scope:

The present document focuses on Quality of Service (QoS) measurements for IP-based web content delivery services with reliable transport where primarily a visual presentation of the content on screen is available to the user. The presented test methodology is not limited to be applied to web browsing, or more general, to smartphone applications presenting web content visually on the screen. It can also be applied to all sorts of applications based on retrieving web conent. The present document does not target the qualitative evaluation of received content as video or audio.

The underlying test procedure consists of two phases: first request to resolve the initial URL and to contact the landing page, and second - if implemented - connect to embedded URLs to retrieve more and supplementary content. In the present document, web browsing serves as the default example, but the described QoS parameters can easily be applied to other IP-based web content delivery services based on reliable transport.

Furthermore, the present document also offers practical guidance for measurement execution and evaluation of HTTP/HTTPS content delivery QoS measurement.
