Solutions for data centers and Autonomous System Numbers (ASN) from VAS experts
Protecting against cyberattacks and maintaining a stable network infrastructure are critical for data centers. Data centers face many threats, including DDoS attacks such as TCP SYN floods that can overload servers and disrupt services. In this article, we will examine how VAS Experts' Stingray Service Gateway (SSG) effectively handles such attacks based on real-world examples of its use.
SSG as VNF for Telco Cloud
Telecom operators are moving from physical networks to cloud-based solutions to increase flexibility, resiliency and lower operating costs. This approach is fundamentally different from the traditional model based on specialized hardware. Operators now need to develop and manage services in data centers that integrate both physical and virtual ecosystems, while ensuring interoperability with competitive vendors.
SSG as a Border Router. ARP management.
By default, the SSG functions as an L2 Bridge, but since 2017 it has been developed as a full-fledged BRAS/BNG. Routing functionality is particularly important for a service gateway, as it is required to communicate with external networks, provide access to internal resources and improve resilience. The VAS Experts team provided the opportunity to embed proven solutions in the role of Soft-Router such as BIRD, FRRouting and QUAGGA into SSG.
Digest April-June 2024
Dear colleagues and partners! We are pleased to present you our first quarterly digest, in which we review the key events and updates of the company over the last 3 months.
What is IDS - Intrusion Detection System
An intrusion detection system is a network security tool that monitors network traffic and devices for malicious or suspicious activity, or security policy violations.
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.
Effective network monitoring with SSG and QoE module + practical case study
Network monitoring is the process of continuously observing network health and operation to identify and correct potential problem areas. Standard monitoring tools typically provide general information about network traffic and load. However, additional tools are required for detailed analysis and optimization of network performance.
When the mobile network is unavailable: why start calls over the Internet
VoWiFi technology allows making calls by phone number outside the coverage area of the mobile network using Wi-Fi. Today, we decided to discuss the relevance of such service and key ways to set it up: from OTT and UMA to untrusted access to EPDG. We will also look at the prospects of the technology and the challenges faced by telecom operators offering the service of calls over the Internet.
100G card support for SSG 200
In this article we will consider an example of a real load on a 64-core processor for SSG 200 in BRAS/NAT/DPI mode.
On-stick — a new mode of the Stingray Service Gateway to save router ports
When physical ports on network equipment become insufficient, the service provider has to expand the network core. VAS Experts offer a solution to this problem without additional costs. To achieve this, you need to use the new On-Stick mode, which was added to the Stingray Service Gateway in 2023.
