Abstract: A network device (10) for establishing a connection with one of other network devices includes a connection switch module (100) and a connection setting module (110). The connection switch module appoints one of the other network devices with which the network device will establish a connection. The connection setting module is connected to the connection switch module for establishing a connection between the network device and the appointed one of the other network devices. The connection switch module further switches the network device to establish a connection with another one of the other network devices when the connection setting module has failed to establish a connection between the network device and the appointed one of the other network devices.

Abstract: The present invention is to provide a processing method enabling each unit in a stacking network device to utilize the functions and the Port Role Selection procedure updtRolesBridge( ) provided by the RSTP to rapidly select the port having the best priority from the stacking network device for executing STP and the relating algorithm in order to effectively reduce the working burden of the master unit through uniformly distributing the work to the slave units, which not only greatly increase the network transmission efficiency of the stacking network system, but also greatly improve the quality and speed of the network information transmission.
