Wired Performance Test
Purpose
The OneTouch AT analyzer's Wired Performance Test provides
point-to-point performance testing of a traffic stream across
wired IPv4 network infrastructure. This test is typically used to
validate network performance. It quantifies network
performance in terms of throughput, loss, latency, and jitter.
The OneTouch AT analyzer exchanges a stream of traffic with
Peers or Reflectors and measures the performance of the traffic
stream. You can run the test at a full line rate of up to 1 Gbps for
performance validation, or at lower speeds to minimize
disruption when troubleshooting operational networks.
The test is based on the Internet Engineering Task Force (IETF)
RFC 2544 Benchmarking Methodology for Network Interconnect
Devices.
You can use the Wired Performance Test to

verify that a network configuration delivers the expected
performance

evaluate newly deployed equipment

evaluate network performance prior to deployment of new
services such as VoIP
Connecting the Source and the Endpoint
1
Connect the controlling OneTouch AT analyzer to a point in
the network (the source).
2
Connect a peer or reflector to another point in the network
(the endpoint). Network performance is measured between
the two points.
