Abstract

Asynchronous Transfer Mode (ATM) has become one of the leading high-speed networking technologies in the local and wide area environments. ATM offers great promise to meet the real-time requirements of emerging multimedia applications. In the last few years, many ATM networks have been deployed and use different types of ATM switches, many of which differ in their implementations. In this paper, we explore the impact of two ATM switches, namely DEC GIGAswitch/ATM and IBM 8265 on the performance delivery of real-time digital video over native ATM connections. We also demonstrate experimentally the effects of different types of cross-traffic (delivered over both UDP/IP and native ATM) network loads on end-user application performance using QoS metrics such as jitter and packet loss.
