Live evaluation of quality of experience for video streaming and web browsing

Web browsing and Video download are two major applications of the Internet. To evaluate Quality of Experience (QoE) of these applications, we have developed two tools: (i) pytomo, a tool that executes video download and emulates playback as performed by the Flashplayer plugin. A live web interface for visualisation also gives user information about main indicators for troubleshooting. (ii) CPM, a Firefox plugin that records main events during Web page download to perform a “post-mortem” Critical Path Analysis, indicates to the end-user or Web developer which objects of a given Web page determines the overall page load time.
