Obviously, the drawings described below are only some embodiments recorded in the present application. For ordinary technicians in this field, other drawings can also be obtained based on these drawings.

DETAILED DESCRIPTION

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0018] The present application proposes a method and system for verifying variable data, wherein variable data refers to variable data related to "lottery", such as variable information on the ticket, serial number, barcode and other data. The above data is defined as variable data, and the data department of the operating company forms the variable data into a corresponding variable data file, and generates a test IJP data file according to the variable data file. During the production process, the variable data needs to be transmitted to form an IJP data file. In this process, the present embodiment aims to build a relatively secure transmission link, and verify the transmission link and the variable data transmitted using the transmission link. If the transmission link verification passes, and the subsequent variable data transmitted using the transmission link verification still passes, it means that the transmission link is secure, and the remaining variable data will still be transmitted using the verified transmission link, thereby ensuring the security of the subsequent variable data transmission and improving the success rate of data transmission.

[0019] Embodiment 1 like Figure 1 As shown, this embodiment provides a method for verifying variable data, which specifically includes the following steps: Step S1: Obtain variable data.

[0020] The variable data refers to the variable data related to "lottery", such as variable information on the ticket, serial number, barcode and other data, and the above data is defined as variable data.

[0021] Step S2: After obtaining the variable data, multiple transmission links are constructed.

[0022] In this embodiment, virtual nodes are used to transmit variable data, and the virtual nodes include virtual root nodes, virtual middle nodes, and virtual leaf nodes. The selected virtual root nodes, virtual middle nodes, and virtual leaf nodes are connected for communication to finally form a topology structure and complete the construction of the transmission link.

[0023] Generally speaking, the number of root nodes is 1, and the number of virtual mid-path nodes and virtual leaf nodes is multiple. However, in order to save costs, this embodiment constructs the following transmission links: A virtual root node is communicatively connected to P virtual mid-path nodes, and each of the P virtual mid-path nodes is communicatively connected to a virtual leaf node, so as to form a transmission link A.

[0024] A root node is communicatively connected to Q virtual middle road nodes, the Q virtual middle road nodes are respectively connected to V virtual middle road nodes, the V virtual middle road nodes are communicatively connected to a virtual leaf node, to form a transmission link B.

[0025] The above communication connection can be understood as a connection relationship formed by each node being able to send requests to each other.

[0026] In terms of specific numerical values, the number P<the number Q<the number V. The number of virtual nodes included in the transmission link A is smaller than the number of virtual nodes included in the transmission link B.

[0027] Step S3: Perform transmission verification on the transmission link according to the variable data.

[0028] The variable data transmitted once is used as a verification sample to perform transmission verification on the transmission link, which specifically includes the following sub-steps: Step S31: Determine the amount of variable data to be transmitted at one time.

[0029] Step S32: Select a transmission link that needs to be verified according to the amount of variable data transmitted at one time.

[0030] In the above steps, multiple transmission links are determined. If the amount of variable data transmitted at one time is less than a specified threshold, in order to reduce costs and save time as much as possible, this embodiment preferentially enables transmission link A for transmission of variable data.

[0031] On the contrary, if the amount of variable data transmitted at one time is greater than the specified threshold, transmission link B is enabled to transmit the variable data.

[0032] Step S33: verify the selected transmission link to determine whether the verification is successful.

[0033] Before the verification is performed, the corresponding bandwidth of the virtual node in the transmission link is determined.

[0034] The bandwidth of a virtual node refers to the amount of data that a virtual node can transmit per unit time. For example, in a cloud service provider's data center, the bandwidth of a virtual node determines how fast it can receive and send data.

[0035] During data transmission, bandwidth cannot be fully utilized or bandwidth performance is reduced due to various factors. For example, during communication between nodes, there is theoretically 100Mbps bandwidth, but due to various obstacles, the actual bandwidth that can be effectively utilized may be only 60Mbps. This will greatly reduce the speed of receiving and sending data.

[0036] Therefore, this embodiment calculates the bandwidth barrier value of the transmission link according to the bandwidth of the virtual node in the transmission link. The bandwidth barrier value reflects whether the transmission rate of the transmission link can meet the requirement. When the bandwidth barrier value is less than the specified threshold, it means that the transmission rate of the transmission link can meet the requirement, and the verification is considered to be passed. Otherwise, the verification fails.

[0037] The bandwidth barrier value of the transmission link is specifically expressed as: ; in, represents the bandwidth barrier value of transmission link x, M represents the number of nodes in transmission link x, and I represents the number of nodes in transmission link x whose bandwidth is less than the specified threshold. Indicates the number of times the available bandwidth of a node in transmission link x, whose bandwidth is less than the specified threshold, decreases within a specified historical period. Indicates the number of times the available bandwidth of the remaining nodes in the transmission link x is reduced after removing the nodes whose bandwidth is less than the specified threshold.

[0038] When the transmission verification is passed, step S4 is executed. If the verification fails, the process exits. As another embodiment, when verification fails, nodes with bandwidths less than a specified threshold are removed and new nodes are added.

[0039] After the addition of the new node is completed, the above formula is still used to confirm the bandwidth barrier value in the transmission link x after the addition of the new node. If the bandwidth barrier value passes, in order to ensure the security of transmission and improve the success rate of data transmission, this embodiment also verifies the transmission time of the transmission link x after the addition of the new node.

[0040] The transmission time is expressed as: ; in represents the transmission time of transmission link x, Q represents the amount of variable data received, L represents the number of nodes in transmission link x after adding nodes, represents the bandwidth utilization of node i in transmission link x, Represents the total bandwidth of transmission link x.

[0041] If the transmission time is greater than the specified threshold, it is considered that the transmission link x after adding the node still cannot complete the data transmission well, the verification fails, and the process exits. Otherwise, it is considered that the verification passes, and step S4 is executed.

