In order to meet the need of higher quality of service (QoS) for the new generation of Internet applications such as VoIP, video-on-demand and distance learning, we use the QoS technology in the network. We have studied the problems about QoS existing in networks, and the service models of QoS. A typical QoS principle experiment is designed. We elaborate the experiment process in a real network environment. In the experiment, QoS is applied to the File Transfer Protocol (FTP), and the transmission rate changes are measured and analyzed before and after applying QoS to different interfaces. The experimental results show that, QoS strategy can ensure the high priority data delivery and the implementation of QoS in multilayer switching network is successfully verified.
