Does anyone know anything about the level of support for QoS in routers and BRAS devices on the internet itself?
I read some encouraging things in various docs from BT. I'm not at all sure about my ISP though, and my router doesn't speak QoS, afaik.
Second question: Check my brain, which has completely failed temporarily: Where does QoS really need to live in terms of which routers in the path? Where the bottlenecks are? Or will it help just deploying it upstream of a bottleneck, or what?
