In software and mathematics that can make online communications via computer, mobile τηλεφώνων ή δορυφόρων κατά πολύ ταχύτερες και ασφαλέστερες από ό,τι είναι σήμερα, δουλεύουν researchers του Aalborg University, του ΜΙΤ και του Caltech.
The specific study χρησιμοποιεί ένα τετράλεπτο mobile video ως παράδειγμα: η μέθοδος που χρησιμοποιήθηκε από τους δανούς και αμερικανούς ερευνητές είχε ως αποτέλεσμα το download του πέντε φορές πιο γρήγορα από ό,τι μέσω σημερινής state of the art τεχνολογίας, ενώ παράλληλα το streaming του έγινε χωρίς διακοπές (τη στιγμή που μέσω «συμβατικής» μεθόδου κόλλησε 13 φορές).
This technique could bring dramatic changes to the market and to the Internet in general. "In experiments with our network coding in Internet traffic, equipment manufacturers found speeds that were five to ten times faster than usual. And this technology can be used in satellite communications, mobile communications, and regular online computer communications, "says Frank Figeck, a professor at the Aalborg University Electronic Systems Department.
Communication through Internet formats the data into "packets". Error checks ensure that the signal arrives in the correct format, but it also often means that some 'packets' have to be re-sent, which has the effect of slowing down a network. Danish and American researchers solve this particular problem with a special type of network coding that uses innovative mathematics to store and Mission of the signal in a different way. The advantage is that the resulting errors do not entail the need to resend a "packet" - instead, the upstream and downstream data are used to recreate the lost data through a mathematical equation.
With conventional systems, it is possible to send an 1 package, an 2 package and so on. In this case, this is replaced by a mathematical equation. As Figueck explains, a good comparison would be with cars on a street: "we do not need red traffic lights. We ship cars at the junction from all directions, without having to stop one for the other, which results in faster flow of traffic.
Network coding is recommended for use in the Internet of Things, 5G, software defined networks, content centric networks and possibly distributed storage solutions. However, to function, coding and decoding of data is required through dedicated, patented technology. Fecek and his two former students from Aalborg University (together with their colleagues from the United States) founded the Steinwurf software company, which makes Random Linear Network Coding (RLNC) available to manufacturers hardware - while, as noted in a relevant university announcement, secret negotiations are under way to bring this technology to consumers at some point. As part of this effort, the company has opened offices in Silicon Valley (however its headquarters are still in Aalborg).
