Hi, I have set up sth very similar to the example "efcbq" in TC. Here is my network setup: [Host1]---------eth0[router]eth1----------[Host2] I send udp traffic from Host1 to Host2, passing thru router. I run the efcbq code on dev eth1. After that, i run "tc -s qdisc". For each of the class (pfifo for EF; red for BE), there are parameters "drop" and "overlimit". For the drop parameter, is it supposed to mean how many packets is drop by the class. Eg: if i limit EF to be 3Mbps, and i send 4Mbps, shouldn''t i supposed to see some number in the drop parameter? But i only see zero for the drop parameter. Another thing, for the paramter "sent 10000 packets" shown, does it mean that i should also receive 10000 packets in Host2? I have packet loss from router to Host2. So, in Host2 i do not get 10000 packets. Any advice? How do you guys graph in order to get statistics like delay and throughput? Which software, at the router or Host2 side? Thanks in advance. _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
