[0021] See also Figure 1 , Figure 1 A flow chart of a data transmission optimization method based on a high-performance CPO switch provided in an embodiment of the present application is shown as follows: Figure 1 As shown, the data transmission optimization method based on a high-performance CPO switch provided in an embodiment of the present application includes steps S1 to S5.

[0022] Step S1: Obtain the source MAC address and destination MAC address of the data to be transmitted.

[0023] Step S2: Generate a switch adjacency mapping table based on the start MAC address and the target MAC address.

[0024] Step S3: Generate multiple initial transmission links based on the start MAC address, the target MAC address and the switch adjacency mapping table.

[0025] Step S4: For each of the initial transmission links, generate the network quality index of the initial transmission link based on a preset network quality index generation method, generate the transmission overhead index of the initial transmission link based on a preset transmission overhead index generation method, and generate the link quality index of the initial transmission link based on the network quality index and the transmission overhead index.

[0026] Step S5: determining a target transmission link among the initial transmission links based on the link quality index of each of the initial transmission links, and transmitting the data to be transmitted based on the target transmission link.

[0027] It should be noted that the execution subject of this embodiment can be a server or a data transmission optimization system based on a high-performance CPO switch. The following description will be made using a server as an example.

[0028] In this embodiment, it specifically includes: In the above step S1, after receiving the transmission instruction of the data to be transmitted, the server parses the data message of the data to be transmitted to obtain the starting MAC address and the target MAC address of the data to be transmitted, and the data to be transmitted is transmitted from the starting MAC address to the target MAC address.

[0029] In the above step S2, after obtaining the start MAC address and the target MAC address, the server generates the switch adjacency mapping table based on the switch topology diagram between the start MAC address and the target MAC address.

[0030] In the above step S3, the server generates a plurality of initial transmission links based on the start MAC address, the target MAC address and the switch adjacency mapping table.

[0031] In the above-mentioned step S4, for each of the initial transmission links, the server first generates a network quality index of the initial transmission link based on a preset network quality index generation method, and then generates a transmission overhead index of the initial transmission link based on a preset transmission overhead index generation method. Finally, the network quality index and the inverse of the transmission overhead index are weightedly summed to obtain the link quality index of the initial transmission link; wherein, the weight coefficient corresponding to the network quality index is greater than the weight coefficient corresponding to the inverse of the transmission overhead index.

[0032] In the above step S5, the initial transmission link corresponding to the maximum link quality index is determined as the target transmission link, and the data to be transmitted is transmitted based on the target transmission link.

[0033] The method provided in this embodiment, first, dynamically generates a switch adjacency mapping table, and generates multiple initial transmission links in combination with the starting MAC address and the target MAC address, thereby solving the problem that the traditional static link selection strategy cannot adapt to the dynamic network environment and providing basic support for link optimization. Then, for each initial transmission link, based on the preset network quality index generation method and transmission overhead index generation method, the network quality index and transmission overhead index are calculated respectively, and the performance status and transmission cost of the link are comprehensively evaluated, ensuring the scientific nature and accuracy of the link selection. Secondly, by performing a weighted summation on the inverse of the network quality index and the transmission overhead index, a link quality index is generated, and the target transmission link with the highest link quality index is preferentially selected, which effectively balances the relationship between network performance and transmission overhead, and helps to improve the efficiency and stability of data transmission.

[0034] In some embodiments, the generating of the network quality index of the initial transmission link based on a preset network quality index generating method includes the following steps: Obtaining network quality information between each sub-transmission link of the initial transmission link, wherein a link between two adjacent switches of the initial transmission link constitutes a sub-transmission link of the initial transmission link, and the network quality information includes available bandwidth, delay duration, and packet loss rate; Generating a transmission capability index based on each of the available bandwidths, generating a transmission rate index based on each of the delay durations, and generating a transmission stability index based on each of the packet loss rates; The transmission capability index, the transmission rate index and the transmission stability index are weighted and summed to obtain the network quality index; wherein the weight coefficient of the transmission stability index is greater than the weight coefficient of the transmission capability index, and the weight coefficient of the transmission capability index is greater than the weight coefficient of the transmission rate index.

[0035] The method provided in this embodiment first provides an accurate data basis for link quality assessment by separately obtaining network quality information for each sub-transmission link of the initial transmission link. Then, a transmission capacity index is generated based on the available bandwidth, a transmission rate index is generated based on the delay duration, and a transmission stability index is generated based on the packet loss rate. This quantifies the performance characteristics of the link from multiple dimensions, ensuring the scientific and comprehensive nature of the assessment results. Finally, a network quality index is generated by performing a weighted summation of the transmission capacity index, the transmission rate index, and the transmission stability index. Combined with the reasonable allocation of weight coefficients, this effectively balances the stability, throughput, and transmission efficiency of the link.

[0036] The step of generating a transmission capability index based on each available bandwidth, generating a transmission rate index based on each delay duration, and generating a transmission stability index based on each packet loss rate comprises the following steps: Calculating a first standard deviation between the available bandwidths, and determining a ratio between a maximum available bandwidth among the available bandwidths and the first standard deviation as the transmission capability index; Calculating the sum of the delay durations, and determining the reciprocal of the sum of the delay durations as the transmission rate index; A second standard deviation between the packet loss rates is calculated, and a reciprocal of a product of the second standard deviation and a minimum packet loss rate among the packet loss rates is determined as the transmission stability index.

