Pour gérer efficacement une quantité croissante de trafic, des réseaux optiques élastiques (EON) capables d'utiliser les ressources du spectre optique de manière flexible ont été étudiés. Nous mettons en œuvre un routage multi-chemin au cas où nous ne pourrions pas allouer le spectre avec un routage à chemin unique. Cependant, le routage multi-trajet nécessite davantage de bandes de garde pour éviter les interférences entre deux chemins optiques adjacents par rapport au routage à trajet unique dans EON. Un algorithme de routage multi-chemins avec technologie de traitement du trafic a été proposé. Les chercheurs ont supposé qu’un niveau de modulation uniforme avait été adopté et n’ont donc pas pris en compte l’impact de la longueur du trajet sur les ressources nécessaires. Dans cet article, nous proposons une méthode de routage multi-chemins avec gestion du trafic prenant en compte la longueur des chemins. Notre méthode proposée établit un multi-trajet optique en tenant compte de la longueur du trajet, de l'utilisation de la fibre et de l'utilisation du traitement du trafic. Les simulations montrent que nous pouvons réduire la probabilité de blocage d'appels d'environ 24.8 % dans NSFNET. Nous démontrons également l’efficacité du traitement du trafic et l’amélioration du taux d’utilisation des ressources du spectre optique.

Abstract: To accommodate an increasing amount of traffic efficiently, elastic optical networks (EON) that can use optical spectrum resources flexibly have been studied. We implement multi-path routing in case we cannot allocate the spectrum with single-path routing. However, multi-path routing requires more guard bands to avoid interference between two adjacent optical paths when compared with single-path routing in EON. A multi-path routing algorithm with traffic grooming technology has been proposed. The researchers assumed that a uniform modulation level was adopted, and so they did not consider the impact of path length on the resources needed. In this paper, we propose a multi-path routing method with traffic grooming considering path lengths. Our proposed method establishes an optical multi-path considering path length, fiber utilization, and the use of traffic grooming. Simulations show we can decrease the call-blocking probability by approximately 24.8% in NSFNET. We also demonstrate the effectiveness of traffic grooming and the improvement in the utilization ratio of optical spectrum resources.
