Abstract

L'invention concerne un gestionnaire de trafic (30) qui détermine les emplacements géographiques de points terminaux dans le trafic Internet et aiguille ce trafic avec la plus grande efficacité. Un ensemble de dispositifs d'analyse servent à analyser le réseau, à savoir les emplacements géographiques de noeuds dans le réseau, les temps d'attente et la vitesse de communication entre les noeuds, la largeur de bande disponible, etc. Ce gestionnaire de trafic obtient cette information relative au réseau des dispositifs d'analyse et il aiguille le trafic en conséquence. Pour cela, ledit gestionnaire de trafic tient compte non seulement de l'itinéraire le plus direct, mais aussi de la vitesse, de la largeur de bande disponible et de la fiabilité de l'acheminement.
