Aviz Networks outlines Spirent Landslide validation for ASN capabilities

Aviz Networks’ Service Nodes (ASN) were validated for metadata extraction, user/control-plane correlation, and handover support across 4G-LTE, 5G-NSA, and 5G-SA using Spirent Landslide traffic emulation, with reported scalability to 3 million subscribers and 150 Gbps user-plane throughput.

Research Overview

The vendor describes ASN as a network observability component that operates on general-purpose x86-style hardware and focuses on subscriber intelligence through metadata extraction and correlation across telecom interfaces.

To confirm ASN accuracy and performance against its stated KPIs, the team used Spirent Landslide to emulate 5G and 5G-NSA components under configurations including standalone and non-standalone scenarios.

Key Findings

ASN validation covered metadata extraction across 5G-SA, 5G-NSA, and 4G-LTE interfaces, with an emphasis on extracting, retrieving, and verifying metadata to support consistency and correlation between user and control-plane data.

The reported results also include handover handling for 5G and 5G-NSA cases, application identification using deep packet inspection signals, and performance/scalability validation under mixed traffic packet sizes.

Technical Breakdown

For metadata extraction and validation, ASN is described as working across multiple 5G and 4G interfaces to correlate user and control-plane packets by identifying, retrieving, and verifying relevant metadata from telecom network interfaces.

For handovers, ASN is described as managing the extraction and correlation of control and user packets during mobility events where an active call or data session shifts between base stations.

Operational Impact

For application identification, ASN is described as using deep packet inspection to identify applications based on signals that include Server Name Indication (SNI), destination IP address, destination port, and observed application behavior.

For performance and scalability, ASN is described as supporting up to 3 million subscribers in 5G and 5G-NSA networks while correlating control packets for user-plane traffic up to 150 Gbps, with validation using mixed packet sizes resembling real-world scenarios.

Blog Signals brief is a fact-based summary of the vendor blog, focused on how ASN capabilities for metadata correlation, handover handling, application identification, and reported scaling were validated with Spirent Landslide traffic emulation for 4G-LTE, 5G-NSA, and 5G-SA use cases.
