Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of network communication, and in particular to a message processing method and device. BACKGROUND

[0002] The park controller supports device automatic configuration, and a user can realize device automatic online through a small amount of configuration. In the latest automatic configuration scheme of the controller, a WebSocket connection is established between a device and a Websocket component of an operation and maintenance platform to realize interaction, and the Websocket of the platform sends a message to the controller when establishing the connection.

[0003] The message of the device establishing the connection is first put into a message queue in the controller, and a specific process consumes the message. At this time, a problem is generated: when the speed of producing the message is much greater than the speed of consumption, the message in the message queue cannot be consumed in time, and the subsequent message is blocked in the queue. The newly accessed device cannot be normally online on the controller.

[0004] At present, when an exception occurs in the environment, common exception conditions are address conflicts caused by the same IP of the device (for example, brain split of stacked devices), and the WebSocket connection established by the device is repeatedly disconnected and reconnected. A specific example is that the IP of device A is the same as that of device B, so that the two devices can simultaneously establish a WebSocket connection. However, the TCP connection of the same IP can only maintain one, and when the A device establishes the connection, the B device is disconnected; when the B device establishes the connection, the A device is disconnected. The WebSocket component notifies the controller of all the messages, and the messages in different conditions only contain the IP, sequence number and other basic information of the device, and cannot distinguish the message in which condition the message is sent. The controller is the last end of the message transmission and cannot interfere with the processing flow of the WebSocket. The controller can only passively accept and process all the messages, and a large amount of messages leads to the occupation of threads, so that the new device cannot be online.

[0005] Therefore, how the controller improves the message processing efficiency becomes a problem to be solved at present. SUMMARY

[0046] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "an" and "the" used in the present application and claims are intended to include plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein means any or all possible combinations of one or more associated listed items.

[0047] It should be understood that, although the embodiments herein can employ the terms first, second, third, etc. to describe various information, the information should not be limited to these terms. These terms are only used to distinguish one piece of information from another piece of information of the same type. For example, without departing from the scope of the present application, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information. Depending on the context, in addition, the word "if" used can be interpreted as "when" or "upon" or "in response to determining".

[0048] For example, refer to Figure 1 As shown in the detailed flowchart of a message processing method provided by the embodiments of the present application, the method is applied to a controller, and the method comprises the following steps:

[0049] Step 100: parsing the online message of a target device to obtain the target IP and the target device serial number of the target device.

[0050] In actual application, after the device to be online establishes a websocket connection with the websocket component of the operation and maintenance platform, the websocket component sends the message (online message) of establishing the connection with the device to the controller through the message middleware. Specifically, the controller can put the received online message into the message queue, and then a specific process consumes the message in the message queue.

[0051] Then, when the controller consumes the message in the message queue, the online message of the target device to be processed is obtained from the message queue, and then the online message of the target device is parsed to obtain the IP address and the device serial number of the target device.

[0052] Step 110: judging whether the local maintains an associated record of the IP and the device serial number matched with the target IP.

[0053] In the embodiments of the present application, if it is determined that the local does not maintain an associated record of the IP and the device serial number matched with the target IP, an associated record of the target IP and the target device serial number is recorded locally, and the device count corresponding to the target IP is increased by 1.

[0054] The device count corresponding to an IP refers to the number of devices using the IP to send online messages.

[0055] Specifically, the associated relationship of each device that has sent an online message and the IP address used by the device is added. When an IP address is used by a device for the first time, the device is connected with the websocket component for device online, and the controller parses the online message to maintain the associated relationship of the IP address and the device serial number of the device in the local.

[0056] In this way, when processing a subsequent online message, the controller first determines whether the IP carried by the online message is recorded locally. If not, the controller directly processes the online message and records / maintains the association between the IP and the device serial number of the corresponding device locally.

[0057] Step 120: If it is determined that the local maintenance has the association record of the IP and the device serial number matching the target IP, it is determined whether the target device serial number is consistent with the device serial number included in the association record.

