Abstract: A device for controlling network routing configurations is configured to obtain a predicted traffic matrix and a plurality of traffic matrices, and to determine, from a plurality of clusters, arranged in a hierarchical structure over the predicted traffic matrix and the plurality of traffic matrices, a first cluster allocated to a lower hierarchy level that contains the predicted traffic matrix. Each of the clusters is associated with a routing configuration, and the plurality of clusters are allocated to at least two different hierarchy levels. The device selects, from the plurality of clusters, a second cluster allocated to a higher hierarchy level that includes at least the first cluster and a third cluster allocated to the lower hierarchy level that contains a current traffic matrix, determine a second routing configuration associated with the second cluster; and activate the second routing configuration as a network routing configuration.
