  1. Internet2 VoIP and PIC in a Nutshell Ben Teitelbaum <ben@internet2.edu>

  2. Application Connectivity Address Address (call and presence routing) User Application Application User Network Connectivity Presence Presence (high-performance, end-to-end IP transit) 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!

  3. 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

  4. 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 phonenumbers behind us! • A.G. Bell did not say: “+1-617-637-8562, come here. I need you!”
