[0067] Step 101: Obtain the current bandwidth utilization, current delay, current packet loss rate and current network card receiving ring size of a period.

[0068] It should be noted that a cycle can be measured in seconds or minutes. Bandwidth utilization is the current utilization rate of network bandwidth, measured in Mbps. Latency is the response delay of network requests, measured in milliseconds. Packet loss rate is the ratio of data packets lost in network transmission to total data packets, measured in %.

[0069] In a specific embodiment, a monitoring tool is used to obtain in real time the current bandwidth utilization, current delay, current packet loss rate and current network card receiving ring size of a period.

[0070] Step 102: Define a nonlinear function that describes the mutual influence of network states.

[0071] It should be noted that the network status includes bandwidth utilization, delay, packet loss rate and network card receiving ring size.

[0072] Step 103: Construct a nonlinear dynamic system model according to the nonlinear function.

[0073] In some embodiments, the nonlinear function includes a first nonlinear function describing the effect of the network state on the current bandwidth utilization, a second nonlinear function describing the effect of the network state on the current delay, a third nonlinear function describing the effect of the network state on the current packet loss rate, and a fourth nonlinear function describing the effect of the network state on the current network card receiving ring size;

[0074] Constructing a nonlinear dynamic system model according to the nonlinear function includes: constructing a nonlinear dynamic system model according to a first nonlinear function, a second nonlinear function, a third nonlinear function and a fourth nonlinear function.

[0075] Specifically, bandwidth utilization, delay, packet loss rate and network card receiving ring size will affect each other, and this influence is nonlinear. A nonlinear dynamic system model is constructed using nonlinear functions to describe the relationship between bandwidth utilization, delay, packet loss rate and network card receiving ring size.

[0076] Among them, use Represents the first nonlinear function, which describes the influence of current bandwidth utilization, current delay, current packet loss rate and current network card receiving ring size on current bandwidth utilization. Represents the second nonlinear function, which describes the impact of current bandwidth utilization, current delay, current packet loss rate and current network card receiving ring size on current delay. Represents the third nonlinear function, which describes the influence of current bandwidth utilization, current delay, current packet loss rate and current network card receiving ring size on the current packet loss rate. represents the fourth nonlinear function, which is used to describe the influence of the current bandwidth utilization, the current delay, the current packet loss rate and the current network card receiving ring size on the current network card receiving ring size.

[0077] In a specific embodiment, the updating process in the nonlinear dynamic system model is expressed as:

[0078] ,

[0079] ,

[0080] ,

[0081] ,

[0082] In the formula, is the first random perturbation, is the second random perturbation, is the third random perturbation, is the fourth random perturbation, is the bandwidth utilization of the next cycle, is the delay for the next cycle, is the packet loss rate of the next cycle, is the network card receiving ring size for the next cycle, is the current bandwidth utilization, is the current delay, is the current packet loss rate, The current network card receiving ring size.

[0083] in, is the time state. Use in superior, is the delay of the current cycle. Use in superior, is the delay to the next cycle.

[0084] Specifically, the first random disturbance, the second random disturbance, the third random disturbance and the fourth random disturbance are unpredictable external factors.

[0085] In a specific embodiment, the code for defining a nonlinear function that describes the mutual influence of network states is as follows:

[0086] # Define a nonlinear function for network state changes

[0087] def f1(B, L, P, R):

[0088] return B * L * 0.01 + P * 0.1 + R * 0.02

[0089] def f2(B, L, P, R):

[0090] return L * 0.5 + P * 0.2 + R * 0.03

[0091] def f3(B, L, P, R):

[0092] return P * 0.3 + B * 0.05 + R * 0.04

[0093] def f4(B, L, P, R):

[0094] return R * 0.1 + B * 0.07 + L * 0.02

[0095] Specifically, the values ​​in the code (such as 0.01, 0.1, 0.02, 0.5, etc.) are the fourth weight coefficients used to describe the mutual influence between network states. The selection of these values ​​is based on the understanding and experience of network behavior.

[0096] Among them, 0.01 (B*L*0.01): bandwidth utilization (B) and latency (L) are interrelated; higher bandwidth utilization may lead to increased latency, and increased latency will affect the efficiency of bandwidth utilization; the 0.01 here is a fourth weight coefficient, indicating that in the update per second, the impact of bandwidth utilization and latency on their own changes is relatively small.

