  People who talk
       Advanced VoIP
What’s my vision of “advanced VoIP”?
Honestly, I have no idea!
OK, so how can we nurture advanced
Before answering this question, it’s
useful to consider the history of earlier
communications technologies…
              Early History of the Telephone

For the first 30 years of the telephone, promoters struggled to identify
the killer application that would promote its wide adoption by home
owners and businesses. At first the telephone was promoted as a
replacement for the telegraph, allowing businesses to send messages
more easily and without an operator. Telephone promoters in the
early years touted the telephone as a new service to broadcast news,
concerts, church services, weather reports, etc. Industry journals
publicized inventive uses of the telephone such as sales by telephone,
consulting with doctors, ordering groceries over the telephone,
listening to school lectures and even long distance Christian Science
healing! The concept that someone would buy the telephone to chat
was simply inconceivable at that time.
                                          Bill St Arnaud’s summary of
                                     C. Fischer’s book America Calling
                Other Earlier Communications

   •   The popularity of email was not foreseen by the ARPANET's
       planners. Roberts had not included electronic mail in the original
       blueprint for the network. In fact, in 1967 he had called the ability to
       send messages between users “not an important motivation for a
       network of scientific computers” . . . . Why then was the popularity
       of email such a surprise? One answer is that it represented a radical
       shift in the ARPANET's identity and purpose. The rationale for
       building the network had focused on providing access to computers
       rather than to people.
                          J. Abbate, Inventing the Internet

Peer-to-peer file sharing
   • Again, not foreseen
   • Essential ingredients: Internet2 connectivity + directory services
     (Napster, etc.)
           And the Moral Is…

Business and technology leaders…
  • …have a poor track record of predicting how new
    communications technologies will be used
  • …tend to underestimate social or seemingly “frivolous”
    uses of new technologies and overestimate the
    importance of content

Users are highly motivated to communicate
with each other, if only they can connect
               Internet2’s Secret Sauce

  • ~4 million students (tech-savvy and talk a lot)
  • And, by the way, they graduate (tech-transfer à la email)

  •   Great networking connectivity
        – High-bandwidth, low-loss, low-jitter
        – End-to-end transparency (few NATs)
        – IPv6 and multicast too!
  •   Emerging middleware infrastructure / connectivity

Institutional Commitments
  • Internet2 members have committed to advance IP communications
    and promote collaborative apps
  • Many are looking for ways to reverse eroding voice revenues
Fearless Leader
  •   Dennis Baron <>

  • Grow number of SIP connected users
  • Increase value proposition for end-user SIP adoption
  • Promote convergence of voice and email identity
  • Low entry-cost means for campuses to...
        – Provide a useful service
        – Start getting their feet wet with SIP

  • Publishing “cookbook” with several alternative “recipes”
  • Obtaining corporate sponsorship and promotional pricing Growth

Survivability through diversity
   PSTN and Internet each have strengths and weaknesses
   Internet allows for gradual degradation of voice quality,
   rather than call blocking, which is what you want in an
   Combining VoIP and PSTN results in better voice
   survivability than either architecture alone
      Presence and Integrated
  “Notification of events that facilitate
  communication” (Henning Schulzrinne)
     “On-line”, “Away”, “Idle”, “On phone”, “Out to lunch”, ...
  Back to the future
     Remember: finger, write, who?
     Presence restores the sense of community that existed
     on timesharing systems
  Forward to the future
     New standards for interoperability and scalability
     User-controlled policies
     Richer state semantics and automatic triggers
