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.
