[0022] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0023] See also Figure 1 , Figure 1 is a flow chart of a dynamic current limiting method provided by an embodiment of the present disclosure, such as Figure 1 As shown, this embodiment provides a dynamic current limiting method, which is applied to electronic equipment and includes the following steps:

[0024] Step 101: When a current limiting mechanism is triggered, forwarding a first target request message in a first request message set received by a request message forwarding service, wherein the first target request message is: the request messages remaining after removing a first number of request messages from the first request message set.

[0025] The electronic device may be a server or a middleware, and the server or the middleware is used to forward the received request message, for example, forwarding the message sent by the first device to the second device. The current limiting mechanism may also be referred to as a fuse mechanism. When the current limiting mechanism is triggered, the electronic device turns on the current limiting strategy, that is, starts to execute the dynamic current limiting method provided by the present disclosure. The condition for triggering the current limiting mechanism may be based on the forwarding success rate of the electronic device forwarding the request message, or whether the forwarding failure rate is greater than the fuse threshold, or other conditions may be adopted, which may be set according to the actual situation, and the present disclosure does not limit it.

[0026] The first request message set is a set of request messages currently received and not forwarded by the electronic device (ie, when the current limiting mechanism is triggered). The first number can also be set according to actual conditions, such as 10 or 20, which is not limited in this disclosure.

[0027] Step 102: If the request message forwarding service meets the preset conditions, the second target request message in the second request message set received by the request message forwarding service is forwarded, and the second target request message is: the request messages remaining after the second request message set is removed from the second number of request messages, and the second number is greater than the first number.

[0028] The second request message set is a set of request messages that are currently received by the electronic device (ie, when the request message forwarding service meets the preset conditions) and have not been forwarded.

[0029] The request message forwarding service may be a forwarding success rate of the request message, or a forwarding failure rate or other conditions. The preset conditions may be preset, for example, the forwarding success rate is greater than a preset threshold or less than a preset threshold, or the forwarding failure rate is greater than a preset threshold or less than a preset threshold, etc. The preset conditions are goals to be achieved. If the request message forwarding service meets the preset conditions, it means that the number of request messages forwarded to the downstream needs to be further reduced, and the number of discarded request messages needs to be increased.

[0030] The discarded request message can be understood as a request message that is not forwarded, and the request message that is not forwarded is determined randomly. The second number can also be set according to actual conditions, such as 10 or 20, which is not limited in the present disclosure.

[0031] Further, if the request message forwarding service still meets the preset condition, the number of more discarded request messages is increased based on the second number, and so on, until the request message forwarding service does not meet the preset condition.

[0032] In this embodiment, when the current limiting mechanism is triggered, the first target request message in the first request message set received by the request message forwarding service is forwarded, and the first target request message is: the request message remaining after the first number of request messages are removed from the first request message set; if the request message forwarding service meets the preset conditions, the second target request message in the second request message set received by the request message forwarding service is forwarded, and the second target request message is: the request message remaining after the second number of request messages are removed from the second request message set, and the second number is greater than the first number. The above method can dynamically adjust the number of request messages that are not forwarded (i.e., discarded), and improve the flexibility and adaptability of setting the request message discard value.

[0033] In the above, in step 101, when the current limiting mechanism is triggered, after forwarding the first target request message in the first request message set received by the request message forwarding service, in step 102, if the request message forwarding service meets the preset conditions, before forwarding the second target request message in the second request message set received by the request message forwarding service, it also includes:

[0034] Counting the forwarding success rate of the first target request message in the first request message set;

[0035] Step 102: If the request message forwarding service meets a preset condition, forwarding the second target request message in the second request message set received by the request message forwarding service includes:

[0036] If the forwarding success rate is less than a first preset threshold, the second target request message in the second request message set received by the request message forwarding service is forwarded.

[0037] In this embodiment, the request message forwarding service can use the forwarding success rate of the first target request message as a basis for determination. The first preset threshold value can be set according to actual conditions. For example, the first preset threshold value can be 85% or 90%, which is not limited here. The preset condition is that the forwarding success rate of the first target request message is less than the first preset threshold value. When the request message forwarding service meets the preset condition, the number of discarded request messages is increased, that is, the second number is determined, and the request messages in the second request message set are forwarded according to the second number, and the second number is greater than the first number. Furthermore, the difference between the second number and the first number can be a preset difference, that is, when increasing the number of discarded request messages, the number increased each time is the same, for example, 10% each time, or 20 each time, which is not limited here.

[0038] In the above, if the forwarding success rate of the first target request message is less than the first preset threshold, it means that the number of request messages forwarded to the downstream needs to be further reduced, that is, the number of discarded request messages needs to be increased to reduce the downstream overload.

[0039] In the above, the counting of the forwarding success rate of the first target request message in the first request message set includes:

[0040] Receiving a response message to the first request message in the first target request message;

[0041] Counting the number of the first request messages;

[0042] The forwarding success rate is determined according to the number of first request messages and the number of the first target request messages.

[0043] Specifically, if the electronic device forwards the first target request message to the downstream successfully, it will receive a response message fed back by the downstream. If the electronic device receives the response message, it indicates that the first target request message is forwarded successfully. Based on this, the number of request messages that are forwarded successfully can be determined based on the value of the response message to the received first request message, and then the forwarding success rate can be determined based on the proportion of the number of first request messages to the number of first target request messages. Among them, the first request message is the message that receives the response message in the first target request message.

[0044] Furthermore, the number of first target request messages and the number of first request messages within a preset time period, such as 2 seconds or 5 seconds, may be counted to determine the forwarding success rate within the preset time period.

