Project JXTA An Open PeertoPeer Network Environment Gene

Project JXTA : An Open Peer-to-Peer Network Environment Gene Kan gene. kan@sun. com Project JXTA Sun Microsystems, Inc.

What is JXTA? • An open network programming platform to enable P 2 P services and applications. • Defines a set of protocols for interoperating • Is language- and network-independent • Is 100% open source, available at: http: //www. jxta. org

What is P 2 P? • P 2 P has many examples: • Sharing files or swapping music • Sharing CPU and storage resources • Distributed search and indexing • Instant messaging & pervasive devices talking with one another • Serverless collaborative work (and play) • New Smart Web Services • New forms of content distribution Adapted from an IBM presentation on P 2 P

Sun's interest in peer-topeer • P 2 P is the continuation of our vision -“The Network Is the Computer” • Demonstrate continued thought leadership • Ensure open, level competitive field • Advance Sun’s readiness for P 2 P • desktop software, workstations, compute farms, i. Planet products, servers, storage, network appliances

Evolution of computing

Project JXTA: why now? • • • More people connected, more data generated More nodes on the Internet and wireless Web More bandwidth available More computing power available (disk, memory, CPU) More interesting applications, content, and services Edge devices increasingly providers of resources Network Computing Explosion Devices Everything that touches the network is growing at an exponential rate Data s User s ice v Ser dth ndwi ons cti nsa Tra Ba Use of the Network/ Value of the Network

Problems with today's Internet • • • Information: hard to find, impossible to catalog and index Bandwidth: hot links get hotter, cold ones stay cold Computing resources: heavily loaded nodes get overloaded, idle nodes remain idle

Benefits of peer-to-peer • Theory • Dynamic and adaptive discovery of information • Performance and functionality increase as more peers participate • Better utilisation of bandwidth, processor, storage, and other computing resources • Extend RAID concepts to computing resources • Examples • • Sharing content cache over high speed LAN Data mirroring and striping using shared storage Deep search beyond the web Dynamic collaboration

Project JXTA: an open community • • Sun: initiator, contributor Open source community • • Adopt, innovate, develop, promote Apache licensing gives developers flexibility • (Modified BSD license. ) • Everyone is free to use source code. • Only requirement is to acknowledge Sun. • Not required to publish modifications to source code.

Problems with other peer-topeer systems under development • Proprietary • Others aim to create a system from which they can profit directly. • Lease the intellectual property or lease the network. • Computing silos: non-interoperable, fragmented networks • TCP/IP only: built-in dependency on TCP/IP transport

JXTA technology objectives • • • Interoperate across different peer-topeer systems and communities Platform independence (programming languages, system platforms and networking platforms) Ubiquity: • Every device with a digital heartbeat • J 2 ME MIDP for now
