Hi Behcet,

Sorry for my late response.

As I looked over your dmm-for-wifi draft, I found two protocols to be used
to separate
control and data plane such as XMPP and OpenFlow.

It seems like you want to work on that protocols to be implemented in data
plane nodes.
OpenFlow is another forum controlled protocol so I don't touch it in the
IETF.
XMPP sounds nice. If you adopt XMPP with same model of
draft-ietf-l3vpn-end-system,
it almost same with using BGP like the vEPC draft.

But what I mentioned FPCP in vEPC is as a way to export mobility info to
BGP speaker
from control-plane nodes of mobility management.

And more, many parameters should be aligned for these nodes to utilizing
data-plane
network so that the config data model should also be defined in FPCP. I
think that's not
part of signaling protocol roles.

Thought?

Regards,
