Another example of network having router in the core(CSCO) and 36170 at the edge is IXC's Gemini 2000.However management is done on ATM. The real story at core is who will deliver fast and reliable core router,which is capable to carry IP and ATM cells, with full compatibility with existing core networks as well as with ATM based core networks. My bet is on NN or/aND thier affiliate(s). So far their is no core router on the market with IP/ATM and large scaleability. Zbyslaw

Peppe --- I haven't had time to watch the market but did read a few posts and thought you might enjoy a couple articles on IP/ATM: jump.altavista.com Cover story, May 10, 1999: . . . . So far, though, IP doesn't appear to be a big player in the next generation networks. ATM is currently the protocol of choice, according to representatives from MCI WorldCom, Sprint and AT&T. When Sprint announced ION last June, rumors of IP were present, but CEO William Esrey struck that down. At Internet World last year, Esrey said, "We have chosen ATM, which fully supports IP, so that we can offer public-switched telephone voice quality now without losing the advantages offered by IP-based applications." But right after that statement, Esrey said, "Sprint is fully, completely committed to IP." So if IP is the protocol of the future, why are the IXCs calling on ATM for their next generation networks? "It has never been IP; it has always been ATM," says Ken McGee, an analyst with The Gartner Group. "It is part of the confusion factor to even compare IP with ATM. One is a protocol and the other is not a protocol per se, but a statistical multiplexing means to convey information."
