Hi
I'm actually using a wondershaper derived script.
The problem I have is that when I ping (ping is in high priority queue)
the ping time is not as low as I expected with p2p running:
760 packets transmitted, 760 received, 0% packet loss, time 759695ms
rtt min/avg/max/mdev = 39.667/62.863/598.539/33.287 ms, pipe 2
With voip, it is much better with the qos but it is still a little choppy.
My line is an adsl 512/128 kbit/s. Assuming the biggest low prio packet
is about 1.5kbyte, this makes a max latency of 93ms higher than min
latency: 133ms in my case. (that's what I notice on the ping times)
I don't understand why is voip still choppy.
In my config, can I assume that packets in 1:10 have the highest
priority even with htb? (if the 1:10 rate is not reached).
Do I need to setup a prio qdisc instead of htb for voip?
If I lower the mtu of the p2p software to 750byte for example, will I
get a max latency of 87ms?
Can I do voip and P2P together with htb with such a line?
Thanks for your help.
