    abstract =  {IP networks rely more and more on the combination of advanced functions (besides the basic routing and forwarding functions) for the delivery of added value services. This document defines a framework to enforce Service Function Chaining (SFC) with minimum requirements on the underlying network. The proposed framework allows for Differentiated Forwarding (DiffForward): packets are initially classified and marked at the entry point of an SFC-enabled domain, and are then forwarded on a per SF Map Index basis.},
