If you've worked on networks long enough, you're probably familiar with
iperf. This application is great for testing
throughput between two computers on your network. Unfortunately, if you find
yourself in a situation where you have less than two computers to test with,
iperf is less than ideal.
Fortunately, Cisco includes TTCP on most of
its platforms. TTCP is a networking tool for measuring throughput between 2
systems. It is very similar to
iperf, and most users accustomed to the
iperf should find TTCP very easy to work with.
Be aware that the
ttcp command is hidden in Cisco IOS and will not be found in
the normal command lists. Like,
iperf, you will need to set up both a client and
server. Either side can be a PC or a Cisco device. For more information, see
Using Test TCP (TTCP) to Test Throughput.
