2 The Time Is Right for P2P and Project JXTA Peer-to-Peer (P2P) is not new. However, the time is now right for the broad P2P applications deployment. The Project JXTA technology lets developers build and deploy P2P solutions more quickly.

3 Topics Peer-to-Peer computing Project JXTA technology Project JXTA today Future directions

4 What Is Peer-to-Peer (P2P)? P2P covers a wide range of applications Sharing files, distributed search and indexing Sharing CPU and storage resources Instant messaging & devices communicating together Collaborative work (and games) Web services New forms of content distribution, sharing, and delivery P2P is not New or a specific architecture, technology, business model, or market About eliminating servers or centralized services P2P is about any device easily connecting directly to other devices to enable a more cooperative, or social, style of computing.

5 P2P Makes Sense Now More people connected, more Network Computing Explosion data generated Everything that touches Devices the network is growing More nodes on the Internet at an exponential rate Data and wireless Web Users More bandwidth available Services More computing power Transactions Bandwidth available (disk, memory, CPU) Use of the Network/ Value of the Network More interesting applications, content, and services Edge devices are increasingly providers of resources

6 Characteristics of Ideal P2P Applications Applications best suited for P2P implementation are those where: Centralization is not possible or desired Massive scalability is desired Relationships are transient or ad-hoc Resources are highly distributed Resilience is desired Their value or performance increases as more nodes participate in the network

7 JXTA Enables Classic P2P Applications Communications, collaboration, gaming Content delivery and sharing networks Transactional Web services Resource sharing

8 JXTA Sample Applications Wireless P2P on JavaTM 2 Platform, Micro Edition (J2METM) P2P Messaging Group and 1:1 Chat P2P Entertainment TicTacToe Game P2P Image Sharing

9 JXTA Sample Applications -myjxta2 and PicShare

10 JXTA Sample Application Ifreestyle by Digital Dream

11 JXTA Sample Applications -Momentum 1.0 by InView Software

12 JXTA Sample Applications VistaPortal

13 JXTA Sample Applications - Java IDE by Internet Access Methods

14 Protocols Drive Distributed Computing TCP/IP HTTP JXTA Client-Server Web-based Peer-to-Peer

15 JXTA Virtual Network Project JXTA Virtual Network Peer Peer Peer Peer Peer Peer Peer Virtual Mapping TCP/IP Physical Network Firewall HTTP Peer NAT

16 JXTA Peer Types Micro peers Standard peers Super peers: Rendezvous peer Relay peer Proxy peer

17 JXTA Peer Groups Personal Peer Group Workgroup Peer Group Chat Peer Group Corporate Resources Peer Group

18 JXTA Technology Objectives Interoperability Platform independence Programming languages, system platforms, and networking platforms Ubiquity Across different P2P systems and communities Every device with a digital heartbeat Security and Monitoring For commercial and enterprise deployment

19 Any Platform, Any Network JXTA Chat (J2METM) MyJXTA ( J2SETM on Windows ) JXTA Virtual Network JXTA-C Shell (C on SolarisTM)

20 JXTA Core Building Blocks Peer Groups Peer Pipes Send any content (code, data, etc.) to peers Messages in XML format Secure pipes supported Peer Monitoring Manages identity of peers and peer groups Join, Leave, Create Check peers status remotely, control remote peer behavior Meter peers usage, set usage or bandwidth limits Security Pluggable architecture supports a variety of standard security solutions Control group membership Encrypt data sent over pipes

21 JXTA Software Architecture JXTA Applications Sample Applications Instant Messaging File Sharing Collaborative Apps JXTA Services Auctions Sample Services Search JXTA Core Resource Sharing Indexing Discovery Membership Peer Groups Peer Pipes Peer Monitoring Peer Advertisements Peer IDs Security Any Connected Device

22 JXTA Is Based on Protocols JXTA defines XML message formats, or protocols, for communication between peers Protocols used to discover peers, advertise and discover resources, communicate and route messages, and provide monitoring Can be implemented in any language

23 JXTA Implementation Platforms J2SEä Implementation JXTA-C Full implementation of JXTA protocols Standard and Super Peer functionality APIs and functionality frozen Standard Peer functionality only Runs on Linux, Solaris OE, and Windows JXTA for J2MEä Micro Peer functionality only MIDP-1.0 compliant Iappli compliant

24 jxta.org Based on a Proven Open Source Model All source, projects, docs, examples on-line Apachestyle software license No barriers to getting started No royalties, no fees, no registration Meritocracy The more you've done, the more you can do

25 JXTA Community Momentum (4/2001 7/2003) 1,400,000+ downloads 80+ projects 14,000+ members Active discussion groups Community actively contributing and integrating technology Please join our efforts!

26 Community Projects Python Perl Objective-C Ruby SmallTalk Services (e.g. JXTA-SOAP) And many others

27 JXTA Books Early Adopter: JXTA, Sing Li, 2001 JXTA, Brendon J. Wilson, 2002 JXTA: Java P2P Programming, Daniel Brookshire, et al, 2002 Mastering JXTA Development, Joe Gradecki, August 2002 Java P2P Unleashed, Robert Flenner, et al, 2002 JXTA in a Nutshell, Scott Oaks, et al, 2002

28 Looking Ahead Enhanced Performance, Scalability, and Security New services and opportunities E.g. identity, integration with Web services, content management, digital rights, presence Specification standardization through public organization

29 Problems JXTA Solves Provides a set of building blocks and infrastructure that provide a foundation for P2P applications Provides an open and interoperable set of protocols that do not have special licensing requirements Quick time to market for new products and services

30 What JXTA Does Creating Connected Communities Brings devices, services, and networks together Enables interactions among highly dynamic resources Takes the complexity out of the network and operating environments so developers can quickly build applications Users have better access to content across multiple devices, regardless of location Find it, get it, use it

31 Summary Project JXTA is an open source platform for P2P applications it is free! Project JXTA technology is language, operating system, network, and service agnostic. Project JXTA works on any network device -- from cell phones to super servers Project JXTA has a large and active community at
