My somewhat biased capsule summary is:
Algorithms:
Reno: Linux never really implemented pure Reno anyway, see
http://www.cs.helsinki.fi/research/iwtcp/papers/linuxtcp.pdf
This makes anybody doing pure ns2 based comparisons suspect.
The problem is Reno rolls off

The only other option would be HS-TC

Can you propose a better alternative other than Reno?
You've cited only "unknown unknowns" and that's not something tangible
we can work with.

This isn't really a reply to anyone in particular, but I wanted to touch
on a few points.
Reno. As Windows decided to go with "Compound TCP", why we want to
back to 80's algorithm?
It's worth noting that Microsoft is not using Compound TCP by default,
except in Beta versions so they can get

It is not the algorithm "untested" -- it is the implem

OK. I get the point. I am more conservative by nature and more of an academic.

Since no one really agrees on the relative merits and problems of the
different algorithms
The TCP Vegas implementation is buggy, and BIC is too agressive
so they should not be in the default list. Westwood is okay, but
not well tested.
