Iperf output after adding "-T" and "-I" parameters

Ipef3-c ip-t 20-i 5

After specifying the "-n" parameter, the "-T" parameter fails, and Iperf automatically ends after the packet of the specified size has been transferred.

Ipef3-c ip-i 10-n XX

The Iperf client allows data to be sent from a specific file, which can be implemented with the "-F" parameter

Ipef3-c ip-f xx-i 5-t 20

To unify the rate units, the "-F" parameter is used here to display the output through MBytes

Iperf3-c ip-n xx-i 5-f M

2 multi-Threading enabled with "-P" parameter

Test UDP packet drops and delays

Iperf3-c Ip-u-B 100m-f m-i 3

In Figure 7, focusing on a piece of content under the dashed line, in which the "jitter" column represents the jitter time, or the transmission delay, the "lost/total" column represents the missing datagram and the total number of datagrams, followed by 0.33% is the average drop rate, "datagrams" Column shows the total number of transmitted datagrams

This output is too simple, to learn more detailed UDP packet loss and delay information can be viewed on the Iperf server, because the client performs the transmission test while the server also displays the transmission status, 8 shows

Iperf3-s-I. 3

Figure 8 UDP transport status shown on Iperf server

In this output, the transmission delay and packet loss rate are recorded in detail in the transmission process, and the packet loss rate and delay increase with the increase of the transmission data in the UDP application. Delays and drops can be mitigated or repaired by altering the application, such as video streaming applications, which can tolerate a greater delay by caching the data.

Bandwidth Mbits/sec said is the Hundred Gigabit Network/8 Mbytes/sec

Transfer MBytes transfer how many m

Zabbix display is what is commonly referred to as the Gigabit network, is the transmission of the results of mbits/sec
