Method for establishing network connection between server and network device

Номер: US20210336855A1
Автор: Chengwei Lin, Yenlun Chen
Принадлежит: QNAP Systems Inc

A method is used for establishing network connection between a server and a network device, wherein the network device uses a dynamic host configuration protocol to obtain a network address in a specific network segment. After the server obtains a parameter set related to the network device and starts to establish a network connection to the network device, whether the network connection is stable is checked. When it is determined that the network connection is unstable and the server fails to connect to the network device, the server automatically searches the network addresses in the specific network segment to locate the network device, and connects to the network device when the network device is found.
