Network device and method for maintaining network connection

摘要

A method for maintaining network connection of a network device includes the following steps. Firstly, a step (a) is performed to determine whether a connection status between the network device and a remote device is disconnected. An application layer is automatically restarted if the connection status is determined to be disconnected. Then, a step (b) is performed to determine whether the connection status is still disconnected after the application layer is automatically restarted. If the connection status is still disconnected after the application layer is automatically restarted, a network protocol layer is automatically restarted. Then, a step (c) is performed to determine whether the connection status is still disconnected after the network protocol layer is automatically restarted. If the connection status is still disconnected after the network protocol layer is automatically restarted, the network device is automatically rebooted.
