Well, I guess, this is the price we must pay for having a monoculture (a Cisco-powered) internet. If the single source of routers, switches and network components (speak: Cisco) makes a single mistake in a release version of their software (speak: drop ECN frames), everyone suffers. Cisco: If I buy a _new_ PIIX oder LDIR today, do I get an ECN capable IOS or not? If not, will my CCNA know about this and upgrade my Box before deploying? Everyone I know and their brothers, that use Cisco Equipment, have a support contract with Cisco. Why not push an "mandatory upgrade" along this path once the ECN leaves "experimental" status. But I definitely agree with HPA, that forcing ECN in its current state on all users is unacceptable. Solution that I see: DaveM at RedHat ships Kernels with ECN enabled per default. RedHat ships Distributions with net.ipv4.ip_ecn = 0 in /etc/sysctl.conf Ah, the small bliss of diversity... ;-) (And this means not, running both flavors of Linux, Debian _and_ RedHat... ;-) ) Regards Henning -- Dipl.-Inf.
