1. 1-1 Introduction

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. 1-1 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.

4. 1-1 P2P Makes Sense 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 are increasingly providers of resources Network Computing Explosion Use of the Network/ Value of the Network Bandwidth Transactions Services Users Data Devices Everything that touches the network is growing at an exponential rate

5. 1-1 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

6. 1-1 What is JXTA? An open set of XML-based protocols for creating peer-to-peer style network computing applications and services – Protocol based --> language, OS, network, and service agnostic technology – A virtual network overlay – Defines mechanisms, not policies – Open Source project: www.jxta.org

7. 1-1 JXTA Enables Classic P2P Applications Communications, collaboration, gaming Content delivery and sharing networks Transactional web services Resource sharing
