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.

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 P2P is about any device easily connecting “directly” to other devices to enable a “directly” to other devices to enable a more cooperative, or social, style of more cooperative, or social, style of computing.computing.

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

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

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

JXTA Sample Project — tini.jxta.orgTINI 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!

JXTA Technology Objectives

• Interoperability– Across different P2P systems and

communities

• Platform independence– Programming languages, system

platforms, and networking platforms

• Ubiquity– Every device with a digital

heartbeat

• Security and Monitoring– For commercial and enterprise

deployment
