The authors propose a new approach to MPLS that uses the standard MPLS data plane and an OpenFlow based simpler and extensible control plane. They demonstrate this approach using a prototype system for MPLS Traffic Engineering. MPLS has evolved over 15 years as a solution for ISPs. It is primarily used to perform traffic engineering in IP networks and for offering MPLS based L2 or L3 enterprise VPN services. Providers require traffic engineering for effective use of their network infrastructure, and enterprise VPNs continue to represent one of their most profitable service offerings.
