Alex,
DMM is not meant to be only about a bunch of MIP-based solutions.
There are various components in DMM solution space that'd also work with
GTP-based architectures.
For example, identifying the mobility needs of flows.
Or, conveying the mobility characteristic of a prefix to the UE.
Alper - thanks for the reply.
Identifying the mobility needs of flows assumes that IP flows _can_ be
characterized, and then distinguished as mobile - or non-mobile. I
think this is very hard to do, given the difficulty to write good
firewall rules, and the difficulty of analyzing traffic dumps.
For example, Netalyzr was written to tell whether or not one's computer
is connected to the Internet. That report page has so many lines that
it is hard to tell which part of it really means 'connected to the
Internet'.
The same problem may arise when trying to identify a particular 'flow'.

That is quite possible. Your comment on the list was "I am against any
deployment work before we decide on a solution..."
I read that as an objection to having the deployment models work item on
the agenda. Please do tell me what I am missing.

Hi,
I am following the discussion and me too I do not quite understand what is the
complain.
I am happy to learn that a if a WG is to be formed then it would be around a
solution rather than just requirements or architecture.
That said, I would like to express a worry along similar lines.
In DMM, precedents and the keen NETEXT, there seems to be a hard-rooted
disconnect between the product developped - (P)Mobile IP - and the deployments.
We know for a fact that 3GPP deployments (2G/3G/4G) do not use (P)Mobile IP.
We also know that 3GPP specs do mention Mobile IP. To such a point that I
wonder whether 3GPP has not the same disconnect as here.
On another hand, we do have indications of where (P)Mobile IP is used - the
trials, the projects, the kernel code, and not least the slideware attracting
real customers.
The worry: develop DMM protocol while continuing the disconnect.
Alex
