RE: ATM

EOL?  What do you mean EOL?  Come Again?  What you say? Phone companies
EOL stuff? ;-)  

Just because it's not EOL, doesn't mean you can't do better either.
Rather than saying "I want this type of MAC" technology and posting it
(as a troll) to a forum concerned primarily with IP operations, one
should probably step back and worry about what you're trying to
accomplish.

Mentioning ATM (and saying you want it for IP QoS) on NANOG is in my
book much like screaming "Fire!" or "Free beer!" in a crowded place. ;)
Ah, nice to see how the NANOG Chain(TM) can still be yanked quite
easily. ;)..

Define the problem you're trying to solve.  Assess the tool chest.
Implement.  Observe.  Rinse.  Repeat.

Best regards,
Christian
