Processing Big Data in QoE Stor

VAS Experts' clients are telecom operators providing services to end subscribers, who in turn generate traffic. To effectively manage this data flow, the VAS Experts team has developed a traffic monitoring and analysis system, Stingray Service Gateway (SSG), which allows operators not only to analyze traffic, but also to offload statistics. As the number of subscribers increases, operators receive more and more data, which complicates the process of data storage and processing. In this article we will consider in detail how information is processed and stored in the SSG statistics server - QoE Stor.

What DDoS attacks are and how a telecom operator can protect against them

A Distributed Denial of Service (DDoS) attack is a cyberattack that aims to render a resource, such as a website or network service, unavailable to its legitimate users. This is achieved by overwhelming the target system with an enormous number of requests that exceed its processing capabilities.
