Since UDP is stateless, it has no idea how far it can push the network like TCP does. So iperf has some sane defaults for sending UDP traffic, and by default targets 1Mbps of throughput. The previous examples are worked around this, by specifying our target bandwidth of 100M using the ...
在iPerf中,当执行UDP测试时,抖动是一个重要的指标之一,它能帮助评估网络连接的质量。UDP测试通常会更加关注抖动,因为UDP协议本身不提供丢失数据包的重新传输机制,而且应用程序可能对数据到达的时间敏感。 通过测量抖动,您可以了解到数据包到达目的地的时间变化范围。较低的抖动表示网络连接的稳定性较高,而较高的抖动可...
We know this from the previous server command. The -u means to send a UDP data traffic. The “-t 20” means to send a traffic for 20second. The “-i 1” means showing the iperf output interval for each second. The “-b 200M” means that the UDP data pumping rate is 200Mbps. ...
在lwip官网下载的文件中lwip-2.1.2\src\apps\lwiperf中存放了iperf的测试文件,但是当前文件只实现了TCP的速率测试,本文使用的是先楫HPM6750EVK开发板提供的SDK中提供的lwiperf.c文件,该文件在官方的lwiperf.c文件上实现了对于UDP性能的测试,其测试例程也是参考了先楫HPM6750EVK开发板的测试例程。

The --pacing option was added in iPerf 3.2 to allow the rate check frequency to be configurable. Prior to this, the default check time was 100ms, causing bursty UDP traffic and a source of much confusion. You canread about this bug and the addition of the pacing flag here. ...

Sanity checks for UDP send sizes have been added (#390), and existing checks on the --window option have been improved (#557). The TCP rttvar value is now available in the JSON output (#534), as are the socket buffer sizes (#558). ...
