What is JXTA?

• An open network programming platform to enable
  P2P 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 P2P?

• P2P 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

Sun's interest in peer-to-peer

• P2P is the continuation of our vision -- The
  Network Is the Computer
• Demonstrate continued thought leadership
• Ensure open, level competitive field
• Advance Suns readiness for P2P
• desktop software, workstations, compute farms,
  iPlanet products, servers, storage, network
  appliances

Evolution of computing

Project JXTA why now?
Network Computing Explosion

• 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

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

8
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

9
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.

10
Problems with other peer-to-peer 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

11
JXTA technology objectives

• Interoperate across different peer-to-peer
  systems and communities
• Platform independence (programming languages,
  system platforms and networking platforms)
• Ubiquity
• Every device with a digital heartbeat
• J2ME MIDP for now

• 25 projects
• 5000 members
• Active discussion groups (4000 msgs)
