Seems there's a userspace shaper out there called shaperd.
The newest versions seem to be maintained by some polish guys, and of course to make the whole thing very interesting the whole documentation seems to be in polish.

Not that I want to use it (I'm way too proud of my 5 lines tc script now), but I'm just curious about it... anyone knows more?
Rolf,
1. This is what you need --> http://uf.kadan.cz/cbq/
It is called "cbq.init" a sample frontend script with text-based conf file that lets you easily to configure "a shaper" without having to bother with the in-deep details :)
2. There is also htb.init. In my opinion, HTB handles the traffic more correct than CBQ.
3. With no offense to you and to the other members - asking such a thing in this forum is
like fishing into one of the canals of Beirut :)
There is no fish there, but just muddy water :)
There are good Linux networking/sysadm forums on the Net. I was used to hang out on the Redhat mailing-list, pretty useful and widely populated :)

Thanks
I have got now a small shaping script that will make 2 HTB classes.
Ack packets and ICMP and QOS interactive packets will go into class one (high prio) and the rest into class 2.
I can see a clear difference when downloading and uploading at the same time, for example when the secretary is sending a big email and I'm downloading some file. It is due to Ack packets being given higher priority.
When doing simultaneous upload and download, these are the measurment (64/256 connection)
Without shaping:
Up : 7.25 K
Down: about 8-9 K
With shaping:
Up : 6.9 K
Down : at least 17 K
I forgot the exact numbers but the difference is quite impressive.
QoS is very important thing... but downlink direction must be QoS'ed on ISP side (before bottleneck - his shaper), i am preparing solution for all our customers, so they can order custom QoS on their needs.
