The National Institute of Standards and Technology (NIST) is establishing a testing program to assure that the U.S. government purchases new computers and networking products that work properly on the next-generation Internet traffic system while meeting standards for federal government use.
Addressing the U.S. government standards profile known as USGv6, the testing program is heralded by a new publication, a preliminary set of tests and an upcoming meeting to discuss its management.
Every device that is connected to the Internet, from a supercomputer to a smart phone, has a unique numerical ID known as an Internet Protocol (IP) address. However, the number of computers and mobile devices with IP addresses is closing in on the nearly 5 billion address limit of the prevailing Internet Protocol, known as IP version 4 (IPv4). To meet the challenge, the computer industry is gradually moving to IP version 6 (IPv6), which is believed to have an inexhaustible address space. IPv6 can accommodate 2128, or more than 340 undecillion (a number followed by 36 zeros), sites. To imagine this, picture each known star in our universe with trillions of IP addresses.
The USGv6 profile also endeavors to “raise the bar” on the security capabilities of IPv6 devices connected to the Internet.
In its first step to prepare for the move to this new protocol, NIST in 2008 released a standards profile for U.S. government implementation of IPv6, which is now known as USGv6. The document, NIST Special Publication (NIST SP) 500-267, assists federal agencies in procuring USGv6 networking products.
NIST scientists, in concert with industry partners, have been developing testing procedures to assure that computers, routers and other equipment conform to, and are interoperable with, the IPv6 capabilities specified in the profile.
To help create the test infrastructure necessary to support broad USGv6 initiatives, NIST has taken three major steps: Publishing NIST SP 500-273, IPv6 Test Methods: General Description and Validation, a document describing the USGv6 Test Program procedures for validation and accreditation of test methods; developing a preliminary set of abstract test suites, and scheduling a meeting on May 27, 2009, to discuss program implementation issues.
“This testing regime is important,” explains NIST computer scientist Stephen Nightingale, “to ensure that future USGv6 procurements are both sufficiently capable and interoperable.”
More information on the USGv6 publications and testing program is available at www.antd.nist.gov/usgv6/testing.html. All comments should be sent electronically to firstname.lastname@example.org.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
