Hi, Acee.

 

We have the trial of BNG (not the BGP) in several provinces. Test around BNG basically classifies as follows. We can go detailed discussion if you are interested in it.


Functionality

Basic test considering BNG-CP


BNG access function


COA/DM function


QoS function


Performance

Dial rate of users on BNG-CP/BNG-UP


Maximum Sessions on BNG-CP /BNG-UP


Reliability

BNG-CP  failure


BNG-UP reload


HA of BNG-UP


Channel of BNG-CP and BNG-UP failure

Hi Gu, 

 

Have you implemented this BGP deployment model or is it still in the IETF draft and powerpoint phase? If it has been implemented, can you share any benchmarks? 

 

Acee

Hi, dear all.

 

Here we give a short introduction of CUSP design team research work. Recently CloudCO project on CU separation BNG device has been approved. Now WT-384 is now approved and officially TR-384. In TR-384, the CU-separated BNG architecture is provided with control plane (BNG-CP) and user plane (BNG-UP) separation. This new architecture brings several advantages such as centralized session management, flexible address allocation, and high scalability and cost-efficient redundancy and so on.

 

Besides the architecture, there are reserved work to be done with details. Here we present several related drafts.

(1) One is the "Information model of control plane and user plane separation BNG" which describes the information model of BNG-CP and BNG-UP in order to form the related data model.

 <https://www.ietf.org/internet-drafts/draft-cuspdt-rtgwg-cu-separation-infor-model-00.txt> https://www.ietf.org/internet-drafts/draft-cuspdt-rtgwg-cu-separation-infor-model-00.txt


(2) Another is "Deployment Model of Control Plane and User Plane Separated BNG" introducing the deployment of CU-Separation BNG.

 <https://www.ietf.org/internet-drafts/draft-cuspdt-rtgwg-cu-separation-bng-deployment-01.txt> https://www.ietf.org/internet-drafts/draft-cuspdt-rtgwg-cu-separation-bng-deployment-01.txt

 

(3) Besides the draft "Requirement for the protocol of the control plane and user planes separation BNG" involving the communication protocol requirement of BNG-CP and BNG-UP.

 <https://www.ietf.org/internet-drafts/draft-cuspdt-rtgwg-cusp-requirements-01.txt> https://www.ietf.org/internet-drafts/draft-cuspdt-rtgwg-cusp-requirements-01.txt

 

Any comments are welcomed.
