Network performance is measured between a Source device, on which the test is configured and controlled, and up to four Endpoint devices that exchange traffic with the source. There are two endpoint types: Peers and Reflectors. For an overview on performance testing please see our Tech Tips: https://www.netally.com/network-performance/performance_test_endpoints/
Peer: When using a Peer endpoint, separate upstream and downstream measurements can be shown for Throughput, Loss, Latency, and Jitter.
Reflector: When using a Reflector, the EtherScope reports round-trip data for all measurements. Separate upstream and downstream traffic measurements are not possible.
The EtherScope nXG and LinkRunner 10G (Must be on software version: 1.6.0.13) or CyberScope can act as the controlling Source for the performance test or as a Peer for a test conducted by different source device/endpoint. Below is a list of endpoints that can be used with the NetAlly Performance Test and their capabilities:
Peer (10G Line Rate Performance Testing)
A peer will give you separate downstream and upstream values for loss, latency, and jitter.
Reflector (1G Line Rate Performance Testing)
Reflection will give you total round trip for loss, latency, and jitter.