[0058] Specifically, if the controller determines that the local maintenance has the association between the IP address corresponding to the target IP and the device serial number, it means that the device has sent an online message using the target IP. Therefore, it is further determined whether the target device serial number of the target device is consistent with the device serial number included in the association record.

[0059] Step 130: If it is determined that the target device serial number is not consistent with the device serial number included in the association record, the online message of the target device is discarded.

[0060] That is, if the controller determines that the target device serial number is not consistent with the device serial number included in the association record, it means that there may be an IP address conflict, i.e., different devices use the same IP address for online operation. Since the target IP address has been used for online operation by other devices, the online message is directly discarded and not processed. Further, the controller increments the device count corresponding to the target IP by 1. Obviously, the device count corresponding to the target IP is greater than or equal to 2 at this time.

[0061] In the embodiment of the application, if it is determined that the target device serial number is consistent with the device serial number included in the association record, it is determined whether the online message processing number corresponding to the IP is greater than a set threshold. If yes, the online message of the target device is discarded. Otherwise, the online message of the target device is processed and the online message processing number corresponding to the target IP is incremented by 1.

[0062] That is, the target device sends an online message to the controller using the target IP multiple times, and the controller has processed the online message sent by the target device. The controller records the online message processing number corresponding to the target IP and the target device to be incremented by 1 each time the target device uses the target IP to send an online message. Of course, in the embodiment of the application, when processing the first online message of the target device using the target IP, the online message processing number corresponding to the target IP can not be incremented, or the online message processing number corresponding to the target IP can be incremented. In this embodiment, it is not specifically limited.

[0063] In this way, whether a device (network concussion) repeatedly sends a large number of online messages is detected, if yes, only a specified number of online messages are processed, and subsequent online messages are not processed, so as to avoid that the device frequently sends online messages and occupies controller resources.

[0064] Further, in the embodiment of the application, when an online message is parsed, the timestamp information of parsing the online message can be recorded, for example, {target IP, target device serial number, timestamp} is recorded locally, of course, only the timestamp of the last time of parsing the online message corresponding to the target IP and the target device serial number can be recorded, for example, it is assumed that {target IP, target device serial number, timestamp 1} has been recorded for the target IP and the target device serial number, if an online message with the target IP and the target device serial number is parsed again, {target IP, target device serial number, timestamp 1} is replaced with {target IP, target device serial number, timestamp 2}.

[0065] Then, the message processing method described above can further include the following steps in the embodiment of the application:

[0066] Based on the preset period, whether the device count corresponding to each IP is 1 is determined, if the device count corresponding to an IP is 1, and the difference between the timestamp of the last time of parsing the online message of the device and the current time is greater than a preset threshold, the association record and the count information corresponding to the IP are deleted;

[0067] If the device count corresponding to an IP is greater than 1, whether the difference between the timestamp of the last time of parsing the online message of each device and the current time is greater than a preset threshold is determined, if the number of devices whose difference is less than the set threshold is less than or equal to 1, the association record and the count information corresponding to the IP are deleted.

[0068] For example, the preset period is 3 minutes / 5 minutes (for example, 3 minutes, which can be customized based on user demand / application scenario), then, the traversal can be performed every 3 minutes, whether the device count corresponding to each IP is 1 is determined, if the device count corresponding to an IP is 1, it is determined that only one device of the IP is used to log in, and whether the difference between the timestamp of the last time of parsing the online message of the IP and the device and the current time is greater than 5 minutes is further determined, if yes, it is indicated that the device using the IP has not sent an online message in the past 3 minutes, the association relationship between the IP address and the device serial number of the device and the count information (the count of parsing the online message, the device count of the IP) of the device corresponding to the IP can be deleted, in this way, if the device is replaced by other devices due to failure, and the IP is still used to log in normally.

