Joe,
What I got from UUNet and the VP of our company was that it was delivered over a 10Mbps ATM circuit, into the Net Edge, then out via 10Mbps ethernet. We've asked for a better handoff, and they refuse to deliver it.
Having (briefly) alpha trialed a 10Mbps ATM / Netedge service on an MFS Worldcom ATM service, I can state conclusively state that this will *not* run well. In tests we managed to get a maximum of (from memory) 3.4Mb/s (running both directions simulatenously) through the service without it starting to drop packets. You need a decent bursty load simulator to really hit it, but the Net Edge buffers were a real problem. A memory upgrade on the NetEdge and them reworking the config helped, but not much. Our solution was to remove the NetEdge each end and plug straight into a Cisco AIP. Unsuprisingly this worked far better (though even that has its problems). [Those having religious objections to ATM, please excersize pluralistic tolerance by not bothering to repeat your objections just now :-) ] Are they implying that you can get 10Mb/s through this service without losing packets? (even unidirectionally). I would be interested to see this demonstrated with a traffic profile which would sit quite happilly on a 10Mb clocked serial port (or 10/45s of a DS-3 traffic or whatever).
