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 an 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
bandwith while keeping the transfer size high enough to give measurements out of the
network.

Spectrum Analysis and MOS
test most probably contain
significant amount of data.
The data transferred in only test parameters and in most cases results of analysis, sometimes
raw measurements.
Naturally the number of Eyes is directionally proportional the traffic load as each Eye
connection are independent and concurrent. One single Eye typically executes a test in one
minute in the average. However, there are tests that finish in 10 seconds (practical minimum)
and few tests run few minutes.
The communication protocol is both minimal and binary so the traffic from Carat to Eye is very
economic. The measurement result minimum is around 100 bytes in one message and the top
range is the spectrum measurement (not available in all configurations) that returns
approximately 300 times a 50 byte result unit.
In data communications sense the traffic for single Eye is minimal.
