Background
The service degradation means that under the condition that the pressure of the server is increased sharply, some services are stopped or processed in a simple mode according to the actual business condition and flow, so that server resources are released to ensure normal or efficient operation of the servers. For example, in a video playing scenario, the more and more services are dependent, and once network jitter or a dependent service fails, the user playing experience is directly affected. At this time, service degradation needs to be performed temporarily.
In the existing method, generally, when the request amount reaches a certain preset value, the service is degraded by suspending part of user accesses, and when the access amount is lower than another preset value, the service is resumed. However, in this manner, the duration of service degradation is usually long, which results in that the access requests of some users cannot be responded for a long time, and especially for video playing and other scenes, this manner will result in that some users cannot obtain video content in time for a long time, which results in user churn.

Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to FIG. 1, a flow 100 of one embodiment of a service invocation method according to the present application is shown. The service calling method comprises the following steps:
In this embodiment, the execution subject (e.g., an electronic device such as a server) of the service invocation method may set the time period in advance. For example, every 10 seconds may be taken as a time period. Thus, 00:00:00-00:00:10 per day is the first time period; 00:00:10-00:00:20 is the second time period; and so on.
At the beginning of each time period, the executing body may obtain a failure rate of invoking the target service in the previous time period. The failure rate of calling the target service in the last time period may be a ratio of the number of times of call failure in the last time period to the total number of times of call.
It should be noted that the target service may be a service provided by another server. For example, in a video playing scenario, the target service may be a video data acquisition service or the like. Generally, the more times the target service is called, the greater the access volume to the server, and the more stressed the server is, the more likely it is to fail.
In this embodiment, the execution body may record, in real time, a result of each invocation of the target service, where the result may be success of the invocation or failure of the invocation. At the beginning of each time period, the executing body may count the failure rate of calling the target service in the last time period based on the recorded calling result in the last time period.
In some optional implementation manners of this embodiment, the execution main body may first determine the number of times of calling and the number of times of failing to call the target service in the previous time period, and then determine a failure rate of calling the target service in the previous time period based on the number of times of calling and the number of times of failing to call. Here, the failure rate of invoking the target service in the last time period may be a ratio of the number of times of invocation failure to the total number of times of invocation in the last time period.
And 102, determining the duration of the suspended calling of the target service in the current time period based on the failure rate.
In this embodiment, the execution subject may determine, based on the failure rate, a duration of suspending the call to the target service in the current time period. Here, the duration of suspending the call of the target service in the current time period may be determined according to a preset formula or rule. For example, the product of the duration of the current time period and the failure rate may be used as the duration of the suspension of the call to the target service in the current time period.
In some optional implementations of the embodiment, the execution subject may determine a duration (which may be denoted as F) for suspending invoking the target service in the current time period by:
first, a first product of the duration (which may be denoted as T) of the current time period and the failure rate (which may be denoted as s%) is determined.
And secondly, determining a second product of the first product and a preset coefficient (which can be recorded as N), and taking the second product as the duration of suspending calling the target service in the current time period.
Thus, the calculation formula of the time length for suspending the calling of the target service in the current time period can be seen as follows:
F＝T×s％×N
wherein the preset coefficient is set according to the importance of the target service. In practice, the higher the importance of the service, the larger the value of the corresponding preset coefficient is, so that the stability of the service can be ensured.
In this embodiment, the execution subject may determine one or more target time periods for suspending invoking the target service in the current time period based on the target time length. And the total duration of each target time period is equal to the target duration. The target time period is a time period for suspending the calling of the target service, that is, a time period for degrading the target service.
Because the failure rate of calling the target service in the last time period can represent the health degree of the target service in the last period of time, the greater the failure rate of calling the target service in the last time period is, the worse the health degree of the target service is, the more easily the fault occurs, and the longer the service degradation is required. Therefore, the time period for degrading the target service in the current time period is determined based on the failure rate, and the degradation time of the target service can be reasonably adjusted according to the health degree of the target service, so that the service degradation is more flexible.
In this embodiment, the execution subject may determine the target time period in the current time period by using various preset rules. As an example, one target period may be set at regular intervals. Therefore, the service degradation and recovery can be carried out for a short time for many times in the same period, the duration of each service degradation is shortened, and the timeliness of responding to the user request in the service degradation process is ensured. At the same time, the service degradation process can be made smoother.
In some optional implementations of this embodiment, the executing entity may determine the target time period in the current time period according to the following steps:
the method comprises the following steps that firstly, the current time period is divided into a plurality of time periods according to preset unit time length.
