A method of adapting an association of physical resources with a summarized resource in a hierarchical routed network. The method comprises monitoring at least one parameter of the physical resources. The method comprises adapting the association of physical resources with the summarized resource, based on the monitoring.

Method and apparatus of adapting an association of physical resources with a summarized resource

The present proposal provides a specific solution for communications network topology summarization with a good trade-off between high scalability, good stability and resources utilization efficiency.

Building topology in communications networks

A method is provided for routing data packets across a multi-layer network which includes a plurality of nodes, a logical level provided with a plurality of logical links and a physical level provided with a plurality of physical links, each of the logical links corresponding to at least one of the physical links, the method comprising the steps of assigning a weight to each logical link with respect to a first critical constraint in the logical level, refining the weight assigned to each logical link with respect to a second critical constraint in the physical level and, based on the weights assigned to each link, computing a path at the logical level connecting a start node to an end node for the transport of the data packets.
