Earlier, the mass media reported on similar initiatives in Russia, where one of the deputies of the State Duma advocated the introduction of registration in social networks by passport. Rumors about proposals to oblige Ukrainians to buy SIM cards based on their passports circulated as early as last year. And the relevant bill has already been submitted to the Verkhovna Rada.hone owners and 9% of owneA team of researchers rks by 10 times, without spending money on the number of wireless access nodes or expanding the signal spectrum. This research will have a significant impact on the performance of LTE and WiFi networks. In fact, the innovation, named "encoded TCP (TCP/NC)", is to completely eliminate the time delays caused by the loss of data packets. In wired networks,
Packet loss is very rare, but in the case of wireless networks Ecuador WhatsApp Number packet loss ranks first among the factors that reduce throughput. According to Technology Review, packet loss in WiFi networks averages 2% of all transmitted data, and for example, on a high-speed train, the share of loss can reach 5%. The diagram shows the decrease in data transmission speed in the TCP network, depending on the number of lost packets: Evand require resending. Encoded TCP assembles packets into blocks and transforms them into algebraic equations describing these packets. If part of the data is lost, the receiver can solve the equation and derive the lost data from it. The process of solving equations is "simple and linear", not requiring complex calculations from a router, smartphone or laptop.
The TCP/NC protocol uses linear equation network coding. Each byte and each packet in a TCP stream is multiplied by a factor from the Galois field F256 and fitted into a linear equation. It is no longer packets that are transmitted through the network, but degrees of freedom. Accordingly, if one packet is lost, it can be restored from known values, that is, from neighboring packets. As applied to TCP, this principle is shown in the illustration: In the course of tests, encrypted TCP allowed to significantly speed up data transmission. MIT researchers found that campus WiFi (2% loss) accelerated from 1Mbps to 16Mbps. On the high-speed train (5% loss), the Intire the implementation of so-called forward error correction, which is what encoded TCP is. Of course, connection acceleration can be expected only if there is packet loss. In other cases, encoded TCP will not be able to increase the speed.
