Verifying SLA Compliance Across Multi-Domain Ethernet and IP Networks

Ethernet and IP service assurance requires real-time, end-to-end performance validation across multi-domain networks — including access, backhaul, aggregation, core, and data center segments. Traditional passive monitoring collects data from network functions once services are running, but it cannot test performance at turn-up, during low-traffic periods, or across third-party network segments where you lack direct visibility. Active assurance addresses these gaps by deploying virtual test agents (VTAs) at strategic points throughout the network. These agents inject synthetic traffic that emulates real user sessions across Ethernet and IP protocol layers, then measure throughput, latency, jitter, packet loss, and perceptual quality metrics such as Mean Opinion Score (MOS) on each segment independently.

This segment-by-segment approach allows engineers to isolate degraded links or functions — whether in owned infrastructure, third-party interconnects, or virtualized network elements — before customers experience disruption. Combined with passive telemetry and performance counter data, the active-plus-passive methodology provides comprehensive automation of service turn-up, continuous monitoring, and troubleshooting workflows.

Ethernet and IP Service Assurance Solution

End-to-end Ethernet and IP service assurance requires active testing with distributed test agents across every network segment. The Keysight ethernet assurance and lab test automation solution combines virtual test agents, proactive analytics, and automated troubleshooting to verify SLA compliance, accelerate service activation, and isolate performance issues across access, backhaul, core, and data center domains.
