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

Internet2 - Overview

187 University Members

Over 70 Internet2 Corporate Members

Over 40 Affiliate Members

Over 30 International Partners

Internet2 Mission

Develop and deploy advanced network applications and technologies, accelerating the creation of tomorrow’s Internet.

Why University Leadership?

The Internet originated in the higher education community

• Stanford – the Internet protocols• NSFNet – the scaled-up Internet• CERN – The WWW protocols• University of Illinois – the Web browser

Universities require an advanced Internet and have demonstrated they can develop new Internet capabilities

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 Network Infrastructure Today

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 (goal)

Internet2 Backbone Networks

Tomorrow’s Internet

Billions of users and devices

Convergence of today’s applications with multimedia (telephony, video-conference, HDTV)

Support mission-critical applications

Interconnect personal computers, servers, and embedded computers

New technologies enable unanticipated applications and create new challenges

Internet2 December 2003

10 Gigabits per second backbone

Optical transport capability (Lambda) using DWDM

Flexible provisioning to support point to point optical connection

Native IPv6 deployment concurrent with IPv4

What We Have Learned

•High performance infrastructure is a necessary but not sufficient ingredient of high performance network capability

•Middleware is required to scale up advanced network capabilities and applications

•The Internet marketplace is slow to deploy advanced capabilities

•The biggest challenges are organizational, not technological

What we are doing

•End-to-End Performance Initiative

•Internet2 Middleware Project

•Expanded Access

End-to-End Performance

When it’s built can it deliver?

The negative feedback loop

Ensure that the infrastructure is delivering to its full potential

Facilitate and coordinate communications

Context for E2E Performance

High performance backbones are in place.

Now, under certain conditions within particular regional and local network environments, we can experience the full benefit of this infrastructure in the development and use of advanced applications.

Context, cont.

However, most of us experience a significant gap between the reality and potential of the national high-performance networking infrastructure.

The Mission

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.

First Step

Workshop in Ann Arbor on 9 January, 2001

• 40+ participants• Each participant provided a short paper on “What does E2EPerformance Mean?”

• Planned agenda was not used in order to respond to more pressing issues from participants.

• Design team formed to create an overall vision paper.

Summary of Discussion

Input focused on both technical and human factors:

• Developing people infrastructure to support performance initiatives

• Managing communications and managing expectations

• Developing the measurement architecture, analysis standards and deploying them consistently

• Creating clearer definitions of “performance”

Areas of the Initiative

Applications

Host/OS Tuning

Measurement Infrastructure

Performance Improvement Environment (PIE)

Operations and Human Communications

Performance Evaluation and Review Framework (PERF)

Applications

•Work with specific application communities to help solve their performance problems.

•Use a few key, general purpose applications for performance testing.

Host/OS Tuning

•Provide Best Practices for getting the most from your computer.

•Locate or build tools for Host/OS performance diagnostics.

•Work with computer vendors on Internet2 Performance Packages.

Measurement Infrastructure

•Bring together current measurement efforts and projects in the community.

•Establish an End-to-End Measurement Infrastructure from the intersection of these works.

•Create diagnostic tools to determine the health of the network and locate performance problems.

Operations and Human Communications

Establish communications among common interest groups

• System administrators• LAN administrators• Campus NOCs• GigaPoP• Application support staff

Establish communications between groups for operations and problem resolution.

Performance Improvement Environment (PIE)

•Develop a dynamic environment where collaboration and information sharing will happen.

•Identify, collect and disseminate appropriate information for end-to-end related issue.

•Include success stories,measurement statistics, reference materials, measurement tool documentation.

•Include pointers to materials already developed by other communities.

Performance Evaluation and Review Framework (PERF)

Establish a framework for resolving performance problems

• Provide known solutions by using the PIE• Tap community knowledge by facilitating group communications

• Coordinate a team of experts to solve hard problems

Internet2 Organization Role

Staffing• Cheryl Munn-Fremon, Initiative Director• Russ Hobby, Technical Architect• George Brett, Information Architect• Lisa Wilberding, Communications Coordinator• Terri Saarinen, Program Assistant

Internet2 Organization Role cont’d.

Funding• Facilitate seeking sources of funding• Internet2 will invest about $1.5 million per year

Communications coordination• Web site• Workshops, meeting presentations, …

E2E Performance Improvement Environment (pie)

•Performance Improvement Environment• aka The Knowledge Base• a repository • a collaboratory • living and archival documents • connections to other resources

E2Epie – Background

• E2E Design Team White Paper:• Called for “A web-based information system / knowledgebase… to function as a distributed document and resource repository.”

• Elements should include: documentation, training materials, information resources, downloadable tools, mechanisms for discussion groups, links to related resources, contact information

E2Epie – Background (continued)

• E2Epie principles and guidelines:• Provide active leadership and facilitation.• Build trust.• Create an economics of recognition.• Leverage existing resources.• Think big and start small.

• Major components• People to people (directories & collaboration space)• People to content (directories of projects & tools, Case

studies)• Problems to solutions (knowledgebase, expertise

connection)

E2Epie – Current Status

• Developing web site content to reflect recommendations of the Design Team and Consultant documents.

• http://www.internet2.edu/e2epi/

• Actively looking for supporting materials and resources to include in web site.

• Mail to: info-E2Epi@internet2.edu

E2Epie – next steps

• Begin collecting stories.• Using interviews and other channels we will begin collecting

stories about performance improvement issues.

• We will work with EDUCAUSE Effective Practices and Solutions database for publishing the E2Epi stories.

• Identify and collect information about projects, resources, and tools.

• With help of Technical Advisory Group and other E2Epi participants we will make sure to have up-to-date and correct information.

• Explore resources and tools for collaboration efforts.• Discussion forum: http://e2edev.internet2.edu/discus/