[0069] If the device count corresponding to an IP address is not 1, it indicates that multiple devices (e.g., device 1 and device 2) have used that IP address to go online. In this case, it's necessary to determine if the difference between the timestamp of the last online message parsed for each device using that IP address and the current time is greater than 5 minutes. If the difference is greater than 5 minutes for both device 1 and device 2, the association and count information corresponding to that IP address can be deleted. If the difference is less than 5 minutes for only one device, the association and count information corresponding to that IP address can also be deleted. If the difference is less than 5 minutes for both devices, it means that the two devices may still be competing for the WebSocket connection and will still send online messages to the controller; in this case, the association and count information corresponding to that IP address will not be deleted for the time being.

[0070] In this embodiment, the online message is processed in segments using asynchronous processing.

[0071] Specifically, the online message processing process is divided into a first stage of obtaining basic device information and a second stage of sending configuration to the device; the steps for processing the online message of the target device include:

[0072] Start the first thread to obtain the basic device information of the target device, and release the first thread after the execution is completed.

[0073] Start a second thread to determine if there is a record of the second phase of the target device being executed locally. If there is, discard the online message of the target device and release the second thread; otherwise, interact with the target device, execute the configuration distribution operation, and release the second thread after confirming that the execution is complete, and record the record of the second phase of the target device being executed.

[0074] This is to avoid repeatedly sending configurations to the same device, which would consume threads and improve message processing efficiency.

[0075] Furthermore, in this embodiment, a corresponding thread lock is configured for each device. When a thread is already processing an online message for a device, it occupies the thread lock of that device so that other threads cannot process other online messages for that device, thereby avoiding the situation where several devices send a large number of duplicate online messages and occupy all threads.

[0076] For example, see Figure 2 The diagram shown is a structural schematic of a message processing device provided in an embodiment of this application. This device is applied to a controller and includes:

The steps for processing the online message of the target device include: Start the first thread to obtain the basic device information of the target device, and release the first thread after the execution is completed; Start a second thread to determine if there is a record of the second phase of the target device being executed locally. If there is, discard the online message of the target device and release the second thread; otherwise, interact with the target device, execute the configuration distribution operation, and release the second thread after confirming that the execution is complete, and record the record of the second phase of the target device being executed.

6. A message processing device, characterized in that, Applied to a controller, the device includes: The parsing unit is used to parse the online message of the target device to obtain the target IP and the target device serial number. The judgment unit is used to determine whether there is an association record of IP and device serial number that matches the target IP maintained locally; If the determination unit determines that there is an association record of IP and device serial number that matches the target IP in the local maintenance, the determination unit is further used to determine whether the target device serial number is consistent with the device serial number included in the association record; If the judgment unit determines that the target device serial number is inconsistent with the device serial number included in the associated record, the processing unit is used to discard the online message of the target device.

7. The apparatus as claimed in claim 6, characterized in that, The device further includes: If the judgment unit determines that there is no associated record of IP and device serial number matching the target IP maintained locally, the recording unit is used to record the associated record of the target IP and target device serial number locally and increment the device count corresponding to the target IP by 1.

8. The apparatus as claimed in claim 7, characterized in that, If the judgment unit determines that the target device serial number is inconsistent with the device serial number included in the associated record, the judgment unit is further configured to determine whether the number of online message processing times corresponding to the IP is greater than a set threshold. If so, the processing unit is configured to discard the online message of the target device; otherwise, the processing unit is configured to process the online message of the target device and increment the number of online message processing times corresponding to the target IP by 1.

9. A message processing device, characterized in that, The message processing device includes: Memory, used to store program instructions; A processor is configured to invoke program instructions stored in the memory and execute the steps of the method as described in any one of claims 1-5 according to the obtained program instructions.

10. A computer-readable storage medium, characterized in that, The computer-readable storage medium stores computer-executable instructions for causing the computer to perform the steps of the method as described in any one of claims 1-5.
