Patent ID: 8661116

Claim:
A method, comprising: receiving, at a first interface of a first network device of a first system under test, a test initiation message sent from a control device, wherein the first interface of the first network device is selected to receive the test initiation message and not a second interface, of the first network device, of another system concurrently under test based on a determination that: different queues or different buffers are associated with each of the first interface and the second interface, and results obtained from the first system under test concurrently with the other system under test do not vary from results in which the first system under test and the other system under test are in sequence; generating, by the first network device, first test data including at least source information associated with the first network device, destination information associated with the second network device, and timestamp information associated with the first test data; transmitting, by the first network device, the first test data to the second network device via a data network of the first system under test; receiving, at the first network device, second test data from the second network device, wherein the second test data includes first testing results calculated by the second network device based on the first test data; calculating, by the first network device, second testing results based on the second test data; generating, by the first network device, collective performance information based on the first testing results and the second testing results; storing, at the first network device, the collective performance information; and periodically transmitting, from the first network device, the stored collective performance information, via a second data network that is not included in the first system under test, to a storage device that is not included in the first system under test.
