40
Voice Killer App Now Forever
  • Primary means of real-time human communication
  • Not high b/w, but very high value per bit
  • Has been and will be a killer app for a long
    time
  • Q Voice / data convergence has been inevitable
    for 20 years. Why, outside of the core, has it
    occurred at such a glacial speed?
  • A Perhaps, the value proposition to users has
    not been made? Perhaps, the vision has been
    myopically focused on matching POTS
    feature-for-feature?

41
Better Voice Through IP
  • VoIP can be so much more than POTS!
  • Potential dimensions of improvement
  • Fidelity
  • Privacy
  • Addressing
  • Mobility
  • Internet2 needs to create a space to explore
    advanced VoIP

42
Advanced VoIP
  • Whats my vision of advanced VoIP?
  • Honestly, I have no idea!
  • OK, so how can we nurture advanced VOIP?
  • Before answering this question, its useful to
    consider the history of earlier communications
    technologies

43
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.

44
Other Earlier Communications Technologies
  • Email
  • 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.)

45
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

46
Connectivity is Key!
47
Internet2s Secret Sauce
  • Demographics
  • 4 million students (tech-savvy and talk a lot)
  • And, by the way, they graduate (tech-transfer à
    la email)
  • Connectivity
  • 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

48
SIP.edu
  • Fearless Leader
  • Dennis Baron ltdbaron_at_mit.edugt
  • Goals
  • 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
  • Means
  • Publishing cookbook with several alternative
    recipes
  • Obtaining corporate sponsorship and promotional
    pricing

49
Remember, Its People Were Connecting
  • Addressing
  • Users should not be burdened with device
    addresses, when its people they really care
    about
  • Addresses should be mnemonic and empower
    enterprises to manage the identities of their
    users
  • sipben_at_internet2.edu
  • Its time to put E.164 phonenumbers behind us!
  • A.G. Bell did not say

Voice Disaster Recovery
  • Fearless leader
  • Chris Peabody ltpeabodyc_at_georgetown.edugt
  • Higher-ed is critical national infrastructure
  • Internet2 schools cannot go dark during disasters
  • Too many important brains, hospitals
  • 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 emergency
  • Combining VoIP and PSTN results in better voice
    survivability than either architecture alone
