Hi Folks,
In the interim meeting, there were much discussion on the BNG deployment in the home broadband scenario. In the section 5 of the following draft, there is more details about the scenarios.

As far as I know, there are types of deployment of BNGs in the scenarios:
1. RG is directly connected with the BNG
2. RG is connected spanning the metro network.
Because the BNG is responsible for the user management, if failure happens, it will have much negative effect on the users’ access to the Internet or other network services. If the second deployment method is used, the number of the BNG is small and the BNG can access more users, but the risk is high. If the first deployment is adopted, it may need more BNGs, but the risk can be low. So there is the trade-off in the network design and the deployment of the BNG.

The draft takes the second deployment to illustrate that the QinQ information besides the 5-tuple information can also be mapped to APN ID when the packet traverses the metro network.  That is the reason why not describe the first type of deployment.

Dear all,

The APN Interim meeting has been scheduled on June 3rd. Please find the meeting information shared by the Chairs of the RTG WG below.

In this APN Interim meeting, we are going to focus more on the discussions of the solutions (more overview than details), including
1.       the design of the APN attribute itself
2.       the encapsulation of the APN attribute on the various data planes (the encapsulation on the IPv6 data plane is an example)
3.       the control plane protocols extensions for exchanging the APN attribute
4.       NETCONF/YANG models for the NBI and SBI

You are very welcomed to join the discussions, and your comments and suggestions are very much appreciated.

Thank you!
