OpenFlow est une implémentation largement adoptée de l'architecture Software-Defined Networking (SDN). Les systèmes de surveillance de réseau conventionnels étant incapables de gérer les réseaux OpenFlow, les chercheurs ont développé divers systèmes de surveillance adaptés aux réseaux OpenFlow. Cependant, ces systèmes existants s'appuient soit sur un cadre de contrôleur spécifique, soit sur une API, qui ne font pas partie de la spécification OpenFlow, et limitent ainsi leur applicabilité. Cet article propose un système de surveillance transparent et à faible surcharge pour les réseaux OpenFlow, appelé Opimon. Opimon surveille la topologie du réseau, les statistiques des commutateurs et les tables de flux dans un réseau OpenFlow et visualise le résultat via une interface Web en temps réel. Opimon surveille un réseau en interposant un proxy entre le contrôleur et les commutateurs et en interceptant chaque message OpenFlow échangé. Cette conception permet à Opimon d'être compatible avec n'importe quel commutateur ou contrôleur OpenFlow. Nous avons testé les fonctionnalités d'Opimon sur un réseau virtuel construit à l'aide de Mininet et d'un banc d'essai international OpenFlow à grande échelle (PRAGMA-ENT). De plus, nous avons mesuré la surcharge de performances induite par Opimon et démontré que la surcharge en termes de latence et de débit était inférieure à 3 % et 5 %, respectivement.

Abstract: OpenFlow is a widely adopted implementation of the Software-Defined Networking (SDN) architecture. Since conventional network monitoring systems are unable to cope with OpenFlow networks, researchers have developed various monitoring systems tailored for OpenFlow networks. However, these existing systems either rely on a specific controller framework or an API, both of which are not part of the OpenFlow specification, and thus limit their applicability. This article proposes a transparent and low-overhead monitoring system for OpenFlow networks, referred to as Opimon. Opimon monitors the network topology, switch statistics, and flow tables in an OpenFlow network and visualizes the result through a web interface in real-time. Opimon monitors a network by interposing a proxy between the controller and switches and intercepting every OpenFlow message exchanged. This design allows Opimon to be compatible with any OpenFlow switch or controller. We tested the functionalities of Opimon on a virtual network built using Mininet and a large-scale international OpenFlow testbed (PRAGMA-ENT). Furthermore, we measured the performance overhead incurred by Opimon and demonstrated that the overhead in terms of latency and throughput was less than 3% and 5%, respectively.
