Aviz Networks details service node capabilities validated with Spirent Landslide

Aviz Service Nodes (ASN) provide enhanced network observability by extracting and correlating metadata from 4G-LTE, 5G Non-Standalone (NSA), and 5G Standalone (SA) network interfaces, delivering subscriber intelligence that informs network analytics and operations. This capability is pertinent for enterprise IT and security leaders seeking to optimize performance, security, and Quality of Service (QoS) in evolving telecom infrastructures.

Research overview

Autonomous System Number (ASN) operates on general-purpose hardware and delivers metadata extraction and correlation across key telecom interfaces. It processes both control and user plane data to link subscriber activity comprehensively, supporting network monitoring and analytics for 4G-LTE and 5G architectures. These operations enable deeper insight into subscriber behavior and network conditions essential for telecom management.

Technical breakdown

The ASN platform effectively extracts and validates metadata by interfacing with various segments of 5G SA, 5G NSA, and 4G Long Term Evolution (LTE) systems. It identifies and verifies data accuracy to ensure reliable network intelligence. Additionally, ASN incorporates Deep Packet Inspection (DPI) techniques, utilizing parameters such as Server Name Indication (SNI), IP addresses, ports, and application behavior for classifying telecom traffic and identifying applications.

ASN's architecture supports handling complex mobility events such as handovers by monitoring control and user plane packets during transitions between base stations, maintaining seamless subscriber tracking. The platform is designed to handle handovers across diverse 5G deployment scenarios, ensuring consistent metadata correlation throughout network changes.

Performance and scalability

The system demonstrated capacity to manage metadata extraction and correlation for up to three million subscribers across 5G and 5G-NSA networks. It supports user plane traffic throughput of 150 Gbps, validated under mixed packet size conditions to emulate real-world telecom environments. Performance testing utilized Spirent Landslide to simulate extensive 5G network traffic, confirming ASN's capability to sustain processing demands of large-scale deployments.

ASN’s deployment flexibility allows operation on both traditional telecom hardware and cloud-native cores. Its x86-based, lightweight design facilitates edge deployment, enabling localized correlation and real-time analytics to reduce latency and improve network responsiveness.

Operational impact

ASN’s metadata extraction and application identification enhance network observability, supporting traffic management, QoS enforcement, security monitoring, billing accuracy, and analytic functions. The platform’s handover management capabilities maintain continuous visibility of subscriber sessions during mobility, critical for maintaining service continuity and accurate network insights.

By enabling vendor-agnostic interoperability and supporting diverse network environments, ASN assists operators in upgrading 5G infrastructures while preserving consistent monitoring and intelligence functionalities.