[0045] In this embodiment, the forwarding success rate is determined by the number of successfully forwarded request messages (i.e., the first request messages) and the number of first target request messages. That is, the forwarding success rate is determined based on the actual forwarding situation, which facilitates dynamic adjustment of the number of discarded request messages and improves the flexibility and adaptability of setting the number of discarded request messages.

[0046] In the above, in step 101, when the current limiting mechanism is triggered, after forwarding the first target request message in the first request message set received by the request message forwarding service, the following is also included:

[0047] If the request message forwarding service does not meet the preset conditions and the first quantity is greater than the second preset threshold, the third target request message in the third request message set received by the request message forwarding service will be forwarded, and the third target request message is: the request messages remaining after removing the third quantity of request messages from the third request message set, and the third quantity is less than the first quantity.

[0048] The preset condition is that the forwarding success rate is less than a first preset threshold value. The first preset threshold value can be set according to actual conditions. For example, the first preset threshold value can be 85% or 90%, which is not limited here.

[0049] When the request message forwarding service does not meet the preset conditions, for example, when the forwarding success rate is greater than or equal to 85%, and the first number is greater than the second preset threshold, the number of discarded request messages is reduced, that is, a third number of randomly discarded request messages is determined, and the third number is less than the first number. Furthermore, the difference between the third number and the first number may be a preset difference. That is, when reducing the number of discarded request messages, the number of reductions is the same each time, for example, 10% each time, or 20 each time, which is not limited here. The second preset threshold can also be set according to actual conditions, for example, 0.

[0050] If the forwarding success rate of the first target request message is greater than or equal to the first preset threshold, it means that the number of request messages forwarded to the downstream can be increased, that is, the number of discarded request messages can be reduced, and as many request messages as possible can be forwarded to improve the forwarding performance of the electronic device.

[0051] In the above, when the current limiting mechanism is triggered, after forwarding the first target request message in the first request message set received by the request message forwarding service, the method further includes:

[0052] If the message forwarding service does not meet the preset conditions and the first number is less than or equal to a second preset threshold, the current limiting mechanism is canceled.

[0053] Specifically, the preset condition is that the forwarding success rate is less than a first preset threshold value, and the first preset threshold value can be set according to actual conditions. For example, the first preset threshold value can be 85% or 90%, which is not limited here.

[0054] When the request message forwarding service does not meet the preset conditions, for example, when the forwarding success rate is greater than or equal to 85%, and the first number is less than or equal to the second preset threshold, it means that the request message forwarding service of the electronic device has been restored and the downstream overload situation has improved. At this time, the current limiting mechanism is canceled and the electronic device resumes normal forwarding of request messages.

[0055] In this embodiment, if the message forwarding service does not meet the preset condition and the first number is less than or equal to the second preset threshold, the current limiting mechanism is canceled. That is, when it is determined that the request information forwarding service of the electronic device is restored, the current limiting mechanism is canceled to improve the forwarding performance of the electronic device.

[0056] like Figure 2 FIG. 1 is another flow chart of the dynamic current limiting method provided by an embodiment of the present disclosure. Figure 2 As shown, the dynamic current limiting method includes:

[0057] Step 21, triggering the fuse mechanism (i.e., current limiting mechanism);

[0058] Step 22, execute fuse current limiting (i.e., dynamic current limiting strategy), that is, randomly discard X% of request messages. This step can be understood as selecting (1-X%) request messages from the received request messages for forwarding, where X is a number greater than 0 and less than 100;

[0059] Step 23, detecting the forwarding success rate of the request message forwarded N times (or pieces), and judging whether the request message forwarding service is restored according to the forwarding success rate;

[0060] Step 24, determining whether the request message forwarding service is restored, for example, if the forwarding success rate is greater than or equal to the first preset threshold, it is restored, and if the forwarding success rate is less than the first preset threshold, it is not restored; if it is not restored, go to step 25 for execution; if it is restored, go to step 26 for execution;

[0061] Step 25, increasing the discard ratio, that is, increasing the preset value based on X, and going to step 22 for execution;

[0062] Step 26, determine whether X is 0, if it is 0, execute step 27; if not 0, execute step 28;

[0063] Step 27, cancel the fuse;

[0064] Step 28, reducing the discard ratio, that is, reducing the preset value based on X, and then going to step 22 for execution.

[0065] The above-mentioned dynamic current limiting method ensures that the downstream will not be in an overload state continuously by adaptively and dynamically adjusting the current limiting ratio, avoids the downstream from being in an overload avalanche state continuously, and has self-healing ability.

[0066] See also Figure 3 , Figure 3 is a structural diagram of a dynamic current limiting device provided in an embodiment of the present disclosure, such as Figure 3 As shown, this embodiment provides a dynamic current limiting device 300, including:

[0067] A first forwarding module 301 is configured to forward a first target request message in a first request message set received by a request message forwarding service when a current limiting mechanism is triggered, wherein the first target request message is: the remaining request message after removing a first number of request messages from the first request message set;

[0078] Furthermore, the dynamic current limiting device 300 further includes:

[0079] A cancellation module is used to cancel the current limiting mechanism if the message forwarding service does not meet the preset conditions and the first number is less than or equal to a second preset threshold.

[0080] The dynamic current limiting device 300 of the embodiment of the present disclosure, when the current limiting mechanism is triggered, forwards the first target request message in the first request message set received by the request message forwarding service, the first target request message being: the request message remaining after the first number of request messages are removed from the first request message set; if the request message forwarding service meets the preset conditions, forwards the second target request message in the second request message set received by the request message forwarding service, the second target request message being: the request message remaining after the second number of request messages are removed from the second request message set, the second number being greater than the first number. The above method can dynamically adjust the number of request messages that are not forwarded (i.e., discarded), and improve the flexibility and adaptability of setting the value of request message discard.
