DPI - Channel Congestion Control (Optimizing uplink channel)

In this video, we explain how VAS Experts uses DPI (Deep Packet Inspection) technology to optimize uplink channels and manage network congestion during peak hours. You’ll see how traffic is classified into different priorities, how bandwidth is allocated to ensure smooth streaming, web browsing, and video calls, and how telecom operators can save costs without compromising the quality of experience for users.

Migration from Sandvine to the VAS Experts Solution

On 10 September 2025, VAS Experts hosted a live webinar on migrating from Sandvine to the Stingray Service Gateway (SSG). A leading Middle Eastern telco shared their real migration experience, including enhanced traffic control, QoS, regulatory compliance, and advanced analytics.

DPI in Action - Inside Stingray Service Gateway

Discover how Deep Packet Inspection (DPI) works inside the Stingray Service Gateway by VAS Experts. Our high-performance DPI engine processes traffic at up to 240 Gbps per server, scaling to 4.6 Tbps in clusters, and recognizes over 6,000 applications and services — from messengers to VPNs.

Unified Software Solution for Telecom Operators

We’ve brought together DPI, BNG, and CG-NAT into a single powerful software platform - the Stingray Service Gateway. Designed for telecom operators worldwide, it makes networks faster, more secure, and more profitable, combining performance, flexibility, and intelligent traffic control in one solution.

The ALL-IN-ONE approach by VAS Experts and ITPOD

In this video, we show how software from VAS Experts and hardware solutions from ITPOD help operators solve key tasks.

L3-Connected CG-NAT and NAT Flow export

In this video we provide a detailed explanation of how Connected-L3 NAT functions and demonstrate the configuration process via CLI and GUI. The video also covers the export of NAT Flow statistics.

QoE: Uplink monitoring service

Discover how to monitor uplinks and ensure seamless internet access for your users. This video introduces a service that helps identify connection issues between providers and online resources, offering step-by-step guidance on setup, configuring monitoring widgets, and tuning the service sensitivity. Learn how to resolve uplink problems, all while maintaining top-tier service for your subscribers.

QoE: Troubleshooting of user’s Internet access degradation

In this video, discover a powerful solution designed to boost customer loyalty for telecom operators by identifying subscribers facing technical issues and taking proactive measures to retain them. We introduce our Quality of Experience (QoE) module, which allows early detection of client-side problems. Learn how the QoE server processes IPFIX (NetFlow v10) statistics collected by DPI. These statistics, including RTT and retransmits, are crucial for diagnosing and resolving issues. We’ll demonstrate the QoE interface and the aggregation process that simplifies data analysis by compressing and organizing session records. We’ll also guide you through setting filters to identify subscribers with technical issues and how telecom operators can take preventive actions to offer timely technical support.

Allow lists and Captive Portal (Services 5 and 16)

In this video, we demonstrate the setup of services 5 and 16 using GUI and CLI, and how to attach them to different devices. We cover two methods for blocking UDP traffic and show how to verify the blocking results using QoE analytics.

Subscriber policing with scheduled tariff plans

In this video, we provide a step-by-step tutorial on configuring protocol and ASN prioritization. We then demonstrate how to create a scheduled tariff plan based on this prioritization, apply it to a subscriber, and showcase its functionality using Speedtest.com.

Guidelines for Protocol Prioritization for the Virtual Сhannel Policing Level

In this video, we provide detailed instructions on setting up policing at the vChannel level. Using CIDRs, we split the traffic into two virtual channels and apply two tariff plans of 10 Mbps and 2 Mbps to them. Next, using Speedtest, we demonstrate the operation of virtual channel policing on two test devices.

Guidelines for Protocol Prioritization for the Common Сhannel Policing Level

In this video, we provide a step-by-step guide on protocol prioritization for the common channel policing level using Stingray Service Gateway, showing an example of prioritizing YouTube traffic over torrent traffic with limited channel bandwidth.
