Gabor, thank you for recalling the http://tools.ietf.org/html/draft-hokelek-rlfap-01 Internet Draft that Telcordia submitted earlier.

All: While that earlier Internet Draft did not gain much traction within the Routing Area WG at the time of its submission, we continued to experiment with its methods and have published some proof-of-concept results.

I am glad to see that there is renewed interest in the general topic of expanding/formalizing protection against link failures beyond the basic LFA path mechanism (RFC 5286).

I will review the latest drafts on LFA technologies and look forward to collaborating where possible.

Thanks.

John

Wow... I will read it as soon as I can, I'm curious what is the difference between this and http://tools.ietf.org/html/draft-hokelek-rlfap-01 - first I thought that you're speaking about this one, since the title is very similar. At the last IETF we proposed this http://tools.ietf.org/html/draft-csaszar-ipfrr-fn-01, but it seemed that everybody was strongly against giving up local protection (like it was a religious dogma). It's good to see that I'm not alone anymore!
BR,

Gabor

Please find the following submission complementing the LFA technology:

http://www.ietf.org/id/draft-shand-remote-lfa-00.txt

It drastically extends the coverage of LFA while keeping its simplicity.

Cheers,
Clarence
