RE: [Mip4] Request to consider FMIPv4 as a working group document

[Narayanan Vidya-CVN065 <vidya at motorola.com>]

All,
Does anyone know what happened to the draft on post-MIT? A few years ago, I thought it was being considered to be part of the low latency handoff spec - but, obviously it has not made it. 

James' draft on Post-MIT was trying to solve the issue of L2 dependency. Essentially, I see this as a major deployment issue to have a fast handoff solution exclusively dependent on receiving an L2 trigger (e.g. the L2 Target Trigger at the nFA). 

I think an approach like FMIPv4 is essential in light of this. Ideally, I think post-MIT should have been a part of LLH - that way, we won't have the need to have 2 specifications that are somewhat close with only minor differences.

Hi Charlie

I support making this draft a WG item.

I do have some concerns that more or less reflect what Kent Leung has voiced in previous mails on the list. 
- AR == FA 
- IP address management

An additional issue is how the MN-PAR auth extension is handled. I take it this will reuse MN-FA auth extension. It will require key distribution of some kind that could jeopardize the performance benefits. What am I missing?
