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
9
Applications:
Advanced Networking in Action
10
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

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

Challenges to the Future
of the Internet
Limited scaling of end-to-end
communications
Security: authentication & privacy
Abuse of network resources by
applications
Reduced investment in the Internet
commons

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

• Call authentication
 Critical to a broad range of
• Spam prevention
initiatives and applications
 Being adopted and
implemented
• Industry
• International partners
23
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
24
NG911 Project
NTIA-funded project
• Will deploy proof-of-concept deployments of IP-PSAPs
• Texas A&M and Columbia University with…
– Internet2
– NENA
– Cisco
– Nortel
– State of Texas
– State of Virginia
Not only solve VoIP 911, but do better!
• Higher resilience
• Faster call setup
• Testability
• Multimedia support
• Open standards and COTS
• Cheaper
Demonstration planned for first week of May
in Washington, DC

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
