Re: [XP] Quality of service with VPN?
Thank you for responding.
As you say, i dont really know how QoS works  However, i do have some idea of what i would like to happen 
As to analyzing before the congestion point (at the PC), i was assuming that this would be done by analyzing the TCP packets. By looking at these packets it should be possible to observe the amount of congestion occurring and consequently throttle the low priority traffic. Of course UDP traffic does not give this kind of information so it would probably be a worthless mechanism for applications like Skype etc. However, in my case the traffic is all TCP.
Anyway, I will try to look into bandwidth arbitration/shaping. |

| Yes, of course QOS will force an orderly exit of the packets past that bottleneck that is between the motherboard bus and the NIC, but as I said before, it does not flag the packet with "immunity" to magically grant a higher priority on all the other bottlenecks downstream.
Most arbitration schemes look at source and destination to allocate a fairness to all traffic and the VPN will all be tarred by the same brush.
