Abstract: A method for automatically assigning individual topological addresses to network switches includes obtaining first individual topological addresses each of which includes one identifier of a hierarchical level and N?1 non-hierarchical identifier(s) of the network switch with which it is associated, N?2. It further includes the transcoding of each first individual topological address by subdividing the N?1 non-hierarchical switch identifier(s) as a function of a value of the hierarchical level identifier into one or more sub-topology identifiers separated from one another by at least one first separator character, forming a first character string, and into one or more switch identifier(s) separated from one another by at least one second separator character, forming a second character string. A second hierarchical individual topological address is thus constituted by concatenation including the first and second character strings, as well as a third separator character therebetween.

Abstract: An interconnection network simulator of computational nodes includes in particular a topology simulation module constructed and arranged to select and start a defined number of simulated modules, establish connection links between the started simulated modules so as to form a simulated interconnection network, and enable a user to interact with the started simulated modules.

Abstract: A method of extracting, from a physical topology, a virtual topology, the physical network topology including a plurality of switches connected to each other by their ports. The method includes the following steps: distribution of the leaf switches into sub-topologies according to the characteristics of the target topology, the sub-topologies being included in the virtual topology; inclusion of the neighboring switches connected only to the switches of a same sub-topology to the sub-topology; splitting of neighboring switches connected to a first sub-topology and to a second sub-topology into two virtual switches, the first virtual switch having the ports of the neighboring switch by which it is connected to the first sub-topology, the second virtual switch having the ports of the neighboring switch by which it is connected to the second sub-topology.
