Datasheet

Overview

The VIAVI TeraVM Core Test is a test solution for full wraparound testing of 5G Standalone (SA) and Non-Standalone (NSA) core networks as well as legacy 4G/3G/2G cores. It gives core network engineers a controlled and repeatable test environment for developing products against evolving 3GPP specifications and simplifies the development and validation lifecycle of the core network.

The platform emulates tens of thousands of base stations, millions of UEs and their user applications to create a realistic RAN environment for stressing the core. Support for 3GPP interfaces such as N1, N2, N3 and N6, as well as 4G/3G/2G interfaces, allows UE application and mobility behavior to be emulated for inter-5G and inter-RAT scenarios.

Wraparound testing

TeraVM Core Test can test the entire core or wrap around individual Service Based Architecture (SBA) components such as the AMF, SMF and UPF. VIAVI-emulated SBA nodes can be plugged into the test environment when certain components are missing from the customer's core. It can be used together with the TeraVM Core Emulator for RAN-to-core testing.

Deployment and automation

The software runs in a lightweight virtual machine on standard x86 hardware, is Kubernetes and container-ready, and is supported on GCP, Azure and AWS. A 1U server-based configuration is available for lab and field use. Licenses can be shared across lab locations and time zones, and CI/CD integration is provided through VAMOS and open-source tools such as Jenkins.

Extended test scope

Additional capabilities cover Non-3GPP access testing (N3IWF and ePDG) over untrusted networks such as Wi-Fi, voice testing across 4G and 5G, negative testing through error injection on the N1/N2 interfaces, and 5G core firewall testing with stateful traffic mixed with threat and malware traffic.
