The embodiment of the application provides a pressure test flow scheduling method, which can obtain a plurality of flow control rules, then generate a timing task according to the flow control rules, and send the timing task to a pressure applying device so that the pressure applying device outputs flow for pressure test at a timing time according to the flow information.
When the stress test traffic scheduling method is implemented, the implementation of the main body thereof may include, but is not limited to, implementations such as a network host, a single network server, multiple network server sets, or a computer set based on cloud computing. Here, the Cloud is made up of a large number of hosts or web servers based on Cloud Computing (Cloud Computing), which is a type of distributed Computing, one virtual computer consisting of a collection of loosely coupled computers.
Fig. 1 shows a method for scheduling a stress test flow provided by an embodiment of the present application, where the method includes:
in step S101, a plurality of flow control rules are acquired. The flow control rule contains relevant information for determining the flow rate of the pressure test performed by the pressure applying device at a specific time, for example, the flow control rule may be that the test flow rate is increased or decreased by a preset value at a specific time, or the flow rate is adjusted accordingly when the current flow rate satisfies what condition, etc.
And step S102, generating a timing task according to the plurality of flow control rules, wherein the timing task comprises flow information of timing time. The timing task can be provided for the pressure applying equipment, so that the pressure applying equipment is controlled to output the flow for pressure test at the timing time according to the flow information, and therefore for a user, only a plurality of flow control rules need to be input once when the pressure test task is created, so that the timing task is combined, the pressure applying equipment can be controlled to simulate a complex scene with frequently changed flow according to the flow information, and the pressure test conforming to an actual scene can be conveniently realized.
In some embodiments of the present application, the timing task generated by combining the plurality of flow control rules includes flow information of a timing time, the timing time being a time point determined based on the flow control rules at which an adjustment of the flow of the pressure test is required, and the flow information of the timing time being a flow value adjusted at the adjusted time point. For example, in the embodiment of the present application, a timing task t1 is to adjust the flow rate of the pressure test to 1000 at the time point of 16:30:20, so that the flow rate information of the included timing time is: 16:30:20, 1000, it is understood that the flow rate is set to 1000 at this point in time 16:30: 20.
In an actual scenario, the number of timing tasks that can be determined based on the flow control rule may be multiple, and thus the flow rate of the pressure test may be continuously adjusted for the timing time corresponding to the multiple timing tasks, so that a complex scenario in which the flow rate frequently changes is simulated. In some embodiments of the present application, each flow control rule includes at least first rule information for determining a timing time and second rule information for determining flow information.
The timing time required to adjust the flow may be determined by the first rule information, and may include, for example, a delay time, an interval time, an execution number, and the like, where the delay time refers to a time when the flow adjustment is first performed, the first timing time corresponding to the flow control rule may be determined, the interval time refers to an interval of each subsequent execution, the subsequent timing time corresponding to the flow control rule may be determined, the execution number refers to a number of times when the flow adjustment is performed based on the flow control rule, and the number of timing times corresponding to the flow control rule may be determined. In a specific case, if the execution is required to be always executed, the execution times can be set to be infinite. For example, if the first rule information of a certain flow control rule includes information of delay time, time interval, and execution times of 200s, 10s, and 100 times, respectively, it can be determined that after the first timing time of the timing task corresponding to the flow control rule is 200 seconds, each of the subsequent 10 seconds is a timing time, such as 210 seconds, 220 seconds … …, and the like, the total of 100 times is executed.
The flow value adjusted at each timing time may be determined by the second rule information, and may include, for example, an adjustment rule, an initial value, and the like. The adjustment rule is a calculation rule for adjusting the flow rate value at each timing time, and may be, for example, a rule related to time, a rule related to historical flow, or a binary dynamic parameter rule related to both time and historical flow. In practical scenarios, the adjustment rule may be expressed in a function expression related to time and/or historical flow, for example, 600+500 · sin (t/240 · 2 · pi) may represent a flow adjustment rule in a sine wave form related to time, last +50 may represent an adjustment rule in an incremental form related to historical flow (last adjusted flow value), and if (last > 50) the return 50 may represent an adjustment rule in a conditional decision form related to historical flow. The initial value may be used to set the flow value at the time of the first adjustment, and may be used in combination with a partial adjustment rule to complete the adjustment of the flow, for example, the initial value of the flow may be set to 50.
Therefore, the flow control rule comprises the first rule information and the second rule information, and the corresponding timing task can be analyzed.
