Xiaohu,
I don't see how you arrived at your first assertion. There may
be other ways to accomplish
virtualized networks (address-space segregation might be one, for example) but
the basic choice is
either hierarchical (what we are referring to as "overlay") or flat.
In a flat network, unless you work out a standard way to
segregate broadcast/multicast
traffic, you will see it everywhere. Even if you do work out ways to segregate
it (a similar address
segregation might be applied to multicast traffic, but at some high cost), you
will see this traffic in
more places than you should, simply because some links will have more than on
interest-group's
traffic.
On the second assertion, I believe we've had this discussion
before and it would be just
a bit of unnecessary churn moving this text around at this point.

Hi all,
The current version looks fine. I just have some minor comments as follows:
1. In section 6, it said
“
It is believed that overlay-based approaches may be able to reduce
the overall amount of flooding and other multicast and broadcast
related traffic (e.g, ARP and ND) currently experienced within
current data centers with a large flat L2 network. Further analysis
is needed to characterize expected improvements.
”
IMHO, the above statement is not correct since this is irrelevant to whether
the virtualized network is overlay-based or not.
2. It seems that this problem statement draft did some additional work
which the framework and the requirement drafts should do. For example, it
talks about the three possible work areas in the control plane, would it be
better to move this part to the framework and control-plane-requirement docs?
Best regards,
Xiaohu
