+200 universities (yellow dots)

Additional Membership

Over 60 Internet2 Corporate Members

Over 40 Affiliate Members

Government Research Agencies

Internet2/U.S. Government: • separate but interdependent• Internet2 is led by higher education• Focused on research and education needs

Internet2 International Partner Program

Internet2/U.S. GovernmentSeparate but Interdependent

U.S. Government• NSF leadership role in NSFnet• NSF’s vBNS served as first Internet2 backbone• NSF and other agencies fund next generation internet research,

infrastructure, applications

Internet2• Led by higher education• Focused on research and education needs

Interdependent:• Government agency funding to research, connections, applications

development• Science and engineering funded projects increasingly dependent

on persistent, high-performance infrastructure provided by Internet2 community (at campus, regional and national levels)

Internet2 Focus Areas

Advanced Applications

Middleware

Engineering• End to End Performance

Advanced Network Infrastructure

Partnerships

Internet2 Backbone Network:Abilene

2.4Gbps upgrading to 10Gbps

Driving deployment of advanced services - native IPv6, native multicast, measurement infrastructure, QoS

215 participating institutions

• Lead connectors at backbone speed

Connect millions of students, faculty, and staff

Extending Availability:State Educational Networks

Internet2 members sponsor Abilene participation

Currently 18 State-based education networks

Enables collaboration using advanced networking for K20, museums, libraries, etc

Additional regional and state investment

Abilene International Peering (August 2002)

IPv6

Focus 1: Running native, high-performance IPv6 on Abilene backbone routers

• IPv4-IPv6 dual stack running on Cisco GSR 12008 routers • Will run dual stack on Juniper T640 from installation

(starting August 2002)• Motivations

– Resolving IPv4 address exhaustion issues– Preserving original End-to-End Architecture model– International collaboration– Router and host OS capabilities

Focus 2: hands-on training at campus level, 6-10 workshops this year

End to End Performance Initiative

To enable the researchers, faculty, students and staff who use high performance networks to obtain optimal performance from the current infrastructure on a consistent basis.

Raw Connectivity

Applications Performance

E2E Performance Initiative Work

Understand applications and their performance requirements

• Technical Advisory Group

Provide best practices/experience for network operators

• Collecting Performance Stories

Help the application user troubleshoot problems• Measurement Architecture Document • H.323 Beacon • Reflector Development

Bring all of this together for the end user• Performance Analysis Station and GUI for End-User Solution

Internet2 Middleware Initiative

Focus on core middleware as infrastructure

Issues:• Interoperability• Implementation on campuses• Integrate with and support applications (upper) middleware, e.g. Grid

Shibboleth

Facilitates inter-institutional sharing of web resources subject to access controls

Examples:• Students enrolled in a course across multiple universities

accessing class materials and Learning Mgmt Systems• Research workgroups sharing controlled resources (the original

web)

Users register only at their “home” or “origin” institution

The release of the beta code is due in August and a production code release scheduled for October

Result: uses of Internet2 networking environment

Numerous applications in use/being developed

• Remote instrument access• High-quality video-conferencing

Internet2 Tomorrow

Nationwide backbone capable of gbps+ flows• Explore optical technologies

– New types of transport technologies– Wavelength switching– Potential for another 10x leap in bandwidth

Cooperatively managed, high-performance global network infrastructure

End to End Performance analysis tools

Middleware components built into popular applications

• Shibboleth for video-conferencing

Global Terabit Research Network (GTRN)http://www.gtrn.net/Cooperatively, cohesively manage

intercontinental infrastructure • Focus on end to end performance on global basis for

global science

Initial partners: • Europe NREN Consortium/DANTE• Internet2

Need global engagement by continent• CANARIE engaged• Asian partnership• Assisted by public & private infrastructure investment

GTRN Current Infrastructure

DANTE-provided router in NYC in GTRN AS

DANTE-provided 2.5gbps links across Atlantic to GEANT

Abilene providing tunnel between New York, (Chicago), Seattle

NSF-funded StarLight will provide GNAP Pacific Wave hosting GNAP in Seattle

Supporting New uses, applications

Internet2 in the Dot.com/Telecom Collapse Environment

Advanced infrastructure for research & education more difficult to acquire.

Corporate R&D spending greatly reduced

• Labs & startups

Internet2 has a more clearly defined but broader mission

Requires partnership across the planet
