[LBo] Traffic shaping in home LAN

[Niki Kovacs]

Hi,

I have a tricky problem to solve. Here goes.

At home I have five machines connected to a DSL router with rather 
limited bandwidth: 512 kbps download, 128 kbsp upload. That's because we 
live in a rather remote place, in a small village in South France. 
(Hell, we had dialup until January, so I won't complain...)

One of the machines acts, among other things, as a streaming audio 
server for my private web radio. It's an old PIII with a CentOS base 
system on it, a black box with only a wireless antenna, that's 
administered via ssh. BTW, if you feel like tuning in: open 
http://80.247.231.122:8000/radionovak.ogg with XMMS or VLC. In fact, my 
server sends the signal to a relay (our library database server :o) ), 
which somehow multiplies the available bandwidth by a factor of 100.

For the moment, I send one signal of 32 kbps upstream to the relay. 
Problem: if one or more machines here at home do some more 
bandwidth-consuming task, like watching videos on Youtube or downloading 
something else... the stream jitters, as there's not enough bandwidth 
available.

Now what I'm looking for is something that would be the reverse of 
'trickle' (you know that nifty little app?). Something that would give 
the audio stream top priority over anything else. So the other PCs can 
share among them the 128 minus 32 kbps upstream bandwidth.

Any suggestions?
