[Seamoby] CAR Discovery Draft

Hesham,

OK, this sounds like some comments on
draft-ietf-seamoby-cardiscovery-issues-01.txt.

It certainly would have been helpful if you had posted your comments
during the Last Call period.
Last Call expired Jan. 4 on this document. I don't believe comments sent
in after
Last Call necessarily need to be accommodated, but, if these are simple
editorial changes that can be
 resolved in the next day or two, then I think we can accommodate them.
However, I do not want to get into a
 long discussion about requirements prior to releasing the problem
statement. If we can't resolve these
editorial issues by Tuesday, the draft will go to the IESG as it
currently stands.

Here are some suggestions about changes in the wording.

How about:

    In this approach, an AR currently serving the MN identifies some set
of
    suitable CARs for the MN's handoff, at some point prior to handoff.

If this text is unsatisfactory, please feel free to propose an
alternative.

One of the problems with not having a consistent set
of terminology for wireless networking in the IETF
is that it becomes difficult to find a word that describes
the concept you are trying to get at without impinging
on what somebody else thinks a particular word
means. I believe this is the case here. The "anticipated"
here has nothing to do with "anticipated handover."
Here, the AR is anticipating the need for CARs
by performing discovery prior to the MN needing
them. The anticipation is exactly the same anticipation
as occurs for distribution of routing information prior
to a packet arriving at a router that requires that
routing information.

Perhaps another word would be suitable? Please
feel free to suggest one. Perhaps "router based"?
