The invention concerns a method for producing a telecommunication network, comprising the steps of determining geographical locations of exchange nodes and equivalent distances between these, and traffic capacities between node pairs based on the expected traffic volume between the respective nodes. The node pairs are at first sorted such that an expression S for each node pair is non-decreasing, S being a strictly monotonic increasing function of the equivalent distance and a strictly monotonic decreasing function of the traffic capacity between the nodes of the pair. For each node pair in this order, then a path P is selected for implementation among all possible paths, which path P satisfies the condition that (I) is minimum. In this expression k, n is an index for all links of the path and for all links of the path not yet selected for implementation in any previous step, respectively, C1 is selected in accordance with link implementation costs per distance unit, C2 is selected in accordance with link implementation costs per distance unit and per traffic capacity unit, Dk and Dn are the equivalent distances for the node pair belonging to link k and to link n, respectively. |
