How do you implement this for lots of clients and servers that have out of=
the box implementations? The FastSoft box is a TCP man-in-the-middle box =
that essentially implements the FAST TCP algorithm without either end havi=
ng to worry about it.
I have also used home-fudged TCP proxies with some success.
Some 3G/wireless/VSAT vendors implement their own TCP modification stacks =
but they usually only fiddle with window sizes and such.