And step S103, sending the timing task to a pressure applying device so that the pressure applying device outputs flow for pressure testing according to the flow information at a timing time. Because the flow control rules are mutually independent, corresponding timing tasks can be determined, each timing task is used for correspondingly adjusting the flow in the corresponding timing time, and a complex flow change scene can be simulated after the timing tasks are combined, so that the pressure test conforming to the actual scene is realized.
In some embodiments of the present application, when obtaining a plurality of flow control rules, an original rule input by a user may be obtained first, and then an orchestration task set may be obtained by parsing according to the original rule. The arrangement task set comprises a plurality of arrangement tasks which are independent from each other, and each arrangement task comprises a corresponding flow control rule. For example, the original rule R provided by the user may be in the form of a character string, and after the device obtains the character string, the device may obtain an arrangement task set by parsing the character string, where each arrangement task in the arrangement task set has a respective attribute. These attributes may represent the first rule information and the second rule information, thereby constituting a flow control rule for each orchestration task. For example, in the present embodiment, the orchestration task set obtained by parsing the original rule may include orchestration tasks r1, r2, and r3, each of which includes the following attributes: latency, interval, scheduling rules, number of executions, whether to execute forever, whether to reset, initialization values, etc.
Taking r1 as an example, the delay time is 10s, the interval time is 10s, the execution times is 5, and whether the execution is always performed is no, the arrangement rule is: last +10, if reset is true, the initialization value is 20, where the delay time, interval time, execution times, and whether to execute the first rule information that can constitute the flow control rule forever, and the scheduling rule, whether to reset, and the initialization value constitute the second rule information in the flow control rule. And the delay time in the attribute of the scheduling task r2 is 60s, the interval time is 10s, the execution times is 5, and whether the execution is always negative is determined as follows: last-10, if the reset is no, the initialization value is null; the delay time of the attribute of the orchestration task r3 is 110s, the interval time is 10s, the execution times is 5, and whether the execution is always yes or not, the orchestration rule is: last + t/10, if the reset is no, the initialization value is null. Therefore, based on the arrangement task set obtained by analyzing the original rule R, a total of 15 timing tasks can be determined, and the timing time corresponding to the timing tasks is respectively 10s, 20s, 30s, … …, 140s and 150 s. After the timing task is sent to the pressure applying device, the pressure applying device can output the flow rate for the pressure test at the timing time according to the flow rate information, and fig. 2 is a schematic diagram of the flow rate for the pressure test in this embodiment.
In an actual scenario, different scheduling task sets can be obtained according to different original rules R, wherein flow control information included in the scheduling tasks is also different, so that various different flow change situations can be combined, for example, fig. 3 to 6 are schematic diagrams of flow change situations simulated by using the scheme provided by the embodiment of the present application to implement flow scheduling during pressure testing, so that flow change scenarios including periodicity, impulse and other high correlation with time series can be simulated.
In some embodiments of the present application, the scheduling device generates a timing task according to the plurality of flow control rules, and then sends the timing task to the pressure applying device, so that the pressure applying device outputs a flow for pressure testing according to the flow information at a timing time. In a practical scenario, the dispatching device may generate timing tasks one by one or batch by batch and send the timing tasks to the pressure applying device for execution, so that a short-time high load caused by generating all timing tasks at the same time may be avoided in a complex scenario. In this embodiment, it may be determined whether a next timing time exists based on the current time, and when the next timing time exists, a first timing task corresponding to the next timing time may be generated according to the flow control rule, where the first timing task includes flow information of the next timing time. For example, taking the above-mentioned scheduling task set including scheduling tasks r1, r2, and r3 as an example, if the current time is the start time 9:00:00 of the current pressure test, it can be known that the next timing time is 9:00:10, and the flow value corresponding to the time is last + 10: 30, so that it can be determined that the first timing task t is to adjust the flow rate of the pressure test to 30 at 9:00: 10.
In this scenario, the scheduling device sends the first timing task to the pressure applying device after the next timing time of the first timing task is reached, so that the pressure applying device outputs a flow rate for pressure testing according to the flow rate information. After the scheduling device sends the first timing task to the pressure applying device, the pressure applying device may receive and process information included in the first timing task, and adjust the generated flow rate by the asynchronous pressure measurement engine at the next timing 9:00: 10. The scheduling device may continue to attempt to generate a new first timing task while sending the first timing task, that is, continue to determine whether a next timing time exists based on the current time (9:00:10), and when the next timing time exists (9:00:20), generate a first timing task t' corresponding to the next timing time according to the flow control rule, and repeat the above process until all timing tasks corresponding to the current flow scheduling are completed.
