What We’ll Cover...
Basic elements First- generation systems (briefly) Second-generation systems (Tomoye) Third-generation systems Outlook
AIT
Peer-to-Peer (Simplified)
AIT
Basic Elements - 1
File transfer—This is moving a binary from Machine A to Machine B without need for a human to do much more than click a button
File sharing—This is the set of security bits that tell another system that it is okay to read, change, copy, or perform some other function on another machine offering a directory to the public or to users with specific permission
AIT
Basics - 2
Telnet services—The basic plumbing of any Internet Protocol function resides in some form in peer-to-peer architectures
Instant messaging—America Online type communications with provisions for voice and video
Software transfer and distribution—Mechanisms to distribute to multiple clients
AIT
First-Generation Collaboration
Mailing lists Usenet groups Bulletin boards Proprietary systems
– AOL Instant Messenger– Microsoft Messenger
AIT
Proven Enhancements
SMS -- Wireless simple message system Internet telephony with instant text
messaging Video conferencing via Internet
AIT
Instant Messaging
Send and receive messages in real time without the delays associated with email transmission.
Supports contact lists of groups of associates
Automatically detect if “buddies” are online
Send messages or enter a virtual conference.
AIT
Internet Telephony
Initiate a call and transmit it to any telephone in the world.
Mouse button controls when you want to speak or listen to the other party.
Link learners and trainers Cost around 10 cents a minute to dial any
place within or outside the United States. Minimal security www.net2phone.com
AIT
Desktop Video Conferencing
Combines imaging and communication capabilities
Set up:– Duplex sound card– Web camera– Bandwidth
Microsoft Netmeeting or an ASP such as WebEx (www.webex.com)
AIT
Second Generation Systems
Mostly baloney Virtual auditoriums where peers can co-
edit or analyze files in real time. Tomoye (www.tomoye.com)
– Community Web portals– Example: One Fish
AIT
An Example of Research systems
www.onefish.org
AIT
Community Workflow
Bottleneck--Major flaw in “gatekeeper” systems
AIT
Other Features
Chat Calendaring & Scheduling Auctions Online RFP/RFQ Distance learning/accreditation Virtual tradeshows
AIT
Third Generation Systems
Peer-to-peer architectures Minimize bottlenecks Provide “core” features:
– Messaging– Shared file access– History / archive– Support for rich media -- if bandwidth
available
AIT
Peer-to-Peer
Two or more users form a community No network administration Share
– Files– Messaging
AIT
Three Types of P2P
Many-to-many -- the Napster model Few-to-many -- SETI model Few-to-few -- the work flow model
AIT
Who Uses Napster?
AIT
Searching Result of Napster
AIT
How It Works
AIT
BearShare
AIT
Few-to-Many
Coordinated computers chop up work Available computers signal they are online Coordinators transfer data Available computers complete work Work sent back to coordinators
AIT
A Cheap Supercomputer
AIT
SETI
SETI@Home system -- Analyze data from radio telemetry monitoring stations
More information at www.seti.org Berkeley provides programming and
management ( http://setiathome. ssl.berkeley.edu/
Spare processing and storage on many peer machines; used when the peer machines are idle

Commercial Momentum
Applied Meta Computing has government customers such as NASA and the Defense Department as well as clients from the Fortune 500. The company has received what it calls “a significant investment” from Polaris Venture Partners, an early stage venture firm with over $1.2 billion under management. http://www. appliedmeta.com
AIT
Commercial Momentum - 2
Data Synapse offers its Web Proc product to financial institutions, banks, broker deals, and others with high-demand computational requirements. http://www.datasynapse
AIT
Commercial Momentum - 3
Parabon Computation offers the Frontier distributed computing product and for-fee services aimed at biotechnology, financial and pharmacology research. A person wanting to participate in a Parabon project can download the Pioneer applet. Parabon pays individuals to participate in its projects. http://www.parabon.com/
AIT
Commercial Momentum - 4
United Devices, founded by SETI@home founder David Anderson. The company’s major customer is Exodus Communications. United Devices provides software tools to allow those required distributed network to build, enable, deploy, and support an Internet-distributed computing project. http://www.uniteddevices.com/home.htm

Collaboration
Built into many portal and KM tools...test before you buy
Different twists can be confusing ... have a plan
Monitor the Microsoft technology ... cheaper solutions coming in next 6 to 12 months
Use the stable first- and second-generation tools to build experience
