Bandwidth limiting on output is easy...just use the token bucket filter (the following caps TX bandwidth to 50 MBits/s and RX bandwidth to 20 MBits/s): tc qdisc add dev eth0 root tbf rate 50mbit latency 10ms burst 50kb tc qdisc add dev eth0 handle ffff: ingress tc filter add dev eth0 parent ffff: protocol ip prio 50 u32 match ip \ src 0/0 police rate 20mbit burst 20k drop flowid :1 For more realistic simulation, you may want to check into something like NetEm: http://linux-net.osdl.org/index.php/Netem http://developer.osdl.org/shemminger/netem/LCA2005_paper.pdf With netem you can add large (and variable) delays, random packet loss/duplication, out-of-order delivery, and various other 'real-world' conditions. - -- Charles Steinkuehler [EMAIL PROTECTED] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFEDghYLywbqEHdNFwRAuCJAJ0UP6BN2wRH8YJ0nsoogYtR0Z67+gCfbQ2+ wNkbsKnyDqIs0is09XO6/lE= =OB3Z -----END PGP SIGNATURE----- ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
