Thanks for the comments.
Want to clarify that "draft-ietf-trill-directory-framework" is only intended to describe the benefits of directory assistance for TRILL network and the high level stuff (e.g. basic Pull/Push models). The draft is not intended for describing the detailed mechanism.

The mechanism which we discussed last week is described in "draft-dunbar-trill-scheme-for-directory-assist" (which is still a personal draft).

I think it is necessary to have the framework document so that we don't have to justify why directory assistance is needed for TRILL. We already spent 3 IETF meeting cycles to justify why we need directory assistance. It will be more productive to separate justification from the mechanisms, so the discussion can be focused.

As for describing policy (or ACL in your email), we discussed to add as responses to Pull request to the detailed mechanism. I can add a simple statement in the framework to indicate that Policy can be added and leave the details to the mechanism draft.

I've never been fond of "framework" documents, but this is fine for describing the problem.  If it's supposed to be complete in some sense (whatever that means for a "framework"), it's missing some things that people suggested last week, e.g., the ability to be informed of an ACL policy, to make, e.g., a hypervisor have an endnode table that has (IP address, MAC address, TRILL switch address, only allowed from this set of MAC addresses).

And there might be other information we'd want pushed or pulled, e.g., IPv4 and IPv6 address.

Is it clear that the framework document doesn't preclude these extra things even though I don't think they are in the draft?

Do we really need a framework document instead of just a single WG document on formats and algorithms that perhaps has a few paragraphs to explain why a directory is useful?

We would really like to she some more explicit indications from WG participants that they have read this document and agree with it.

Please include any substantial as well as editorial improvements that result from reviewing the document.
