> 2- how commonly is IP over ATM used?
From the ATM Forum Board of Directors Report - Rome, Italy, April 23,1999:
... Fred [Baker, chair of the IETF] stated that 75% of all Internet traffic
today touches an ATM device and acknowledged the importance of the role
of ATM in providing traffic engineering in today's networks. ...
I don't really know where this number comes from nor whether it is
A number of facilities-based carriers are either migrating or talking
about migrating from ATM to some sort of IP-over-fiber solution. I
believe that the economics of ATM versus IP-over-fiber solutions are
tremendously different for those who own fiber compared to those who
don't own the fiber.
> Do network operators really care about the cell-tax?
Define "care". Certainly, one sees a lot of whining about the ATM
"cell tax". On the other hand, if Fred Baker is correct, ATM is heavily
used in the Internet. Having said that, I believe that any ISP that
selects a service on the basis of some sort of overhead measurement, rather
than an evaluation of cost versus performance, is confused.
