Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Referring to fig. 1, fig. 1 is a flowchart of a dynamic current limiting method provided in an embodiment of the present disclosure, and as shown in fig. 1, the embodiment provides a dynamic current limiting method applied to an electronic device, including the following steps:
The electronic device may be a server or middleware configured to forward the received request message, e.g., forward a message sent by the first device to the second device. The current limiting mechanism may also be referred to as a fuse mechanism, and when the current limiting mechanism is triggered, the electronic device starts a current limiting policy, that is, starts to execute the dynamic current limiting method provided by the present disclosure. The condition that the current limiting mechanism is triggered may be a forwarding success rate according to which the electronic device forwards the request message, or whether the forwarding failure rate is greater than a fusing threshold, or other conditions are adopted, which may be specifically set according to an actual situation, and the disclosure is not limited.
The first set of request messages is a set of request messages that are currently received by the electronic device (i.e., if the current limiting mechanism is triggered) and that are not forwarded. The first number can also be set according to practical situations, for example, 10 or 20, and the disclosure is not limited.
The second set of request messages is a set of request messages that are currently received by the electronic device (i.e., in a case that the request message forwarding service satisfies a preset condition) and are not forwarded.
The request message forwarding service may be a forwarding success rate of the request message, or a forwarding failure rate or other conditions, and 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, and the like. The preset condition is a target to be reached, and if the request message forwarding service meets the preset condition, it indicates that the number of request messages forwarded to the downstream needs to be continuously reduced, and the number of discarded request messages is increased.
The discarded request message may be understood as a request message that is not forwarded, which is randomly determined. The second number can also be set according to practical situations, for example, 10 or 20, and the disclosure is not limited.
Further, if the request message forwarding service still meets the preset condition, the number of more discarded request messages is increased on the basis of the second number, and so on until the request message forwarding service does not meet the preset condition.
In this embodiment, when the current limiting mechanism is triggered, a first target request message in a first request message set received by a request message forwarding service is forwarded, where the first target request message is: the first request message set removes the remaining request messages after the first number of request messages; if the request message forwarding service meets a preset condition, forwarding a second target request message in a second request message set received by the request message forwarding service, where the second target request message is: the second set of request messages excludes a second number of request messages that are left over, the second number being greater than the first number. The method can dynamically adjust the quantity of the request messages which are not forwarded (namely discarded), and improves the flexibility and the adaptability of the discarded value setting of the request messages.
In the above, in step 101, after forwarding a first target request message in a first request message set received by a request message forwarding service under the condition that a current limiting mechanism is triggered, in step 102, if the request message forwarding service meets a preset condition, before forwarding a second target request message in a second request message set received by the request message forwarding service, the method further includes:
counting the forwarding success rate of the first target request message in the first request message set;
and if the forwarding success rate is smaller than a first preset threshold value, forwarding the second target request message in the second request message set received by the request message forwarding service.
In this embodiment, the request message forwarding service may use a forwarding success rate of the first target request message as a determination criterion, and the first preset threshold may be set according to an actual situation, for example, the first preset threshold may be 85% or 90%, which is not limited herein. The preset condition is that the forwarding success rate of the first target request message is smaller than a first preset threshold, and under the condition that the request message forwarding service meets the preset condition, the number of discarded request messages is increased, namely the second number is determined, the request messages in the second request message set are forwarded according to the second number, and the second number is larger than the first number. Further, the difference between the second number and the first number may be a preset difference, that is, when the number of discarded request messages is increased, the number is increased the same each time, for example, increased by 10% each time, or increased by 20 pieces each time, which is not limited herein.
In the above, if the forwarding success rate of the first target request message is smaller than the first preset threshold, it indicates that the number of request messages forwarded to the downstream needs to be continuously decreased, that is, the number of discarded request messages is increased, so as to reduce the overload of the downstream.
In the foregoing, the counting the forwarding success rate of the first target request message in the first request message set includes:
receiving a response message of a first request message in the first target request message;
counting the number of the first request messages;
and determining the forwarding success rate according to the number of the first request messages and the number of the first target request messages.
