Hello Pierrick

First of all, thanks a lot for agree with the big picture depicture and architecture..
I am fine to split the architecture considerations and solution design in two different documents.
And I updated the architecture draft (No specific solution there) in the new version, I hope it makes sense for you.
http://www.ietf.org/internet-drafts/draft-lhwxz-hybrid-access-network-architecture-01.txt
Do you mind to share more about the solution about DMM proposal.
Which exact issues it is really solving?

Best Regards
Li

Hi Li,

Architecture considerations and solution design are two different things, which should not be addressed in the same I-D. People may agree with the big picture depicture and architecture but not agree with going on extensions to the GRE protocol to address the issue. BTW, I think that going for extensions to GRE header to address the hybrid access use-case is not the right way. Actually, IETF solutions already exist (RFC  4908 ) and, moreover, there is ongoing effort in DMM to update RFC 4908 to meet hybrid access requirements.

BR,
Pierrick

Hello



Thanks Barbara to send this liaison out.

Hybrid Access network is that Residential gateway (RG, or CPE) is extended with more than two access lines

(e.g. DSL + LTE) in order to provide higher bandwidth for the customers. The scenario and architecture are shown as follows

[cid:[e-mail]8CD480]



Right now, we have two individual drafts, one for architecture and requirements, and the other one is for an optional solution.

The draft (http://tools.ietf.org/html/draft-lhwxz-hybrid-access-network-architecture-00 ; ) proposes the architecture and gap analysis.

The solution draft proposes one option for the solutions, http://tools.ietf.org/html/draft-heileyli-gre-notifications-00

We did not combine them as one draft, because we believe there may be other candidates, and we would like to have further discussions in the related groups and IETF.

We used to present it in Homenet in Toronto.



Now the authors have invited Orange to join this architecture work. We will send out the new version of these drafts soon.

We are glad to invite the experts for comments.



Best Regards

Li Xue on the co-authors behalf

But some of the BBF effort may be focused on what can be done around "bonding" of multiple interfaces that are under the control of a single service provider. I don't see this in mif or homenet.



Thanks.   I couldn't really tell what was being proposed from the Liaison statement, so this information is helpful.
