IPv6 will play a key role in the next generation Internet. It promises to deliver better quality services than the existing Internet, but how can we be sure? IST project 6QM was set up to ensure service providers deliver what they promise.
The 6QM project has developed technology to measure the quality of service (QoS) in IPv6 networks. "A prominent feature that we are concentrating on in our measurement system is the capability to perform passive flow measurement," says Rudolf Roth, project partner and senior scientist at Fraunhofer FOKUS.
"When a service provider offers a certain quality of service it is necessary to validate that the promised quality is actually delivered. The system tests this by observing the actual traffic flowing through the Internet, to give an accurate picture of the service being delivered," adds Roth. Measurement results can be displayed graphically so it is easy to see if the quality of service meets the agreed service level agreement.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion
Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...
Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
