Re: [PLUG] regulating network traffic
|
I'm fairly convinced that when it comes to incoming data, Qos does nothing really. I have read this a few times on web sites. That it works only for outgoing data. Again, I am hardly a pro at this kind of stuff, but here is a test I ran.
To omit the many many variables for testing (ie: trying to control port numbers), I set up the router to prioritize the ethernet ports on the router. #1 low, and #2 high. I put two ftp's on a machine on #1 and ran a torrent on the machine #2. The speeds fluctuated quite a bit as they battled for bandwidth, but it seems to me that it was basically divided in half. It's hard to tell of course. But if machine 2 can download alone at 80KB/s, it just drops back to around 40 or 50. Sometimes 60. This is about half.
I reversed the priorities and tried again. The results were mostly the same.
I don't think the Qos stuff set in the router gets to propogate and be honored at my provider.
Well, this is getting complicated fast!
