> So I don't understand this. The so called "bufferbloat" problem is solved in the core? But pragmatically speaking it still exists? This wont get me a PhD, but, one has to ask, why? Does the core drop segments? Or does it buffer them?
It does. Not often, but it does when it needs to.
Most buffer bloat behavior is at the edge - WiFi, Mobile telephone, broadband. There are other cases. But think about dumbbell networks - two fast networks connected by something slower. That's where you'll find it.
