Hello Xueli,
Several people look at this problem as an IP problem. Instead of
considering a cellular+dsl combination in a homebox, they considered
cellular+wifi on a smartphone. But the goal was the same: augment the
bandwidth perceived by the end user.
In implementation it is however quite challenging. The more tempting
the expectations of augmenting bandwidth by simply adding network
interfaces (as in adding RAM to a busy computer), the higher the
desillusion when facing the challenges of implementation.
Some consider it simply as a local computer policy problem (and hence no
new communicaiton standards needed), but others consider that there is a
need of a server in the infrastructure to which these interfaces would
first connect (a sort of an 'anchor').
If such a technology is developped, it will surely be useful for more
than homenets - it will be useful for multi-interfaced smartphones,
useful for mobile routers installed in vehicles, and more that I can not
think of.
Alex
PS: there are a few IETF Internet Drafts about how would smartphones
would use this, with Mobile IPv4 and Mobile IPv6 extensions, but there
are no widespread implementations.

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:image002.jpg@01CF9A07.BF8CD480
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

FYI. I made sure they were aware of IETF mif and homenet activities
in this area. I intend to try to prevent having to track efforts
that try to do the same thing in two different ways. 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.
