At my home I have an modest ADSL line with a standard 128kbits upload. The upload is shared between several computers, an bittorrent process and asterisk (VoIP) server. I have looked around for an simple script to balance the upload according to set of very simple rules:
- VoIP packets go out first, no matter what
- ssh, www, smtp, etc go after
- everything else (including bittorrent) go last
After many fruitless hours of trying I have found a sample script at http://www.knowplace.org/pages/howtos/traffic_shaping_with_linux/examples.php and then heavily modified it.
There are only two lines in the script to change. You should be aware of following assumptions in the script however:
- The machine serves as the gateway for your network
- Internet is established using autodialer on interface ppp0
- asterisk runs on the same machine as the shaper
As a result, the VoIP is hitchless, even in presence of unlimited bittorrent upload.You can
