Optionally, the network module reads the ID information of the PHY chip in the PHY Identifier with the address number of 3 through the IEEE802.3 protocol, and accordingly obtains an acquisition result of whether to read the ID information of the PHY chip. If the acquisition result is that the ID information is not read, that is, the ID information of the PHY chip does not exist in the network module, the characterization network module does not include the PHY chip. The network module can also read the ID information of the PHY chip in the PHY Identifier with the address number of 3 through an IEEE802.3 protocol, and correspondingly obtain the acquisition result of the ID information representing different types of the PHY chips.
Optionally, if the network module does not read the ID information of the PHY chip in the PHY Identifier, the network module may perform multiple times of reading in the PHY Identifier, and if the ID information of the PHY chip is not read after multiple times of reading, it is determined that the obtained result is the read ID information.
And S220, determining the communication mode of the network module according to the acquisition result, and carrying out communication according to the communication mode.
The communication mode comprises a first communication mode for realizing PHY-to-PHY communication of the network module through a first interface, or a second communication mode for realizing MAC-to-MAC communication of the network module through a second interface.
Optionally, different obtaining results correspond to different communication modes. If the obtained result comprises ID information of a PHY chip in the network module and ID information of a PHY chip in the network module, the corresponding communication modes comprise a first communication mode for realizing communication from the PHY chip to the PHY chip between the network module and an opposite-end network module through a first interface and a second communication mode for realizing communication from the MAC chip to the MAC chip between the network module and the opposite-end network module through a second interface, and the network module can select to adopt the first interface to carry out communication in the first communication mode with the opposite-end network module or select to adopt the second interface to carry out communication in the second communication mode with the opposite-end network module according to whether the obtained result of the ID information of the PHY chip is read or not.

s310, if the obtained result is that the ID information exists in the network module, determining whether the ID information is the target ID information supported by the network module.
The types of PHY chips supported by different network modules are different. Optionally, in a case that the obtained result is that the ID information exists in the network module, that is, the network module includes a PHY chip, it is further determined whether the PHY chip corresponding to the ID information is a PHY chip supported by the network module, that is, it is determined whether the ID information is target ID information supported by the network module.
In an optional embodiment, determining whether the ID information is target ID information supported by the network module includes:
judging whether ID information exists in a preset legal PHY ID set or not;
if so, determining that the ID information is target ID information supported by the network module.
Specifically, the network module obtains a preset legal PHY ID to form a legal PHY ID set, where the legal PHY ID is ID information of a PHY chip supported by the network module, and the network module further determines whether the preset legal PHY ID set includes ID information of the PHY chip read from the PHY Identifier, and if so, the network module determines that the read ID information is target ID information supported by the network module. If the ID information does not exist, the network module determines that the read ID information is not the target ID information supported by the network module.
And S320, if yes, determining that the communication mode is the first communication mode.
Specifically, if the network module determines that the read ID information is the target ID information supported by the network module, the communication mode of the network module is determined to be the first communication mode, that is, the network module performs PHY-to-PHY communication with the peer network module through the first interface. In addition, if the network module determines that the read ID information is not the target ID information supported by the network module, and the network module cannot communicate with the peer network module, the communication is terminated.
In an optional embodiment, if the obtained result indicates that no ID information exists in the network module and the PHY chip does not exist in the network module, it is determined that the communication mode of the network module is the second communication mode, that is, the network module performs MAC-to-MAC communication with the peer network module through the second interface. Therefore, the direct communication from the MAC chip in the network module to the MAC chip in the opposite-end network module is realized.
In an optional embodiment, the first Interface is an MDIO (Management Data Input/Output) Interface, and the second Interface is an RGMII (Reduced Gigabit Media Independent Interface) Interface. Namely, the first communication mode is that the network module carries out PHY-to-PHY communication with the opposite-end network module through the MDIO interface, and the second communication mode is that the network module carries out MAC-to-MAC communication with the opposite-end network module through the RGMII interface.

s410, acquiring an initial timestamp when the PHY chip sends the data packet through the first interface.
When the network module performs PHY-to-PHT communication with the peer network module in the first communication mode via the first interface, that is, when the PHY chip in the network module performs PHY-to-PHT communication with the PHY chip in the peer network module via the first interface, a time t1 at which the CPU in the network module controls data transmission is caused due to a complex connection relationship of the PHY chip in the network module, and a transmission delay exists between the time t2 at which the data packet passes through the PHY chip and is output by the first interface, that is, t2 is later than t1, so that the data packet output by the first interface needs to be corrected for the time delay, so as to ensure accuracy of communication time.
Specifically, when the network module sends a data packet through the first interface, the network module obtains the current time and uses the current time as the initial timestamp of the data packet.
And S420, correcting the initial timestamp by adopting a preset time correction parameter to obtain a corrected timestamp.
In the process of communication between the network module and the opposite terminal network module, there is transmission of data packets. Optionally, the preset time correction parameter is a delay time caused by transmission of the data packet through the PHY chip, and may be specifically determined according to a connection relationship of the PHY chip in the network module and stored in the network module in advance, and when it is determined that the communication mode of the network module is the first communication mode, the network module obtains the preset time correction parameter, and corrects the initial timestamp by using the preset time correction parameter, so as to obtain the corrected timestamp.
In an optional embodiment, the modifying the initial timestamp by using the preset time modification parameter to obtain a modified timestamp includes: and subtracting the preset time correction parameter from the initial timestamp to obtain a corrected timestamp.
Specifically, the preset time correction parameter is Δ T, the initial timestamp obtained when the network module sends the data packet through the first interface is T1, and the corrected correction timestamp is T2 ═ T1- Δ T.
And S430, controlling the PHY chip to send the data packet carrying the correction timestamp through the first interface.
Specifically, after the network module completes the correction of the initial timestamp of the data packet, the PHY chip is controlled to send the data packet carrying the corrected timestamp to the peer network module through the first interface.
In this embodiment, when it is determined that the communication mode of the network module is the first communication mode in which PHY is performed to PYH communication through the first interface, the network module obtains an initial timestamp when the PHY chip sends a data packet through the first interface, and corrects the initial timestamp by using a preset time correction parameter to obtain a corrected timestamp, so as to control the PHY chip to send the data packet carrying the corrected timestamp to the peer end through the first interface, thereby eliminating/reducing transmission delay caused by the PHY chip, and improving the communication accuracy of the first communication mode.
