Video applications in E learning portal over WiFI/WiMAX networks: QoS evalution

摘要

ICT and e-learning platforms provide an alternative channel for improving the quality of education and extending it to reach broader audiences. In this paper, we evaluate the quality of network traffic when video applications are being used in e-learning portal over Wi-Fi/WiMAX environment. We design a network testbed together with the e-learning portal and PRTG is used to monitor the traffic in Wi-Fi / WiMAX environment. The assessments involved in four different traffic types which are the web traffic, file transfer and multimedia traffic. The experimental result shows that the quality of traffic when the video application is being used in e-learning portal is depending on the number of users accessing the portal at the same time. It also shows that the technologies used are performing at desired level.
