Some points about Hierarchical HITs.
The idea is not new. See draft-moskowitz-hip-04 from 7/01. One bit was
used to identity Hierarchical HITs (HHITs) over flat HITs.
Since this concept was removed I am now faced with how to tell the
difference in the HIT encoding?
HHITs use a different ORCHID construction. Kind of violation the ORCHID
rules. Remains to be seen if it will take a direct addendum to ORCHID
for this. The HID is included with the HI in computing the ORCHID. I
often wondered if the HIT Suite should have been included. Since it
wasn't we do have to be careful in specifying HIT Suites so it is not
possible to have identical BIT-level HIs for different HIT Suites. I am
not attempting to change this part; maybe I should.
So given a HIT in the wild (I1, or UAS RID broadcast), how do you know
if it is a HHIT. Instead of burning through HIT suites as I first
thought in draft-moskowitz-hierarchical-hip, I am specifying a unique
HIT prefix for HHITs.
If anyone can see any other way, please speak up. Again, the ORCHID
prefix is specified in the ORCHID RFC. Will we best do an update to ORCHID?
Please chime in.

Hello all.
Finally we are now funded to work on this project. I am very unhappy
at what it took to get to this point. Fortunately, I have been using
the time to put together some notes that I am quickly turning into drafts.
So work on tm-rid is now open. Two more drafts will be posted in the
next couple days. I welcome reviews and comments.
Also I will be working with the AD for time at IETF106.

Abstract:
This document describes using a hierarchical HIT to facilitate large
deployments of managed devices. Hierarchical HITs differ from HIPv2
flat HITs by only using 64 bits for mapping the Host Identity,
freeing 32 bits to bind in a hierarchy of Registering Entities that
provide services to the consumers of hierarchical HITs.
Please note that it may take a couple of minutes from the time of
submission
until the htmlized version and diff are available at tools.ietf.org.
