8 Sponsored Education Group Participants

9 Internet2s Secret Sauce Demographics ~3.8 million students (tech-savvy, talk a lot, adapt easily) And, by the way, they graduate (tech-transfer à la ) 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 displays Presentation and interactive environments Interfaces to GRID middleware and data visualization environments Supports group-to-group interactions Use of native multicast Access GridVRVS

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 * Drawings by Louis Teitelbaum (age 6)

13 Rich Presence Trials 1/2 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.orgs SER extended with presence agent module Integrated Wi-Fi-based location tracking system (HP Labs) Documenting and packaging for general release Alice Salon1 IM (poor) Bob Salon2 (Deploying IPv6, over in 12 min) IM

16 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

23 Shibboleth 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

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

27 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
