A process for the adaptation of the link - weights in the view of an optimized distribution of traffic

摘要

The invention relates to a method for adaptation of the link - weights or link - costs (lk) for an optimized distribution of traffic within a communications network. In the method, a loop is passed through, to an interrupt criterion is fulfilled. The individual iterations include the following steps:Be it on the basis of link - costs (lk) paths (p (lk)) for the routing of traffic is calculated within the communication network. Values of a used for the optimization parameter (v (l)), for example, the link related traffic volume, are provided for the individual to the left (l) by means of the calculated paths (p (l)) and the expected volume of traffic (vm) is determined and the link (l (vmax, n)), for the of the parameters (v (l)) the highest value (vmax, n) has, is determined. If the specific maximum value (vmax, n) is not higher than the value (vmax, n - 1) with the preceding step (termination criterion), the link - costs (lk (l (vmax, n)) for the determined link (l (vmax, n)) is increased.The method permits a low-cost determination of link - costs (lk) and paths (p (lk)) for an optimized distribution of traffic.
