[1. Example of judging the supply data]

First, the supply management module 10 receives the supply data of the network device A (client). For example, the parameters for the installation data of network device A shown in Table 1 below include device number, device IP, communication protocol, device type, region, service type, etc., but are not limited thereto.

Next, the supply management module 10 sends the supply data to the supply data module 20 , so that the equipment adaptor 21 of the supply data module 20 imports the data of the supply data. Moreover, the configuration of the device adaptor 21 is scheduled and generated by the device adaptor management component 22 during system initialization, and imported into the relevant service parameters of the device adaptor 21 . For example, the service parameters of the device adaptor 21 shown in Table 2 below may include service ID, service name, service rate, service priority, committed message rate (CIR), extra message rate (EIR), and may further include alertness, Region (see Table 3), etc., But not limited to this.

Next, the equipment adaptor 21 assembles the supply data according to the required service parameters, and marks the relevant weights of the service parameters into the supply weight data. For example, the provisioning weight data compiled and marked by the device adaptor 21 from the device adaptor management element 22 shown in Table 3 below include data number, service rate, service priority, alertness, region, committed message rate (CIR), extra message rate (EIR), etc., but not limited thereto.

0.390625-0.140625=0.46875。機敏度之參數以3為門檻值，而計算出機敏度之參數的不純度=

，且地域之參數的不純度=

。承諾訊息速率(CIR)之參數以50,000為門檻值，而計算出承諾訊息速率(CIR)之參數的不純度=

。額外訊息速率(EIR)之參數以200,000為門檻值，而計算出額外訊息速率(EIR)之參數的不純度=

。 Furthermore, the device adaptor 21 can calculate each parameter of the supply weight data through the selection function of the supply data module 20 . For example, when the device adaptor 21 calculates the impurity value of each parameter of the weight data for installation, it can divide the parameter of service priority into two categories with a threshold value of 3, and calculate the parameter of service priority. Impurity =

0.390625-0.140625=0.46875. The parameter of alertness takes 3 as the threshold value, and the impurity of the parameter of alertness is calculated =

, and the impurity of the parameters of the region =

. The committed message rate (CIR) parameter takes 50,000 as the threshold, and the impurity of the committed message rate (CIR) parameter is calculated =

. The parameter of the extra information rate (EIR) takes 200,000 as the threshold value, and the impurity of the parameter of the extra information rate (EIR) is calculated =

.

Then, the device adaptor 21 can select the minimum value of impurity as the root node, and the impurity of the parameter of alertness is the minimum value of 0.375, indicating that the selection function selects the data numbers 4 and 5 in Table 3 as relatively important. Next, the selection function finds the most important value between data numbers 4 and 5, and the committed message rate (CIR) parameter and the extra message rate (EIR) parameter of data number 5 are respectively higher than the aforementioned threshold of 50,000 and 200,000, so after calculating the impurity again, the device adaptor 21 can know that the weight of the data number 5 is higher, so the device adaptor 21 will perform the hash value operation, and obtain the hash value “b2832f666f5435b1ac8291c52d8c8fd2b481733406bd26db8d627eb9ca21764a” after calculating the hash value according to the sha256 hash value , and then send the hash value to the block data module 40 .

Finally, in the process of storing the supply data in the blockchain 70, the block data module 40 will issue a smart contract to the blockchain 70, and the content of the smart contract is to store the hash value calculated with a higher weight. For the supply and installation data, the consensus node (C-Node) of the blockchain 70 will be responsible for verifying the correctness of the supply and installation data and establish a block, thereby completing the storage of the supply and installation data in the block. chain 70.

[2. Example of supplying data verification]

First of all, when supplying and installing data of No. 5 (see Equipment No. 5 in Table 1), the supply and installation management module 10 needs to check the correctness of the supply and installation data, and then send the supply and installation data to the supply and installation data module 20 . When the supply data module 20 receives the supply data of No. 5 for verification, it first determines whether the supply data of No. 5 (see data No. 5 in Table 3) is the supply data with a higher weight. If the supply data has a higher weight, the supply data module 20 calculates a hash value (such as a sha256 hash value) according to the content of the supply data, and then calls the query module through the application program interface module 30 with the calculated hash value. 60. Then, the query module 60 searches (inquires or compares) whether there is a value in the blockchain 70 according to the hash value calculated by the supply data module 20, and if there is a value in the blockchain 70, the query module 60 The correct result is returned to the supply data module 20 through the application programming interface module 30, and then the supply data module 20 returns the correct parameters of the supply data after the comparison to the supply management module 10, so as to facilitate The provisioning management module 10 performs the correct provisioning operation of the network device A.

As shown in the figure, in step S11 of FIG. 2 , the supply data is prepared to be written into the blockchain 70 or the database 80 . In steps S12 and S13 of FIG. 2, the supply data module 20 reads the supply data to determine the importance of the supply data? If the supply data module 20 determines that the importance of the supply data is "important", the supply data will be written into the blockchain 70; otherwise, if the supply data module 20 determines the importance of the supply data If it is "Normal, Minor, Unimportant", the supply data is written into the database 80.

In step S23 in FIG. 3 , a block data module 40 uses a consensus decision algorithm to deliver the block to the nodes of the blockchain 70 , so as to deploy the blocks in the nodes of the blockchain 70 .

In step S24 in FIG. 3 , a data verification module 50 verifies the content of the supply data of the network device A and the format of the supply data, so as to write the supply data after confirming that the supply data is correct Blockchain 70.