In other embodiments of the present application, besides generating and sending the timing tasks one by one, a plurality of timing tasks may be taken as one batch, so as to generate and send the timing tasks in batches. For example, three timing tasks t1, t2, t3 may be generated simultaneously at a time, and then when the preset time is reached, the following two operations are performed: firstly, sending timing tasks t1, t2 and t3 to a pressure applying device; and secondly, updating the timing tasks t1, t2 and t3 to be t1', t2' and t3' according to the flow control rule corresponding to the scheduling task. And then repeating the process until all timing tasks corresponding to the current flow scheduling are completed.
In addition, the embodiment of the application also provides a pressure test flow control method, which can provide a control interface for a user, and then acquire a pressure test task created by the user on the control interface and a plurality of input flow control rules related to the pressure test task.
The control interface can be used for a user to input a corresponding operation instruction so as to realize the creation of the stress test task and the input of relevant information about the stress test task.
For example, in an actual scenario, an input box for inputting a URL to be tested may be provided in the control interface, a task of performing a pressure test on the URL may be created by inputting the URL to be tested in the input box, an input area for inputting a flow control rule may be provided, a plurality of flow control rules may be input by a user in the input area, or a trigger button for directly searching for a preset flow control rule may be provided in the input area, so that the user may search for a preset default rule in a rule base without manually inputting the default rule by the user each time. It will be understood by those skilled in the art that the specific forms of the control interface described above are merely exemplary, and that other forms, whether now known or later developed based on similar principles, if applicable to the present application, are intended to be included within the scope of the present application and are hereby incorporated by reference.
The plurality of flow control rules can be used for generating a timing task, the timing task comprises flow information of timing time, the flow information can be provided for the pressure applying equipment to control the pressure applying equipment to output flow for pressure testing according to the flow information at the timing time, therefore, for a user, the pressure applying equipment can be controlled to simulate a complex scene with frequently changing flow according to the flow information only by inputting the plurality of flow control rules once when the pressure testing task is created so as to combine the timing task, and the pressure applying equipment can be controlled to conveniently realize the pressure testing according with the actual scene.
In an actual scenario, an execution subject of the pressure test flow control method may be a user equipment, or a device formed by integrating the user equipment and a network device through a network. The user equipment includes an input/output device for implementing interaction with a user, such as acquiring operation and instruction of the user, displaying an image, and the like. The part of the scheme related to data processing can be implemented locally in the user equipment, or can be implemented in the network equipment and provides the processing result to the user equipment through the network, and the part related to interaction is implemented only by the user equipment. The user equipment comprises but is not limited to various terminal equipment such as a computer, a mobile phone and a tablet computer; including but not limited to implementations such as a network host, a single network server, multiple sets of network servers, or a cloud-computing-based collection of computers. Here, the Cloud is made up of a large number of hosts or web servers based on Cloud Computing (Cloud Computing), which is a type of distributed Computing, one virtual computer consisting of a collection of loosely coupled computers.

The pressure test flow scheduling device provided by the embodiment of the application can acquire a plurality of flow control rules, then generates a timing task according to the flow control rules, and sends the timing task to the pressure applying device so as to enable the pressure applying device to output the flow for pressure test at the timing time according to the flow information.
In a practical scenario, the specific implementation of the apparatus may include, but is not limited to, implementations such as a network host, a single network server, multiple network server sets, or a cloud computing-based computer collection. Here, the Cloud is made up of a large number of hosts or web servers based on Cloud Computing (Cloud Computing), which is a type of distributed Computing, one virtual computer consisting of a collection of loosely coupled computers.
Fig. 7 shows a structure of a stress test traffic scheduling apparatus provided in an embodiment of the present application, where the apparatus includes a data obtaining module 710, a data processing module 720, and a data sending module 730. The data obtaining module 710 is configured to obtain a plurality of flow control rules; the data processing module 720 is configured to generate a timing task according to the plurality of flow control rules, where the timing task includes flow information of a timing time; the data sending module 730 is configured to send the timing task to the pressure applying device, so that the pressure applying device outputs a flow rate for pressure testing according to the flow rate information at a timing time.
The flow control rule contains relevant information for determining the flow rate of the pressure test performed by the pressure applying device at a specific time, for example, the flow control rule may be that the test flow rate is increased or decreased by a preset value at a specific time, or the flow rate is adjusted accordingly when the current flow rate satisfies what condition, etc.
