| 20080212593 | Automatic Adaptation of Quality of Service Over Packet-Switched Networks - An end node in a packet-switched network is proposed wherein the end node is arranged to exchange packets consisting of a packet header and payload data with a server node connected to the packet-switched network. The end node includes at least one module adapted to extract quality of service parameter values from the headers of packets received over the packet-switched network and to insert the extracted quality of service parameter value in the headers of packets destined for transmission to the server node over the packet-switched network.
