              Control-Plane and User-Plane Separation BNG
                    Simple Control Channel Protocol
          draft-cuspdt-rtgwg-cu-separation-bng-protocol-04.txt

Abstract

   This document specifies the Simple Control Plane (CP) and User Plane
   (UP) Separation Broadband Network Gateway (BNG) control channel
   Protocol (S-CUSP) for communications between a CP and a UP. S-CUSP is
   designed to be flexible and extensible so as to easily allow for the
   addition of further messages and data items, should requirements be
   expressed in the future.
