Using iperf to measure the bandwidth and quality of network

According to iperf project site. This writeup is taken from iPerf Tutorial by OpenManiak. For a more detailed and in-depth writeup, do read up on the iPerf Tutorial

Iperf was developed by NLANR/DAST as a modern alternative for measuring maximum TCP and UDP bandwidth performance. Iperf allows the tuning of various parameters and UDP characteristics. Iperf reports bandwidth, delay jitter, datagram loss.

Iperf can generate traffic using TCP and UDP Traaffic to perform the following kinds of test

• Latency (response time or RTT): can be measured with the Ping utility.
• Jitter: can be measured with an Iperf UDP test.
• Datagram loss: can again, be measured with an Iperf UDP test.
• Bandwidth tests are done using the Iperf TCP tests
