The Building of College Network Experiment Platform for IPv6 QoS

Abstract

This paper presents an object-event mechanism based overlay network simulation experimental platform (ONSP). The platform adopts object-oriented approaches to provide an effective application-layer active network simulation method. The method abstracts network elements, simulates the change of system performance through parameters setting, and introduces users session triggered by event. This strategy conducts experiments avoiding unnecessary construction of actual physical network, so that to save the cost of the experiment and to make mass network tests possible. At another time, the platform has established a complete performance evaluation model, and can synthetically measure the relative performance of variety of services to ensure the accuracy of test results. The productions in this paper will provide important support to overlay network services technology, QoS-assure technology, and applications of distributed multimedia systems.
