I'm using dummpnet+pf (not ipfw) on (roughly) FreeBSD 7.2 quite extensively for traffic shaping. I have about 20 pipes varying from 600kbps to 100Mbps all with ~9msec delay. There's a background load of at least 10Mbps with peaks to several times that (and several 2Mbps pipes are virtually permanently saturated). The system has nearly 80 VLANs and uses CARP and lagg/LACP (1 bge and 1 em NIC) for redundancy. The system has an uptime of several months. I haven't responded before because I can't offer any solutions. All I can say is that I've been successfully using dummynet with ipfw or pf for about a decade without any stability issues. --=20 Peter Jeremy --WIyZ46R2i8wDzkSu Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.15 (FreeBSD) iEYEARECAAYFAk1iBFkACgkQ/opHv/APuIe8FgCgwLaCw6x/lVQE+huwihvGlcpb ED8AoLV9lXQhR69nr5EWgqilDfiAjokm =3fE5 -----END PGP SIGNATURE----- --WIyZ46R2i8wDzkSu--
