NCTUns is a Linux based network simulator/emulator which has a great deal of features such as the possibility to execute real world applications without modifications, and provision to model a wide range of network devices using real TCP/IP network stack. However NCTUns only supports simulation/emulation of mobile hosts instead of mobile networks. Hence, using the conventional NCTUns, it is not...

Dynamic emulation of mechanical loads presents a modern and interesting approach for testing and validating performance of electrical drives without a real mechanical load included in the test rig. The paper presents an approach to dynamic emulation of mechanical loads when the load torque and inertia mass of emulated load can be significantly greater than that of laboratory test rig. Closed-lo...

This document describes generic requirements for Pseudo-Wire Emulation Edge to Edge (PWE3). It provides guidelines for other working group documents that will define mechanisms for providing pseudo-wire emulation of specific services such as Ethernet, ATM, Frame Relay, TDM, and MPLS. It should be noted that the PWE3 Working Group (PWE3 WG) standardizes mechanisms that can be used to provide PWE...

Game preservation is a critical issue for game studies. Access to historic materials forms a vital core to research and this field is no different. However, there are serious challenges to overcome for preservationists in terms of developing a strategic and inclusion programme to retain access to obsolete games. Emulation, as a strategy already applied by major developers and the gaming communi...

QEMU is an open source emulator for complete PC systems. In addition to emulating a processor, QEMU permits emulation of all necessary subsystems, such as networking and video hardware. It also permits emulation of advanced concepts, such as symmetric multiprocessing systems (up to 255 CPUs) and other processor architectures, such as ARM or PowerPC. This article explores QEMU and its architectu...

This research statement describes the author’s PhD project, which targets the evaluation of sensor network designs in realistic environments. Network emulation includes a variety of methods and strategies for the evaluation of system designs for networked systems in safe testing environments. The author’s interest is to bridge the gap between generic simulation environments and real sensor netw...

Helge Backhaus, Denis Martin, and Hans Wippel attended this year’s IEEE Conference on Local Computer Networks 2009 in Zurich. There they presented a demonstrator based on research of the 4WARD and G-Lab project, as well as the IME graduate school (Fig. 1). The demo was created together with Lars Völker, Peter Baumung, and Benjamin Behringer. Selected concepts of the demonstrator include the des...

A fast fault simulation approach based on ordinary logic emulation is proposed. The circuit configured into our system that emulates the faulty circuit’s behavior is synthesized from the good circuit and the given fault list in a novel way. Fault injection is made easy by shifting the content of a fault injection scan chain or by selecting the output of a parallel fault injection selector, with...

In modern enterprise software environments, software systems often need to cooperate with other systems to fulfil their responsibilities. A significant challenge is how to assure the quality of such software systems before deploying them in realistic software environment. Enterprise software environment emulation is an emerging technique for quality assurance. By replacing software systems with...