Here, the divided time periods may be fixed time periods, each of which has a duration equal to the set unit duration.
For example, the current time period is 00:00:00-00:00:10, and if 1 second is taken as a unit time length, 10 time periods of 00:00:00-00: 01, 00:00:01-00:00:02, 00:00:02-00:00:03 and the like can be divided. At this time, the number of unit time lengths included in the target time length is 10.
And secondly, determining the number of unit time lengths contained in the target time length.
Continuing with the above example, if the target duration is 4 seconds, the number of unit durations included in the target duration is 4.
And thirdly, uniformly selecting the time periods with the number from the time periods as target time periods for suspending calling the target service in the current time period.
It should be noted that, if the number of time periods cannot be uniformly selected from the plurality of time periods, the time periods can be selected approximately uniformly.
Continuing with the above example, if a non-target time period is represented by a "1" and a target time period is represented by a "0," then the 10 time periods may be represented as [1,0,1,0,1,0,1,0,1,1], where the target time periods are approximately evenly distributed in the current time cycle.
In the third step, optionally, the target time period may be determined in the following manner:
firstly, the number of unit time length contained in the target time length is added with one to obtain a target value. For example, if the number of unit time lengths included in the target time length is 4, the target value obtained by adding one is 5.
Then, a quotient of the total number of time segments in the current time period and the target value is determined. Continuing with the above example, if the number of time segments in the current time period is 10, the target value is 5, and the quotient is 2.
And finally, selecting a time period with the arrangement sequence equal to N times of the quotient from the current time period as a target time period for suspending calling the target service in the current time period, wherein N is a positive integer less than or equal to the number. Continuing with the above example, the time periods in which the rank order is equal to N times the quotient above are the 2 nd time period, the 4 th time period, the 6 th time period, and the 8 th time period. Thus, the results of [1,0,1,0,1,0,1,0,1,1] were obtained.
By uniformly selecting the target time period from the current time period, the flow (such as access requests and the like) can be uniformly transmitted to the target service, smooth degradation is further realized, and the timeliness of responding to the user request in the service degradation process is further ensured.
And step 104, in response to receiving the target request sent by the client, determining whether to invoke the target service based on the time period when the current time is in the current time cycle.
In this embodiment, in response to receiving a target request sent by a client, the execution subject may use the current time as a request time for invoking a target service, and determine whether to invoke the target service based on a time period in which the current time is located in the current time cycle.
Specifically, if the current time is in a non-target time period in the current time period, the target service may be invoked. If the current time is in the target time period in the current time cycle, the target service is not invoked. At this point, a service downgrade may be performed, suspending the invocation of the target service.
For example, a non-target time period is represented by "1", a target time period is represented by "0", 10 time periods included in the current time cycle are represented by [1,0,1,0,1,0,1,0,1,1], and each time period is 1 second. If the current time is within the first time period, it indicates that the current target service is available, and the target service may be invoked. After 3 seconds, the user's request is received again. The time at this time is in the 4 th time period, which is a target time period and represents that the current service is unavailable, and at this time, the calling of the target service is suspended.
In some optional implementations of this embodiment, in response to receiving a target request sent by a client, the execution main body may first determine whether a time period of a current time in the current time cycle is a target time period. If the target time period is not within the target time period, the target service can be called. If the target time period is reached, the alternative service can be called. Here, the alternative service may be an alternative service in which the target service is degraded.
As an example, in a video playing scene, the target request is a video data acquisition request. At this time, the target service may provide a service of acquiring the playing data of the user by a remote call, and acquiring the video data based on the playing data. The alternative service may be a service that obtains video data locally. Thereby, video data supply in the case of service degradation can be ensured.
According to the method provided by the embodiment of the application, the failure rate of calling the target service in the previous time period is obtained, then the target time length for pausing the calling of the target service in the current time period is determined based on the failure rate, and one or more target time periods for pausing the calling of the target service in the current time period are determined based on the target time length, so that when the target request sent by the client is received, whether the target service is called or not can be determined based on the time period of the current time in the current time period. Therefore, on one hand, the failure rate of calling the target service in the last time period can represent the health degree of the target service in the latest period of time, so that the time period for degrading the target service in the current time period is determined based on the failure rate, the target service can be degraded and recovered in a self-adaptive manner, and the service degradation is more flexible and timely. On the other hand, by setting the time period for the target service degradation processing in the current time period, the short-time service degradation and recovery can be performed for multiple times in the same period, the duration of each service degradation is shortened, and the timeliness of responding to the user request in the service degradation process is ensured.
