Résumé

JXTA is a set of technologies under development at www.jxta.org, an open source project managed by Sun Microsystems, and headed up by the inventor of JXTA, Bill Joy. Bill is one of the people who invented UNIX, co-founded Sun, and then helped invent Java. His last technological contribution was to develop Jini, a distributed computing architecture that has been taken on by, among others, the US defence department.

JXTA is a different approach to a similar problem - that of building computer systems that can dynamically discover and co-operate with other similar systems, anywhere on the Internet. This kind of interaction characterizes some of the most interesting applications that have appeared for the Internet in the last year: Napster, Gnutella, Morpheus, and their relatives, all described as 'peer-to-peer' applications. In these systems, a user installs a client program, which discovers other installed clients on other machines, and communicates with them - allowing the sharing of files, such as MP3s, between computers. This peer-to-peer architecture is a completely new paradigm in software design, representing a totally different approach to the standard client-server frameworks used in almost all the distributed systems that currently exist.

JXTA aims to provide a set of technologies that allow programmers to develop clients and services that can interact in this way, without having to implement all of the elements that make up such a system themselves. Aspects such as discovery of peers, advertising presence, penetrating firewalls, and transferring data, which are common to all peer-to-peer applications, are handled by a set of standardlibraries that are available to a JXTA application.

JXTA is a basic tool, on top of which it is possible to build anything; in that sense, it's a lot like a fundamental computing platform, like an operating system. An operating system such as UNIX provides very little functionality in and of itself - it mediates between programs and hardware resources (disk, keyboard, monitor, memory). The power of a UNIX system is provided not by the operating system itself, but by the programs, which run on it (web servers, word processors, games, etc.). JXTA is the same - it provides little functionality, but many possibilities, for the development of applications that have yet to be invented.
