Abstract
The invention relates generally to data communication networks and more particularly to a method of bandwidth management in a multiservice connection-oriented network which uses one or more overlooking factors and one or more overbooking models. The method allows an edge node which has received a connection request to accurately determine the bandwidth available on a given link in the network, by ensuring that different overlooking models and different overbooking factors are normalized at the edge node. The method of the present invention comprise: receiving at a selected one of the edge nodes updates from each of the core detailing a bandwidth management model, one or more overbooking factors and the link capacity associated with each of the core nodes; receiving at the selected one of the edge nodes a connection request; determining at the selected one of the edge nodes a preferred route through the network by accounting for a variation in overbooking factors or bandwidth management models between the selected one of said the nodes and each of the core nodes.
