Hi all, 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 Satelite Network. There was a test between Sony in Japan and I 'BELIEVE' JPL in Pasadena of hight def video transmissions over an OC-3 circuit. I heard something about a quasi commercial deployment of another ACTS project. Anybody heard anything about this? If enough birds like ACTS were sent up, this could be a boon for ISP's maybe. Of course I live in this ideal world where everybody is reasonable, intelligent, and well yea I know things are just quite the opposite. If MCI/AT&T/NTT/GTE put this into motion then were doomed, but if Hughes (read someone who doesn't own an ISP yet) put one up, it might be a bit more promising.

The only ISPs that can really afford to stay in the game in a big way "over the long haul" are now the carriers themselves. The end result??? The marketing and pricing strategies of the ISP and market are being commercialized and in the overseas markets looking more like the pricing strategies of the typical telephone service offering.The cost for overseas cables are not going to be coming down in a big way over the next couple of years. They will more likely go up. At least for our foreseeable future. The next few years. The pent up demand is to great.
Now where is Judge Green (is he retired ?) when you need him?! Feds are sleeping as usual....I usually don't like the Feds sticking their noses into places, but I loath the telcos and their continuing lies and extortion of consumers and businesses. Ack. I can't tell you how many times GTE screwes everything up! Chris "Don't get me started bitching about telcos/carriers"

Do satellites really stand a chance against fibre? Most people think not, and more specifically that their competitiveness shall continue to decline as time progresses. Not exactly the kind of thing one wants to lay out large capital expenditures on... Of course, I'm just a tool of conventional wisdom, as poorly conveyed by the media, when it comes to these issues.

Which type of satellite network was talked about? If we're talking the big, far-away GEO satellites, my guess is that the latency involved would kill such a project. OTOH, LEO satellites could work (see: Teledesic), but involve a massive investment and lots of satellites. - Jakob

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 http://mrpink.lerc.nasa.gov/gsnhome.html

You'll find this on on the Experiments page, number 101.

Well, maybe. ACTS is a GEO satellite, and interactive use is painful. On the other hand, it's enabled people to do interesting things with bulk data 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/ ...arun --------------------------------------------------------------------------- Arun Welch 5000 Britton Rd Lead Engineer, Internet R&D Hilliard, OH 43026 CompuServe Network Services awelch@compuserve.net
