Meanwhile, it should be noted that version numbers of the same application running in different node devices may be different, and applications running in different node devices may also be different.
The following is a detailed description of examples of the present application.
Example one
Fig. 2 is a schematic flowchart of a remote control method according to an embodiment of the present application, where the method is applied to the hierarchical system shown in fig. 1, and as shown in fig. 2, the method includes the following steps:
Specifically, as shown in fig. 1, when a user wants to update or rollback a certain application on a certain node device, the node device may be regarded as a target node device, the application may be regarded as a target application, and a control operation is performed on a master device, for example: the main device may display all the node devices, the user may select a target node device to be operated, at this time, each application running on the target node device is displayed on the main device, the user selects the target application again, then selects whether to perform an update operation or a rollback operation on the target application, and determines a version after the update or the rollback operation on the target application, at this time, the main device may determine whether to perform the update operation or the rollback operation on the control instruction of the target node device, a device identifier of the target node device, and a target version number of the target application according to the above operations, and may determine a path from the main device to the target node device according to a structure of the hierarchical system, so as to use the path as a node path of the target node device.
It should be noted that the update referred to in the present application is to update an application program from an application with a lower version number to an application with a higher version number, and the rollback is to update an application program from an application with a higher version number to an application with a lower version number.
Specifically, heartbeat information is sent between the master device and the subordinate node devices belonging to the master device, and between the superior node device and the subordinate node devices according to a set heartbeat cycle, so as to determine whether the master device and each node device still survive, that is: the main device sends heartbeat information to subordinate node devices belonging to the main device, the subordinate node devices also send heartbeat information to the main device, the superior node devices send heartbeat information to the subordinate node devices belonging to the superior node devices, the subordinate node devices also send heartbeat information to the superior node devices, and further the heartbeat information is sent mutually.
Since the heartbeat information is sent according to a period, the control information can be encapsulated in the heartbeat information to be sent in the current heartbeat period, so that the heartbeat information is sent to the subordinate node device belonging to the main device, and the subordinate node device can send the control information to the subordinate node device belonging to the subordinate node device after receiving the heartbeat information until the target node device is found.
And 203, for each level of node equipment, after the node equipment receives the heartbeat information, analyzing the received heartbeat information.
Specifically, for each node device, the node device may parse the heartbeat information after receiving the heartbeat information, and if the heartbeat information is obtained through parsing and the node device is not a target node device, after receiving the control information, the node device needs to encapsulate the control information in the heartbeat information sent to a lower node device, but not in the heartbeat information sent to a higher node device, so that the control information may be continuously transmitted in a direction away from the main device until reaching the target node device.
Since the higher node device can control the lower node devices, the higher node device knows all the lower node devices belonging to the higher node device, and therefore after one node device analyzes the heartbeat information to obtain the control information, it needs to judge whether the higher node device is the higher node device of the target node device according to the device identifier in the control information, if so, the control information needs to be carried in the heartbeat information sent to the target node device, but not in the heartbeat information sent to other lower node devices, as shown in fig. 1, if the node device B is the target node device, after the node device a receives the control information, the node device a only carries the control information in the heartbeat information sent to the node device B, and does not carry the control information in the heartbeat information sent to the node device C and the node device D.
If the node device receiving the control information is not the upper node device of the target node device, it indicates that the node device receiving the control information may be located on the node path, and therefore, it may be determined whether the node device itself is located on the node path according to the node path, and if the node device is located on the node path, the node device only needs to encapsulate the control information into the heartbeat information sent to all the node devices belonging thereto, so that it may be ensured that the control information is still sent toward the target node device, and if not, it indicates that it is impossible to send the control information to the target node device through the node device, and therefore, it is necessary to delete the control information, as shown in fig. 1, if the node device B is located in the hierarchical subsequent node device, after the node device a analyzes the obtained control information, if the node device B, the node device C, and the node device D are not target node devices, the control information is carried in the heartbeat information sent to the node device B, the node device C, and the node device D, if the node device B is located on the node path, the node device C and the node device D are not located on the node path, and if the target node device B carries the control information, it is not a target node device, it determines that the target node device that the control information is sent to the target node B, and if the target node device D, it only sends the target node device that the control information carried in the target node device is not carried in the control information, and if it is sent to the target node device, and if it is not carried in the target node device, and if it, and the target node device.
According to the method, the node devices positioned on the node path in each level of node devices can be screened, then the screened node devices send the control information to the lower level node devices, and the like until the control information is sent to the target node device.
