摘要:Tens of millions of people use peer-to-peer (P2P) applications such as KaZaA, AOL Instant Messenger, and Distributed.net. These applications harness the idle CPU cycles of their host computers to produce enormous databases of information, build powerful processing engines, and enable communication and file-sharing among users around the world. With this invaluable book, Joseph Gradecki provides a practical guide to building peer-to-peer applications using Java. He provides detailed descriptions of the JXTA technologies and demonstrates how to build real-world applications.
