Abstract
Multi-Protocol Label Switching VPN (MPLS-VPN) is a technology for connecting multiple remote sites across the operator’s private infrastructure. MPLS VPN offers advantages that traditional solutions cannot guarantee, in terms of security and quality of service. However, this technology is becoming more prevalent among businesses, banks or even public institutions. With this strong trend, the management of the paths on which these tunnels can be deployed has become a necessity is a priority need for Internet access providers (ISPs). Through the principle of controller orchestration, ISPs can overcome this difficulty. Software-defined network is a paradigm allowing through the principle of orchestration to manage the entire network infrastructure. In this paper, we propose a new approach called FNA-TE "Flexible Network Adaptive - Traffic Engineering", this approach allows to manage MPLS VPN tunnels to meet the QoS requirements of those with the highest priority.
Highlights
Multi-Protocol Label Switching "MPLS" is a transfer protocol that uses tags for routing data [1][2]
MPLS-traffic engineering (TE) creates a connected mode in IP net-works, optimizing the use of resources and maximizing the traffic load that can flow over the network while preserving the quality of service
The control layer can act on the path on which to deploy MPLS VPN tunnels based on the available bandwidth and the shortest route
Summary
Multi-Protocol Label Switching "MPLS" is a transfer protocol that uses tags for routing data [1][2]. This technology brings more flexibility, speed, and security compared to the Internet Protocol "IP". Among the strengths of the MPLS technology, traffic engineering (TE) is used to optimize the use of network resources to avoid congestion. It is the consideration of the bandwidth avail-able on a link during routing decisions that makes this optimization possible.
