The ATM (Asynchronous Transfer Mode) network is regarded as effective for a
multimedia telecommunication environment that enables high-speed and broad
band communication. This paper reports on the system architecture and desig
n concept of the FETEX-150 ESP (Enhanced Switching Platform) which has been
designed as an ATM switch in a public broadband network. To track the late
st ATM standards and trends, a simple, scalable, and open architecture was
set forth for the FETEX-150 ESP design target at the beginning of the syste
m design. This paper also describes the method for traffic management to su
pport various traffic classes. (C) 1999 Elsevier Science B.V. All rights re
