Network Performance Testing

Test Description​

Using the iperf3 tool for testing (the SDK source code package is equipped with this tool). iperf3 is a tool for measuring network bandwidth for TCP, UDP, and SCTP. It is used to measure the maximum bandwidth that can be achieved on an IP network.

Test Method​

First, make sure that the development board and the PC can ping each other before proceeding to the next test.

PC Side​

The PC side acts as the server, and execute iperf3 -s -f m.

Development Board Side​

The development board acts as the client, and execute iperf3 -c 192.168.1.1 -f m -i 1 -t 60 to perform the network testing.

Common Parameters for iperf3​

For the server, the common configuration parameters for iperf3 are as follows:

-s       indicates the server side;
-p port  defines the port number;
-i sec   sets the time interval between each report in seconds. If set to a non-zero value, the test report will be output according to this time interval. The default value is zero.

For the client, the common configuration parameters for iperf3 are as follows:

-c ip   indicates the IP address of the server;
-p port indicates the port number of the server;
-t sec  specifies the duration of the transmission test. Iperf will repeatedly send data packets of the specified length within the specified time. The default is 10 seconds.
-i sec  sets the time interval between each report in seconds. If set to a non-zero value, the test report will be output according to this time interval. The default value is zero;
-w size sets the socket buffer to the specified size. For TCP, this setting is the TCP window size. For UDP, this setting is the buffer size for receiving UDP packets, limiting the maximum value of the packets that can be received.
--logfile    saves the output test results to a file.
-J  outputs test results in JSON format.
-R  performs reverse transmission. By default, iperf3 uses upload mode: the client sends data, and the server receives it; if you need to test download speed, use the -R parameter on the client side.
