iPerf is a command-line tool to measure the bandwidth and quality of a network link. It requires two hosts with the tool installed in order to execute the test with one functioning as a ‘server’ and the other as the ‘client’. iPerf can be used to test:
- Jitter ( measured via UDP)
- Datagram loss (measured via UDP)
- Bandwidth (measured via TCP)
You can combine this information with the average, min, and max latency results from a prolonged ping output in order to get a better idea about the quality of your link.