[0097] Among them, 0.1(P*0.1): The packet loss rate (P) has a significant overall impact on bandwidth utilization (B), latency (L), packet loss rate (P) and network card receive ring size (R); a higher packet loss rate will aggravate network congestion and lead to performance degradation; the fourth weight coefficient of 0.1 indicates that the packet loss rate has a certain impact on network status changes, but it is not the dominant factor.

[0098] Among them, 0.02 (R*0.02): the short-term change of the network card receiving ring size (R) has a relatively small impact on the bandwidth utilization (B); the fourth weight coefficient of 0.02 indicates that in the current time period, the change of the network card receiving ring size has a weak impact on the bandwidth, but in the long run it may accumulate a certain impact.

[0099] Among them, 0.5 (L*0.5): the impact of delay (L) on its own future changes is more significant; higher delay will lead to further increase in subsequent delays, forming a vicious circle; the fourth weight coefficient of 0.5 means that delay has a strong impact on its own changes in each second update.

[0100] Among them, 0.2(P*0.2): the packet loss rate (P) has a certain impact on the short-term variation of the delay (L); a higher packet loss rate may cause data packet retransmission delays, which in turn affects the overall delay; the fourth weight coefficient of 0.2 indicates that the packet loss rate has a moderate impact on the delay variation.

[0101] Among them, 0.03 (R*0.03): the network card receiving ring size (R) has a relatively small impact on the short-term change of delay (L); the fourth weight coefficient of 0.03 indicates that the change of the network card receiving ring size has a weak impact on the delay in the short term, but may accumulate a certain impact in the long run.

[0102] The rest of the values ​​in the code are similar.

[0103] It should be understood that the fourth weight coefficient can be further adjusted according to the specific network environment and application scenario. Among them, when the network status is good, it is necessary to reduce the fourth weight coefficient of 0.1 (the impact of the current packet loss rate on the current bandwidth utilization) and 0.5 (the impact of the current delay on the current delay) to reduce network fluctuations. For example, 0.1 (the impact of the current packet loss rate on the current bandwidth utilization) is adjusted to 0.08, and 0.5 (the impact of the current delay on the current delay) is adjusted to 0.4.

[0104] When the network status is poor, the fourth weight coefficients of 0.1 (the impact of the current packet loss rate on the current bandwidth utilization) and 0.5 (the impact of the current delay on the current delay) need to be increased to respond to network changes more quickly. For example, 0.1 (the impact of the current packet loss rate on the current bandwidth utilization) is adjusted to 0.12, and 0.5 (the impact of the current delay on the current delay) is adjusted to 0.6. By adjusting the fourth weight coefficient, it is possible to better adapt to different network environments and achieve more accurate nonlinear dynamic system modeling.

[0105] Step 104: Based on the nonlinear dynamic system model, the network card receiving ring size of the next cycle is predicted according to the adaptive adjustment factor, the current bandwidth utilization, the current delay, the current packet loss rate and the current network card receiving ring size to obtain the predicted network card receiving ring size.

[0106] Specifically, the adaptive adjustment factor is used to perform weighted adjustment according to the influence degree of different network parameters, and the prediction result of the network card receiving ring size in the next period is optimized by adjusting the adaptive adjustment factor.

[0107] Step 105: Obtain feedback error, and adjust the adaptive adjustment factor according to the feedback error and the nonlinear function.

[0108] Specifically, the nonlinear dynamic system model is corrected by adjusting the adaptive adjustment factor, and the size of the network card receiving ring is optimized and predicted.

[0109] In some embodiments, adjusting the adaptive adjustment factor according to the feedback error and the nonlinear function includes: multiplying the learning rate, the feedback error and the nonlinear function in sequence to obtain a first intermediate value; adding the original adaptive adjustment factor to the first intermediate value to determine the adaptive adjustment factor;

[0110] It is expressed as:

[0111] ,

[0112] In the formula, is the learning rate, is the original adaptive adjustment factor, is the feedback error, is the adaptive adjustment factor.

[0113] Specifically, represents the first nonlinear function, represents the second nonlinear function, represents the third nonlinear function, represents the fourth nonlinear function, is the current bandwidth utilization, is the current delay, is the current packet loss rate, The current network card receiving ring size. For the time status. By adjusting the adaptive adjustment factor, the accuracy of the network card receiving ring test result is improved.

