IB in the telecom industry
- How to deal with botnet components in the provider's network
DDoS attacks using botnets are a headache for network operators. We discuss the most popular attack vectors: “classic” flood, smurf-attack and ping-flood. Also tell you how to prevent them.
- Botnet "spamming" through routers: who came under attack
Last year, information security specialists discovered a malware that attacked 400,000 routers. The targets were devices with the activated BroadCom UPnP function. Read the article on the mechanisms of infection: the ports used and the tools of the virus.
- American telecoms will fight phone spam
Cellular operators in the United States are introducing subscriber authentication technology - the SHAKEN / STIR standard. We describe the principles of the protocol - the article has a flowchart and code examples from the GitHub repository of American telecom.
- DDOS and 5G: thicker "pipe" - more problems
DDoS attacks are a threat to IoT and 5G. The material tells about two methods of protecting networks of Internet providers and cellular operators: comprehensive traffic clearing centers and a budget option with integrated security systems.
Network technologies
- SDN will be launched into space: why is it necessary
Temporospatial SDN is a system for scanning software-defined networks in orbit. It will manage the satellite infrastructure and aerostats that distribute the Internet to remote corners of the planet. How the system works and what difficulties the developers have yet to solve - read the material.
- Technology that will bring quantum networks closer
An international group of physicists was able to develop a quantum follower that can (unlike analogs) work at room temperature. It can be the key to scanning global quantum networks. We describe what innovation is about and discuss other technologies that approximate the creation of the quantum Internet — artificial diamonds for the transmission of qubits and error correction algorithms.
- Engineers "twisted" the light in the fiber: why it is needed
Australian engineers have proposed to encode the light in the optical fiber using the photon spin. In theory, technology will increase the capacity of networks by a hundred times. It can happen in the next two years. The article focuses on system components, materials used (for example, antimony telluride) and principles of operation.
- 500 Gbit / s - record speed in fiber optic networks
German researchers for the first time achieved a data transfer rate of 500 Gbit / s in "field" conditions. For this, they developed an algorithm for probabilistic formation of a signal constellation (Probabilistic Constellation Shaping, or PCS). The material will tell about the principles of probabilistic modulation and its analogue - geometric modulation.

Standards
- Implementing IPv6: FAQ for Internet Providers
We analyze the most popular issues that telecoms operators have during the transition to IPv6: about potential problems with hardware and hardware.
- The new standard based on PCIe 5.0 will “connect” CPU and GPU - what is known about it
This year comes Compute Express Link - a standard that will provide high speed data transfer between components of heterogeneous systems (CPU, FPGA and GPU). In the article - the details of the specification, technical parameters and shortcomings of the standard, which are noted by experts of the IT industry. We'll also talk about analogs - CCIX and GenZ standards.
- Announced USB4: What is known about the standard
Devices based on USB4 will appear only by 2021. But some characteristics of the standard are already known: a capacity of 40 Gbit / s, the ability to simultaneously charge and display an image. We discuss what can go wrong.
- IPv6 protocol - from theory to practice
We compare Russian and foreign experience in the implementation of IPv6 in IoT networks and industry. We discuss approaches to migration and the experience of the application of this protocol by various organizations.
IT legislation
- The battle for network neutrality - a chance to return
A fresh article that continues our series of posts about Net Neutrality. It will be a question of the new bill - the act “On saving the Internet”, which will have to “roll back” the rules of network neutrality to the 2015 state. We present the opinions of representatives of the government and industry, talking about the prospects for the initiative.
- Situation: Japan may limit downloading content from the network
Japanese authorities are proposing to adopt a bill that will prohibit users from downloading all files protected by copyright from the network. Read about the reaction of Japanese publishers, content makers, scholars and lawyers - read the article.
- Free Wi-Fi according to the law.
This is a practical guide to deploying hotspots in public places. We tell what to look for in order not to break the law. You will also find here recommendations on the choice of equipment.
