9.10 Packet Generator and Monitor
The Ethernet interface board has a built-in UDP packet generator compatible with
the bandwidth measurement tool iPerf.
iPerf is freeware, (available from
http://dast.nlanr.net/Projects/Iperf/) in UDP mode.
In addition, it has packet monitor to perform Ethernet frame or IP packet sniffing or
to terminate a selected traffic stream generated by either the UDP packet
generator or iPerf and provide statistics for that stream.
Typical use cases for the traffic generator/monitor are:
• Generate traffic on a modulator/modem and monitor this traffic on a
demodulator/modem;
• Generate traffic from an iPerf client on a PC, and monitor this traffic on a
modulator, modem or demodulator/modem (via modulator);
• Generate traffic on a modulator/modem and monitor this traffic on an iPerf
server on a PC (via demodulator).
