Network Quality Measurement
See Directional Quality and Load Effects
From routine quality checks to performance assessment under load.
Bidirectional Link Quality Packet Loss Rate · RTT
Load Testing
See how delay and loss change as the load increases.
TCP Throughput Testing
Measure upload and download goodput and application-layer RTT separately.
Built-in local performance self-tests help identify test-host bottlenecks.

Export impairment scenarios
and bring them into the lab
Export measurements as impairment scenarios. Use a NetAccura WAN emulator to reproduce link conditions for troubleshooting and version regression testing.
