Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
Aiming at the problem that the management platform issues commands to a large number of terminals at the same time, the problem that the surge phenomenon is likely to occur, the load of the server is too large, the server is even collapsed, and the overall management and control efficiency is reduced is solved.
The terminal control method of the present disclosure is described below in conjunction with some embodiments of the present disclosure.
Fig. 1 is a flow chart of some embodiments of a terminal control method of the present disclosure. As shown in fig. 1, the method of this embodiment includes: steps S102 to S106.
And step S102, responding to the establishment of batch tasks for the plurality of terminals, and starting a heartbeat counting function for the plurality of terminals.
An administrator or a management system can establish batch tasks for a plurality of terminals according to actual requirements, and the tasks corresponding to the terminals can be stored in a database. The method can firstly judge whether the number of the terminals needing to execute the task reaches the threshold value of the gray control, and if the number of the terminals reaches the threshold value of the gray control, the heartbeat counting function is started for each terminal.
A heartbeat counting module may be provided in the terminal control device (management platform) for performing heartbeat counting for each terminal. Can set up heartbeat counting function respectively to each terminal in the heartbeat counting module, heartbeat counting function includes: the terminal comprises a terminal identification, a heartbeat counting starting zone bit, a heartbeat counter and a heartbeat threshold value. The identifier of the terminal is, for example, a Media Access Control (MAC) address of the terminal. Since each terminal is not necessarily capable of sending heartbeat packets on time (e.g., a terminal failure), it is more accurate to set a heartbeat counter for each terminal separately.
For a terminal with a heartbeat counting function established, the heartbeat counting function is directly started, for example, the position of the heartbeat counting start flag is set to 1. For the terminal without the heartbeat counting function, marking as the terminal to be started, when receiving the heartbeat packet of the terminal, inquiring the terminal marked as the terminal to be started according to the identification of the terminal in the heartbeat packet, establishing and starting the heartbeat counting function for the terminal,
and step S104, respectively carrying out heartbeat counting on the plurality of terminals according to the received heartbeat packets of the plurality of terminals by using a heartbeat counting function.
In some embodiments, a corresponding heartbeat counting function is searched according to a terminal identifier carried in a received heartbeat packet, and under the condition that the heartbeat counting function is established for the terminal and started, a heartbeat counter corresponding to the terminal is incremented by one according to the terminal identifier; and under the condition that the heartbeat counting function is not established for the terminal, establishing the heartbeat counting function for the terminal, starting the heartbeat counting function, and adding one to a heartbeat counter corresponding to the terminal.
And step S106, under the condition that the heartbeat count of the terminal reaches the corresponding heartbeat threshold value, issuing a corresponding task to the terminal.
In some embodiments, a task query instruction is sent to the database according to the identifier of the terminal, a task of the terminal returned by the database is received, and the task is issued to the terminal. The database stores tasks to be issued corresponding to the terminals, one terminal may correspond to a plurality of tasks, and the plurality of tasks correspond to different execution sequences. The condition that the heartbeat count reaches the heartbeat threshold value triggers a terminal control device (a management platform) to inquire the behavior of the terminal task to the database, and further the task can be issued to the terminal according to the sequence of the terminal task in the database.
The plurality of terminals may be partitioned into at least one set of heartbeat thresholds, with different sets of heartbeat thresholds corresponding to different heartbeat thresholds. The terminal control device (management platform) can display a management and control interface to an administrator, information of each terminal, such as task content, terminal model, geographic position and the like, is displayed in the management and control interface, the administrator divides the terminals according to actual requirements, and different heartbeat threshold values are set for each heartbeat threshold value set. For example, the administrator may divide the terminals into different heartbeat threshold value sets according to the geographical locations, set a lower heartbeat threshold value for the terminals in the beijing area, and preferentially trigger the task issuing.
The terminal control device (management platform) can also be internally provided with a division rule of the terminal in advance, automatically divide different heartbeat threshold value groups for the terminal according to the information of each terminal according to the division rule, and set different heartbeat threshold values. Some embodiments are described below.
In some embodiments, the number of terminals which can be loaded by the current service end is determined according to the load condition of the service end when the historical terminals execute the tasks, the load condition of the current service end and the type of the current batch tasks; and dividing the terminals of the task to be issued corresponding to the server into different heartbeat threshold value groups according to the number of the terminals which can be loaded by the current server and the number of the terminals of the task to be issued corresponding to the server.
Different terminals may correspond to different tasks to be executed, and different tasks may correspond to different servers. For example, some terminals need to upgrade firmware, and some terminals need to modify configuration parameters, which correspond to different servers respectively.
The terminal control device (management platform) can acquire historical load conditions of each server when the terminal executes tasks. The terminal control device (management platform) can determine the corresponding service end according to the type of the current batch task, and determine the number of terminals which can be loaded by the current corresponding service end according to the resource amount occupied by the historical terminals when the tasks of the type are executed, and the residual resource amount of the current corresponding service end. Further, the number of the terminal to which the task is to be issued is divided by the number of the terminal which can be loaded at the corresponding server to obtain the number of the heartbeat threshold value groups divided by the terminal, and the number of the terminals in each heartbeat threshold value group is obtained. And if the quotient is a non-integer, rounding up.
