Sorry, gotta weigh in here...
As great as POS is, and as exciting as running IP on optical OC-48 onto WDM
gear sounds (no piece of cake, believe me...), there is STILL room for
ATM. More than just the much-touted network traffic engineering value, too.
Simply put, because of the B-ISDN heritage of ATM, I can actually run
synchronous circuits over it (using circuit emulation) and have it work right.
Can't get there from here with any IP-over-glass solutions, alas.
And as much as an "IP over everything" bigot as I've been for the last
17 years or so, I still run into situations where what I *HAVE* to
have is some kind of synchronous circuit. Wish it weren't so, but I can't
just tell people "oh, you can't do that"...