[0037] It can be understood that the above-mentioned method of generating a transmission capacity index based on each available bandwidth, generating a transmission rate index based on each delay period, and generating a transmission stability index based on each packet loss rate, first, by calculating the first standard deviation between the available bandwidths of each sub-transmission link, and using the ratio of the maximum available bandwidth to the first standard deviation as the transmission capacity index, it is possible to effectively reflect the bandwidth fluctuation of the link. Then, by calculating the sum of the delay periods of each sub-transmission link, and using the inverse of the sum of the delay periods as the transmission rate index, it is possible to intuitively evaluate the transmission speed of the link. Finally, by calculating the second standard deviation between the packet loss rates of each sub-transmission link, and using the inverse of the product of the second standard deviation and the minimum packet loss rate as the transmission stability index, it is possible to accurately measure the transmission reliability of the link.

[0038] In some embodiments, generating the transmission cost index of the initial transmission link based on a preset transmission cost index generation method includes the following steps: Obtaining the MTU of each switch in the initial transmission link, determining the minimum MTU among the MTUs as the target MTU, and subtracting IP header bytes from the target MTU to obtain the payload of each switch; wherein the MTU is the maximum transmission unit; Obtaining a total number of bytes of the data to be transmitted, and determining a number of fragments of the data to be transmitted based on the total number of bytes and the payload; specifically, rounding up a ratio between the total number of bytes and the payload to obtain the number of fragments; Determine the product of the number of fragments and the IP header bytes as the protocol header byte overhead; Determine the sum of the delay durations of the sub-transmission links of the initial transmission link as the single-slice transmission delay duration; a link between two adjacent switches of the initial transmission link constitutes a sub-transmission link of the initial transmission link; Determining a reassembly delay based on the number of fragments and the single-fragment transmission delay; specifically, subtracting 1 from the number of fragments to obtain a difference in the number of fragments, and determining the product of the difference in the number of fragments and the single-fragment transmission delay as the reassembly delay; For each fragment of the data to be transmitted, a transmission success probability corresponding to the fragment is generated based on the packet loss rate corresponding to each sub-transmission link; specifically, by Generate the transmission success probability; wherein, is the transmission success probability, Indicates that the initial transmission link includes sub-transmission links, Indicates the The corresponding packet loss rate of each sub-link; The retransmission probability of the initial transmission link is generated based on the transmission success probability corresponding to each of the fragments; specifically, by Generate a retransmission probability of the initial transmission link; wherein, is the retransmission probability, Indicates the number of shards; The transmission overhead index is generated based on the protocol header byte overhead, the reassembly delay duration, and the retransmission probability.

[0039] It can be understood that the above-mentioned method of generating the transmission overhead index of the initial transmission link based on the preset transmission overhead index generation method, first, by obtaining the minimum MTU of each switch in the initial transmission link and calculating the effective load in combination with the IP header bytes, the fragmentation requirements of the data packet can be accurately evaluated, thereby providing basic data support for subsequent transmission overhead calculations. Then, based on the total bytes and effective load of the data to be transmitted, the number of fragments is determined, and the protocol header byte overhead is calculated, which can quantify the additional data volume overhead brought by fragmented transmission, providing an important basis for optimizing link selection. Secondly, by calculating the single-fragment transmission delay of the initial transmission link and determining the reassembly delay in combination with the number of fragments, the impact of fragmented transmission on delay can be comprehensively evaluated. Finally, by generating the fragment transmission success probability based on the packet loss rate of the sub-transmission link, and further calculating the retransmission probability of the initial transmission link, a scientific basis is provided for selecting a low-overhead, high-efficiency transmission link, which significantly improves the stability and performance of data transmission.

[0040] The step of generating the transmission overhead index based on the protocol header byte overhead, the reassembly delay duration, and the retransmission probability comprises the following steps: Determining whether the retransmission probability is greater than a preset retransmission probability; If so, determining that the transmission overhead index is infinite; If not, calculating the sum of the bytes between the protocol header byte overhead and the total bytes, and determining a ratio of the protocol header byte overhead to the sum of the bytes as a byte overhead index; pass Generates a time overhead index; where, is the time cost index, is the reorganization delay duration, is the single-slice transmission delay; Determining the retransmission probability as a retransmission overhead index; The byte overhead index, the time overhead index and the retransmission overhead index are weighted and summed to obtain the transmission overhead index; wherein, the weight coefficient of the retransmission overhead index is greater than the weight coefficient of the byte overhead index, and the weight coefficient of the byte overhead index is greater than the weight coefficient of the time overhead index.

[0041] It can be understood that the above-mentioned method of generating the transmission overhead index based on the protocol header byte overhead, the reassembly delay and the retransmission probability, first, by judging whether the retransmission probability is greater than the preset retransmission probability and directly marking the situation exceeding the threshold as infinite overhead, can effectively eliminate links with high retransmission risks and avoid performance degradation and resource waste caused by frequent retransmissions. Then, by calculating the ratio between the protocol header byte overhead and the total bytes to generate the byte overhead index, it can quantify the additional data volume overhead brought by fragmented transmission, providing an important basis for evaluating the data transmission efficiency of the link. Secondly, by generating the time overhead index based on the reassembly delay and the single-fragment transmission delay, it can accurately evaluate the impact of fragmented transmission on delay. Finally, by performing weighted summation of the byte overhead index, the time overhead index and the retransmission overhead index to generate the transmission overhead index, and combining with the reasonable allocation of weight coefficients, it can comprehensively and scientifically evaluate the transmission overhead of the link, providing an accurate basis for selecting low-overhead, high-efficiency transmission links, and significantly improving the stability and performance of data transmission.
