Proactive VNF Redeployment and Traffic Routing for modern telco networks

Redéploiement proactif des VNF et routage du trafic pour les réseaux télécoms modernes

Résumé

The last decade has witnessed the rise of Network Function Virtualization (NFV). Despite its benefits, resource allocation and traffic scheduling are still challenging. A practical issue is where to place Virtual Network Functions (VNFs) in the network to sustain long-term optimal objectives and when to reallocate resources given the dynamics of the substrate network. Most prior works either consider static settings or work in reactive fashions. This paper proposes a dual-window algorithm for proactive service redeployment and traffic routing. Specifically, our algorithm employs an entropy measure to gauge the uncertainty in the substrate network and cognitively updates the service redeployment interval to avoid unnecessary data collection overhead. Our algorithm is lightweight, intuitive, requires no offline training, and achieves the best overall effectiveness and efficiency compared with three state-of-the-art solutions.
