Abstract

Network emulation has been widely used to aid in the development and evaluation of real-time applications. Traditional emulation tools based on a single node machine or a cluster of machines cannot satisfy today's requirements for testing real-time applications distributed over wide area networks. ROSENET (RemOte SErver-based Network EmulaTion) is a network emulation approach that exploits a remote high-fidelity simulation to provide scale and accuracy for a low-fidelity emulator serving a locally executing real-time application. This paper evaluates the performance of an implementation of ROSENET using the NIST Net emulator and GTNetS simulator. Experimental results examining end-to-end delay and loss show that ROSENET provides a promising approach to network emulation supporting accuracy and scale while meeting real-time constraints.
