QUILT CIRCLE2020 a Letter from the President
THE QUILT CIRCLE2020 A Letter From the President This 2020 Quilt Circle edition commemorates the 20th Anniversary of The Quilt. The fabric of our research and education (R&E) networking community has never been stronger. While our Quilt community has evolved in new and exciting ways in the past two decades, we have also been faced with a number of challenges which we take head-on and always with the spirit of collaboration. As we address the unprecedented challenges presented by the current global public health crisis due to the COVID-19 pandemic, the work of our members is more important than ever to the missions of their member communities. U.S. higher education institutions rely on R&E networks to give them a competitive edge in the most impactful scientific research initiatives which is essential in this crisis. We connect the educational institutions that support university medical centers and their associated hospitals. R&E networks also connect tens of thousands of other community anchor institutions, including K-12 schools, public libraries, local/state government, research sites, cultural institutions, public safety, and tribal lands. Being responsive and providing vital networking infrastructure and resources right now to address immediate needs is who we are and what we do. R&E networks are part of our nation’s critical infrastructure. This year’s edition of The Quilt Circle showcases several examples of the key role of R&E network members in both providing and facilitating the use-network infrastructure to further scientific discovery and collaborations at higher education institutions of all sizes. -

Broadband for Education: the National Internet2 K20 Initiative’S and WICHE’S Recommendations to the FCC
Broadband for Education: The National Internet2 K20 Initiative’s and WICHE’s Recommendations to the FCC Who are we? Internet2: We bring together Internet2’s world-class network and research community members with innovators from colleges and universities, primary and secondary schools, libraries, museums and other educational institutions, the full spectrum of America’s education community, including both formal and informal education. The National K20 Initiative extends new technologies, applications, and rich educational content to all students, their families and communities – no matter where they’re located. We have had immense success connecting the institutions above – in fact, over 65,000 institutions are now connected to the National Internet2 network – but to realize fully the potential of Internet2 all institutions must have adequate bandwidth. What follows are principles we endorse and urge the FCC to adopt. We divide our recommendations into two interrelated categories: connectivity and e-rate support. Western Interstate Commission for Higher Education (WICHE): WICHE and its 15 member states work to improve access to higher education and ensure student success. Our student exchange programs, regional initiatives, and our research and policy work allow us to assist constituents in the West and beyond. Equitable access to broadband technology and, in particular, technology-enabled education, is among our strategies. At present much of the West, particularly the “frontier West,” has little or no access to adequate bandwidth. Many of our institutions are not among those connected by and participating in the Internet2 K20 Initiative. The principles and recommendations below would remedy this situation. Our recommendations: (1) Connectivity • Elementary schools, secondary schools, and branch libraries should be connected at 100 Mbps to 10 Gbps. -

I: the Conception
Excerpt from: Mayo, Keenan and Newcomb, Peter. “How the Web Was Won,” Vanity Fair, July 2008. I: The Conception Paul Baran, an electrical engineer, conceived one of the Internet’s building blocks—packet switching— while working at the Rand Corporation around 1960. Packet switching breaks data into chunks, or “packets,” and lets each one take its own path to a destination, where they are re-assembled (rather than sending everything along the same path, as a traditional telephone circuit does). A similar idea was proposed independently in Britain by Donald Davies. Later in his career, Baran would pioneer the airport metal detector. Paul Baran: It was necessary to have a strategic system that could withstand a first attack and then be able to return the favor in kind. The problem was that we didn’t have a survivable communications system, and so Soviet missiles aimed at U.S. missiles would take out the entire telephone- communication system. At that time the Strategic Air Command had just two forms of communication. One was the U.S. telephone system, or an overlay of that, and the other was high-frequency or shortwave radio. So that left us with the interesting situation of saying, Well, why do the communications fail when the bombs were aimed, not at the cities, but just at the strategic forces? And the answer was that the collateral damage was sufficient to knock out a telephone system that was highly centralized. Well, then, let’s not make it centralized. Let’s spread it out so that we can have other paths to get around the damage. -
Description of Omnipop for Proposals
Description of OmniPoP for Proposals Summary The OmniPoP is a collaborative effort between 12 of the member universities of the Big Ten Academic Alliance. Together, these institutions have pooled their efforts to create a high performance shared infrastructure based in the Chicago area. This infrastructure was designed to complement and augment the shared fiber infrastructure that the Big Ten Academic Alliance members had previously purchased. The OmniPoP operates a high capacity switching infrastructure that supports 10 gigabit and 100 gigabit connections to its member institutions and equivalent high capacity links to national research and education networks such as Internet2, ESnet, and Starlight. This allows OmniPoP connections to be leveraged to provide services to large data flows in support of multi-institutional cooperative research efforts. Efforts supported today include interconnections between the Large Hadron Collider (LHC) Tier 2 efforts at the member institutions and the Midwest Openflow Crossroads Initiative (MOXI) project which links several midwest regional networks to the GENI backbone. OmniPoP Infrastructure and Peerings The Omnipop infrastructure consists of a redundant pair of 100 gigabit capable switches. These switches operate from geographically diverse co-location facilities within the Chicago metropolitan areas. These facilities also serve as Points of Presence (PoPs) for other major networks such as Internet2, ESnet (Department of Energy’s Energy Sciences Network), and Starlight (the international peering exchange), enabling seamless cross connections to the major national and international research and education networks that support much of the academic research community. An additional benefit to these facilities is that they offer the opportunity for Big Ten Academic Alliance members to co-locate additional network related equipment in support of their own projects independent of the OmniPoP core infrastructure. -

Illuminating Diverse Research
An nren case study by illuminating diverse research It’s not easy to read when it’s dim; you need a bright light to see properly. The same is true for scanning the details of microscopic objects – the brighter the light the better, and the Canadian Light Source (CLS) in Saskatoon is one of the brightest light sources around. As a national research facility, CLS produces intense beams of X-ray, ultraviolet, and infrared light for research in a highly diverse set of fields: biomedicine, palaeontology, chemistry, anthropology, material science, biology, quantum research, and agriculture, to name a few. The light from CLS is one million times brighter than the sun and enables many scientific experiments to be run simultaneously. But capturing the giant amounts data created by these experiments has always been a challenge. Hard drive history Diverse discoveries Many CLS experiments create huge multi-dimension The exploration and big data science of CLS is being data sets of samples under study by capturing high- used to watch precisely how batteries chemically react, resolution views of an object at high speed.
