JXTA platform is an open network computing platform designed for peer-to-peer (P2P) computing. The JXTA platform standardizes the manner in which peers:
- Discover other peers
- Advertise Peer resources (Peer, PeerGroup, Service and Pipe Advertisements)
- Communicate with each other (Pipes)
- Cooperate with each other to form secure peer groups (group membership)
The Platform project is a Java Standard Edition reference implementation of the JXTA protocols.
The Platform project was the original JXTA implementation and was built in Java, because Java enabled us to rapidly prototype and test new ideas and develop a more robust implementation.
Java is available on most client platforms (Unix, Windows, MacOS X, etc.) and allows us to reach the maximum number of potential users.

- The data stream is signed, you can be sure that it arrives unchanged
- Very efficient communication (low overhead)
- The network structure can be viewed with a monitor
