Steinar Haug says: > I haven't seen any sign of inexpensive 155 Mbps ATM NICs, why do you > think inexpensive 622 Mbps ones are coming soon? they are coming down in price, but not nearly low enough to be mainstream. the cheapest cards are the ones that use host memory for packet segmentation and re-assembly. I wish I had a performance study to see how much speed is lost using host memory for SAR operations.

ATM, lost that window of opportunity and today is not the fastest thing on the market because everone wants IP. I think even Sonet PPP/frame relay will upstage ATM. yeah, this prob. belongs in -chat or -atm. --mark.
