In other words, rather t= han share the capacity of the link "fairly" among flows (as TCP would if yo= u eliminated excess buffer-bloat), you want to impose control on an endpoin= t from the middle?

TCP and other protocols generally are responsive= when packets are dropped at a congested point, and they generally end up s= haring the available capacity relatively fairly.  If you want even mor= e fairness, use fq_codel.