If the terminals to be executed correspond to a plurality of different service terminals respectively, after the terminals are divided into different heartbeat threshold value sets for each service terminal, the number of the terminals in the same heartbeat threshold value set of each service terminal can be combined, and the number of the terminals in each heartbeat threshold value set is determined.
When the number of terminals that can be loaded by the server is determined, if the server corresponds to multiple tasks of the terminal, the load condition when multiple terminals simultaneously and respectively execute multiple tasks needs to be considered when the load of the server is considered. For example, a terminal needs to occupy resources of a certain service end for upgrading firmware and modifying configuration parameters, and a task to be issued currently includes upgrading firmware and modifying configuration parameters, so that when the historical load condition of the service end is referred, the resource amount occupied by multiple terminals when executing two tasks of upgrading firmware and modifying configuration parameters respectively at the same time needs to be referred, and the number of terminals which can be loaded by the service end is further determined.
In some embodiments, different servers arranged in the terminal control device (management platform) may correspond to different tasks. According to the method, different heartbeat threshold value groups are divided for the terminals according to the whole resource occupation condition of the terminal control device (management platform) when the historical terminals execute the same task and the historical whole resource occupation condition, the resource use condition of the current terminal control device (management platform) and the number of the terminals of the task to be issued.
The foregoing embodiments may be used in combination with each other, that is, the heartbeat threshold value set of the terminal is determined by referring to the load condition of each server and also referring to the overall load condition of the terminal control device (management platform).
Under the condition that the historical load condition or the current load condition is inconvenient to estimate, the balance between the load of the server and the task issuing rate of the terminal can be gradually achieved by adopting a mode of gradually increasing the number of the terminals of each heartbeat threshold value set. Specific implementations can be found in the following examples.
In some embodiments, a preset number of terminals are selected as the terminals of the heartbeat threshold value set with the lowest heartbeat threshold value; selecting terminals of the next heartbeat threshold value set within a preset heartbeat interval after the terminals of the current heartbeat threshold value set reach a heartbeat threshold value, and setting the heartbeat interval as a difference value of heartbeat threshold values between preset terminals of all heartbeat threshold value sets until the terminals are completely divided; the method comprises the steps that when a terminal of a current heartbeat threshold value set executes a task, corresponding server load does not reach a preset load threshold value, the number of terminals of a next heartbeat threshold value set is equal to the sum of the number of terminals of a previous heartbeat threshold value set and a preset addition value, and when the corresponding server load reaches the preset load threshold value when the terminal of the current heartbeat threshold value set executes the task, the number of terminals of the next heartbeat threshold value set is equal to the number of terminals of the previous heartbeat threshold value set.
For example, the terminal of the heartbeat threshold value group with the lowest heartbeat threshold value is set to be 1000 first, the preset heartbeat interval is 5 heartbeats, and the preset increment value is 500. And when 5 heartbeats of the heartbeat threshold values of the first heartbeat threshold value set with the lowest heartbeat threshold value are reached, issuing a task to the terminal of the first heartbeat threshold value set, and monitoring the load of the server corresponding to the terminal of the first heartbeat threshold value set in the following 5 heartbeats. And if the preset load threshold value is not reached, setting the number of the terminals in the second heartbeat threshold value group to be 1500, correspondingly setting the heartbeat threshold value corresponding to the terminals in the second heartbeat threshold value group to be 10 heartbeats, and repeating the steps to monitor the load of the service end when the terminals in each heartbeat threshold value group execute the task, and if the preset load threshold value is reached, not increasing the number of the terminals in the subsequent heartbeat threshold value groups.
The method of the embodiment can also be used as an evaluation of the load capacity of the server in the test stage, and when the method is actually used, the number of terminals when the server reaches the preset load threshold value, the load condition of the current server and the number of terminals of the task to be issued are divided into different heartbeat threshold value groups.
The method of each embodiment is mainly used for determining the number of the terminals in each heartbeat threshold value group, the terminals in each heartbeat threshold value group can be randomly selected, or the terminals in each heartbeat threshold value group can be determined by referring to various information (such as regions, manufacturers, equipment models and user information) of the terminals, and the heartbeat threshold value group of the terminals is determined, that is, the sequence of tasks issued to the terminals is determined, that is, the height of the heartbeat threshold value of the terminals is determined. Some embodiments are described below.
In some embodiments, the heartbeat threshold of each terminal is determined according to the priority of the task corresponding to each terminal, and the higher the priority of the corresponding task is, the lower the heartbeat threshold of the terminal is. The priority of the task can be set according to actual requirements, such as the emergency degree of the task, the priority of a user corresponding to the task, and the like.
Optionally, the terminal is first divided into different task groups, and each task group is sorted according to the priority of the tasks. Starting from the task group with the highest priority, the terminals in the task group can be divided into different heartbeat threshold value groups by using the method in the foregoing embodiment, and the tasks issued to the terminals in the task group are completed according to the heartbeat threshold value of each heartbeat threshold value group (i.e., steps S102 to S104). After the terminal tasks in one task group are completely issued, the working process of the next task group is entered, and the task issuing process is executed for the terminals in each task group in sequence. The heartbeat threshold of the terminal in the task group in the front is lower than that of the terminal in the task group in the back, that is, the heartbeat threshold of the terminal with the higher task priority is lower.
