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

  • 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!


Paths in the snow

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

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

    • It’s time to put E.164 phonenumbers behind us!

    • A.G. Bell did not say:

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