And so, it is not reasonable to review the purpose of congestion control?

Sometimes, I don't have the impression that I miss the forest for the 
trees, but we argue for different forests here.

Forest 1: Stability. (Nearly forgotten, hardly mentioned in many PhD 
theses I read throughout the last decade, the only .)

BTW: This forest is quite interesting, because from the system theory 
perspective, the often so called "buffer bloat problem" may well be a 
stability problem.
(BTW2: This forest is mentioned in the congavoid paper in a footnote - I 
strongly suspect this one of the most ignored footnotes in computer 

Forest 2: A reasonable trade off between work conservation on the one 
hand and acceptable delay on the other. IIRC this is Raj Jain's forest.

Forest 3: Sharing and allocation of resources. IIRC the most 
comprehensive, if to my understanding not that widely accepted, work in 
this direction is Keshav's PhD thesis.
