I am trying to make sense of the raw logs of an iperf3 UDP bidIrectional test.
Here are the iperf3 client logs:
[ ID][Role] Interval Transfer Bitrate Jitter Lost/Total Datagrams

iperf Done.
In the per second datapoints, for example,
[ 5][TX-C] 0.00-1.00 sec 1.04 GBytes 8.93 Gbits/sec 124718
[ 7][RX-C] 0.00-1.00 sec 586 MBytes 4.92 Gbits/sec 0.017 ms 51093/119778 (43%)
Is TX-C referring to bandwidth for data sent by the client?
Similarly, in the server logs, as shown below,
[ 5][RX-S] 0.00-1.00 sec 586 MBytes 4.92 Gbits/sec 0.019 ms 53669/122373 (44%)
[ 6][TX-S] 0.00-1.00 sec 1.02 GBytes 8.72 Gbits/sec 121799
is TX-S and RX-S referring to server receive and send bandwidth?
