It can test either TCP or UDP throughput. To perform an iperf test the user must establish both a server (to discard traffic) and a client (to generate traffic). Iperf simply tests throughput by sending a stream TCP/UDP packets of a set size, over a set time, and then calculating the throughput.

What is iPerf / iPerf3 ? iPerf3 is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, buffers and protocols (TCP, UDP, SCTP with IPv4 and IPv6). For each test it reports the bandwidth, loss, and other parameters.

ID [4] bandwidth was 57.9 GBits/sec – This is the connection from the server to the client. ID [5] bandwidth was 57.8 GBits/sec – This is the connection from the client to the server . UDP Jitter test. Restart your iperf server with the -u option to let it accept UDP packets. iperf -s -u. You should see output similar to the following:

Iperf is a tool to measure the bandwidth and the quality of a network link. Jperf can be associated with Iperf to provide a graphical frontend written in Java. The network link is delimited by two hosts running Iperf. The quality of a link can be tested as follows: - Latency (response time or RTT): can be measured with the Ping command. - Jitter (latency variation): can be measured with an How to use iperf, a complete tutorial - ICTShore.com
