Abstract: Determining, in a transport network, a link between a source and a destination. The network is partitioned into subnetworks between which sublinks are determined. Each subnetwork has access points which indicate the transport capacity of the subnetwork between the access points. The sublinks, in each case, extend from a first access point to a second access point. In a network having a distributed control, the sublinks are determined successively between the link already determined and a remaining subnetwork. In this arrangement, the remaining subnetwork, in each case, includes an access point already associated with the destination and does not include an access point already associated with the link. Preferably, the access points, in each case, indicate the available capacity of a subnetwork.
