Iperf is a tool to measure IP bandwidth using UDP or TCP. It allows
for tuning various parameters, and reports bandwidth, delay jitter,
and packet loss. It supports IPv6 and multicast. 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.
