Networking Tools - Part #2 (iperf3)
Welcome to the second video in my Networking Tools series!
In this chapter, we dive deep into iperf3, an essential tool for testing TCP and UDP network performance. If you're looking to understand how to measure bandwidth, throughput, latency, and more, this video will cover it all.
We'll explore:
How to perform basic iperf3 tests (upload, download, and two-directional traffic)
Asymmetrical vs. symmetrical links and full/half-duplex modes
The impact of test duration and reporting intervals
Factors that influence TCP performance like latency, packet loss, and window/buffer size
Running tests with parallel TCP connections to stress test your network
Measuring UDP performance and how it differs from TCP
Visualizing performance results using Grafana
Stay tuned for a detailed look at advanced tools like nuttcp, qperf, and netperf in the next chapter!
