I have been following this thread with some interest. A few months ago a
friend of mine from Fore Systems told me about the 'ACTS' project. NASA and
Ohio-State and quite a few others were doing research into the Gigabit
ACTS has been used for a bunch of stuff, but you're probably thinking of the
high data rate experiments. The home page for ACTS HDR is
There was a test between Sony in Japan and I 'BELIEVE'
JPL in Pasadena of hight def video transmissions over an OC-3 circuit.
You'll find this on on the Experiments page, number 101.
Anybody heard anything about this? If enough birds like ACTS were
sent up, this could be a boon for ISP's maybe.

transfer, and it was probably the first system that got you OC-12 across
any significant distance. There's an IETF WG working on the issues posed by
IP over satellites, whose home page is http://www.isr.umd.edu/CSHCN/Links/IPoS/
