Lawful Intercept for Mobile and Fixed Networks: Technical Requirements Explained

Lawful interception (LI) is the legally authorized access by law enforcement to the communications of a specific target, carried out by the telecom operator. Technically it comes down to three things: identifying the target's traffic, copying it without the target noticing, and delivering it to the authorities over a defined handover interface. The exact obligations depend on the jurisdiction, so the network design starts from the local legal text, not from the equipment.

Becoming a Convergent Operator: Broadband & MVNO on One Core

A regional broadband provider can add mobile service without building a radio network by launching as an MVNO on a host operator's network. A safe path is to start as a Light MVNO, where the host provides radio, core and SIMs, and move to a Full MVNO with its own packet core, policy and charging once scale justifies it. The main gain of a fixed-mobile bundle is lower churn.

Network traffic classification: what it is, how it works, and what classes there are

Modern networks handle many types of traffic simultaneously: video, voice, online games, corporate services, and background downloads. Each of these has its own requirements for connection quality. For example, stable bandwidth is important for streaming video, while minimal latency and jitter are important for voice services. Background file transfers, on the other hand, can be interrupted without serious damage. If all traffic is processed equally, critical services will quickly begin to suffer from overload.

From classical methods to neural networks: Exploring the potential of Deep Learning in identifying obfuscated traffic

Network traffic analysis and classification have become essential for maintaining the resilience and security of contemporary computer networks. With the rapid increase in data volumes and the growing complexity of encryption methods, the need for effective network flow classification continues to rise. By identifying, categorizing, and analyzing network traffic accurately, organizations can detect potential threats, optimize network performance, and ensure compliance with security protocols.

DNS-over-HTTPS — what is going on with the adaptation

Since the beginning, this protocol has been a very controversial one in the IT community. Some people believe that DoH increases the security of connections, while others think that it only makes the sysadmins’ work more difficult. Either way, DoH is used by more and more applications despite the different points of view. In this article, we will take a closer look at it and tell you what’s really going on.

5 Steps to Become an Internet Service Provider

Maybe there is no point in repeating for one more time that the Internet has become a permanent part of our lives, but it is really interesting to look at the statistical data and make some conclusions from it.
