Hello, I'm using Linux kernel 2.6.x and tc (from iproute2 package). I'm trying to use HTB or HFSC scheduler in order to limite the rate of outgoing packets and also in order to minimiez delay for RTP stream. But I didn't suceed in having this 2 QoS services working. I use Iptables in order to classify packets. Here is my HFSC conf. In fact the pings that i send from this box should be the most highly priorised packet, but there are delayed when i add load on the link (with a scp upload). What is strange is that the delay of thoses ping is not constant: Does someone have an idea about this issue? Thx for any help romary 64 bytes from 10.10.0.10: icmp_seq=1 ttl=63 time=10.4 ms 64 bytes from 10.10.0.10: icmp_seq=2 ttl=63 time=52.8 ms 64 bytes from 10.10.0.10: icmp_seq=3 ttl=63 time=40.4 ms 64
