Emulab FAQ: Using the Testbed: What is LinkTest
LinkTest is a recent feature in Emulab that allows you to automatically test the traffic shaping on your links and lans. You can access LinkTest from the web interface or from the command line on users.emulab.net. More information about LinkTest can be found on the LinkTest tutorial page.
We strongly recommend that you always use LinkTest or some other testing mechanism to ensure that your links and lans are behaving as you expect them to!
