Arnold Information Technology <ul><li>Founded in 1991, small team of specialists </li></ul><ul><li>Provides technology assessment and information engineering services </li></ul><ul><ul><li>Planning </li></ul></ul><ul><ul><li>Analysis </li></ul></ul><ul><li>Recent projects: </li></ul><ul><ul><li>Wireless for the world’s largest software company </li></ul></ul><ul><ul><li>University of Michigan next generation network for Kresge Business School </li></ul></ul><ul><ul><li>Design and planning for U.S. government’s </li></ul></ul><ul><ul><li>Inventory and analysis of Canadian online initiatives </li></ul></ul><ul><ul><li>Technical and financial analysis of 24 Application Service Providers </li></ul></ul><ul><li>Contact : [email_address] </li></ul>ARNOLD Information Technology
  4. 4. What We’ll Cover... <ul><li>Basic elements </li></ul><ul><li>First- generation systems (briefly) </li></ul><ul><li>Second-generation systems (Tomoye) </li></ul><ul><li>Third-generation systems </li></ul><ul><li>Outlook </li></ul>
  5. 5. Peer-to-Peer (Simplified)
  6. 6. Basic Elements - 1 <ul><li>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 </li></ul><ul><li>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 </li></ul>
  7. 7. Basics - 2 <ul><li>Telnet services—The basic plumbing of any Internet Protocol function resides in some form in peer-to-peer architectures </li></ul><ul><li>Instant messaging—America Online type communications with provisions for voice and video </li></ul><ul><li>Software transfer and distribution—Mechanisms to distribute to multiple clients </li></ul>
  8. 8. First-Generation Collaboration <ul><li>Mailing lists </li></ul><ul><li>Usenet groups </li></ul><ul><li>Bulletin boards </li></ul><ul><li>Proprietary systems </li></ul><ul><ul><li>AOL Instant Messenger </li></ul></ul><ul><ul><li>Microsoft Messenger </li></ul></ul>
  9. 9. Proven Enhancements <ul><li>SMS -- Wireless simple message system </li></ul><ul><li>Internet telephony with instant text messaging </li></ul><ul><li>Video conferencing via Internet </li></ul>
  10. 10. Instant Messaging <ul><li>Send and receive messages in real time without the delays associated with email transmission. </li></ul><ul><li>Supports contact lists of groups of associates </li></ul><ul><li>Automatically detect if “buddies” are online </li></ul><ul><li>Send messages or enter a virtual conference. </li></ul>
  11. 11. Internet Telephony <ul><li>Initiate a call and transmit it to any telephone in the world. </li></ul><ul><li>Mouse button controls when you want to speak or listen to the other party. </li></ul><ul><li>Link learners and trainers </li></ul><ul><li>Cost around 10 cents a minute to dial any place within or outside the United States. </li></ul><ul><li>Minimal security </li></ul><ul><li> </li></ul>
  12. 12. Desktop Video Conferencing <ul><li>Combines imaging and communication capabilities </li></ul><ul><li>Set up: </li></ul><ul><ul><li>Duplex sound card </li></ul></ul><ul><ul><li>Web camera </li></ul></ul><ul><ul><li>Bandwidth </li></ul></ul><ul><li>Microsoft Netmeeting or an ASP such as WebEx ( </li></ul>
  13. 13. Second Generation Systems <ul><li>Mostly baloney </li></ul><ul><li>Virtual auditoriums where peers can co-edit or analyze files in real time. </li></ul><ul><li>Tomoye ( </li></ul><ul><ul><li>Community Web portals </li></ul></ul><ul><ul><li>Example: One Fish </li></ul></ul>
