Hi -
This morning I received a telephone call from Jason Cook
from an organization called ACM. His organization is attempting
to sign people up for an IETF course in IPv6 taught Dr Charles Alexi,
who apparently is a senior member of the IETF.
Apparently Mr Cook was told that these courses

Ugh. Ick. You're not wrong, of course, but just ... "Yecchh."

Following on from the success of ISSE 99 EEMA and TeleTrusT invite you to
participate in the call for papers for ISSE 2000. We would very much
appreciate if you could pass this information on to interested parties.
Please apologise for multiple receipt.

Carrier species and circannual timing will be critical issues here.

Ah, BGP.
Ok, so it seems like there is a 1-1 mapping of TLAs to AS numbers --
after all, why would an AS encompass more than one TLA prefix?

in reality, with the current ipv6 allocation policy of the registries, all
asns are using the same single tla. it's one of those theory and practice
things.

This is definitely a research issue. I think however that there are at
least three possible solutions, and so I believe that this is not a very
difficult research issue.

it also assumes that 'performance' is a one-dimensional quantity.

Hi robert,
I really loved the critique on this draft. Can I use these comments in the
draft for the second version ? Would you be willing to co-author this ?
Please let me know.
thanks,
