Queueing system with multiple delay and loss priorities for ATM networks

The asynchronous transfer mode (ATM) has been widely accepted as an effective technique to transport various traffics such as voice, data and video in broadband integrated services digital networks (B-ISDN). To utilize the network resources efficiently and to provide the required quality of service (QoS) of each traffic, a proper priority control is necessary. This paper investigates a priority queueing model with four types of traffics, classified according to the delay and loss sensitivity. A head-of-line (HOL) scheme for cell delay control and a push-out scheme for cell loss control are adopted. Some computational procedures for loss probabilities and waiting times are developed. Several numerical examples are also given. (C) 2001 Published by Elsevier Science Inc.
