When one of these NATs goes down, active connections will be
lost, but IGP routing will switch users automatically to a
different NAT when they retry.
If you allow your hosts to use multiple connection points into the
Internet, and external routing changes so that the packets they
send go out different connection points, their apparent source
address can change. One of the requirements for effective use of
NAT and multihoming is that your hosts' peers need to handle this
(via Multipath, HIP, MIP, SCTP or whatever). That is, you can't
allow your hosts to use multiple connection points until everyone
_else_ they talk to has been upgraded. How will you know when that
is?
A host knows if it is using HIP, MIP, or SCTP to communicate with
another host.
I was asking how the site knows when its hosts peers have been upgraded,
so that it can allow their traffic to be routed out multiple interfaces.
FYI, there is also a new idea for Mobile DTLS which
provides similar address mobility, draft-barrett-mobile-dtls-00.txt.
Yes but that should be a different thread.
