Referring to fig. 1, a schematic diagram of an ethernet parameter adaptive adjustment system according to an embodiment of the present invention is shown. The system starts to carry out self-adaptive adjustment on Ethernet parameters in a Loopback test mode.
The system comprises a data link layer, a physical layer 102, a processor and a computer program, the data link layer being connected to the physical layer 102; the data link layer comprises a first register 111 and a second register 112, wherein the first register 111 is used for storing a transmission gain value; the second register 112 is used to store the receive gain value.
In this embodiment, the data link layer is the MAC sublayer 101. The main functions of the MAC sublayer include encapsulation/de-encapsulation of data frames, addressing and identification of frames, reception and transmission of frames, management of links, error control of frames, etc.
The computer program when executed by a processor implementing the steps of:
and establishing a parameter communication configuration table, wherein the horizontal and vertical coordinates of the parameter communication configuration table respectively correspond to the transmission gain value and the receiving gain value. Of course, in other embodiments, the transmission gain value may be configured as the ordinate and the reception gain value may be configured as the abscissa.
Sequentially updating the values of the first register and the second register according to the communication configuration table, and judging whether the communication between the data link layer and the physical layer is normal or not when the values of the first register and the second register are numerical values corresponding to the coordinate points; and if so, adding identification information to the corresponding coordinate point position in the Unicom configuration table, otherwise, not adding the identification information.
The identification information may be numbers, characters, character strings, Chinese characters, etc., or may be represented by whether the graphics are filled. As indicated by the black padding in fig. 2, when the values of the first register and the second register are respectively configured to black-pad the corresponding abscissa and ordinate values, the communication between the data link layer and the physical layer is normal; conversely, white fill (i.e., the "hole" referred to below) indicates that communication between the data link layer and the physical layer is abnormal when the values of the first register and the second register are respectively configured as the abscissa and ordinate values corresponding to the white fill.
In this embodiment, the determining whether the communication between the data link layer and the physical layer is normal includes: and controlling the data link layer to send message data to the physical layer, and judging whether the data link layer can receive the same message data fed back by the physical layer. Specifically, the MAC sublayer sends the packet data to the second packet receiving interface 122 of the physical layer through the first packet sending interface 113, the physical layer transmits the packet data back to the first packet receiving interface 114 of the MAC sublayer through the second packet sending interface 121, and the MAC sublayer checks whether the communication with the physical layer is normal through "self-sending and self-receiving", that is, if the received packet data is consistent with the sent packet data, it indicates that the communication between the data link layer and the physical layer is normal; otherwise, it is abnormal.
After all coordinate points in the communication configuration table are completely traversed, determining a corresponding optimal communication area according to the distribution condition of the identification information in the communication configuration table at the moment, and selecting one coordinate point in the optimal communication area as an optimal communication point according to a preset rule; and then respectively updating the horizontal and vertical coordinates corresponding to the optimal link point to the first register and the second register.

the communication area-A1 is characterized by containing a plurality of holes, and the proportion of coordinate points with identification information in the area is generally ignored because the proportion does not exceed a preset proportion.
The communicating region-A2 is characterized by regular region and small area.
The communicating region-A3 is characterized by irregular region and larger area.
The region of communication-a 4, is characterized by often only isolated points, and such regions are generally ignored because of their small area.
Therefore, the optimal communication area in fig. 2 is A3, the optimal communication point is the center coordinate corresponding to the area A3, and the abscissa and ordinate values of the optimal communication point are the optimal values of the gain values stored in the first register and the second register.
In other embodiments, the communication area may also be other irregular shapes. After the optimal communication area (the area with the maximum area and the proportion of the coordinate points with the identification information in the selected area range exceeding the preset proportion) is selected, the average of the horizontal coordinates of all the coordinate points in the optimal communication area is taken as the updating value of the first register, and the average of the vertical coordinates of all the coordinate points in the optimal communication area is taken as the updating value of the second register, so that the optimal parameters of the gigabit Ethernet Tx register and the gigabit Ethernet Rx register are evaluated.
