Nous proposons une méthode efficace de mise à niveau et d'expansion du réseau qui permet de tirer le meilleur parti des ressources de canaux de nouvelle génération pour s'adapter à de nouvelles augmentations du trafic. Une configuration de réseau semi-flexible et deux mesures de coûts sont introduites pour établir une régularité dans l'attribution des fréquences et minimiser les perturbations dans le processus de mise à niveau ; les deux réduisent la fragmentation dans l’attribution des fréquences et le nombre de fibres nécessaires. Diverses études sur différentes configurations montrent que le nombre de fibres nécessaires est réduit d'environ 10 à 15 % pour toute combinaison de scénario de mise à niveau, de bande passante de fréquence de canal et de topologie adoptée.

Abstract: We propose an efficient network upgrade and expansion method that can make the most of the next generation channel resources to accommodate further increases in traffic. Semi-flexible grid configuration and two cost metrics are introduced to establish a regularity in frequency assignment and minimize disturbance in the upgrade process; both reduce the fragmentation in frequency assignment and the number of fibers necessary. Various investigations of different configurations elucidate that the number of fibers necessary is reduced about 10-15% for any combination of upgrade scenario, channel frequency bandwidth, and topology adopted.
