Claim 4:
5. A first redundancy device in a redundancy network comprising redundancy devices, and wherein the first redundancy device comprises:
a memory configured to store instructions; and
a processor coupled to the memory, wherein when executed by the processor, the instructions cause the first redundancy device to:
generate a first supervision frame comprising first device information of the first redundancy device, wherein the first device information includes latency information between the first redundancy device and a neighbor redundancy device of the first redundancy device in the redundancy network, wherein the redundancy network is based on a High-availability Seamless Redundancy (HSR) protocol or a Parallel Redundancy Protocol (PRP), wherein the first supervision frame detects whether a second redundancy device on a transmission link on which the first redundancy device is located in the redundancy network is in a working state, and wherein the first supervision frame further comprises a link protocol data unit (LPDU) field carrying the first device information; and
send, to the second redundancy device and in a multicast manner, the first supervision frame.
