Our work on dealing with congestion estimation uncertainties through 
probabilistic response at end hosts (PERT) might interest you:

I'd appreciate opinions about

Extensions will be discussed at ICCRG next week.

Why do I care?  It would seem that instead of improving on the endpoints' 
guesswork about the behavior of all segments of the network between them, we 
should just install intermediaries that _know_ about the behavior of 
particular segments -- Phoebus for example, right?
However, it's not easy to get the right intermediaries at the right points 
all working together, especially when you're interconnecting different 
networks, e.g. going from Urbana to Lyon, so the e2e argument continues to be 
powerful.

So what do you think about this paper particularly, and any other attempts to 
improve on performance without any help from intermediaries?

Thanks ... Scott
