    abstract =  {As described in {[}I.D-boucadair-sfc-framework{]}, the dynamic enforcement of a Service-derived, adequate forwarding policy for packets entering a network that supports such advanced Service Functions has become a key challenge for operators and service providers. This document is based on {[}I.D-boucadair-sfc-framework{]} and discusses how the Service Functions chain is structured and how Service Function Chaining path is provisioned and setup.},
