前言

这里列出一部分网络质量的检查手段

PING 时延检查

我们可以通过PING命令来检查节点之间的延迟，如

--- www.a.shifen.com ping statistics ---
30 packets transmitted, 30 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 8.577/10.886/23.326/3.899 ms

主要关注丢包率和时延。

30 packets transmitted, 30 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 8.577/10.886/23.326/3.899 ms

可以看到上述的平均时延 10.886ms

吞吐量测试

在需要测试的服务端执行

1
iperf3 -s

客户端执行

1
iperf3 -c 172.20.0.131

然后记录接收端的数据。

PPS性能测试

PPS=发送成功的报文数÷测试时间。

服务端执行

1
iperf3 -s

客户端执行

1
iperf3 -u -l 16 -b 100m -c <ip>
