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.
Go4IT received funding from the EU's Sixth Framework Programme for research.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
