[e2e] Answer to Dave Reed Re: Fwd: Re: Question the other way round:

[Richard Bennett]

Network congestion isn’t, or doesn’t have to be, one enormous global problem that can only be solved one way. It can be viewed as myriad local problems that can be solved in ways that roll up into a coherent algorithm employed in many places at the same time. A big part of the solutions come from classifying flows according to application requirements and willingness to pay for grades of service. 

I’m comfortably predicting that the best solutions will come from the commercial sector rather than the academic/government research sector, just like they have for privacy and security. Government has too many conflicts of interest to be very helpful here.
