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.

Abstract: A method, an apparatus and a non-transitory computer-readable storage medium for determining multiple disjoint constrained paths in a communications network are disclosed. The method includes selecting upper bounds QoS metrics for each path in a disjoint combination of paths having two or more disjoint paths between a source node and a destination node; determining a minimum-cost disjoint path combination, and a minimum-QoS metric disjoint path combination; computing a maximum QoS metric by summing the QoS metrics of each minimum-cost path in the minimum-cost disjoint path combination, and computing a minimum QoS metric by summing the QoS metrics of each minimum-QoS metric path in the minimum-QoS metric disjoint path combination.
