That's funny to hear from somebody from Ipsilon :) Granted, ATM as is is quite useless. I have serious doubts that it can be made useful at all (as anything but a stupid framing protocol). The router capacity is not the only problem, there's also the long-haul capacity problem. Yes, fibers are not ribbon, and you can put only as many bits in them. So the current games with ATM (throw away 30% of user data capacity) and dual-ring SONET (throw away another 50%) as opposed to native packet switching is not even a silliness, it's plain old stupidity. >And I would suggest that if you were, say, a big phone company, and you >actually understood... You gotta be kidding. The whole corporate culture in telcos is built around single-digit growth rates, when next year's provisioning is done by tweaking previous year's figures, and being a droid is rewarded, while doing something new is regarded as pain in the neck. >So we've got routing problems front and center, here and there, with >bandwidth problems creeping up behind.

Tried to find venture capital for a backbone router company recently? On reasonable terms? There is hardware which physically can route *terabits per second*. It is there. It is real wires and real silicon, not fancy projects. The problem is that there are very few people with a clue on how to make the router software for the boxes, and the management is intent on blessing Americans by saving them trip to the next corner's Blockbuster.

No. The screaming about traffic explosion was high for the last few years, and it generally fell on deaf ears. There's a perception among those who has the money that ATM will come and fix everything by magic, so there's no point in building routers. Maybe that's our fault that we allowed the charlatans to push their snake oil to those who don't know better. My personal course in that is to keep playing with my toys and wait till the fun begins. Shouldn't be long. The worse, the better. --vadim (NOT a Sprint employee, just using old mailbox).
