| At a certain point, some of these arguments about ATM efficiency sound a bit | like saying FDDI is terrible because 4B/5B encoding is | only 80% efficient. But FDDI has a *great* admission-control scheme. However, I almost concede your point. :) [*] | I think a more interesting measure of the value of ATM | versus other wide-area technologies is some sort of | measure of throughput per dollar. No kidding. Sean. P.S.: [*] almost, because in an application where one is using ATM as a single point-to-point PVC along a long-haul trunk that is to be used essentially exclusively for IP traffic, the cell tax seems really excessive. Given the movement towards cisco's packet-over-SONET, should that work and should others implement similar and preferably interoperable point-to-point interfaces, I will have to withdraw my almost-concession, except in cases where people _really_ want to do point-to-multipoint stuff.
