Heather BoylesDirector, International [email protected]
Internet2 Yesterday and Today
Launched October 1996• 34 US universities• Formally incorporated as not-for-profit corporation September 1997
• Abilene backbone network announced April 1998
Today• 208 US universities; 60+ corporate members, 40+ affiliates, 45 international partners
• 2nd Generation Abilene backbone network; Internet2 Commons, Shibboleth, InCommon, NLR, QUILT, Arts & Humanities program, etc.

Internet2: Partnerships
Partnerships are key to Internet2International partners are of strategic importance to Internet2
• Ensure global interoperability –of the next generation of Internet technologies and
applications
• Enable global collaboration –in research and education providing/promoting the
development of an advanced networking environment internationally
International Partner Program
Build effective partnerships in other countries With organizations of similar goals/objectives and similar constituencies
Mechanism: Memoranda of Understanding• Provide/promote interconnectivity between communities• Collaborate on technology development and deployment• Facilitate collaboration between members on applications
Engagement to:• Establish leading, high-performance network infrastructures in
support of science, teaching and learning• Ensure global coordination and end-to-end performance in
support of our communities

NRENs in general
The idea of national research (and education) networks (NRNs or NRENS) continues to be popular
• New NRENs in Latin America, Eastern Europe, Mediterranean, Middle East – Pakistan, New Zealand, Jordan
Many of these NRENs incorporate government research lab as well as university connectivity (and sometimes other education institutions)
Regional (continental-scale) backbone growthContinuum from commercial Internet access, to
reliable-leading-edge (production) to experimental to network research facilitating networks
• But locus of most effort on supporting the high-performance, leading-edge needs of high-end science (UK e-Science, US CyberInfrastructure) and other high-end research, education, clinical needs

International connectivity from/to the US
Internet2 backbone networks generally exist within the borders of US
Links between the US and other countries funded through various sources
• Outside the US: many of our partners procure and operate links from their country to the US
• US-funded: US NSF provides funding through IRNC (was HPIIS) program for some links
– DOE provides some funding for CERN-procured and operated links to US
• Donations: IEEAF has garnered donations from Tyco Telecom of international links
How do Internet2 networks connect with these international links?
International exchange points around borders (including north and south borders of US)
• Peculiar challenge in US of connecting with multiple national-scale networks in US (Abilene, ESnet, NREN/NISN, DREN, NLR-based networks (e.g. HOPI), etc.)
Exchange points• Pacific Wave exchange point (West Coast – Seattle/LA)• (UTEP link to CUDI (El Paso – Ciudad Juarez))• AMPATH exchange point (Miami)• Emerging: Atlantic Wave (East Coast – Miami/New York)• MAN LAN (New York)• Star Light (Chicago)
Some direction connections• e.g. to Abilene core router (GEANT in Washington, DC)
In addition to physical network interconnectivity
Moving toward ‘interconnecting’ and ‘peering’ these infrastructures too
• Performance Measurement and Monitoring Infrastructures– NLANR/MNA measurement infrastructure
• Wide international deployment– Internet2 piPEs environment
• Joint development work of Internet2 and GEANT2• PMP deployments in APAN, Brazil, Europe, US
– Abilene considering adding measurement infrastructure to international Interconnection Agreements
• Authentication and Authorization Infrastructures– Cotswolds meeting – Australia, Finland, Netherlands, Spain, Switzerland, United
Kingdom, United States (also CERN) attending– e.g. InCommon trust federation in US (hosted by Internet2),
SWITCHAAI, UK legacy ATHENS, planned Shibboleth-based federation, etc.

National Federations for Inter-institutional authentication and authorization
National federations of institutions• Agreeing to interconnect their respective
authentication and authorization schemes• To support inter-institutional collaboration
Interconnect these national federations• ‘League of Federations’• To support inter-institutional collaborations
internationally• E.g. virtual organizations of researchers –
international ‘grid’ projects• E.g. authenticated video-conferencing• E.g. access to performance/measurement data for
network engineers across domains
AAI
eVLBI - Very Long Baseline Interferometry
Astronomers collect data about a star from many different earth based antennae and send the data to a specialized computer for analysis on a 24x7 basis.
VLBI is not as concerned with data loss as they are with long term stability.
The end goal is to send data at 1Gb/s from over 20 antennae that are located around the globe.
Interesting:eVLBI sites in US and Europe recently tracked and confirmed landing of Huygens probe to one of Saturns’ moons, Titan

Astronomy- Arecibo
Arecibo is the largest
single-dish radio-telescope in the world
Can gather data at 40 MBytes per second
Advanced network connection allows: • Remote observation• Real-time control• Ability to provide researchers access to over 800
TBytes of data collected by the antenna
HENP
High Energy and Nuclear
Physics
Physicists has traditionally been one of the “power users” of all networks
Generating Terabytes (1x1012) of data per experiment from the CERN lab in Switzerland
They are working on bulk data transfers that are extremely resistant to data loss
VRVS, a video conferencing tool, was developed by the physics community
Distance Education/Learning
Tele-presence environments
•Real-time interactions with very high quality audio and MPEG-2 video
• as needed “meetings” connecting faculty and staff across the ocean
Music instruction
Language/cultural Exchanges
Learning foreign languages through cultural exchanges and problem based experiential learning
