Abstract
A path between a selected first node and a selected second node is identified in a telecommunications network. A system cost is estimated for making a connection between the first node and the second node, a potential first intermediate note interconnectable from the first node is identified and a first set of systems costs are estimated from said first intermediate nodes to said second node. In addition, the second intermediate nodes connectable from the second node are identified and a second set of systems costs are estimated from the second intermediate nodes to the first node. On the basis of a comparison between the first set of systems costs and the second set of systems costs, between the first and second nodes, a starting node and a target node are selected.
