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
10
Applications:Advanced Networking in Action
11
Advanced Collaboration Apps
Multimedia large-format displaysPresentation and interactive environments Interfaces to GRID middleware and data visualization
environments Supports group-to-group interactionsUse of native multicast
Access Grid VRVS
12
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
Mass-Use Communications

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

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

Communications is Balkanized by competing 3rd parties, who are unable to provide strong authentication, identity management, or rich
presence for their users

Connective Middleware: SIP.edu
Goals• Grow SIP connectivity
and use• Increase value
proposition for early adopters
• Promote a converged electronic identity
Means• “SIP.edu Cookbook”• Vendor Partners
– Cisco– Avaya– others soon
• Community of implementers

Moderating Middleware:Federated Authentication
Open source attribute-based single sign-on software with an emphasis on user privacy, built on the SAML 1.1 specification
Scalable, decentralized infrastructure
Critical to a broad range of initiatives and applications
Being adopted and implemented
• Industry• International partners
A federation for American higher education, initially focused on “.edu” origins
Expected to serve as a trust anchor for a variety of Internet2 efforts
• Call authentication
• Spam prevention
24
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
25
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
• Multimedia support• Open standards and COTS• Cheaper
– Cisco– Nortel
– State of Texas– State of Virginia

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
