1. Internet2: building the Internet of the future for academia today
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.

3. Internet2 Goals Enable new generation of applications
Re-create leading edge R&E network capability
Ensure the rapid transfer of new network services and applications to the global Internet
These are the three primary goals of Internet2.

4. Internet2 Focus Areas Advanced Applications Middleware Engineering
Advanced Network Infrastructure
Partnerships
These are the five areas that Internet2, Internet2 members, and partner organizations are focused on.

5. Yesterday’s Internet Thousands of users Remote login, file transfer
Interconnect mainframe computers
Applications capitalize on underlying technology
These are some important characteristics of the Internet during its pre-commercial development.
5/9/2019

6. Today’s Internet Millions of users
Web, , low-quality audio & video
Interconnect personal computers and servers
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.
5/9/2019

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 embedded 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.

8. Directions – Applications
The focus is swinging to high performance applications…..
Collaboration
Remote Access
Very Large Scale Systems
The challenge is scaling and propagating the examples

9. 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.

10. Virtual Laboratories Mauna Kea Observatories AURA University of Hawaii
Here are pictures of various applications already in use:
1) the Upper Atmosphere research Collaboratory (UARC) developed at the University of Michigan--allows researchers access to data from instruments in Greenland w/o having to travel there, and allows them to discuss and interact in real time. 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.
2&3) Pictures of a the output from a scanning electron microscope--allows access to expensive, specialized equipment by students--allows them to control in the microscope and see the output as if they were in the same room
--These both require advanced network capabilities to work--either don’t work, or won’t work well on today’s internet.

11. 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.

12. Middleware
A layer of software between the network and the applications
Authentication
Identification
Authorization
Directories
Security
Middleware is a layer of software between the network and applicaitons

14. Directions -- Middleware
The Internet2 community has responded
Our architects have come together
Our institutions have begun to invest
Our corporate partners have engaged
Distributed authentication
Distributed directory
3rd Quarter 2001 the world begins to change

15. Engineering Quality of Service: QBone Scalable IP Multicast IPv6
Network Security
Network Management
Measurement
These are some of the new network capabilities that advanced networks will need to implement and which the Internet2 community is working on.

16. Internet2 Network Infrastructure
Backbones operate at 2.4 Gbps (OC48) capacity today
GigaPoPs provide regional high-performance aggregation points
Local campus networks provide 100 Mbps to the desktop
This is a broad generalization of the Internet2 network infrastructure.
