Abstract: Internet has dominated the modern communication and information exchange and it is growing enormously day by day. Initially it is designed to off?er various applications like World Wide Web (WWW), Electronic Mail (E-Mail) and File Transfer (FTP). WWW has become very popular and today, Web traffic constitutes 70-80% in global Internet traffic. Web traffic generates by the end users, when they request for a web page. The web page transfers between various Web servers via different service networks to the end users. Web traffic has become very significant in the present world and the service providers have to offer best service to the customers. Quality of Service (QoS) is a measure of describing the performance of the service. Quality of Experience (QoE) explains the user perceived performance and it is subjective in nature. QoE influences the user satisfaction level, so QoS has to ensure to promote better QoE. User perceived QoE depends on page download time and it is an important parameter in evaluating the performance of web service. In this work we try to correlate the web page download times at both application-level and network-level. In particular, when there is a considerable delay in the network, we tried to correlate the application perceived download time with network-level download time. We explained the difference between application and network download times and how it varies with the applied delay. This work also shows how the download times at both levels are related to each other and their coefficient of correlation.
