Hi All, 

/Support

Authors, really interested in seeing more results from your test networks,
things like:

- Scalability of TTZ (network sizes)
- Start-up time, average time to form relationships, etc.
- Impact from link failures and convergence time
- Operational findings/issues 

Your I-D contains already contains some high-level implementation details
(Good Job!), but I suggest you report your existing/future findings as per
RFC6982 (Improving Awareness of Running Code: The Implementation Status
Section). This would include some or all of the following information: 

- The organization responsible for the implementation, if any
- The implementation's name and/or a link to a web page describing the
implementation
- A brief/general description
- The implementation's level of maturity: research, prototype, alpha, beta,
production, widely used, etc.
- Coverage: which parts of the protocol specification are implemented and
which versions of the Internet-Draft were implemented.
- Licensing: the terms under which the implementation can be used. For
example: proprietary, royalty licensing, freely distributable with
acknowledgement (BSD style), freely distributable with requirement to
redistribute source (General Public License (GPL) style), and other
(specify)
- Implementation experience: any useful information the implementers want to
share with the community
- Contact information: ideally a person's name and email address, but
possibly just a URL or mailing list

Finally, I would like to understand the applicability/impact when using
OSPF-TE. I guess this will be a separate document though.

BR, Dan.
