New generation 3r33232 networks.
How 5G networks will change DDoS attacks
3r3308. With the advent of 5G, the number of DDoS attacks is expected to increase significantly. At the same time, on estimated Kaspersky Labs, one DDoS attack on a communications service provider costs a small and medium business $ 120 thousand. The article talks about two solutions that will protect the network of providers from botnet attacks. 3r33333.  
Launched the world's first commercial network 5G 3r3333310.
3r3308. It was launched by the Finnish operator Elisa. According to the test results, the download speed in the new network was 1 Gbit /s. However, the global distribution of new-generation networks is not worth waiting for until 2020. The article describes how telecommunications companies and mobile device manufacturers are preparing for the 5G era and what technologies they are developing: from phased antenna arrays in smartphones to beam forming systems with machine learning in data networks. 3r33333.  
Virtualization of mobile network functions - why is it important for 5G

3r3308. This is a material about virtualization technologies that “come” to the networks of cellular operators: function virtualization, electronic SIM cards, and MNaaS services. We are talking about their merits and potential problems from the point of view of information security. 3r33333.  
5G can replace cables - but not everywhere 3r3333310.
3r3308. There is an opinion that 5G-networks will oust cable Internet providers from the market. We understand which areas of the new generation network will indeed be able to replace cables, and where the “wired” connection will remain for a long time. 3r33333.  
Programmable valve arrays: how they will help networks 5G

3r3308. This article is a review of the Versal FPGA chip architecture from Xilinx. The chip should improve the signal in 5G networks by optimizing the radiation pattern of mobile communication antennas. We tell how it is arranged and on what technologies it is built. 3r33333.  
On information security and botnets

3r3-300. A botnet was detected that “spammed” through routers 3r33333.
3r3308. In the autumn of 201? security specialists discovered a malware that infected about 400 thousand devices. The targets of the attacks were routers with the BroadCom UPnP feature enabled. We describe how a botnet works and which devices are subject to attacks. 3r33333.

What is the difference between firewall and DPI-systems
3r3308. We explain how filtering systems work - DPI, ACL, firewalls for FreeBSD - and how they differ. Also we will talk about how these systems are used by providers. 3r33333.  
In addition to IoT: the Mirai botnet began attacking machines on Linux
3r3308. The Mirai attack on IoT devices became one of the largest in 2016. Recently, a new version of the virus has appeared, which is aimed not at the Internet of things, but at Linux servers with Apache Hadoop. We tell what vulnerability uses a botnet and how to close it. 3r33333.  

Internet and network standards 3r33232.
Implementing IPv6: FAQ for ISPs
3r3308. When implementing IPv? providers face a number of problems: from the need to upgrade obsolete hardware to bring all systems in line with the requirements of the law. Here we provide a list of questions and answers with ready-made solutions. 3r33333.  
To replace TCP: QUIC protocol is ready for[но не готов стать RFC]deployment.
3r3308. For two years now, the Internet Engineering Council has been working on a standard for QUIC technology, which should speed up data transfer in wireless networks. The article will talk about how the protocol works and about the services that already support the new technology. Here are some disadvantages that QUIC is not yet ready to become RFC: vulnerability to DDoS, incompatibility with other network technologies and difficult troubleshooting. 3r33333.  
3r3181. How will launch Starlink - satellite Internet from Ilona Mask
3r3308. The article tells how Starlink satellites will communicate with each other and ground stations, how much they will be launched into space and how the network will connect cities in different parts of the Earth. Also talk about what you can expect from this project. 3r33333.  
3r3193. Quantum networks: prospects and challenges of implementing 3r33310.
3r3308. Quantum networks are considered to be almost absolute cryptographic protection, so they are used to create distribution systems of crypto keys. But such solutions have not yet been implemented everywhere. We understand the material that hinders the spread of quantum networks and what difficulties their developers face. 3r33333.  
Quantum networks: what they develop in Russia and abroad 3-333310.
3r3308. A continuation of the previous article dedicated to the first experimental quantum networks: projects of researchers from Europe, China and the United States, as well as Russian quantum communication lines in St. Petersburg, Kazan and Moscow. 3r33333.

Wi-Fi and wireless networks

Announced Wi-Fi 6: what you need to know about the new standard
3r3308. Standard Wi-Fi 6 will be released at the end of 2019. We talk about the new features that the developers provided with it: support for the 2.4 and 5 GHz and OFDMA bands, as well as Target Wake Time, which determines the idle time of the router to save energy. 3r33333.  
How to deliver the Internet in developing countries
3r3308. Wi-Fi-networks, balloons and satellites - all these technologies are used by large companies to connect people from Africa and Asia to the Internet. The material describes a wireless project from Facebook, which uses a mesh topology to deploy Wi-Fi access points in Tanzania, Kenya, Indonesia and other countries. 3r33333.  
Free Wi-Fi: a German court overturned fines for coffee shops for copyright-infringement of customers
3r3308. Since 201? Germany had a law on the responsibility of the owner of a public Wi-Fi access point for pirated content that network users download. This year the document was amended, which abolished fines. We are talking about the potential difficulties that hot spot owners may face in new realities. 3r33333.  
"Expanded boundaries": the 6 GHz band will be provided for the needs of Wi-Fi
3r3308. The Federal Communications Commission proposed to expand the range of frequencies for Wi-Fi and use 6GHz. An article about what the FCC did not suit 5 GHz and 2.4 GHz and how they will prevent malfunctions in satellite communications using a 6 GHz spectrum. 3r33333.
