Abstract
This paper assesses application-level QoS of both web access and voice-video streaming services on the Internet. We investigate how AFCP values in the two services affects their application-level QoS for various network scales, which are represented by the end-to-end delay between the Web server and the client. As a result of the experiment, we see that we can keep higher application-level QoS of the two services if the Web access service is offered as a different class from that of the streaming service or in the same class as that of the video flows with the video-flows' higher drop precedence. Furthermore, as the end-to-end delay increases, the effect of the choice of the AFCP values decreases. This implies that in such a network environment we do not need to give much consideration to AFCP marking.
