Project SAXTA (the acronym SAXTA is derived from SAtellite JXTAâ„¢) 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 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 building.

As a side note, the same eco-friendly JXTA P2P technology used by SAXTA is also powering Sun's Glassfish appserver clustering product :-)

This week the JXTA community executed an impressive "triple-play", releasing simultaneously, for the first time in the project history, 3 different implementations of the JXTA P2P protocols. The 3 implementations are fully compliant and interoperable enabling the deployment of self-organizing, scalable, and secure P2P applications on devices ranging from sensors, phones, ipods, PDAs, PCs, TVs, STBs, DVRs, servers and supercomputers.

1)JXTA-J2SE 2.3.4 (Arroz Congris)

2)JXTA-J2ME 2.0 (Arrakis),

3)JXTA-C/C++ 2.1.1 for Solaris, Linux, Win, and embedded RTOS (Disney).

Sun also announced that Boeing, the lead systems integrator for the U.S. Army's multi-billion dollar Future Combat Systems (FCS) project, has selected the JXTA technology to provide the P2P discovery service for the U.S. Army FCS global network infrastructure.

These latest announcements highlight the continue growth and maturity of the JXTA technology, making JXTA the leading P2P Platform for deploying ubiquitous commercial applications.

JXTA will have a significant presence at JavaOne to reinforce its commitment to the Java developer community.

JXTA community members will also be on hand to share their experiences and expertise on developing and deploying JXTA applications at the JXTA Community Townhall meeting. Please come meet with us and learn about the unique capabilities of the JXTA network for deploying highly-resilient, self-organizing, and scalable ubiquitous network solutions.

While we keep hearing about the misuse of P2P technology for sharing copyright materials in the press, it is nice to point out that there is more to P2P, and P2P presents unique values and capabilities to build scalable, dynamic and highly reliable network infrastructures. The JXTA open-source community is continuing its growth and successes building the leading open-source P2P platform.

Today, Sun announced that Boeing selected the JXTA technology to provide the peer-to-peer (P2P) discovery service for the System of Systems Common Operating Environment (SOSCOE) for the U.S. Army's multi-billion dollar Future Combat Systems (FCS) initiative. JXTA unique P2P virtual network layer and decentralized discovery service is providing unique values to Boeing for deploying FCS within highly dynamic and distributed network environments.

This is great news for the P2P and JXTA community as this is bringing another legitimate usage of P2P. Really no excuses for not trying JXTA now :-)--
