    Information Model of Control-Plane and User-Plane separation BNG
              draft-wcg-i2rs-cu-separation-infor-model-02

Abstract

   To improve network resource utilization and reduce the operation
   expense, the Control-Plane and User-Plane separation conception is
   raised [I-D.gu-nfvrg-cloud-bng-architecture].  This document
   describes the information model for the interface between Control-
   Plane and User-Plane separation BNG.  This information model may
   involve both control channel interface and configuration channel
   interface.  The interface for control channel allows the Control-
   Plane to send several flow tables to the User-Plane, such as user's
   information table, user's interface table, and user's QoS table, etc.
   And it also allows the User-Plane to report the resources and
   statistics information to the Control-Plane.  The interface for
   configuration channel is in charge of the version negotiation of
   protocols between the Control-Plane and User-Plane, the configuration
   for devices of Control-Plane and User-Plane, and the reports of User-
   Plane's capabilities, etc.  The information model defined in this
   document enables defining a standardized data model.  Such a data
   model can be used to define an interface to the CU separation BNG.