Specifically, the electronic device forwards the first target request message to the downstream, and if the forwarding is successful, the electronic device receives a response message fed back by the downstream, and if the electronic device receives the response message, it indicates that the forwarding of the first target request message is successful. Based on this, the number of request messages successfully forwarded may be determined according to the value of the received response message of the first request message, and then the forwarding success rate may be determined according to the ratio of the number of first request messages to the number of first target request messages. The first request message is a message of the first target request message, which receives the response message.
Further, the number of the first target request messages and the number of the first request messages may be counted within a preset time period, for example, 2 seconds or 5 seconds, to determine the forwarding success rate within the preset time period.
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 the first target request messages, i.e., the forwarding success rate is determined according to the actual forwarding condition, which is convenient for dynamically adjusting the number of discarded request messages, and improves the flexibility and adaptivity of the setting of the discarded number of request messages.
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 steps are further included:
if the request message forwarding service does not meet the preset condition and the first number is greater than a second preset threshold, forwarding a third target request message in a third request message set received by the request message forwarding service, where the third target request message is: the third set of request messages excludes request messages remaining after a third number of request messages, the third number being less than the first number.
The preset condition is that the forwarding success rate is smaller than a first preset threshold, and the first preset threshold may be set according to an actual situation, for example, the first preset threshold may be 85% or 90%, and is not limited herein.
In case that the request message forwarding service does not satisfy the preset condition, for example, in case that 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 the discarded request messages is reduced, that is, a third number of the randomly discarded request messages is determined, where the third number is smaller than the first number. Further, the difference between the third quantity and the first quantity may be a preset difference. That is, when the number of discarded request messages is reduced, the number is reduced the same each time, for example, 10% each time, or 20 pieces each time, which is not limited herein. The second preset threshold may also be set according to the actual situation, for example 0.
If the success rate of forwarding the first target request message is greater than or equal to the first preset threshold, it is indicated that the number of request messages forwarded to the downstream can be increased, that is, the number of discarded request messages is reduced, as many request messages as possible are forwarded, and the forwarding performance of the electronic device is improved.
In the foregoing, when the current limiting mechanism is triggered, after forwarding a first target request message in a first request message set received by a request message forwarding service, the method further includes:
and if the message forwarding service does not meet the preset condition and the first number is less than or equal to a second preset threshold value, canceling the current limiting mechanism.
Specifically, the preset condition is that the forwarding success rate is smaller than a first preset threshold, and the first preset threshold may be set according to an actual situation, for example, the first preset threshold may be 85% or 90%, and is not limited herein.
Under the condition that the request message forwarding service does not meet the preset condition, for example, the forwarding success rate is greater than or equal to 85%, and the first quantity is less than or equal to the second preset threshold, it indicates that the request message forwarding service of the electronic device has been recovered, and the downstream overload condition is good, at this time, the current limiting mechanism is cancelled, and the electronic device resumes normal forwarding of the request message.
In this embodiment, if the message forwarding service does not satisfy the preset condition and the first number is less than or equal to a second preset threshold, the current limiting mechanism is cancelled. Namely, when the request information forwarding service of the electronic equipment is judged to be recovered, the current limiting mechanism is cancelled, and the forwarding performance of the electronic equipment can be improved.
Fig. 2 is another schematic flow chart of a dynamic current limiting method according to an embodiment of the present disclosure, and as shown in fig. 2, the dynamic current limiting method includes:
step 22, performing a blown current limiting (i.e. a dynamic current limiting policy), that is, randomly discarding X% of the request messages, which may be understood as selecting (1-X%) of the received request messages to forward, where X is a number greater than 0 and less than 100;
According to the dynamic current limiting method, the proportion of current limiting is dynamically adjusted in a self-adaptive manner, the situation that the downstream cannot be continuously in an overload state is guaranteed, the situation that the downstream is continuously in an overload avalanche state is avoided, and the self-healing capability is achieved.

Further, the dynamic current limiting apparatus 300 further includes:
and the canceling module is used for canceling the current limiting mechanism if the message forwarding service does not meet the preset condition and the first quantity is less than or equal to a second preset threshold value.
