Technical Summary

   Instead of considering a single SFC control plane that can manage 
   complete service paths from one end of the network
   to the other, the document adopts an approach that decomposes 
   large networks into smaller domains operated
   by as many SFC sub-domains (under the same administrative entity). 

   This approach is called: Hierarchical Service Function Chaining (hSFC)

   The goals of hSFC are to make a large-scale network easier to reason
   about, simpler to control and to support independent functional
   groups within large network operators.

Working Group Summary

   Two WGLCs were made for this document. The second one was mainly to confirm that the comments
