CA 2266005
The present invention relates to a method and related device to be used to establish a traffic based shortcut when running the Internet Protocol (IP) over a connection oriented network. Such a network may exists of a number of switch-routers and/or one or more IP-routers and/or one or more switches. The shortcutting is performed by the co-operation of the present IP-routers and or IP-router-parts. The described configuration manages the forwarding of Internet Protocol packet flows along a shortcut path. For each shortcut path set-up, a separate virtual channel connection is used. Only a restricted number of virtual channels is available for shortcut paths to be set up. To improve the efficiency of use of the available virtual channels, the time-out period of a shortcut path is determined depending on the local network load. By maintaining and using, an existing shortcut path to forward one or more IP packet flows simultaneously with, or subsequently to the first shortcutted flow the efficiency is increased as well.
