corresponding traffic process is quite different to that of traditional telecommunications services and usual teletraffic models seem inadequate for system performance evaluation and network dimensioning. We discuss implied teletraffic issues and attempt to describe the reservation process by mathematical models. In particular we derive formulae useful for dimensioning a videoconference network to a low blocking probability grade of service standard.
