Summary:A controller may control switches such as physical and software switches in a network. The controller may generate virtual switches from groups of end hosts in forming a virtual network topology. The controller may receive one or more network policy rules that govern network traffic through the switches. For a given network policy rule, the controller may perform a test in determining whether the network satisfies the network policy rule. The test may be performed based on a testing rule identifying test parameters and expected test results. The controller may perform tests in determining whether the network satisfies the testing rule and the corresponding network policy rule. The tests may be performed via simulation at the controller or by injecting a tagged test packet into the network.
