But I don't think it's going to happen since ATM can be used in too many different ways (e.g., Classical IP, leased lines, MPLS). If we have to choose one, it will be HARP but we do not need to. It seems that the two drivers have different segments of the ATM users. Network research people tend to choose Cranor's driver to play with since it's simpler and they don't need Classical IP or SVCs. So, I personally want to keep Cranor's driver as long as there are interests. On the other hand, I think "netnatm" directory could be removed. It's a quick hack, it's kind of messy to have both "netnatm" and "netatm" directories under "sys", and I don't know many people using it. At least, the following items are supported in Cranor's driver but missing in HARP: - Adaptec card support although Adaptec has dropped ATM NICs from their product line, Adaptec cards perform much better than ENI cards. - BPF support - shaper support crucial to a wide area ATM services quite convenient as a variable rate link for testing - multicast support if the interface is configured as a point-to-point interface - IPv6 support we all know it's comming And, at least, the following groups, each has a considerable amount of users, are using Cranor's driver: - ALTQ - KAME/INRIA IPv6 - CAIRN - netbsd/openbsd - WIDE --Kenjiro To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-atm" in the body of the message
