A novel approach for improving MPLS VPN security by adopting the software defined network paradigm

Abstract The security of network infrastructures is one of the tedious tasks in modern networks. Indeed, nowadays’ demanded security must have as a characteristic the dynamism and the capacity to adapt to the context of the exchanges, in other words, security must not influence network performance. To meet this need, network automation through a software-defined network (SDN) controller can be used. SDN a new paradigm, allowing through a controller to orchestrate the entire network architecture. In this paper we propose a new solution for the dynamic generation of security policies between different MPLS VPN sites by adopting the SDN approach.
