Project SAXTA: An Eco-Friendly Distribution Network to View Earth Data

    Project SAXTA (the acronym SAXTA is derived from SAtellite JXTA) is a new, open network dedicated to the sharing of high-resolution NASA Earth observation data sets such as Landsat and ASTER data. SAXTA is using a decentralized JXTA P2P network architecture that enables users, Earth science scientists, and educators all over the world to freely access and share Earth data without requiring NASA to host a massive centralized infrastructure to serve content.  SAXTA architecture really paves the way for a new generation of eco-friendly distribution network that will help reduce CO2 emissions. When looking for a content, the SAXTA network can determine the closest path to a copy of the content to reduce the number of hops packets have to go through and to minimize overall packet processing and traffic.  MSN and Google's Earth may want to take a closer look at what NASA and the SAXTA folks are doing.

As a side note,  the same eco-friendly JXTA technology used by SAXTA is also powering Sun's Glassfish appserver clustering product :-)

Why We Need A "P2P Eco-Friendly" Internet?

One thing which attracted me to P2P (and to work on JXTA) was that I always thought the Internet will reach a metldown point due to the way information distribution is currently over centralized. Well:  In 2005 it took the equivalent of 14, 1,000-megawatt power plants to keep online the world's data centers owned by Internet giants like Google (GOOG), Microsoft (MSFT) and Yahoo (YHOO). And that's not counting YouTube! As a simple analogy, do we really need everyone PCs to connect to the Yahoo site to read today Yahoo headline news, or can we realize that a PC, next to the cubicle the person is seating, or somewhere in the building, or the city, already has a copy of the article!

If you truly want to save the planet!  It's not too late. Just check :-)
