Abstract
A communications multi-service network arrangement for transporting information packets from a user station to a destination comprises a label switched core network constituted by a plurality of abstract nodes interconnected by tunnels. Each abstract node comprises one or more real nodes. An access network provides user access to the core network. A route across the core network comprises a plurality of label switched path sections specified in terms of a sequence of abstract nodes, the route being identified by a label stack identifying a quality of service capable connection from the end station via the access network to the core network and across the core network to a destination.
