I'd appreciate opinions about

http://conferences.sigcomm.org/hotnets/2011/papers/hotnetsX-final100.pdf

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
