Network Measurement Tools
The easiest way to install the most up-to-date version of several useful network test tools is from the perfsonar.net software repo.
For Linux-based systems, follow the instructions for installing the perfsonar-tools bundle.
For OSX systems (install homebrew)
brew install iperf iperf3 nuttcp owamp
Note: Be sure to tune your hosts TCP settings, as described here.
|pScheduler||schedules tests, one at a time (wrapper for iperf and nuttcp)|
|iperf /iperf3||measures end-to-end TCP/UDP performance|
|nuttcp||measures end-to-end TCP/UDP performance|
|owamp||measures latency, loss, and jitter|
|traceroute / scamper||measures the network path and MTU|

|tcpdump||dumps all TCP header information for a specified source/destination|
|tcptrace||formats tcpdump output for analysis using xplot|
