In this embodiment, an apparatus upgrading method is provided, and fig. 4 is a first flowchart of the apparatus upgrading method according to the embodiment of the present invention, as shown in fig. 4, the flowchart includes the following steps:
step S402, under the condition of receiving an upgrading instruction, acquiring a first number of target devices connected with a target platform and a second number of first devices to be upgraded;
step S404, determining a third number of proxy devices in the first device based on the first number and the second number;
step S406, dividing a data packet for upgrading the first device into at least two target data packets;
step S408, dividing at least two target data packets into a third number of data packet groups, and correspondingly sending the third number of data packet groups to the third number of proxy devices, so as to instruct the proxy devices to store the received data packet groups, and sending the received data packet groups to other first devices connected to the proxy devices, so that the first devices execute an upgrade operation based on the data packets after receiving all target data packets included in the data packets, where each proxy device receives one data packet group, and the data packet groups received by different proxy devices are different.
In the above embodiment, the upgrade instruction may be a device upgrade instruction triggered by a user, and the target platform may be a cloud upgrade platform, for example, a cloud server platform. One target platform can be connected with a plurality of devices, and under the condition that an upgrading instruction is received, a first number of target devices connected with the target platform and a second number of devices to be upgraded are obtained. The target device may be a device connected to the cloud platform and in an upgrade state, and/or a device which does not need to be upgraded, and the first device may be a device to be upgraded, and after determining the number of the target device and the number of the devices to be upgraded, the number of the agent devices is determined according to the two numbers. That is, the agent device may be assigned to the first device to be upgraded according to the processing capability of the target platform.
In the above embodiment, the data packet for upgrading the first device may be divided into at least two target data packets, and then the at least two data packets may be divided into a plurality of data packet groups. Wherein the number of packet groups may be the same as the number of proxy devices. The data packet group is sent to an agent device, different agent devices receive different data packet groups, the agent device stores and forwards the data packet group to other first devices connected with the agent device, the other first devices can judge whether the other first devices receive the data packet group when receiving the data packet group, and when the other first devices do not receive the data packet group, the other first devices store the data packet group and send the data packet group to other devices connected with the other first devices. After the first device receives all the data packets, a notification message may be sent to the target platform, the target platform receives and records the received notification message, and when it is determined that all the first devices receive all the data packets, an instruction is sent to the first device to instruct the first device to perform an upgrade operation.
Optionally, the execution subject of the above steps may be a target platform, a background processor, or other devices with similar processing capabilities, and may also be a machine integrated with at least a data processing device, where the data processing device may include a terminal such as a computer, a mobile phone, and the like, but is not limited thereto.
In the above embodiment, the target Device and the first Device may be 5G wireless network devices and have a Device to Device (D2D) function. Referring to fig. 5, as shown in fig. 5, an equipment connection schematic diagram in the equipment upgrading method is shown, where each internet of things terminal (corresponding to the first equipment) is started, functions of 5G, D2D are initialized, a connection is established between a 5G network and a cloud upgrading platform (corresponding to the target platform), and each internet of things terminal scans surrounding nodes through D2D and establishes a connection to construct a local area network. The cloud upgrading platform determines the number of agent nodes according to the current load condition (corresponding to the first device) and the number of devices in the current cluster (corresponding to the target device), and assumes that there are M agent upgrading nodes (corresponding to the agent devices). For example, the cloud upgrade platform selects devices B and F as proxy upgrade nodes. The agent upgrade node is responsible for upgrading the firmware of the agent upgrade node in addition to forwarding the upgrade packet (corresponding to the data packet). The cloud upgrading platform decomposes the firmware upgrading packet into N data blocks (corresponding to the target data packet), then averagely divides the data blocks into M equal parts, and each data packet (corresponding to the data packet group) is forwarded by one proxy node. For example, the size of the upgrade package is 100MB, the upgrade package is divided into 20 data blocks, the number of each data block is 1-20, the proxy node B forwards the data blocks with the numbers of 1-10, and the proxy node F forwards the data blocks with the numbers of 11-20. After receiving the data blocks of the upgrade package, the proxy node stores the data blocks locally, and then distributes all the data blocks to the nodes connected to the device, for example, proxy node B distributes the received data blocks to device A, C, D through D2D network. Also proxy node F will distribute the received data block to the device C, D, E connected to it. And after receiving the data block of the upgrade package, the common equipment node preferentially analyzes the block number, if the data block is currently existed, the common equipment node directly forwards the data block to other nodes, otherwise, the common equipment node firstly stores the data block to the local and then forwards the data block to other nodes. And after the data block of a certain device is completely received, sending a message to the cloud upgrading platform to inform the current upgrading state. Since the upgrading process of a certain device cannot help other devices to forward the data block, the upgrading speed of other devices can be reduced, and therefore after the cloud upgrading platform counts that all devices finish downloading the firmware, the upgrading command is sent again to inform the first device to execute the upgrading operation at the same time. It should be noted that the number of the agent upgrade nodes is limited and only one level of agent exists.
