is running.
In case of MOS test VoFi
traffic is transmitted as long
as requested in the test
parameters, constant traffic
at the rate of 100 kBs/s.

MOS test most probably
contain significant amount of
data.
For example, the FTP download test transfers by default 2 megabytes of data that does not
take long. The amount of data is exceptionally high for data transfer in a logistics environment
but on the other hand in office environment transfer of this size is relatively low. The test
parameter should be adjusted, either to simulate typical transfer or to save the bandwidth
while keeping the transfer size high enough to give measurements out of the network.

The binary

volume-

The chosen test profile and
individual test parameters
dictate whether the Eye
keeps testing a long time or
is there frequent test
management traffic.
Duration of one test varies
from a few seconds to almost
minutes per request
depending on the test type.
