Outline of iperf programOutline of iperf program

TCP throughput or link bandwidth (using UDP) measurement program

“iperf –help” command shows the usage of the program

TCP clientC:>iperf –c 143.248.134.26 –p 9901 –

n 1000Mb –i 1

TCP serverC:>iperf –s –p 9901

Ex) TCP connection between server and client
