ABSTRACT: We study the effects of RED on the performance of Web browsing with a novel aspect of our work being the use of a user-centric measure of performance - response time for HTTP request-response pairs. We empirically evaluate RED across a range of parameter settings and offered loads. Our results show that:

We conclude that for links carrying only web traffic, RED queue management appears to provide no clear advantage over tail-drop FIFO for end- user response times.