According to the method and the device, under the condition that an upgrading instruction is received, a first number of target devices connected with a target platform and a second number of first devices to be upgraded are obtained, a third number of proxy devices are determined in the first devices according to the first number and the second number, the data package for upgrading the first devices is divided into at least two target data packages, the at least two target data packages are divided into a third number of data package groups, the third number of data package groups are correspondingly sent to the third number of proxy devices to indicate the proxy devices to store the received data package groups, and the received data package groups are sent to other first devices connected with the proxy devices, so that the first devices execute upgrading operation according to the data packages after receiving all target data packages in the data packages. Since the data packets for upgrading can be divided into a third number of data packet groups, the data packet groups are respectively sent to different proxy devices, the proxy devices send the data packet groups to other first devices connected to the proxy devices, and the upgrading operation is executed after the first devices receive all the data packets. Therefore, the problem of low equipment upgrading speed in the related technology can be solved, and the equipment upgrading speed is improved.
In one exemplary embodiment, dividing the data packet for upgrading the first device into at least two target data packets includes: dividing the data packet into at least two sub-packets based on the first number and the second number; and coding at least two sub-data packets to obtain at least two target data packets, wherein the target data packets include the number corresponding to each target data packet and the fourth number of the at least two target data packets. In this embodiment, the data packet may be divided into at least two sub data packets according to the first number and the second number, the sub data packets are encoded, that is, the sub data packets are numbered, the total number of the divided data packets is added to the sub data packets, and the encoded sub data packets are determined as the target data packets. For example, the data packet is divided into 20 sub-packets, the 20 sub-packets are numbered, e.g., 1-20, respectively, and 20 is added to the sub-packets, e.g., the header information positions of the sub-packets.
In an exemplary embodiment, dividing at least two of the target packets into the third number of packet groups, and correspondingly sending the third number of packet groups to the third number of the proxy devices includes: determining attribute information of the agent device; determining a partitioning rule of the target data packet based on the attribute information; and dividing at least two target data packets into a third number of data packet groups based on the division rule, and correspondingly sending the third number of data packet groups to the third number of proxy devices. In this embodiment, the division rule of the target packet may be determined by the attribute information of the proxy device. For example, when the third number of proxy devices are the same type of proxy devices, that is, the performance is the same, the partition rule may be an average partition, that is, when the number of target packets is 20 and the proxy device is 2, the target packets may be equally partitioned into 2 packets to obtain 2 packet groups, and the first packet group is sent to the first proxy device, and the second packet group is sent to the second proxy device. Of course, when the performance of the proxy devices is different, a plurality of target packets may be allocated to the proxy device with high forwarding performance according to the performance of the proxy device. For example, when the number of destination packets is 20 and the number of agent devices is 2, if the forwarding performance of the first agent device is high, the first packet group may include 15 destination packets and the second packet group may include 5 destination packets. And sending the first data packet group to the agent equipment with high forwarding performance.
In one exemplary embodiment, determining the partition rule of the target packet based on the attribute information includes: determining a division rule of the target packet based on performance information and connection information included in the attribute information, wherein the connection information includes the number of devices to which the proxy device is connected. In this embodiment, the partition rule of the target packet may also be determined according to the performance information and the connection information of the proxy device. Namely, the division rule is determined according to the number of the agent devices connected with other first devices and the performance of the agent devices.
In an exemplary embodiment, after correspondingly transmitting the third number of packet groups to the third number of proxy devices, the method further includes: receiving and recording a data packet receiving result fed back by the first equipment; and under the condition that the first equipment is determined to finish receiving the data packet, sending an equipment upgrading instruction to the first equipment so as to instruct the first equipment to execute upgrading operation based on the data packet. In this embodiment, after the packet group is correspondingly sent to the proxy device, the proxy device may store and forward the packet group, and after receiving the packet group, the first device may analyze the number of the target packet and the total amount information of the target packet included in the packet group. After the first device receives all the data packets, the first device may feed back a data packet reception result to the target platform, and the target platform receives and records the reception result. And after determining that each first device receives the data packet, sending a device upgrading instruction to each first device, and after receiving the device upgrading instruction, executing upgrading operation according to the data packet by each first device. The receiving result may not include the device information of successful download and successful download.
In the foregoing embodiment, after the upgrade is completed, the first device may feed back a device upgrade completion notification to the target platform, and after receiving the notification, the target platform may send a restart instruction to each first device to instruct the first device to perform a restart operation. The restart instruction may be sent in a unified manner after all the devices are determined to have completed the upgrade operation, or may be sent directly to the upgraded devices after the notification is received. Of course, after the first device is upgraded, the device can be automatically restarted.
In this embodiment, an apparatus upgrading method is further provided, and fig. 6 is a second flowchart of the apparatus upgrading method according to the embodiment of the present invention, as shown in fig. 6, the flowchart includes the following steps:
step S602, receiving a data packet group sent by agent equipment, wherein the data packet group is obtained by dividing a data packet for upgrading first equipment to be upgraded by a target platform to obtain at least two target data packets and grouping the at least two target data packets;
step S604, analyzing the data packet group to determine the number of each target data packet included in the data packet group, wherein each target data packet includes the number corresponding to each target data packet;
step S606, saving the packet group when it is determined that the target packet corresponding to the number does not exist in the first device;
step S608, after determining that all the data packet groups included in the data packet are received, upgrading the first device based on all the received data packet groups.
