It can be understood that in some embodiments, in at least one message received by the switching device, each message contains type characterization information, so the switching device can directly extract a corresponding type from each message. Characterization information, that is, at least one type of characterization information is extracted from at least one message. Specific types of characterization information are not limited in the embodiments of the present application.

In some embodiments, the type characterization information may be a destination physical (Media Access Control, MAC) address, or Ethernet protocol type and source port information.

In some embodiments, the type characterization information is a destination physical address, and the switching device may directly extract at least one destination physical address from at least one message, that is, the switching device extracts the corresponding destination of the message from each message. Physical address.

In some embodiments, the type characterization information is Ethernet protocol type and source port information, and the switching device can directly extract at least one Ethernet protocol type and at least one source port information from the at least one message, that is, the switching device The packet extracts the Ethernet protocol type and source port information corresponding to the packet.

S203. According to at least one type characterization information, from at least one message, determine a clock message whose message type is a clock type, and obtain receiving port information corresponding to the clock message.

In some embodiments, after the switching device extracts at least one type of characterization information from the at least one message, it may determine, based on the at least one type of characterization information, from at least one message, a clock message with a message type of clock type. And obtain the receiving port information corresponding to the clock message.

In some embodiments, since the switching device can extract different types of characterization information, a clock message with a message type of clock type can be determined from at least one message according to different methods.

In some embodiments, the type characterization information is a destination physical address, and the switching device matches at least one destination physical address corresponding to the at least one message with a preset destination physical address from at least one message to obtain at least one matching result.
