Traditionally, emulation systems have been unnecessarily written and compiled for specific computer architectures. Therefore, emulations cannot easily be ported to other computing platforms. This paper proposes a portable emulation system, where the dependencies on particular host architectures are minimised by developing the emulation runtime, in the portable environment Java. Using this syste...

In this paper we present our experiences from an emulation project of a real-world state-of-the-art design. We show common problems emulation novices usually encounter and give some hints and solutions to overcome these. Finally, we show the effort for typical emulation tasks. This is worthwhile information for all potential but inexperienced emulation users.

Emulation has evolved into a mature digital preservation strategy providing, inter alia, functional access to a wide range of digital objects using their original creation environments. In contrast to format migration strategies a functional, emulation-based approach requires a number of additional components. These can be provided by Emulation-as-a-Service, implemented and developed as a distr...

To analyze large-scale systems with high fidelity, it is necessary for a network testbed to offer both realistic emulation (to represent software execution) and effective simulation (to model background computation and communication). We present a network testbed that integrates a light-weighted emulation system OpenVZ (modified earlier to operate in virtual time) with a parallel discrete-event...

Emulation as a strategy for digital preservation is about to become an accepted technology for memory institutions as a method for coping a large variety of complex digital objects. Hence, the demand for ready-made and especially easy-to-use emulation services will grow. In order to provide user-friendly emulation services a scalable, distributed system model is required to be run on heterogene...

During the development of network protocols and distributed applications, their performance has to be analyzed in appropriate environments. Network emulation testbeds provide a synthetic, configurable network environment for comparative performance measurements of real implementations. Realistic scenarios have to consider hundreds of communicating nodes. Common network emulation approaches limi...

Software card emulation is a new approch to advance the interoperability of NFC with legacy contactless smartcard systems. It has been first introduced to NFC-enabled mobile phones by Research In Motion (RIM) on their BlackBerry platform. Software card emulation aims at opening and simplifying the complex and tightly controlled card emulation functionality. While this form of card emulation, th...
