| message size | 64 | 512 | 1k | 4k | 8k | 16k |
| Anticipated bandwidth | ||||||
| Actual bandwidth |

A Matplotlib library is used for drawing a coordinate system graph according to the data, and actual values and expected values are drawn in different linearity in the same graph. The actual value and the expected value result are clear at a glance.
The application has the beneficial effects that: the shell-based method for testing the IPerf performance enriches the method for testing the IPerf, can adjust the testing parameters according to different requirements to meet different testing scene requirements, and is displayed in the same two-dimensional graph with expected values, so that the result is clear at a glance.
The indexes to be measured in the application include data packet throughput, packet loss rate and delay, and although the indexes are used for UDP data packet throughput, packet loss rate and delay, the UDP protocol is a non-connection-oriented lightweight transmission protocol and does not provide reliable data transmission service, so that the attention to UDP application is not how fast data is transmitted, but the packet loss rate and delay index. TCP is a connection-oriented, reliable, byte-stream-based transport layer traffic protocol, so TCP is used to test bandwidth, UDP to test packet loss and delay metrics.
The test network bandwidth is passed through tcp mode, the packet loss rate and delay are passed through UDP mode, and the types described herein are classified into UDP and tcp. In the tcp type, it is necessary to specify the size of a message packet of inputs 64b,512b,1k,4k,8k, etc., and input a network bandwidth expected value in this case. In the udp mode, the expected packet loss rate and delay value need to be input under the specified network bandwidth under the condition of the sizes of message packets such as instruction inputs 64b,512b,1k,4k,8k and the like. And store each parameter correspondence for subsequent generation of a corresponding iperf instruction.
The application aims to solve the technical problem of providing the method for testing the iporf, which can cover various scenes and graphically and intuitively display the test result and the expected value of each scene. The automatic coverage of various scenes is realized, the manual participation is reduced, the labor is saved, the analysis efficiency of the test result file is improved, and the whole test efficiency is improved.
