I guess something similar could be implemented on upstream by limiting the rate of the 'grants' for 'ill-behaved' streams.

Thinking about the downstream, this definitely seems to explains why the TBB graph can look quite good even though download speeds have dropped significantly due to congestion; infrequent ICMPs being scheduled in advance of download packets for other CPEs.

I would have thought this constitutes a form of traffic management / priority scheme?
