Hi Brian, Unless you correct me, I'll take this to mean that you oppose rejecting both strategy A and B. > But it is my opinion that B is a lost cause for IPv4. It is and it isn't. If you fix the layer 4/5 problem where the locator gets mixed in with the session ID, why should the resulting protocol not be layer-3 agnostic? You just put both protocol and locator in the guid to locator map instead of just putting a locator there. Presto! Done. Such a strategy-B protocol should be able to run on any layer-3 protocol available, which means it should coexist happily with the IPv4 backbone for as long a transition period as necessary. So in that sense, it isn't a lost cause for IPv4. Quite the contrary, IPv4 is part of the deployment bridge. But you're correct that there's no headroom for growth in IPv4. In that respect, strategy B is a lost cause for IPv4. But then ultimately, so is strategy A. > If someone can write > a proposal that proves that wrong, I'd be delighted. Feel free to take a look at the *very* early and *very* rough work at http://bill.herrin.us/network/name/name.html, especially snrp and ltp. I don't think it proves that IPv4 isn't a lost cause, but it does show how a strategy-B system can be layer-3 agnostic. >> Name three such applications.

Would it surprise you to learn that while "42" is the answer to life, the universe and everything, it is in fact not the answer to the multihoming problem? RFC 3484 addresses a problem that a complete multihoming solution might or might not run in to. Standing alone, RFC 3484 does not address the multihoming problem in any way shape or form. > So I think you can make your own list. Indeed I can. It contains zero items.