With further reference to FIG. 2, a flow 200 of yet another embodiment of a service invocation method is illustrated. The flow 200 of the service invocation method includes the following steps:
In this embodiment, the execution subject (e.g., an electronic device such as a server) of the service invocation method may set the time period in advance. At the beginning of each time period, the executing body may obtain a failure rate of invoking the target service in the previous time period. The failure rate of calling the target service in the last time period may be a ratio of the number of times of call failure in the last time period to the total number of times of call.
It should be noted that step 201 may refer to step 101 in the embodiment corresponding to fig. 1, and this embodiment of the present application is not described again.
In this embodiment, the execution subject may determine, based on the failure rate, a duration of suspending the call to the target service in the current time period. Here, the duration of suspending the call of the target service in the current time period may be determined according to a preset formula or rule. For example, the product of the duration of the current time period and the failure rate may be used as the duration of the suspension of the call to the target service in the current time period. For another example, a first product of the duration of the current time period and the failure rate may be determined; and then determining a second product of the first product and a preset coefficient, and taking the second product as the duration of the suspended calling of the target service in the current time period.
It should be noted that step 202 may refer to step 102 in the embodiment corresponding to fig. 1, and details thereof are not repeated in this embodiment of the application.
In this embodiment, the execution subject may determine one or more target time periods for suspending invoking the target service in the current time period based on the target time length. And the total duration of each target time period is equal to the target duration. The target time period is a time period for suspending the calling of the target service, that is, a time period for degrading the target service.
As an example, the current time period may be first divided into a plurality of time periods according to a preset unit time length. Then, the number of unit time lengths included in the target time length is determined. And then, uniformly selecting the time periods of the number from the plurality of time periods as target time periods for suspending calling the target service in the current time period.
Because the failure rate of calling the target service in the last time period can represent the health degree of the target service in the last period of time, the greater the failure rate of calling the target service in the last time period is, the worse the health degree of the target service is, the more easily the fault occurs, and the longer the service degradation is required. Therefore, the time period for degrading the target service in the current time period is determined based on the failure rate, and the degradation time of the target service can be reasonably adjusted according to the health degree of the target service, so that the service degradation is more flexible and timely.
It should be noted that step 203 may refer to step 103 in the embodiment corresponding to fig. 1, and this embodiment of the present application is not described again.
And step 205, if not, calling the target service.
In this embodiment, if the current time is in a non-target time period in the current time cycle, that is, not in any target time period, the execution subject may invoke the target service.
As an example, in a video playing scene, the target request is a video data acquisition request. The target service is a service for acquiring the playing data of the user in a remote calling mode and acquiring the video data based on the playing data. At this time, the execution agent may perform the service provided by the target service by calling the service.
And step 206, if yes, calling the alternative service.
In this embodiment, if the current time is located in any target time period in the current time cycle, the execution subject may invoke the alternative service. At this time, the procedure of service degradation is adopted, and the calling of the target service is suspended in the procedure.
As an example, in a video playing scene, the target request is a video data acquisition request. The alternative service may be a service that obtains video data locally. Thereby, video data supply in the case of service degradation can be ensured.
As can be seen from fig. 2, compared to the corresponding embodiment of fig. 1, the flow 200 of the service invocation method in the present embodiment involves the step of invoking an alternative service when the service is downgraded. Thus, the scheme described in the present embodiment can guarantee video data supply in the case of service degradation.
With further reference to fig. 3, as an implementation of the method shown in the above-mentioned figures, the present application provides an embodiment of a service invocation apparatus, where the embodiment of the apparatus corresponds to the embodiment of the method shown in fig. 1, and the apparatus may be specifically applied to various electronic devices.

In some optional implementations of the present embodiment, the third determining unit 304 is further configured to: in response to receiving a target request sent by a client, determining whether a time period of which the current time is in the current time cycle is a target time period; if not, calling the target service; if yes, the alternative service is called.

Therefore, on one hand, the failure rate of calling the target service in the last time period can represent the health degree of the target service in the latest period of time, so that the time period for degrading the target service in the current time period is determined based on the failure rate, the target service can be degraded and recovered in a self-adaptive manner, and the service degradation is more flexible and timely. On the other hand, by setting the time period for the target service degradation processing in the current time period, the short-time service degradation and recovery can be performed for multiple times in the same period, the duration of each service degradation is shortened, and the timeliness of responding to the user request in the service degradation process is ensured.
