In software and mathematics that can make Internet communications via computer, cell phones, or satellites much faster and safer than they are today, work researchers of Aalborg University, MIT and Caltech.
This study uses a four-minute mobile video as an example: the method used by Danish and American researchers has resulted in downloading it five times faster than current state-of-the-art technology while streaming it without vacation (when using "conventional" method it stuck 13 times).
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 suitable for use in the areas of Internet of Things, 5G systems, software defined networks, content centric networks and possibly in distributed storage solutions. However, for it to work, the data needs to be encoded and decoded using the special, patented technology. Ficzek and two of his former students from Aalborg University (Jannus Heide and Morten Wittebeck Pedersen), together with their colleagues from USA, founded the software company Steinwurf, which makes RLNC (Random Linear Network Coding) technology available to hardware manufacturers - while as noted in a related announcement from the university, it is in development secret negotiations so that this technology reaches consumers at some point. As part of this effort, the company has opened offices in Silicon Valley (although its headquarters are still in Aalborg).
