1.  Introduction

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

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