History
ARPAnet origins
NSFnet
• Research and development cycle
• Privatization in 1995
Higher ed planning in 1995/1996
• Are our research and education needs
being met by today’s internet?
• If not, what should we do?
History, cont.
October 1996 I2 organizing meeting
• 34 institutions in attendance; all 34
signed up
Membership commitment
• $25,000/year in membership dues
• I2 connectivity and campus upgrades

Today’s Internet
Growing at 10 - 15% per month
Challenges to higher education
• The “world wide wait”
• Human interaction awkward
• Virtual meetings and seminars
• Shared authoring
• Browsing publications
• Distributed large scale computing and data base
efforts not feasible
Today’s Internet
Inadequate for mission-critical
applications
• Authentication
• “Best efforts” not good enough
Intranets and Extranets instead
• Match capacity and demand
• Provide a more secure environment
• Don’t reach the public at large, though!
Barriers to Progress
Providers swamped attempting to
match capacity to demand
Advanced applications can’t be
deployed
No large scale development
environment available
Negative-sum competitive
environment inhibits investment
Advanced Internet
Projects
Next Generation Internet (NGI)
• Focused on:
• Federal mission agency needs
• Maintaining US Internet leadership
Internet2
• Focused on:
• Higher education needs
• Moving the public Internet to the next level
Advanced Internet
Projects
The whole is greater than the sum of
the parts
• NGI provides partial financial support for
university Internet2 projects
• Internet2 and NGI coordinate technology
development and deployment
• Industry has strong incentive to implement
resulting capabilities
Application Attributes
Large-scale, multi-site computation
and database processing
Real-time access to remote scientific
instruments
Interactive research collaboration
and instruction
Shared virtual reality
Any combination of the above

Internet2 Mission
Facilitate and coordinate the
development, deployment, operation
and technology transfer of advanced,
network-based applications and
network services to further U.S.
leadership in research and higher
education and accelerate the
availability of new services and
applications on the Internet.
Internet2 Goals
Enable new generation of
applications
Re-create leading edge R&E
network
capability
Transfer capability to the global
production Internet
Applications Priorities
Focus on content
• Educational
• Research publications
• Mass media -> personalized media
Attack middleware challenge
• Seek 100% coverage of interoperable scalable
middleware
• In collaboration with industry members
Applications and Engineering
Applications
Motivate

Engineering
Network Requirements
End-to-end performance guarantees
• Across multiple providers
Application-based performance
Authentication & security
New business models
• Performance related pricing
Single-Lane Road ->
Multi-lane Superhighway
• Special-purpose lanes
• Access control
• Tolls where appropriate
Solutions
Quality of Service (QoS)
• Enable advanced applications without
brute force
• Multi-cloud and multi-provider
Support for Internet-based broadcast
• Scalable
New middleware:
• Connect network to application
• Support application-based charging
• Authenticate users
Support for large delay - bandwidth
products
Bigger pipes
Internet2 Values
in the QoS area
Support applications
Ensure multi-cloud (multi-carrier)
QoS
Ensure multi-vendor (open
standards) QoS
Quality of Service Challenge
A
B
• Does the QoS approach support the applications?
• Are there implementations that work? Only one?
• If cloud ‘A’ and cloud ‘B’ both implement QoS, does the
combined A+B catenation implement QoS?
