Connectivity + Edge Innovation = New Apps

Connected users will innovate
  • To connect to each other, users need superior network
    connectivity, application connectivity, and ultimately,
    user-to-user connectivity
           Address                     Application Connectivity                               Address




                                                                                Application
                      Application




                                           (call and presence routing)




                                                                                                         User
    User




           Presence                      Network Connectivity                                 Presence
                                    (high-performance, end-to-end IP transit)

Connected teenagers will really innovate!
  • Internet2 interesting not just for its superior connectivity
  • User demographics matter too (~4 million students)
  • Tech-savvy, talk a lot, and they graduate!
                                                                                                                www.internet2.edu
Paths in the Snow
Connected users will drive disruptive change
  • But pure peer-to-peer solutions only go so far
Smart institutions and companies will…
  • Provide tools (applications) to exploit connectivity
  • Watch carefully for opportunities to add value through new services
Campuses manage critical physical and information
infrastructure that cannot be routed around
  •   Directories
  •   Network infrastructure
  •   Middleware infrastructure
  •   Physical infrastructure
  •   Presence services
We are engaging campus telecom leaders to plan
for new services and infrastructure while watching
the paths in the snow

Better Voice Through IP: Addressing
Addressing
  • Users should not be burdened with device addresses,
    when it’s people they really care about
  • Addresses should be mnemonic and empower
    enterprises to manage the identities of their users
     –sip:bob@bigu.edu
  • It’s time to put E.164 phone
    numbers behind us!
  • A.G. Bell did not say:


   “+1-617-637-8562, come here.
   I need you!”
