1.  Introduction

   The main idea of BNG Control-Plane and User-Plane separation is to
   extract and centralize the user management functions of multiple BNG
   devices, forming an unified and centralized control plane (CP), while
   the traditional router's Control Plane and forwarding plane are both
   preserved on BNG devices in the form of a user plane (UP).We name the
   control-Plane and User-plane separation BNG as vBNG.

   The architecture of Control-plane and user-plane separated BNG is
   shown as the following figure.
