Abstract
A network connection retrieving method and a network system are provided. The method is adapted for retrieving connections between network devices by a master device among network devices in a local area network, and includes: attempting to establish the connection with a current device according to a pre-recorded network address of the current device; sending a plurality of broadcast packets to each of the network devices in the local area network if the step of establishing the connection failed, and collecting a response message returned from each of the network devices in response to the broadcast packets; and identifying the response message returned from the current device by comparing unique identification information recorded in each of the response messages with pre-recorded unique identification information of each of the network devices, and using the network address recorded in the response message to re-establish the connection with the current device.
