So far I see people stepping up > for HARP and ngATM, so just curious to hear from those netnatm folks. back in the late 90s, networking research people needed the cranor driver for 2 reasons. (1) IPv6: HARP internally has code specific to IPv4 and wasn't easy to use for IPv6-ready networks. (2) returning ENOBUFS on buffer overflow: HARP silently discards packets when the device buffer becomes full. backpressure by ENOBUFS to the upper layers was critical to the performance under heavy load. I don't know how many people are still using the cranor driver since the supported ATM NICs are not available on the market and ATM isn't so popular in the networking research community these days. -Kenjiro To Unsubscribe: send mail to [email protected] with "unsubscribe freebsd-atm" in the body of the message