The timing task can be provided for the pressure applying equipment, so that the pressure applying equipment is controlled to output the flow for pressure test at the timing time according to the flow information, and therefore for a user, only a plurality of flow control rules need to be input once when the pressure test task is created, so that the timing task is combined, the pressure applying equipment can be controlled to simulate a complex scene with frequently changed flow according to the flow information, and the pressure test conforming to an actual scene can be conveniently realized.
In some embodiments of the present application, the timing task generated by combining the plurality of flow control rules includes flow information of a timing time, the timing time being a time point determined based on the flow control rules at which an adjustment of the flow of the pressure test is required, and the flow information of the timing time being a flow value adjusted at the adjusted time point. For example, in the embodiment of the present application, a timing task t1 is to adjust the flow rate of the pressure test to 1000 at the time point of 16:30:20, so that the flow rate information of the included timing time is: 16:30:20, 1000, it is understood that the flow rate is set to 1000 at this point in time 16:30: 20.
In an actual scenario, the number of timing tasks that can be determined based on the flow control rule may be multiple, and thus the flow rate of the pressure test may be continuously adjusted for the timing time corresponding to the multiple timing tasks, so that a complex scenario in which the flow rate frequently changes is simulated. In some embodiments of the present application, each flow control rule includes at least first rule information for determining a timing time and second rule information for determining flow information.
The timing time required to adjust the flow may be determined by the first rule information, and may include, for example, a delay time, an interval time, an execution number, and the like, where the delay time refers to a time when the flow adjustment is first performed, the first timing time corresponding to the flow control rule may be determined, the interval time refers to an interval of each subsequent execution, the subsequent timing time corresponding to the flow control rule may be determined, the execution number refers to a number of times when the flow adjustment is performed based on the flow control rule, and the number of timing times corresponding to the flow control rule may be determined. In a specific case, if the execution is required to be always executed, the execution times can be set to be infinite. For example, if the first rule information of a certain flow control rule includes information of delay time, time interval, and execution times of 200s, 10s, and 100 times, respectively, it can be determined that after the first timing time of the timing task corresponding to the flow control rule is 200 seconds, each of the subsequent 10 seconds is a timing time, such as 210 seconds, 220 seconds … …, and the like, the total of 100 times is executed.
The flow value adjusted at each timing time may be determined by the second rule information, and may include, for example, an adjustment rule, an initial value, and the like. The adjustment rule is a calculation rule for adjusting the flow rate value at each timing time, and may be, for example, a rule related to time, a rule related to historical flow, or a binary dynamic parameter rule related to both time and historical flow. In practical scenarios, the adjustment rule may be expressed in a function expression related to time and/or historical flow, for example, 600+500 · sin (t/240 · 2 · pi) may represent a flow adjustment rule in a sine wave form related to time, last +50 may represent an adjustment rule in an incremental form related to historical flow (last adjusted flow value), and if (last > 50) the return 50 may represent an adjustment rule in a conditional decision form related to historical flow. The initial value may be used to set the flow value at the time of the first adjustment, and may be used in combination with a partial adjustment rule to complete the adjustment of the flow, for example, the initial value of the flow may be set to 50.
Therefore, the flow control rule comprises the first rule information and the second rule information, and the corresponding timing task can be analyzed.
Because the flow control rules are mutually independent, corresponding timing tasks can be determined, each timing task is used for correspondingly adjusting the flow in the corresponding timing time, and a complex flow change scene can be simulated after the timing tasks are combined, so that the pressure test conforming to the actual scene is realized.
In some embodiments of the present application, when obtaining a plurality of flow control rules, an original rule input by a user may be obtained first, and then an orchestration task set may be obtained by parsing according to the original rule. The arrangement task set comprises a plurality of arrangement tasks which are independent from each other, and each arrangement task comprises a corresponding flow control rule. For example, the original rule R provided by the user may be in the form of a character string, and after the device obtains the character string, the device may obtain an arrangement task set by parsing the character string, where each arrangement task in the arrangement task set has a respective attribute. These attributes may represent the first rule information and the second rule information, thereby constituting a flow control rule for each orchestration task. For example, in the present embodiment, the orchestration task set obtained by parsing the original rule may include orchestration tasks r1, r2, and r3, each of which includes the following attributes: latency, interval, scheduling rules, number of executions, whether to execute forever, whether to reset, initialization values, etc.
