Claim 8:
9. A computer program product comprising computer-executable instructions that are stored on a non-transitory computer-readable medium and that, when executed by a processor, cause a redundancy device in a redundancy network to:
generate a first supervision frame comprising first device information of a 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 redundancy devices and in a multicast manner, the first supervision frame.
