网络测试之iperf3
概述
简介
iperf3
The iperf series of tools perform active measurements to determine the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, protocols, and buffers. For each test it reports the measured throughput, loss, and other parameters.

This version, sometimes referred to as iperf3, is a redesign of an original version developed at NLANR / DAST. iperf3 is a new implementation from scratch, with the goal of a smaller, simpler code base, and a library version of the functionality that can be used in other programs. iperf3 also incorporates a number of features found in other tools such as nuttcp and netperf, but were missing from the original iperf. These include, for example, a zero-copy mode and optional JSON output. Note that iperf3 is not backwards compatible with the original iperf.

iPerf 系列工具通过主动测量来确定 IP 网络上可实现的最大带宽。它支持调整与时间、协议和缓冲区相关的各种参数。每次测试都会报告测得的吞吐量、丢包率及其他相关参数。
