Abstract:
1. A method performed by one or more network devices, the method comprising: providing a test environment comprising a subnetwork and a main network; continuously transmitting a test signal from a first location within the provided test environment, the test signal being received, after a time delay, at a second location within the test environment; introducing a plurality of fault conditions into the test environment, the plurality of fault conditions occurring sequentially, one at a time, where each of the plurality of fault conditions, is corrected before a subsequent fault condition, of the plurality of fault conditions, is introduced into the test environment, where a test signal is transmitted at least once during each of the plurality of fault conditions; monitoring first changes on the time delay associated with, respectively, introducing each of the plurality of fault conditions into the test environment; monitoring second changes on the time delay associated with, respectively, correcting each of the plurality of fault conditions before introducing the subsequent fault condition, of the plurality of fault conditions; and storing the first changes and the second changes.
