Fusion network performance experiment

Abstract

Hybrid optical packet/circuit switched networking architectures are increasingly becoming an interesting research field. They integrate multiple switching techniques to achieve better quality of service and to improve resource utilization. The aim of this study was to investigate the performance of TransPacket FUSION Ethernet H1 node, which is being developed based on the original idea of OpMiGua hybrid optical network. The work was focused on several key performance elements: packet delay, packet loss rate and packet delay variation of the hybrid network. The research background and the quality of service methods utilized in hybrid network and OpMiGua were studied in this project. The performance of H1 node was tested based on one applicable scenario. We investigated and analyzed the results obtained from the Spirent test center, and derived a mathematical model of H1 node performance respect to each aspect. Furthermore, the experiment results were verified with usability of H1 node in comparison with the ITU recommendations. The results in our experiment scenario showed that H1 node provides a high quality of service.
