Re: Big downloads ruin voice quality despite QOS

said by mdseuss:

To be a pedantic naysayer, you CANNOT do true QoS without control of BOTH ENDS of the link that has the bottleneck (the consumer spigot).

Yes you can achieve nearly wonderful things with traffic shaping and "consumer grade Qos" settings, but you are really just herding reasonably well behaved applications to avoid them stepping on each other.

If your ISP has you throttled to 5mbit, the bottleneck is on their gear, not at your router.

Your router can decide which traffic has priority to use the available 5 Mbits in your example. If you have the right router.

In almost all cases your ISP network is not saturated or overloaded, only the last mile link to your house is limited in speed. A good router manages this in both directions, given proper configuration.

Doesn't matter what kind of router you have. If don't control BOTH ENDS (and hence the middle) of the "thing that needs QoS", then you aren't doing REAL QoS.

This isn't "wild accusations". Just simple networking and perhaps queue theory.

Now you're repeating yourself. Done here . . .
