An Experimental Loop-type ATM-LAN System using Onboard Distributed Switch Architecture and Evaluation of Transmission Delay

Abstract

In a network for an information and control systems, real time communication of large volume data and transmitting multimedia information such as video and voice has been required. In response to realize these requirements, introduction of an ATM (Asynchronous Transfer Mode)-LAN have been investigated. This paper describes an experimental loop-type ATM-LAN for control use utilizing an onboard distributed architecture. Realization method of a loop control mechanism (abortion of loop round-trip cells and loop-back control) using ATM switch function to miniaturizing a hardware and transmission delay of cyclic data communication caused cascade connection of an ATM switch is obtained.
