Internet applications across the globe are currently being re-engineered in anticipation of the transition to Internet Protocol version 6 (IPv6) from version 4 over the next three to four years. But before companies can make their IPv6 products commercially available, they will have to thoroughly test performance, standards-compatibility and interoperability.
The IP protocol, or standard, allows internet users to use different software applications and technologies when accessing the network. While plenty of commercial software already exists to test complex telecom protocols, these are often proprietary and all are expensive. For example, a GSM test system can cost about €2 million.
The researchers on the EU-funded Go4IT project have developed software suites and services that dramatically lower the cost of such testing for Europe’s businesses by providing IPv6 test suites available for free from the project’s website site.Other test software developments
DHCP is a protocol that automates the assignment of IP addresses and other parameters to networked devices.
TTCN-3 is a computer language developed to test telecommunications software. The specification has received the backing of major commercial companies, including Ericsson and Nokia.
Go4IT’s TTCN-3 test suites will also be useful to a range of other industry sectors, such as car manufacturing.
The Go4IT project team’s work has won the interest of government test centres in China, the US and India, which also face the challenges of IPv6 transition.
In a further initiative, the Go4IT team has established a global open source community devoted to the development of TTCN-3 tests. The community includes researchers at universities in Inner Mongolia and Uruguay.Encouraging the transition
The open source approach to TTCN-3 development allows small and medium sized enterprises and academics to easily participate in the development of the standard without facing prohibitive cost barriers.
“At the beginning of the project we saw that there was strong interest in TTCN testing and no free tools available,” says Go4IT project coordinator Franck Le Gall. “Our open source components for TTCN-3 testing are just a starting point.”
The transition to IPv6 from IPv4 is necessary because the internet is running out of addresses, he says.
“Of course, as IPv6 was engineered after IPv4, some other improvements have been built in,” says Le Gall, who participated last year in Europe’s impact assessment of IPv6 and is a manager with European strategic management consultants, the inno group. “But the need for more address space is the one compelling reason for the transition.”
The move from IPv4’s 32-bit addressing system to IPv6’s 128-bit system provides for virtually unlimited IP addresses and a greater flexibility in addressing systems.
The internet community incorporated IPv4 after agreeing to the standard in 1981, before anyone even dreamed about the scale of today’s internet. IPv4 has a 32-bit addressing system, allowing the creation of almost 4.3 billion individual addresses.
By 1991, it was clear that 4.3 billion addresses would be insufficient for any global internet. By 1996, the standards setters designed the main components of IPv6 and started working on the challenges of implementation.
While preparation for the transition has taken a long time, more and more manufacturers are building IPv6 compatibility into the server equipment and software that handles global internet traffic.

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...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
