Le réseau défini par logiciel (SDN) dissocie le contrôle et le transfert des périphériques réseau, offrant des avantages tels qu'un contrôle simplifié. Cependant, en raison de contraintes de coûts et d’autres facteurs, le SDN est difficile à déployer entièrement. Il a été proposé que les appareils SDN puissent être déployés progressivement dans un réseau IP traditionnel, c'est-à-dire un SDN hybride, pour offrir des avantages partiels du SDN. Des études ont montré qu'il est possible d'obtenir de meilleures performances d'ingénierie du trafic en modifiant la couverture et le placement des appareils SDN dans le SDN hybride, car ils peuvent influencer le comportement des commutateurs existants grâce à certaines stratégies. Cependant, il est difficile de développer et d’exécuter une stratégie d’ingénierie du trafic dans un SDN hybride. Cet article propose un algorithme de routage pour obtenir un équilibrage de charge approximatif, qui minimise l'utilisation maximale des liens en utilisant la solution optimale de programmation linéaire et en fusionnant les flux de trafic divisés minimum. Un mécanisme de transfert multivoies répondant au même problème est conçu pour optimiser le temps de transmission. Les expériences montrent que notre algorithme présente certains avantages en termes d'utilisation des liens et de temps de transmission par rapport aux algorithmes de routage distribués traditionnels comme OSPF et certains mécanismes de routage hybrides SDN. De plus, notre algorithme peut se rapprocher de l'effet de contrôle du SDN complet lorsque le taux de déploiement des appareils SDN est de 40 %.

Abstract: Software-defined networking (SDN) decouples the control and forwarding of network devices, providing benefits such as simplified control. However, due to cost constraints and other factors, SDN is difficult to fully deploy. It has been proposed that SDN devices can be incrementally deployed in a traditional IP network, i.e., hybrid SDN, to provide partial SDN benefits. Studies have shown that better traffic engineering performance can be achieved by modifying the coverage and placement of SDN devices in hybrid SDN, because they can influence the behavior of legacy switches through certain strategies. However, it is difficult to develop and execute a traffic engineering strategy in hybrid SDN. This article proposes a routing algorithm to achieve approximate load balancing, which minimizes the maximum link utilization by using the optimal solution of linear programming and merging the minimum split traffic flows. A multipath forwarding mechanism under the same problem is designed to optimize transmission time. Experiments show that our algorithm has certain advantages in link utilization and transmission time compared to traditional distributed routing algorithms like OSPF and some hybrid SDN routing mechanisms. Furthermore, our algorithm can approximate the control effect of full SDN when the deployment rate of SDN devices is 40%.
