Professor Mikel Izal from the Public University of Navarre, Basque Country, has analysed the problems to integrate new optic networks in actual network and transfer level (TCP/IP) Internet protocols. This integration will enable to create the core of the second Internet generation in future, the so called Internet 2.
In that area, technological innovations are created everyday and the thesis has been focused on the burst switching networks corresponding to the second optic Internet generation.
Nowadays new optic technologies are based on wavelength division multiplexing. That way, several channels are transferred in a single optic fibre by using different wavelength carriers. Those optic technologies are divided into three generations. The first generation is based on wavelength division multiplexing (WDM). Here it is possible to create high capacity link networks between actual IP routers. The second one offers the possibility to make some operations of direct switching via optic technology. That way, the core of the network may offer optic channels, named Ligthpaths, or it can switch data in large packages, named burst switching networks.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
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...
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...
