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. In this manner the end node automatically adapts the quality of service parameters received over the packet-switched network to correspond with the type of quality of service defined in received packets. Such a system means that only the server node need be configured with the quality of service parameters applicable on the particular packet switched network, so greatly reducing the installation and configuration overheads in a multi-user network. | 09-04-2008 |
