Abstract: A method for generating a simulated network using a graphical user interface (GUI). A network topology generated at a GUI by a user is received, wherein the network topology includes a plurality of devices and at least one connection between devices. A build file describing the network based on the network topology is automatically generated. A user is able to create and edit a simulated network through the GUI, thereby obviating the need for manually coding a simulated network. Large simulated networks can be quickly created, edited and maintained.

Abstract: A distributed computer network testing system includes a test controller and at least one test agent. One or more test agents are configured with interpreters configured to execute instructions contained in a test script. When the test begins, the test controller publishes the test script to an event engine that broadcasts the script on the network. Test agents subscribing to the test script receive the script. Script receipt is the event that triggers test script execution by each interpreter on each subscribing test agent. Each test agent sends test results to the test controller that, in turn, sends all results to a test analysis agent. The analysis agent analyzes the test results and produces a test report that is output to the user.
