[0019] In an embodiment, as Figure 2 shown, a kind of ONU gateway Mesh submachine software version synchronization method based on the upgrade is provided, to the method application in Figure 1 The server in example is described, including the following steps: S1: initial trigger is carried out. Specifically, when the host detects that new version is available, update instruction is sent to at least one core submachine;The submachine receives update instruction and updates. Exemplarily, when the host detects that new version is available, mark itself as synchronization source node, and the host sends update instruction to at least one core submachine (such as RSSI best node) by management signaling;The submachine receiving update instruction updates.

[0020] S2: spread synchronization is carried out. Specifically, the upgraded submachine carries out spread synchronization to the new version identification information to adjacent submachine through periodic broadcast. Exemplarily, the upgraded submachine carries the new version identification information in the management frame or dedicated Mesh data frame of periodic broadcast;After receiving the broadcast of the new version identification information higher than its own version, the adjacent submachine automatically triggers download request. Preferably, the image data of the new version can be pulled from the adjacent submachine by P2P mode.

[0021] S3: hierarchical verification is carried out. Specifically, the new version is verified hierarchically, and when verification fails, the upper submachine retransmits;If the number of retransmission failures exceeds the threshold, it is rolled back to the host to reacquire. Exemplarily, the hierarchical verification includes: CRC or Hash verification is carried out after each data block transmission.

[0022] S4: Confirmation and status summary; specifically, after the slave device completes the update, it broadcasts a synchronized flag. For example, after the slave device completes the update, it broadcasts a "synchronized" flag in a Beacon or status frame; the host periodically collects the synchronization progress of the entire network to determine whether the closed loop has been completed.

[0023] Furthermore, the method provided in this embodiment of the invention may also include the steps of load balancing and rate control. Specifically, the slave unit is set to have a maximum number of simultaneous transmission connections; neighboring slave units are dynamically selected using RSSI or delay information to avoid overload; and the transmission interval is controlled to balance CPU and bandwidth usage.

[0024] Furthermore, the method provided in this embodiment of the invention may also include a step of handling abnormal situations. Specifically, for the slave devices that failed to update, automatic propagation synchronization is performed again in subsequent cycles. The reasons for the failed update may include: disconnection, weak signal, or corrupted version, etc. This ensures the eventual consistency of the overall network version.

[0025] The ONU gateway Mesh slave software version synchronization method based on propagating upgrades provided in this invention adopts a hierarchical verification and retransmission mechanism to ensure the integrity of version synchronization and improve reliability; transmission tasks are automatically distributed among nodes to avoid overload of the master node; the propagation mechanism can adapt to multi-level and complex topology Mesh networks, with strong scalability; distributed data transmission reduces centralized congestion, improves overall transmission efficiency, and has high bandwidth utilization; self-healing capability allows for automatic secondary compensation updates for failed nodes to ensure eventual consistency; and it avoids broadcast storms and latency jitter caused by centralized updates, improving stability. This invention can be applied to Fiber to the Room (FTTR), enterprise-level Fiber to the Room-Business (FTTR-B), and broadband converged terminal products.

[0026] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0027] In one embodiment, a software version synchronization device for an ONU gateway Mesh slave unit based on a propagating upgrade is provided. This software version synchronization device for an ONU gateway Mesh slave unit based on a propagating upgrade corresponds one-to-one with the software version synchronization method for an ONU gateway Mesh slave unit based on a propagating upgrade described in the above embodiments. Figure 3 As shown, the ONU gateway Mesh sub-machine software version synchronization device based on propagation upgrade includes a host 100 and several sub-machines 200; wherein, The host 100 includes an initial triggering module 101 for initial triggering. Specifically, when the host detects that a new version is available, it sends an update command to at least one core slave machine; the slave machine receives the update command and performs the update. For example, when the host detects that a new version is available, it marks itself as a synchronization source node, and the host sends an update command to at least one core slave machine (such as the RSSI best node) via management signaling; the slave machine receiving the update command performs the update.

[0028] The slave device 200 includes a propagation synchronization module 201 for performing propagation synchronization. Specifically, this may include: the upgraded slave device periodically broadcasting the new version identification information to neighboring slave devices. For example, the upgraded slave device carries the new version identification information in the periodically broadcast management frame or dedicated Mesh data frame; upon receiving a broadcast with new version identification information higher than its own version, the neighboring slave device automatically triggers a download request. Preferably, the mirror data of the new version can be retrieved in segments from the neighboring slave devices via P2P.

[0029] The slave device 200 also includes a verification module 202 for hierarchical verification. Specifically, the verification module performs hierarchical verification on the new version. If verification fails, the upstream slave device retransmits the data. If the number of failed retransmissions exceeds a threshold, the process falls back to the host device to re-acquire the data. For example, the hierarchical verification includes performing CRC or Hash verification after each data block is transmitted.

[0030] The slave device 200 also includes a completion confirmation module 203, used for completion confirmation. The completion confirmation module broadcasts a synchronized flag after the slave device completes the update. For example, after the update is completed, a "synchronized" flag is broadcast in a Beacon or status frame.

[0031] The host 100 also includes a closed-loop module 102, which is used to periodically collect the synchronization progress of the entire network and determine whether the closed loop has been completed.

[0032] Furthermore, the slave unit 200 may also include a load balancing and rate control module for performing load balancing and rate control. Specifically, the load balancing and rate control module sets a maximum number of simultaneous transmission connections for the slave unit; dynamically selects neighboring slave units using RSSI or latency information to avoid overload; and controls the transmission interval to balance CPU and bandwidth usage.

[0033] Furthermore, the slave unit 200 may also include an anomaly handling module for handling abnormal situations. Specifically, if the anomaly handling module detects a slave unit that has failed to update, it automatically performs a propagation synchronization again in subsequent cycles. The reasons for the failed update may include: disconnection, weak signal, or corrupted version. This ensures the eventual consistency of the overall network version. This embodiment of the invention can be applied to Fiber To The Room (FTTR), Fiber To The Room-Business (FTTR-B), and broadband converged terminal products.
