摘要： A clock port attribute recovery method includes a network device setting a value of a port attribute of a clock port of the network device to a first value based on the clock port not receiving any one of three types of clock messages: N synchronization messages, follow-up messages, and delay response messages within a timeout interval, where the first value indicates that a message is lost on the clock port. Based on a case that a recovery condition is met, the network device sets the value of the port attribute of the clock port to a second value, where the second value indicates that a status of the clock port is that the message is not lost.

摘要： A device location sensing method obtains locations of N devices in a wireless network based on channel state information (CSI). Each device in the wireless network has M antennas arranged in a non-linear manner. To determine the device locations, CSI data mutually detected between every two devices in N devices is obtained and used to calculate an angle difference of arrival (ADoA) set which includes, for every two devices in the N devices relative to each of the other devices in the N devices, an ADoA that is a difference between angles of arrival (AoAs) of the two devices relative to the other device. Relative locations of the N devices are then calculated based on the ADoA set.
