1. Internet2 Overview
By Lee Perlis
Membership Services Manager
Brandeis University
This is a general overview presentation about Internet2. Internet2 is a consortium, led by US universities, which is recreating the partnership among academia, industry and government that fostered today’s Internet in its infancy.

2. Internet2 FAQ What (and why) is Internet2?
Will Internet2 replace today’s Internet?
Will there be an Internet3?
How (or when) can I connect to Internet2 from home?
What’s your stock ticker symbol?
These are some commonly asked questions that this presentation will answer.

3. People on the Internet Millions of People
This chart shows the rapid rise in the number of people using the Internet. The projected figures are probably conservative.

4. Computers on the Internet
Millions of Computers
This shows the number of computers on the Internet. Increasingly, however, non-computer devices will be connected to the Internet, and the total number of devices—computer and non-computer—will rise much more rapidly than the number of computers. The size of the Internet has doubled every 11 months since its inception and this rate will only increase in the future.

5. Yesterday’s Internet Thousands of users Remote login, file transfer
Applications capitalize on underlying technology
These are some important characteristics of the Internet during its pre-commercial development.
4/10/2019

6. Today’s Internet Millions of users
Web, , low-quality audio & video
Applications adapt to underlying technology
Since commercialization in 1994, key characteristics of the Internet have changed: the size of the network and the capacity applications require support beyond the original design parameters of the underlying technologies.
4/10/2019

7. Tomorrow’s Internet Billions of users and devices
Convergence of today’s applications with multimedia (telephony, video-conference, HDTV)
Interconnect personal computers, servers, and imbedded computers
New technologies enable unanticipated applications (and create new challenges)
Tomorrow’s Internet promises even more demands: many more users and even more demanding applications. New capabilities must be developed to realize the potential of tomorrow’s Internet.

performance gap
However, there are significant divergences among these three things:
The potential of the technology: what the entire network could do if the underlying technologies worked together in an optimal way.
Actual performance: the real-world performance an end-user sees
Hype: the performance we’d have if all the press releases and marketing materials were true.

9. Today’s Internet Doesn’t
Provide reliable end-to-end performance
Encourage cooperation on new capabilities
Allow testing of new technologies
Support development of revolutionary applications
Today’s Internet has serious shortcomings. Some of them are performance or technically related, which limit the kinds of applications and capabilities the Internet can support. Other limitations affect the ability to innovate new capabilities that would address some of the performance and technical limitations.

11. What Is Internet2?
A project of the university community working with our corporate colleagues and government to close the gap between the potential and reality of the Internet
4/10/2019

12. Why Internet2? The Internet was not designed for:
Millions of users
Congestion
Multimedia
Real time interaction
But, only the Internet can:
Accommodate explosive growth
Enable convergence of information work, mass media, and human collaboration
Internet2 is focused on the Internet’s potential for our future
4/10/2019

13. Why University Leadership?
The Internet came from the higher research university community
Stanford -- the Internet protocols
NSFNet -- the scaled-up Internet
CERN -- The WWW protocols
University of Illinois -- The Web browser
Research universities require an advanced Internet and have demonstrated they can develop it

This spiral represents one way of looking at the development of the Internet. As the Internet moved from a research project to a commercial service, a set of partnerships fostered its development. During this process, the Internet grew in a number of ways: size, complexity, bandwidth, etc. Internet2 is forming the partnerships needed for technologies in a second cycle of innovation make their way into the commercial Internet.

This is the Internet2 mission.
4/10/2019

16. Internet2 Goals Enable new generation of applications
Re-create leading edge R&E network capability
Transfer technology and experience to the global production Internet
These are the three primary goals of Internet2.

17. Organization: Membership
Regular members: 199 U.S. research universities
Corporate members: 70+ companies
Affiliate members: 30+ non-profits supporting Internet2

19. Internet2 Focus Areas Advanced Applications Middleware
Advanced Network Infrastructure
New Network Capabilities
Partnerships
These are the five areas that Internet2, Internet2 members, and partner organizations are focused on.
4/10/2019

20. Advanced Applications
Distributed computation
Virtual laboratories
Digital libraries
Distributed/Distance learning
Digital video
Tele-immersion
All of the above in combination
Advanced applications come in many flavors, and those flavors can be combined. Advanced applications share the characteristic that they require advanced network capabilities to work—they either don’t work at all, or won’t work well on today’s Internet.
Enabling advanced applications is at the heart of Internet2.

21. Virtual Laboratories Real-time access to remote instruments
University of Pittsburgh, Pittsburgh Supercomputing Center 3-D Brain Mapping
This application links an MRI machine with a supercomputer to produce 3-D visualizations of the neurons in a patient’s brain firing in real-time. The resulting animation can be viewed by any doctor that has access to high-performance networking. These capabilities transform the process of visualizing a patient’s brain—a process that normally takes days—and allows doctor’s to work in ways not previously possible.

22. Virtual Laboratories Real-time access to remote instruments
University of North Carolina, Chapel Hill Distributed nanoManipulator
This is an application which allows remote control of an electron microscope that can actually move molecules around. The application also provides “force feed-back” to the remote operator.

24. Virtual Laboratories
Space Physics & Aeronomy Research Collaboratory (SPARC)
University of Michigan
NSF
Space Physics Aeronomy Research Collaboratory (SPARC) developed at the University of Michigan--allows researchers access to data from instruments from around the world (including Greenland) w/o having to travel there, and allows them to discuss and interact in real time.
It also allows them to combine data from instruments around the world to enable science not previously possible.
This applications allows access to broader audience, including the second-order affect of enabling graduate students (who would never have been able to go to Greenland) to look in on research.

Tele-immersion
Shared virtual reality
University of Illinois at Chicago Virtual Temporal Bone
This is a program that allows a doctor to share a 3-D image of a complex piece of anatomy (the inner ear) with students in a way that makes teaching the anatomy much easier. By making this interactive capability available over the network, a doctor can teach students remotely.

26. Tele-cubicles and the CAVE
Tele-cubicles and CAVEs are different interfaces used for some advanced applications. Immersion in a virtual world, or interaction among people using these interfaces allows people to interact with applications in new ways. The requirements of network applications using these kinds of displays generally require advanced networking.

27. Distributed Computation
Large-scale computation
University Corporation for Atmospheric Research
This visualization is the result of a computer model for a cyclone developing over Asia. It is the result of combining computing resources and data physically located around the country. It allows meteorologists to provide longer-range and more accurate forecasts, thereby giving people more advance and more accurate notice of potentially dangerous and damaging weather.
