Implementation of service function chaining control plane through OpenFlow

This papers describes a proof-of-concept implementation of the Service Function Chaining Control Plane, exploiting the IETF Network Service Header approach. The proposed implementation combines the OpenFlow protocol to control and configure the network nodes and the NSH method to adapt the service requirements to the transport technology. The manuscript shows that the result of this combination is a very general architecture that may be used to implement any sort of Service Function Chain with great flexibility.
