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.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
