Measuring the success of the next generation Internet

21.06.2004



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.



The measurement system is a lightweight software solution that can be easily deployed into various parts in the network and in end-systems, including handheld mobile devices. "An important part is the configuration of the probes, and how to specify what to measure," furthers Roth.

The system was developed in joint partnership between partners from industry and research. Coordinated by Hitachi Europe, France Telecom R&D, Consulintel, S.L. and Fraunhofer FOKUS make up the other partners in 6QM. The involvement of Hitachi Ltd. Japan underlines the global importance of research issues addressed in the project.

Public presentations of the system in various application scenarios have taken place to demonstrate the viability of the measurement approach. The quality of multimedia streaming over satellite links was measured and presented at Cebit Hannover and Global IPv6 Summit 2003 in Madrid.

Another demonstration at 6NET Spring Conference, held in Brussels on 18-19 May 2004, showed how the 6QM system can test the quality of service in an online gaming context. The system was used to measure the delay between the game server and players located in Madrid, Brussels, Berlin and Tokyo. Such information can be used in order to give better fairness to online gamers by compensating for differences in the delay experienced by the participating players.

Researchers from 6QM are actively participating in the Internet Engineering Task Force (IETF) to develop standards for QoS measurement. "A major part of the work [at 6QM] is to contribute to upcoming standards," says Roth and he describes the measurement system as a "necessary piece in the whole picture" for the progress of IPv6.

The project will also look into how to perform measurements across multiple administrative domains and further research into how to best configure the probes and how to scale high volumes of measurement data. The 6QM project will concentrate on scenarios in home automation networks to demonstrate the system’s applicability to future technologies.

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...

Im Focus: Room-temperature multiferroic thin films and their properties

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
