Dear WG,

From last ietf meeting, the CU separation BNG have call more attention, many operators and vendors show their interesting and join the discussion.
Thus, we update the CU separation BNG information model.

In this version, we specifies the information model in Routing Backus-Naur Form.
And add a section to introduce the usage of CU separation.
We also rewritten some text to improve the draft’s readability.
Finally, some new authors join us. Thanks Victor and Shujun’s input and valuable comments.

More details please see the document, the links are shown below, suggestions and comments are welcome!

Best Regards!
-Michael

A new version of I-D, draft-wcg-i2rs-cu-separation-infor-model-02.txt
has been successfully submitted by Michael Wang and posted to the IETF repository.

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

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.

Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
