Thanks for replying :)
I have been playing a bit with the following setup, but unfortunately I amconfused about how to specify the queue length of my multicast class below, to absorb the small bursts seen. It would be great with an example, for example with a megabyte buffer.
# QDISCtc qdisc replace dev eth3 root handle 1: htb default 30
# CLASSES
# root classtc class replace dev eth3 parent 1: classid 1:1 htb rate 5mbit ceil 5mbit burst 50Kb cburst 100Kb# multicast classtc class replace dev eth3 parent 1:1 classid 1:15 htb rate 5mbit ceil 5mbit burst 50Kb cburst 100Kb
# other traffictc class replace dev eth3 parent 1:1 classid 1:30 htb rate 1mbitceil 5mbit
#filters here (not shown)
Thanks,
Oivind

please help me with directions using tc for configuing leaky bucketshaping to this stream? I have a 5mbit/s ceiling.My system is running gentoo linux 2.6.14, and I have compiled in all
QoS modules.I suppose it depends what you want to do with the burst ie. propogate it,smooth it without loss or drop packets to maintaina rate. I would like to smooth the bursts out at the ceiling bandwidth without
any packet drops (unless an unacceptable lengthy burst of course).Sorry for not replying earlier, I lost this one.What you want should be OK with htb/tbf/hfsc ratelimiting at 5meg - justchoose a leaf queue/buffer length that can absorb the burst.
