  Control-Plane and User-Plane separation BNG control channel Protocol
            draft-cuspdt-rtgwg-cu-separation-bng-protocol-02

Abstract

   This document specifies the CU Separation BNG control channel
   Protocol (CUSP) for communications between a Control Plane (CP) and a
   set of User Planes (UPs).  CUSP is designed to be flexible and
   extensible so as to easily allow for the addition of further messages
   and objects, should further requirements be expressed in the future.