[0114] In some embodiments, the adaptive adjustment factor includes a first adaptive adjustment factor, a second adaptive adjustment factor, and a third adaptive adjustment factor; the learning rate includes a first learning rate, a second learning rate, and a third learning rate; the first intermediate value includes a first-intermediate value, a first-second intermediate value, and a first-third intermediate value; the original adaptive adjustment factor includes an original first adaptive adjustment factor, an original second adaptive adjustment factor, and an original third adaptive adjustment factor;

[0115] The learning rate is multiplied by the feedback error and the nonlinear function in sequence to obtain a first intermediate value; the original adaptive adjustment factor is added to the first intermediate value to determine the adaptive adjustment factor, including:

[0116] The first learning rate is multiplied by the feedback error and the first nonlinear function in sequence to obtain a first intermediate value, and the original first adaptive adjustment factor is added to the first intermediate value to determine the first adaptive adjustment factor;

[0117] The second learning rate is multiplied by the feedback error and the second nonlinear function in sequence to obtain a first intermediate value and a second intermediate value, and the original second adaptive adjustment factor is added to the first intermediate value to determine the second adaptive adjustment factor;

[0118] The third learning rate is multiplied with the feedback error and the third nonlinear function in sequence to obtain the first three intermediate values, and the original third adaptive adjustment factor is added to the first three intermediate values ​​to determine the third adaptive adjustment factor.

[0119] Specifically, by adjusting the first adaptive adjustment factor, the second adaptive adjustment factor and the third adaptive adjustment factor, the accuracy of the network card receiving ring test result is improved.

[0120] In some embodiments, based on the nonlinear dynamic system model, the network card receiving ring size of the next cycle is predicted according to the adaptive adjustment factor, the current bandwidth utilization, the current delay, the current packet loss rate and the current network card receiving ring size to obtain the predicted network card receiving ring size, including:

[0121] Based on the nonlinear dynamic system model, multiplying the first adaptive adjustment factor by the current bandwidth utilization to obtain a second intermediate value;

[0122] Multiplying the second adaptive adjustment factor by the square of the current delay to obtain a third intermediate value;

[0123] multiplying the third adaptive adjustment factor by the cube of the current packet loss rate to obtain a fourth intermediate value;

[0124] The current network card receiving ring size is sequentially added to the second intermediate value, the third intermediate value, and the fourth intermediate value to obtain the predicted network card receiving ring size;

[0125] It is expressed as:

[0126] ,

[0127] In the formula, To predict the size of the network card receiving ring, is the current network card receiving ring size, is the first adaptive adjustment factor, is the current bandwidth utilization, is the second adaptive adjustment factor, is the current delay, is the third adaptive adjustment factor, is the current packet loss rate.

[0128] in, The meaning is that a cycle is seconds, or minute. For time states, such as Use in superior, The network card receiving ring size of the current cycle. Use in superior, The predicted network card receive ring size for the next cycle.

[0129] Specifically, according to the real-time network performance, that is, the current bandwidth utilization, current delay, current packet loss rate and current network card receiving ring size, the size of the network card receiving ring is intelligently adjusted, avoiding the limitations of manual intervention in the traditional network card receiving ring test method. Through the above-mentioned real-time feedback mechanism, the size of the network card receiving ring is dynamically adjusted to ensure that the network card receiving ring value can be optimized according to the actual network load and status during the network card receiving ring test, thereby improving the accuracy of the network card receiving ring test.

[0130] In some embodiments, obtaining the feedback error includes: subtracting the current network card receiving ring size from the predicted network card receiving ring size to obtain the feedback error, which is expressed as:

[0131] ,

[0132] In the formula, To predict the size of the network card receiving ring, is the current network card receiving ring size, is the feedback error. For the time status.

[0133] It is understandable that each time the network card receiving ring size of the next cycle is predicted, the feedback error is calculated according to the predicted network card receiving ring size, and then the adaptive adjustment factor is adjusted according to the feedback error, thereby improving the accuracy of the network card receiving ring test result.

[0134] Step 106: Based on the weight coefficient, a loss function is calculated according to the bandwidth target value, the current bandwidth utilization, the current delay and the current packet loss rate, and the nonlinear dynamic system model parameters are adjusted according to the loss function.

