DISPOSITIF DE DETERMINATION DE CHEMINS DE COMMUNICATION DANS UN RESEAU DE COMMUNICATIONS A COMMUTATION D'ETIQUETTES, EN PRESENCE D'ATTRIBUTS DE SELECTION

摘要

The device has a memory unit (M1, M2) for stocking a table correspondence between a service data set and an information data representative of two criterions. A treatment unit calculates possible path between an outgoing (LER1) and destination node for finding an ideal path with respect to a performance of the paths on the criterions. The treatment unit associates the data route flow with a tag representative of the ideal path. The treatment unit receives a query of establishment of the path containing the set and assures a connectivity of network nodes with respect to the data for calculating the possible path. An Independent claim is also included for a tag switching router for a communication network.
