Rant

Cowards!!!

Last Friday, I wrote:
The next telco sales rep who tells me that we have to connect to them using ATM because they are selling a business grade product is going to get a punch in the snoot.
Today we have a winner.

But he did it via email.

Sneaky weasels, these sales reps.

But for crying out loud, it's 2006! ATM is a 1970's solution to a 1960's problem. The increases in speed of computer networking mean that the QoS features built into ATM are now effectively redundant, and at the same time, enormously expensive.

Just. Go. Away.

Dammit.

This Wikipedia article provides a good overview of the issues. What it comes down to is that I can get at least three times as much bandwidth over ethernet for the same price, even though I am buying the ethernet from one of the most expensive players and the ATM from one of the cheapest.

Update: Here's a Wired article from ten years ago explaining the problems, only with more personal details. Of course, it's Wired, so half of it is crap, but it's still useful for perspective.

Basically, it's another example of Worse is Better.

1 For a more technical perspective, here's something I consider essential for those reminiscing about 10 years ago:

One interesting point Mr. Antonov made was that the "isochnonous" transfers and "bandwidth reservation" was a fraud. I find it quite remarkable that anyone could figure that out back at the time. The state of the art for the Voice over IP was Van Jacobsen's "vat" program and LP2 codec. Of course now, everyone knows that Skype works that way, and it works better than actual telephone in many instances (betweeen U.S. and Russia, for example).

Another reason telcos want ATM is that they want "smart network" (with associated margins), whereas customers want "dumb network".
