One server instead of a rack: the new Stingray PCEF processes up to 32 million sessions

VAS Experts' development team has increased the performance of the Stingray PCEF product. After optimization, the solution can process up to 110,000 requests per second while serving 32 million active sessions on a single server.

How have mobile tariffs changed, and where does PCEF fit in?

For an operator, the tariff has become a tool for managing demand, load, and revenue. Through the tariff grid, an operator can promote its own services, sell additional traffic, offer premium service priority, connect IoT devices, and put together corporate packages.

On the Company's Inclusion in the EU Sanctions List

We, VAS Experts, wish to share our position regarding the company's inclusion in the latest sanctions list of the European Union. The grounds cited were our production of SORM-class solutions – lawful interception and data retention technology used for operative investigative measures.

Bypass support for LR-LINK network cards is now available in Stingray Service Gateway

We continue to expand the list of compatible equipment! Hardware Bypass functionality is now available not only for Silicom network cards, but also for LR-LINK cards based on Intel chipsets.

NMS as a unified control loop for Stingray

While a network includes a limited number of services, operations are typically based on CLI, SNMP monitoring, and a set of internal scripts. But as the infrastructure grows, the number of components increases, and control points start to spread across different systems.

VAS Experts shares expertise on ISP-level DDoS protection in SafetyDetectives Industry Roundup

VAS Experts has contributed expert commentary to the SafetyDetectives article "The Most Overlooked Cybersecurity Threats and How to Defend Against Them," a roundup featuring industry perspectives on the internal blind spots and false assumptions that continue to expose organizations of every size.

How We Deployed Our Own Mobile Operator Test Lab for Core Network Testing

The mobile core is an infrastructure where all components are tightly interconnected. Changes to a tariff plan can affect how the network processes subscriber traffic: which applications to account for, what to block. That is why many scenarios in mobile solution development cannot be fully tested in isolation.

Functional testing of Stingray BNG using an Ixia traffic generator

In BNG-related projects, not only performance but also predictable system behavior under different conditions is critical. Before moving on to load testing, it is important to verify that the device correctly implements both basic and advanced functions in accordance with RFC requirements. This article explains how functional testing of a BNG was organized using a test environment built according to the requirements of a nationwide telecom operator.

How an Operator Can Scale Without Rebuilding the Network

Modern telecom operators and service providers face continuous growth in traffic and requirements for its processing and analytics. The Stingray platform by VAS Experts offers a solution that not only provides full traffic control at L2–L7 levels, but also allows easy capacity scaling as needed.

Wi-Fi HotSpot in an Operator Network: From Isolated Solution to BNG Integration

Wi-Fi HotSpot has long ceased to be just a public internet access point. For an operator, it is a distinct service with its own authorization logic, billing integration, and the need to comply with regulatory requirements. This article explains how a Wi-Fi HotSpot works at the network level, why it is often deployed as an isolated system, and what changes when it becomes part of a BNG.
