There has been enormous growth in the usage of web browsing services on the Internet. The prime reason behind this usage is the widespread availability of World Wide Web (WWW), which has enabled users to easily utilize different content types such as e-mail, e-commerce, online news, social media and video streaming services by just deploying a web browser on their platform. However, the delivery of these content types often suffers from the delays due to sudden disturbances in networks, resulting in the increased waiting time for the users. As a consequence of this, the user Quality of Experience (QoE) may drop significantly. Therefore, in order to provide successful network services, it is important to assess the impact of network disturbances on the Web browsing QoE. In this work, user subjective tests were conducted in the context of web browsing services for an e-commerce website. The variety of network disturbances were introduced within different key parts of the web browsing transfer, such as DNS resolution, base object and the embedded objects on web pages. The main aim behind this study is to evaluate how the delay affects the QoE when applied within different parts of the transfer.
