QURS032
Retransmissions in FTP test
Measures the round trip time between an
Eye and a Sonar server. The test pings a
server N times with zero wait time between
the pings. The default ping packet size is 32
kilobytes. The default ping count N is 10.

QURT004
32B active RTT
Measures the round trip time between Eye
and Sonar server. The test uses a serie of
pings to ping server 20 times with zero wait
time between the pings. The calculation is
done internally in Eye and the output of the
test is average, 95% percentile, max and
min values of RTT. The objective is to
measure the ping quality, not ping
availability.

QURT007
Ping success rate
Number of successful pings divided by the
total amount of ping attempts.

TR001
AP uplink throughput
Measures the amount of uplink data
transmitted to an AP during a
measurement period. During the test, an
Eye listens traffic for 15 sec per each
managed access point.
