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.
1-2 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. 1-3
P2P Makes Sense Now
• More people connected, more data generated Network Computing Explosion • More nodes on the Internet Everything that touches Devices and wireless Web the network is growing • More bandwidth available at an exponential rate Data • More computing power Users available (disk, memory, CPU) Services Transactions Bandwidth • More interesting applications, Use of the Network/ content, and services Value of the Network • Edge devices are increasingly providers of resources
1-4 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

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
1-6 JXTA Enables Classic P2P Applications
• Communications, collaboration, gaming • Content delivery and sharing networks • Transactional web services • Resource sharing

TINI lets you Internet-enable any device. JXTA gives you peer-to-peer capabilities. Combine them both and you've got peer-to-peer appliances.
• Your refrigerator can work with your freezer and other appliances to track inventory • Assembly floor robots can cooperate in construction • Physically distant climate microsensors can generate knowledge from raw data • TINI MP3 players can exchange music data and metadata • And more!