Taking r1 as an example, the delay time is 10s, the interval time is 10s, the execution times is 5, and whether the execution is always performed is no, the arrangement rule is: last +10, if reset is true, the initialization value is 20, where the delay time, interval time, execution times, and whether to execute the first rule information that can constitute the flow control rule forever, and the scheduling rule, whether to reset, and the initialization value constitute the second rule information in the flow control rule. And the delay time in the attribute of the scheduling task r2 is 60s, the interval time is 10s, the execution times is 5, and whether the execution is always negative is determined as follows: last-10, if the reset is no, the initialization value is null; the delay time of the attribute of the orchestration task r3 is 110s, the interval time is 10s, the execution times is 5, and whether the execution is always yes or not, the orchestration rule is: last + t/10, if the reset is no, the initialization value is null. Therefore, based on the arrangement task set obtained by analyzing the original rule R, a total of 15 timing tasks can be determined, and the timing time corresponding to the timing tasks is respectively 10s, 20s, 30s, … …, 140s and 150 s. After the timing task is sent to the pressure applying device, the pressure applying device can output the flow rate for the pressure test at the timing time according to the flow rate information, and fig. 2 is a schematic diagram of the flow rate for the pressure test in this embodiment.
In an actual scenario, different scheduling task sets can be obtained according to different original rules R, wherein flow control information included in the scheduling tasks is also different, so that various different flow change situations can be combined, for example, fig. 3 to 6 are schematic diagrams of flow change situations simulated by using the scheme provided by the embodiment of the present application to implement flow scheduling during pressure testing, so that flow change scenarios including periodicity, impulse and other high correlation with time series can be simulated.
In some embodiments of the present application, the scheduling device generates a timing task according to the plurality of flow control rules, and then sends the timing task to the pressure applying device, so that the pressure applying device outputs a flow for pressure testing according to the flow information at a timing time. In a practical scenario, the dispatching device may generate timing tasks one by one or batch by batch and send the timing tasks to the pressure applying device for execution, so that a short-time high load caused by generating all timing tasks at the same time may be avoided in a complex scenario. In this embodiment, the data processing module may determine whether there is a next timing time based on the current time, and when there is the next timing time, generate a first timing task corresponding to the next timing time according to the flow control rule, where the first timing task includes flow information of the next timing time. For example, taking the above-mentioned scheduling task set including scheduling tasks r1, r2, and r3 as an example, if the current time is the start time 9:00:00 of the current pressure test, it can be known that the next timing time is 9:00:10, and the flow value corresponding to the time is last + 10: 30, so that it can be determined that the first timing task t is to adjust the flow rate of the pressure test to 30 at 9:00: 10.
In this scenario, the data sending module of the scheduling device sends the first timing task to the pressure applying device after the next timing time of the first timing task is reached, so that the pressure applying device outputs a flow for pressure testing according to the flow information. After the scheduling device sends the first timing task to the pressure applying device, the pressure applying device may receive and process information included in the first timing task, and adjust the generated flow rate by the asynchronous pressure measurement engine at the next timing 9:00: 10. The scheduling device may continue to attempt to generate a new first timing task while sending the first timing task, that is, continue to determine whether a next timing time exists based on the current time (9:00:10), and when the next timing time exists (9:00:20), generate a first timing task t' corresponding to the next timing time according to the flow control rule, and repeat the above process until all timing tasks corresponding to the current flow scheduling are completed.
In other embodiments of the present application, besides generating and sending the timing tasks one by one, a plurality of timing tasks may be taken as one batch, so as to generate and send the timing tasks in batches. For example, three timing tasks t1, t2, t3 may be generated simultaneously at a time, and then when the preset time is reached, the following two operations are performed: firstly, sending timing tasks t1, t2 and t3 to a pressure applying device; and secondly, updating the timing tasks t1, t2 and t3 to be t1', t2' and t3' according to the flow control rule corresponding to the scheduling task. And then repeating the process until all timing tasks corresponding to the current flow scheduling are completed.
In addition, the embodiment of the application also provides a pressure test flow control device, which comprises an interaction module and a data acquisition module. The data acquisition module is used for providing a control interface for a user.

The data acquisition module is used for acquiring a pressure test task created by a user on the control interface and a plurality of flow control rules input by the user about the pressure test task.
The control interface can be used for a user to input a corresponding operation instruction so as to realize the creation of the stress test task and the input of relevant information about the stress test task.
For example, in an actual scenario, an input box for inputting a URL to be tested may be provided in the control interface, a task of performing a pressure test on the URL may be created by inputting the URL to be tested in the input box, an input area for inputting a flow control rule may be provided, a plurality of flow control rules may be input by a user in the input area, or a trigger button for directly searching for a preset flow control rule may be provided in the input area, so that the user may search for a preset default rule in a rule base without manually inputting the default rule by the user each time.
