It is well maintained. As far as its usability, the HARP driver has no IP QoS support that I know of. Thus making it unsable for my work. > >> I am aware that many reseach projects run on Cranors stuff, but if > >> they are not even considering upgrading from FreeBSD 2.1 for > >> instance, they do not really factor into the equation of FreeBSD > >> 3.1 and further down the road, do they ? :-) > > They do.

When EOS is fully operational in 5 years it will be pumping data at an average of ~200Mbs. The ALTQ prototype is reliable and robust at handling traffic at OC-3 line speed. It has advanced QoS capabilities that are beyond the commercial implementations. If ALTQ will be incorporated into the FreeBSD tree then by default the Cranor driver will also need to be supported. I agree with Suresh Bhogavilli that there are features in the CAIRN version and ALTQ version of the Cranor driver that if merged would make an even better ATM driver. > --Kenjiro > George Uhl To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-atm" in the body of the message
