    Information Model of Control-Plane and User-Plane Separation BNG
            draft-cuspdt-rtgwg-cu-separation-infor-model-03

Abstract

   To improve network resource utilization and reduce operational
   expense, the Control-Plane and User-Plane separation concept is
   defined in Broadband Forum TR-384.  This document describes the
   information model for the interface between the Control-Plane (CP)
   and the User-Plane (UP) in the CP/UP separation BNG.  This
   information model may involve both the control channel interface and
   the configuration channel interface.  The interface for the control
   channel allows the Control-Plane to send flow tables to the User-
   Plane, such as user's information table, user's interface table, and
   user's QoS table.  And it also allows the User-Plane to report
   resource and statistics information to the Control-Plane.  The
   interface for the configuration channel is in charge of the protocol
   version negotiation between the Control-Plane and User-Plane, the
   configuration for devices of the Control-Plane and User-Plane, and
   the reports of User-Plane's capabilities, etc.  The information model
   defined in this document supports defining a standardized data model.
   Such a data model can be used to specify an interface to the CU
   separation BNG.
