Abstract: A power over Ethernet (PoE)-based redundant power management method manages a redundant power supply electrically connectable to plural network devices through plural twisted pairs respectively, so as to transmit first electricity and digital information to each network device. The redundant power supply receives a power demand message from, and is informed of the electric power needed by, each network device electrically connected to the redundant power supply. In response to determining the second electricity each such network device has been receiving is interrupted, the redundant power supply outputs to each such network device the corresponding first electricity equal to the electric power needed by the network device through a corresponding Ethernet port. In response to receiving a power-off request message from any such network device, the redundant power supply stops outputting to that network device the corresponding first electricity.

Abstract: A method for preventing a verification flaw by controlling a session time and a session data traffic is applied to a networking equipment that stores a list of verified terminal devices, a temporary permit list, and a walled garden. When a terminal device is connected to the networking equipment, the networking equipment records the media information of the terminal device on the temporary permit list and starts recording a session time and session data traffic of the terminal device. Once the session time or session data traffic exceeds its upper limit (e.g., 10 minutes or 20 MB), the networking equipment cuts off connection with the terminal device, only when a frame received from the terminal device has a matching target address in the walled garden, the networking equipment will send the frame out therethrough. Thus, the terminal device, must be verified before it can access full network services.
