Monitoring and Assuring 5G Network Performance with Active Multi-Domain Testing

5G service assurance requires continuous, active testing across every network domain — radio access, backhaul, aggregation, core, and data center. Passive monitoring of user traffic and signaling cannot detect degradation before subscribers are affected, nor can it validate performance before new services launch. Active test agents — deployed as virtual network functions (VNFs) or physical TestHead probes — generate realistic synthetic traffic that exercises each domain under controlled conditions. Correlation engines aggregate results across domains to isolate root causes.

A comprehensive methodology addresses three operational modes: pre-launch validation, where agents emulate subscriber traffic to confirm service-level agreement (SLA) compliance before deployment; continuous monitoring, where agents run scheduled and on-demand tests against live segments; and troubleshooting, where targeted test flows pinpoint degradation to a specific domain, link, or network function.

Active Assurance Solution

End-to-end 5G service assurance requires active test agents that operate across all network domains. The Keysight active service assurance solution deploys virtual and physical agents to generate synthetic traffic, measure SLA metrics, and pinpoint performance degradation across radio, backhaul, core, and cloud infrastructure.
