Abstract (en)
[origin: WO0069210A2] The aim of the invention is to evaluate routes R in a communications network (KN) consisting of switching nodes (K) and of transmission paths (U). To this end, modified link costs (L) are established from link costs (LK) assigned to the transmission paths (U), preferably using random numbers, and the routes (R) are evaluated according to the modified link costs (L). If the modified link costs (L) are established with each call request, connections (V), which can be set-up along a number of routes (R) with identical minimal route costs (RK), are evenly distributed on these routes (R) while retaining existing routing algorithms.
