Introduction to
Performance Testing
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.
When using a Peer endpoint, separate upstream
and downstream measurements can be shown
for Throughput, Loss, Latency, and Jitter.
When using a Reflector, the EtherScope reports
round-trip data for all measurements. Separate
upstream and downstream traffic meas-
urements are not possible.
The EtherScope nXG Controlled Edition can act
as the controlling Source for the performance
test or as a Peer for a test conducted by
different source device, such as another
EtherScope nXG Controlled Edition or a
OneTouch AT 10G.
Other NetAlly testers work with the EtherScope
to perform network performance testing:
