Abstract:
1. A method for tracking network parameters in a communication network formed with nodes and links between the nodes, with access controls for the purpose of limiting a traffic load, wherein the network parameters comprise a link/cost metric with link weights for the links, the method which comprises the following steps, to be performed by a control server: a) regularly determining a traffic matrix for the network; b) determining from the current traffic matrix a blocking probability for traffic, which is subject to an access control; c) performing a check to determine whether the blocking probability satisfies a criterion for a scheduled network operation; d) if the blocking probability does not satisfy the criterion and/or a redetermination for limits used as part of the access controls using the current traffic matrix does not lead to a blocking probability satisfying the criterion, using the current traffic matrix to determine a new link/cost metric for optimizing the transport of traffic through the network; e) determining new values for limits used as part of the access controls on the basis of the new link/cost metric and, following the determination of the new values for the limits, performing a check to determine whether the criterion is satisfied when the limits are re-established at these values; f) if the criterion is satisfied, configuring the link weights with the new link/cost metric in the network and establishing the limits at the new values.
