Claim Text:
1. A method, comprising: installing, at an access point that (1) includes a first software image and (2) is operatively coupled to a network controller via a network, a second software image different from the first software image; defining, in response to the installing and at the access point, a virtual client configured to send, at a first time and to the network controller via the network, a first validation data unit that causes the network controller to send a second validation data unit to the access point; sending, to the network controller, a signal indicative of a successful receipt of the second validation data unit if the virtual client receives the second validation data unit at a second time after the first time, the signal indicative of the successful receipt of the second validation data unit being indicative of a time value associated with an elapsed time between the first time and the second time; and sending, to the network controller, a signal indicative of a failure of a receipt of the second validation data unit if the virtual client does not receive the second validation unit from the network controller.
