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.

• EtherScope nXG
• LinkRunner 10G
• CyberScope
• OneTouch 10G (The G2 unit cannot be used as a peer or reflector)
• OptiView XG

Reflector (1G Line Rate Performance Testing)

Reflection will give you total round trip for loss, latency, and jitter.

• LinkRunner AT
• LinkRunner G2
• Software Reflector (Results may vary depending on the Network Card, Driver, and other PC specifications)
  • Tested to work only on Windows 10.
  • Download the free NPT Reflector software from https://link-live.com/downloads. You will find the latest version under the EtherScope nXG heading.
