Validation of the NFV SDN Solution for the Efficient Management of MPLS Infrastructures

Abstract

Network virtualization consists of creating tunnels in the existing infrastructure and using a per-flow service. Network function virtualization allows the virtualization of "NFV" network functions from Layer 4 to Layer 7 of the OSI model, and thus NFV allows the creation of virtual functions in the network such as firewalls, intrusion detection and prevention systems, routers. Software-Defined Network " SDN " makes the network programmable and therefore allows a separation of the control plane from the data plane. In this paper we will validate our previously published solution for managing Multi-Protocol Label Switching "MPLS" networks based on an SDN NFV approach. The implementation has been performed in a real environment, the results obtained have shown the efficiency of our approach compared to classical solutions and SDN-only based solutions.
