Architecture of an emulator testbed for heterogeneous ATM/STM networks

Abstract

This paper describes the architecture of a network emulator designed and built at AT&T Bell Laboratories to model, design, and analyze high speed networks, particularly heterogeneous ATM/STM systems. The Bell Labs Network Emulator (BENE) serves as a testbed for several experiments involving transport of applications such as voice, video/conferencing, and fax/voice-band data over such networks.
