Abstract

Implementation and Evaluation of new Internet communication systems face some general problems. The implementation of Quality of Service concepts in kernel space is complex and time consuming, while the final setup of the evaluation networks lacks the desired size and flexibility. The usual alternative simulation cannot cope with the real world. This paper presents a concept to combine real components like hosts and routers with simulated nodes. This simplifies the setup of huge test scenarios and the implementation of new concepts, while keeping the evaluation results realistic. This paper presents the concept and the implementation of virtual routers by its application in a Differentiated Services Networks.