[0135] Specifically, the loss function is used to evaluate the difference or error between the model's predicted output and the actual target value. The loss function can be minimized by continuously adjusting the model's parameters, thereby improving the model's prediction accuracy.

[0136] In some embodiments, the weight coefficients include a first weight coefficient, a second weight coefficient, and a third weight coefficient; the loss function is expressed as:

[0137] ,

[0138] In the formula, is the first weight coefficient, is the second weight coefficient, is the third weight coefficient, is the loss function, is the current packet loss rate, is the current delay, is the current bandwidth utilization, is the bandwidth target value, For the time status.

[0139] Specifically, the parameters of the nonlinear dynamic system model are adjusted according to the loss function to minimize the packet loss rate and delay and maximize the bandwidth utilization, thereby improving the accuracy of the network card receiving ring test results.

[0140] Step 107: Adjust the size of the network card receiving ring based on the predicted size of the network card receiving ring.

[0141] Reference Figure 2 As shown, adjusting the size of the network card receiving ring based on the predicted size of the network card receiving ring includes but is not limited to the following steps 201 to 202.

[0142] Step 201: Subtract the current network card receiving ring size from the predicted network card receiving ring size to obtain a judgment value.

[0143] Step 202: if the judgment value is greater than the adjustment threshold, the size of the network card receiving ring is adjusted to the predicted network card receiving ring size; otherwise, the size of the network card receiving ring is not changed.

[0144] It is understandable that the NIC receiving ring is configured and adjusted based on the predicted size of the NIC receiving ring, and an adjustment threshold is set to ensure that the NIC receiving ring is not too large or too small, thereby avoiding performance fluctuations of the NIC receiving ring due to excessive adjustment.

[0145] In a specific embodiment, the code for adjusting the size of the network card receiving ring based on the predicted size of the network card receiving ring is as follows:

[0146] # Adjust the receiving ring size

[0147] def adjust_ring_size(R, R_predicted, threshold=5):

[0148] if abs(R_predicted - R) > threshold:

[0149] R = R_predicted

[0150] return R

[0151] # Example Adjustment

[0152] def adjust_ring(R, R_predicted):

[0153] return adjust_ring_size(R, R_predicted)

[0154] It can be seen that the current bandwidth utilization, current delay, current packet loss rate and current network card receiving ring size of a cycle are obtained, a nonlinear function describing the mutual influence of network status is defined, a nonlinear dynamic system model is constructed according to the nonlinear function, and then based on the nonlinear dynamic system model, the network card receiving ring size of the next cycle is predicted according to the adaptive adjustment factor, the current bandwidth utilization, the current delay, the current packet loss rate and the current network card receiving ring size, and the predicted network card receiving ring size is obtained, and the feedback error is obtained. The adaptive adjustment factor is adjusted according to the feedback error and the nonlinear function, and the loss function is calculated according to the bandwidth target value, the current bandwidth utilization, the current delay and the current packet loss rate based on the weight coefficient. The nonlinear dynamic system model parameters are adjusted according to the loss function, and the size of the network card receiving ring is adjusted based on the predicted network card receiving ring size. According to the current bandwidth utilization, the current delay, the current packet loss rate and the current network card receiving ring size, the size of the network card receiving ring is intelligently adjusted, and the accuracy of the network card receiving ring test result is improved by optimizing and adjusting the adaptive adjustment factor and the nonlinear dynamic system model parameters.

[0155] In a specific embodiment, the startup code is as follows:

[0156] def main():

[0157] netname = "eth0" # Network card name

[0158] current_ring_size = 512 # Initial receive ring size

[0159] prev_ring_size = current_ring_size # Record the last receiving ring size

[0160] for _ in range(10): # simulate multiple iterations

[0161] print(f"\nCurrent receiving ring size: {current_ring_size}")

[0167] In a specific embodiment, when the current bandwidth utilization (B) = 80Mbps, the current delay (L) = 20ms, the current packet loss rate (P) = 1%, the current network card receiving ring size (R) = 150, the adaptive adjustment factor = [0.1, 0.05, 0.02], the learning rate = [0.01, 0.01, 0.01], and the adjustment threshold (threshold) = 5, the bandwidth target value is set to 90, the first weight coefficient, the second weight coefficient, and the third weight coefficient are set to 0.5, 0.3, and 0.2 respectively, and the network card receiving ring size is adjusted to 152.