The task group division can be performed according to the actual requirements according to the information of various terminals such as regions, manufacturers, equipment models, user information and the like besides the priority of the tasks, and the sequence of each task group can also be determined according to the actual requirements by referring to the information of various terminals.
Optionally, when multiple tasks to be issued can be processed simultaneously, a terminal with a high task priority is preferably selected as much as possible in the heartbeat threshold value set with a low heartbeat threshold value according to the load capacity of the server corresponding to the tasks. For example, the first heartbeat threshold value group is the heartbeat threshold value group with the lowest heartbeat threshold value, the number of terminals in each heartbeat threshold value group is 1000, and assuming that the server can process two tasks with different priorities, under the condition that the load of the server allows, terminals with high priorities of corresponding tasks are preferentially selected from the first heartbeat threshold value group and the previous heartbeat threshold value groups.
Optionally, the intervals of the heartbeat threshold values of different heartbeat threshold value sets are adjusted according to the priority of the task. For example, task priority is high and the interval of heartbeat thresholds from different sets of heartbeat thresholds is short.
In the method of the embodiment, the terminals of the task to be issued are divided into at least one heartbeat threshold value group, different heartbeat threshold value groups correspond to different heartbeat threshold values, each terminal is subjected to heartbeat counting according to the heartbeat packet of each terminal, and the corresponding task is issued to the terminal when the counting reaches the heartbeat threshold value. The method of the embodiment can realize gray control of a large number of terminals based on a heartbeat mechanism, greatly reduce the occurrence probability of a tidal surge phenomenon, reduce the load pressure of a server side, and improve the overall management and control efficiency. In addition, the method of the embodiment does not affect the running of the historical batch tasks when the batch tasks are issued to the terminal, and further improves the overall management and control effect compared with a scheme of continuously closing the historical batch tasks to avoid overlarge load of the server.
According to the condition of the heartbeat packet of the receiving terminal, whether the terminal is on line or not can be judged, and the heartbeat threshold value of the terminal which is not on line for a long time can be adjusted. In some embodiments, in the case that the terminal is not online, counting the time that the terminal is not online; and when the offline time of the terminal reaches a time threshold, reducing the heartbeat threshold of the terminal according to a preset step length.
For example, if the original heartbeat threshold of a terminal is 10 heartbeats, but the terminal is not online for three consecutive days, the heartbeat threshold is reset to 3. Because the device is not on-line again for a long time, the on-line behavior is usually random and no surge generally occurs.
According to the method, the heartbeat mechanism is adopted to issue the tasks to the terminal, the offline state of the terminal can be found, the polling process of the terminal is reduced, signaling resources are saved, and the overall management and control efficiency is improved.
Further embodiments of the terminal control method of the present disclosure are described below with reference to fig. 2.
Fig. 2 is a flow chart of some embodiments of a terminal control method of the present disclosure. As shown in fig. 2, the method of this embodiment includes: steps S202 to S220.
Step S202, responding to the establishment of batch tasks for the terminal, and starting a heartbeat counting function for the terminal.
There are a plurality of terminals for establishing the batch tasks, and steps S202 to S220 are steps that need to be executed for each terminal to which a task is to be issued.
And step S204, carrying out heartbeat counting on the terminal according to the received heartbeat packet of the terminal by using the heartbeat counting function.
The plurality of terminals are divided into at least one set of heartbeat thresholds, with different sets of heartbeat thresholds corresponding to different heartbeat thresholds.
And step S206, judging whether the heartbeat count of the terminal reaches a corresponding heartbeat threshold value, if so, executing step S208, otherwise, repeating step S204 and executing repeatedly.
And step S208, sending a task query instruction to the database according to the identifier of the terminal.
And step S210, receiving a task query result returned by the database, and issuing a corresponding task to the terminal.
Step S212, judging whether the task is successfully issued, if so, executing step S214, otherwise, executing step S216.
And step S214, closing the heartbeat counting function of the terminal.
Step S216, determine whether the number of failed delivery times reaches a threshold value. If so, step S218 is performed, otherwise, step S220 is performed.
Step S218, the reason of the delivery failure is judged, and the heartbeat counting function is determined to be closed or reset according to the failure reason.
For example, when the terminal is abnormal (for example, a failure code is returned), the abnormal condition of the terminal is recorded, and the heartbeat counting function is turned off to wait for the subsequent processing. And under the condition that the terminal is not on line (off line in the heartbeat counting process) or has no response, resetting the heartbeat counter of the terminal to be 0, restarting counting, and when waiting for reaching the heartbeat threshold value next time, issuing the task failed to be issued to the terminal again, or modifying the heartbeat threshold value of the terminal which is not on line or has no response according to actual requirements, for example, reducing the heartbeat threshold value.
And step S220, the task is issued again. The process returns to step S212 to resume the execution.