In a feasible embodiment, fig. 3 is a schematic flowchart of another remote control method provided in an embodiment of the present application, and as shown in fig. 3, after receiving the second heartbeat information, the target node device performs specified control on the target application according to the target version number and the control instruction carried in the heartbeat information, which specifically may be implemented by the following steps:
And 304, if the version number of the target application currently operated by the adjacent node device is the same as the target version number, encapsulating the target application by the adjacent node device.
And 305, the adjacent node device sends the encapsulated target application to the target node device in a data stream form according to the query path.
And step 306, the target node device performs specified control on the currently running target application according to the encapsulated target application.
Specifically, because versions of target applications running in different node devices are different, the target node device may update or rollback the target application running by using the target application in the node device running the target version number, in order to determine which version number of the target application running in the node device is the target version number, the target node device may encapsulate the target version number into all heartbeat information to be sent, so as to send the heartbeat information to all neighboring node devices capable of performing heartbeat interaction with the target node device, for each neighboring node device adjacent to the target node device (including a higher node device of the target node device and each lower node device belonging to the target node device), the neighboring node device queries whether the version number of the target application running by itself is the same as the target version number after receiving the heartbeat information carrying the target version number, and if so, the neighboring node device encapsulates the target application, and then sends the encapsulated target application to the target node device in a data stream form, so that the target node device updates or rolls back the target application running by using a new query path after receiving the encapsulated target application. If the version number of the target application running in the adjacent node device adjacent to the target node device is not the target version number, for each adjacent node device, the adjacent node device packages the target version number into heartbeat information, then sends the heartbeat information to the adjacent node device adjacent to the adjacent node device, and so on until the version number of the target application running in a certain node device is the target version number, then the node device packages the target application running by itself, and then sends the heartbeat information to the target node device in a data stream mode, at this time, the node device does not send the heartbeat information carrying the target version number to the adjacent node device adjacent to the node device, only sends common heartbeat information to the adjacent node device adjacent to the node device, and when other node devices determine that the version number of the target application running by itself is not the target version number, the node device adjacent to the node device continues to send the heartbeat information carrying the target version number.
When a certain node device determines that the version number of the target application running by the certain node device is not the target version number, a query path is formed according to the node devices through which the version query instruction received by the node device passes, and the node path from the node device to the target node device can be determined through the query path, so that the target node device can be found. In the process of searching for the target version number, a plurality of query paths may be formed, where for each query path, the starting location is the target node device, and the end location includes two types: the first is the node device with the running target application version number as the target version number, and the second is the node device with the running target application version number not as the target version number, but the node device no longer has the adjacent node device adjacent to the node device, for the query path corresponding to the first condition, the node device with the running target application version number as the target version number stops continuously querying downwards, and the node devices with the running target application version numbers as the target version numbers in the hierarchical system can be traversed by the mode.
It should be noted that, the neighboring node devices in this application are not mutual, that is: the node device receiving the heartbeat information carrying the version inquiry command is a node device adjacent to the node device sending the heartbeat information, but the node device sending the heartbeat information is not the node device adjacent to the node device receiving the heartbeat information.
By the method, the target application in the target node equipment can be updated or rolled back by using the applications in the surrounding node equipment, so that the data volume in the heartbeat information is reduced, and the remote control efficiency of the target node equipment is improved.
In a possible embodiment, fig. 4 is a schematic flowchart of another remote control method provided in an embodiment of the present application, and as shown in fig. 4, after step 303 is executed, if a version number of the target application currently run by the neighboring node device is different from the target version number, the execution continues according to the following steps:
Specifically, for a certain version query instruction, in the process that the version query instruction is carried in heartbeat information and sent to an adjacent node device, a node device, that is, a query path, through which the version query instruction has passed is also recorded, the node device that has currently received the heartbeat information can determine the node device that has passed from a target node device to the node device according to the query path, and when the version number of a target application running in the node device is not a target version number, the query path is updated according to the position of the node device, a node path from the node device to the target node device can be obtained through the new query path, and then the new node path is sent to the adjacent node device of the node device through heartbeat information.
In a feasible embodiment, because a plurality of node devices running the target version number can be found by the method, and each node device sends the encapsulated target application to the target node device, in order to prevent the target node device from repeatedly updating or rolling back, the target node device deletes the subsequently received encapsulated target application after receiving the encapsulated target application for the first time, and the method can prevent the grading system from performing additional management on heartbeat information, thereby being beneficial to reducing the complexity of the analysis system.
In a possible embodiment, after the target node device completes the designated control, the target node device stores the designated control, the device identifier of the node device that sends the encapsulated target application, the version number before the designated control, and the version number after the designated control in the form of a key-value pair. Through the information, an update or rollback log of the target node device can be formed so as to facilitate subsequent inquiry.