In the above embodiment, the target platform may divide the data packet for upgrading the first device into at least two target data packets, and then divide the at least two data packets into a plurality of data packet groups. Wherein the number of packet groups may be the same as the number of proxy devices. The data packet group is stored and forwarded to other first devices connected with the agent device, and when the other first devices receive the data packet group, the data packet group can be analyzed to determine the number of each target data packet in each data packet group and judge whether the data packet group is received by the other first devices. And in the case that the target data packet corresponding to the number does not exist in the first device, namely when the first device does not receive the target data packet corresponding to the number, saving the target data packet. After determining that all of the data packets are received, the first device is upgraded based on the received all of the data packet sets.
Optionally, the main body of the above steps may be the first device, the background processor, or other devices with similar processing capabilities, and may also be a machine integrated with at least a data processing device, where the data processing device may include a terminal such as a computer, a mobile phone, and the like, but is not limited thereto.
In the above embodiment, the agent device may be a device determined by the target platform from the first devices to be upgraded. The target platform may determine the agent device and partition a data packet for upgrading the first device upon receiving the upgrade instruction. The upgrade instruction may be a user-triggered device upgrade instruction, and the target platform may be a cloud upgrade platform, such as a cloud server platform. One target platform can be connected with a plurality of devices, and under the condition that an upgrading instruction is received, a first number of target devices connected with the target platform and a second number of devices to be upgraded are obtained. The target device may be a device connected to the cloud platform and in an upgrade state, and/or a device which does not need to be upgraded, and the first device may be a device to be upgraded, and after determining the number of the target device and the number of the devices to be upgraded, the number of the agent devices is determined according to the two numbers. That is, the agent device may be assigned to the first device to be upgraded according to the processing capability of the target platform.
In the above embodiment, the target Device and the first Device may be 5G wireless network devices and have a Device to Device (D2D) function. Referring to fig. 5, as shown in fig. 5, an equipment connection schematic diagram in the equipment upgrading method is shown, where each internet of things terminal (corresponding to the first equipment) is started, functions of 5G, D2D are initialized, a connection is established between a 5G network and a cloud upgrading platform (corresponding to the target platform), and each internet of things terminal scans surrounding nodes through D2D and establishes a connection to construct a local area network. The cloud upgrading platform determines the number of agent nodes according to the current load condition (corresponding to the first device) and the number of devices in the current cluster (corresponding to the target device), and assumes that there are M agent upgrading nodes (corresponding to the agent devices). For example, the cloud upgrade platform selects devices B and F as proxy upgrade nodes. The agent upgrade node is responsible for upgrading the firmware of the agent upgrade node in addition to forwarding the upgrade packet (corresponding to the data packet). The cloud upgrading platform decomposes the firmware upgrading packet into N data blocks (corresponding to the target data packet), then averagely divides the data blocks into M equal parts, and each data packet (corresponding to the data packet group) is forwarded by one proxy node. For example, the size of the upgrade package is 100MB, the upgrade package is divided into 20 data blocks, the number of each data block is 1-20, the proxy node B forwards the data blocks with the numbers of 1-10, and the proxy node F forwards the data blocks with the numbers of 11-20. After receiving the data blocks of the upgrade package, the proxy node stores the data blocks locally, and then distributes all the data blocks to the nodes connected to the device, for example, proxy node B distributes the received data blocks to device A, C, D through D2D network. Also proxy node F will distribute the received data block to the device C, D, E connected to it. And after receiving the data block of the upgrade package, the common equipment node preferentially analyzes the block number, if the data block is currently existed, the common equipment node directly forwards the data block to other nodes, otherwise, the common equipment node firstly stores the data block to the local and then forwards the data block to other nodes. And after the data block of a certain device is completely received, sending a message to the cloud upgrading platform to inform the current upgrading state. Since the upgrading process of a certain device cannot help other devices to forward the data block, the upgrading speed of other devices can be reduced, and therefore after the cloud upgrading platform counts that all devices finish downloading the firmware, the upgrading command is sent again to inform the first device to execute the upgrading operation at the same time. It should be noted that the number of the agent upgrade nodes is limited and only one level of agent exists.
By the invention, a data packet group sent by the agent equipment is received, wherein the data packet group is a data packet group obtained by dividing a data packet for upgrading the first equipment to be upgraded by a target platform to obtain at least two target data packets, grouping the at least two target data packets, analyzing the data packet group, determining the number of each target data packet in the data packet group, storing the data packet group under the condition that the target data packet corresponding to the number does not exist in the first equipment, upgrading the first equipment based on all the received data packet groups after determining all the data packet groups in the received data packet, because the data packet for upgrading can be divided into the data packet groups, the data packet groups are respectively sent to different agent equipment, and the data packet groups are sent to other first equipment connected with the agent equipment by the agent equipment, and after the first equipment receives all the data packets, the upgrading operation is executed.
