Abstract
A method and apparatus for detecting remote network devices. In one embodiment, the method comprises detecting an event and a) transmitting a message requesting a response from one or more remote network devices, the message comprising a first network identification code, and b) determining whether a response to the message has been received, the response transmitted by a remote network device after receiving the message and determining that the first network identification code matches a second network identification code stored within the remote network device, the response comprising identification information of the remote network device. If c) a response has not been received, terminating the method for detecting remote network devices if a pre-determined time period has elapsed since transmitting the message. If d) a response has been received, storing identification information associated with the responding remote network device and repeating steps a-d until no further responses are received.
