Implementing NFV routers and SDN controllers in MPLS architecture

In the MPLS architecture, there is a strong argument to virtualize network functions ahead of implementing SDN. Because it is a relatively new investment, the MPLS represents an opportunity to create a foundation architecture that will scale over. Moreover, there are two other closely linked in networking occurring in the same time NFV and SDN who can deliver benefits to the MPLS backbone and edge switching routers which increase network component's flexibility, scalability and reliability.
