TRANSFORMATION OF UNSTRUCTURED NETWORK INFRASTRUCTURES TO STRUCTURED VIRTUAL TOPOLOGIES ADAPTED TO SPECIFIC ROUTING ALGORITHMS

摘要

A method of extracting, from a physical topology, a virtual topology, the physical network topology including a plurality of switches connected to each other using their ports, the method comprising the following steps: sub-topology distribution of leaf switches according to the characteristics of the target topology, these subtopologies being included in the virtual topology; - inclusion of the neighboring switch (s) connected only to or to the switches (s) of the same subtopology to this subtopology; - Split neighboring switch (s) connected to a first subtopology and a second subtopology in two virtual switches, the first virtual switch comprising the ports of this neighbor switch with which it is connected to said first subtopology, the second virtual switch comprising the ports of this neighbor switch with which it is connected to said second subtopology.
