If this new technique gets implemented your Internet speed is going to jump. It’s a mathematics based technique crafted by researchers at Aalborg University, MIT and Caltech; the nodes of a network are upgraded to turn them into smarter nodes. This technique makes the connection more secure and will soon be integrated into 5G mobile networks, Internet of Things and satellite communications.
Since 1970s TCP/IP is being used for internet data transfer, and the transfer occurs in packets of information. Now the time has come to upgraded this system; because the major flaw in this system is that if any packet goes missing the transfer rate slows down and in turn it hampers speed. Other issue is that packets take the same route thus allows for the transmission to be intercepted quite easily.
By way of Network coding the nodes of the network can be upgraded. The nodes in network coding can be enabled for re-routing, re-encoding and elaborating packets whenever a need arise. This smartness leads to unparalleled flexibility. This system offers a lot better speed and security than TCP/IP.
Professor Frank Firzek who led this research stated; ‘In experiments with our network coding of Internet traffic, equipment manufacturers experienced speeds that are five to 10 times faster than usual. And this technology can be used in satellite communication, mobile communication and regular internet communication from computers.’
In this system each node deals every packet as a number (binary number of course) and a set of linear equations is made by using numbers pulled from the data and randomly generated set of coefficients. So each linear equation will personify a coded packet where the header will be made up of coefficients and the variables will be the content of the packet.
So, in a crux, each coded packet will carry partial information on a number of the ‘unaltered’ packets at once but multiplied with different coefficients. This system offers a more secure connection because a person trying to to hack the data stream would require access of all the packets in order to decode the information.
Another plus-point is that packets travel in different paths to the recipient and this renders a highly efficient system that is speedy and secure.
