Efficient queue management with three classes

RouterOS General
1

the sebastia user uses an effective queue system, which consists of 3 simple classes ; here’s what he writes:

I got 3 classes: “20”, “30” & “FT” for bulk / rest. The last one is where FastTrack is defaulting to.
For classification I’m not using the QOS/DSCP classes (64 possible classifications), but assigning specific traffic to one of the first 2 classes. That is achieved by doing mangling on the connections & packets passing through router.
The remaining traffic defaults (no mark) to bulk class, which is FastTrack-ed.

Do we want to talk about it?
It seems to me a really good way to use the queue!

Hey

Do you have any specific questions?

Cheers

I take this post to not disperse some information, I wanted to implement HTB, but I can not write the correct rules of mangle, especially to prioritize voip and ICMP traffic, bypass fasttrack.
Someone can help me.
I tried some rules but nothing works.
