This document defines the new architecture of BNG devices with control plane (CP) and user plane (UP) separation. BNG-CP is a user control management component while BNG-UP takes responsibility as the network edge and user policy implementation componenet. Both BNG-CP and BNG-UP are core components for fixed broadband services and deployed separately at different network layer in actual network.
