Advancing Real Time Communication on Campus Douglas E. Van Houweling President and CEO, Internet2 10 March 2004
Internet2 Mission and Goals Internet2 Mission • Develop and deploy advanced network applications and technologies, accelerating the creation of tomorrow’s Internet. Internet2 Goals • Enable new generation of applications • Re-create leading edge R&E network capability • Transfer technology and experience to the global production Internet
Internet2 Partnerships • Internet2 universities are recreating the partnerships that fostered the Internet in its infancy • Industry • Government • International • Additional Participation • Over 60 Internet2 Corporate Members • Over 40 Affiliate Members • New Association Member Category • Over 30 International Partners
Internet2’s Secret Sauce • Demographics • ~3.8 million students (tech-savvy, talk a lot, adapt easily) • And, by the way, they graduate (tech-transfer à la email) • Institutional Commitments • Internet2 members have committed to advance IP communications and promote collaborative apps • Commitment to advance communication way beyond POTS • Connectivity • Great networking connectivity and campus middleware • High-bandwidth, low-loss, low-jitter • End-to-end transparency (few NATs) • Emerging middleware infrastructure for authentication & authorization • IPv6 and multicast too! • Strong commitment to open standards
Advanced Collaboration Apps Access Grid VRVS • Multimedia large-format displays • Presentation and interactive environments • Interfaces to GRID middleware and data visualization environments • Supports group-to-group interactions • Use of native multicast
Mass-Use Communications • Many ways to improve collaboration and communications… • Multi-media integration • Rich presence • Integration with campus IT • Use of IPv6 and multicast • Fidelity • Privacy • Addressing • Survivability • Emergency services * Drawings by Louis Teitelbaum (age 6)
Rich Presence Trials1/2 • Participatory trials of SIP/SIMPLE services • Location, calendaring, and “Internet weather” presence • Rich presence enabled through integration with directories, calendaring, and performance monitoring systems • Great dialogue started on the potential of the technology and on the challenge of presence privacy management • Server • Open source • Iptel.org’s SER extended with presence agent module • Integrated Wi-Fi-based location tracking system (HP Labs) • Documenting and packaging for general release Alice (alice@foo.edu)Salon1 IM (poor) Bob (bob@bar.edu) Salon2 (“Deploying IPv6”, over in 12 min) IM
Rich Presence Trials2/2 • Clients • SIPC (Columbia IRT) • Session (Wave Three Software) • eyeBeam (Xten) • Key corporate partnerships • Ford Motor Company • Hewlett Packard • Wave Three Software
Internet2 Commons • H.323 Videoconferencing Service • Production, subscription-based service • Feature-rich; GDS; Firewall traversal • Conference streaming and archiving • HELP! 24/7 NOC (OARnet/OSU) • Quarterly Trainings (100+ site coordinators) • Hosted try-then-buy environment for real time collaboration tools • Wave Three Software SIP collab suite • InSORS • …others coming soon
Challenges to the Futureof the Internet • Limited scaling of end-to-end communications • Security: authentication & privacy • Abuse of network resources by applications • Reduced investment in the Internet commons

Security • Network security approaches must: • Minimally compromise network performance and application functionality • Sustain, in so far as possible, the end-to-end nature of the Internet architecture • Protect of critical infrastructure and other resources (e.g. human attention) • Enable new capabilities (IP disaster recovery, NG 911) • Texas A&M ITEC focus on VoIP security
NG911 Project • NTIA-funded project • Will deploy proof-of-concept deployments of IP-PSAPs • Texas A&M and Columbia University with… • Internet2 • NENA • Not only solve VoIP 911, but do better! • Higher resilience • Faster call setup • Testability • Demonstration planned for first week of May in Washington, DC • Cisco • Nortel • State of Texas • State of Virginia • Multimedia support • Open standards and COTS • Cheaper

Conclusions • Need open campus / enterprise middleware to scale and secure advanced communication • Must work together to build an IP communications commons that is both secure and flexible