[0042] Step S4: If the transmission verification passes, use the transmission link to transmit the variable data.

[0043] Taking transmission link A as an example, if transmission link A passes the verification, transmission link A is used to transmit variable data.

[0044] Specifically, the variable data is input by the virtual root node, the virtual root node sends a transmission request to the virtual middle node, and the variable data is transmitted to one or more virtual middle nodes. After receiving the variable data, the one or more virtual middle nodes send a data transmission request to the virtual leaf node, and the virtual leaf node receives the variable data.

[0045] Step S5: Verify the variable data being transmitted.

[0046] After receiving the variable data, the virtual leaf node performs data verification on the transmitted variable data. In the process of data verification, the variable data is divided into multiple data blocks, and data verification is performed on the multiple data blocks respectively.

[0047] Based on the above, step S5 includes the following sub-steps: Step S51: Divide the variable data received by the virtual leaf node into a final ticket variable information data block, a final serial number data block and a final barcode data block.

[0048] Step S52: Divide the acquired variable data into an original ticket variable information data block, an original serial number data block and an original barcode data block.

[0049] Specifically, the variable data obtained in step S1 is divided into an original ticket variable information data block, an original serial number data block and an original barcode data block.

[0050] Step S52: verify the final ticket variable information data block, the final serial number data block and the final barcode data block according to the original ticket variable information data block, the original serial number data block and the original barcode data block.

[0051] Each byte in the final ticket variable information data block, the final serial number data block, and the final barcode data block is added together (generally ignoring the carry bit) to obtain a sum, which is specifically expressed as: ; Where S represents the total number of bytes in the final ticket variable information data block (or final serial number data block, final barcode data block), The byte sequence representing the final ticket variable information data block (or final serial number data block, final barcode data block). Mod 256 represents the modulo operation.

[0052] The byte sum of the original ticket variable information data block (or the final serial number data block, the final barcode data block) is calculated according to the above formula, and the calculated byte sum is compared with the byte sum of the original ticket variable information data block (or the original serial number data block, the original barcode data block). If they are consistent, it is considered that the data verification has passed, and step S6 is executed. Otherwise, it is considered that the data verification has failed.

[0053] If data verification fails, it means that there may be abnormalities in the transmission link, the data itself, and the data during transmission. Data transmission will no longer be performed and the process will exit.

[0054] Step S6: If the data verification passes, the transmission link is used to perform final transmission of the variable data.

[0055] If the data verification is passed, the virtual leaf node will eventually send the variable data to the data processing center, such as the data department of the operating company. The data processing center will form the received variable data into a variable data file, and can generate a test IJP data file based on the variable data file.

[0056] Embodiment 2 like Figure 2 As shown, this embodiment provides a variable data verification system, which specifically includes: a variable data acquisition unit 210, a transmission link construction unit 220, a transmission verification unit 230, a data transmission execution unit 240, a data verification unit 250 and a final transmission execution unit 260.

[0057] The variable data acquisition unit 210 is used to acquire variable data.

[0058] The variable data refers to the variable data related to "lottery", such as variable information on the ticket, serial number, barcode and other data, and the above data is defined as variable data.

[0059] The transmission link construction unit 220 is used to construct multiple transmission links.

[0060] In this embodiment, virtual nodes are used to transmit variable data, and the virtual nodes include virtual root nodes, virtual middle nodes, and virtual leaf nodes. The selected virtual root nodes, virtual middle nodes, and virtual leaf nodes are connected for communication to finally form a topology structure and complete the construction of the transmission link.

[0061] Generally speaking, the number of root nodes is 1, and the number of virtual mid-path nodes and virtual leaf nodes is multiple. However, in order to save costs, this embodiment constructs the following transmission links: A virtual root node is communicatively connected to P virtual mid-path nodes, and each of the P virtual mid-path nodes is communicatively connected to a virtual leaf node, so as to form a transmission link A.

[0062] A root node is communicatively connected to Q virtual middle road nodes, the Q virtual middle road nodes are respectively connected to V virtual middle road nodes, the V virtual middle road nodes are communicatively connected to a virtual leaf node, to form a transmission link B.

[0063] The above communication connection can be understood as a connection relationship formed by each node being able to send requests to each other.

[0064] In terms of specific numerical values, the number P<the number Q<the number V. The number of virtual nodes included in the transmission link A is smaller than the number of virtual nodes included in the transmission link B.

[0065] The transmission verification unit 230 is used to perform transmission verification on the transmission link according to the variable data.

[0066] The variable data transmitted once is used as a verification sample to perform transmission verification on the transmission link.

[0067] The transmission verification unit 230 includes the following submodules: a data volume determination module, a link selection module, a determination module, and a node addition module.

[0068] The data volume determination module is used to determine the volume of variable data to be transmitted at one time.

[0069] The link selection module is used to select a transmission link that needs to be verified according to the amount of variable data transmitted at one time.

[0070] In the above steps, multiple transmission links are determined. If the amount of variable data transmitted at one time is less than a specified threshold, in order to reduce costs and save time as much as possible, this embodiment preferentially enables transmission link A for variable data transmission. On the contrary, if the amount of variable data transmitted at one time is greater than the specified threshold, transmission link B is enabled for variable data transmission.

[0071] The determination module is used to verify the selected transmission link and determine whether the verification is passed.

[0072] Before the verification is performed, the corresponding bandwidth of the virtual node in the transmission link is determined.

[0073] The bandwidth of a virtual node refers to the amount of data that a virtual node can transmit per unit time. For example, in a cloud service provider's data center, the bandwidth of a virtual node determines how fast it can receive and send data.

[0074] During data transmission, bandwidth cannot be fully utilized or bandwidth performance is reduced due to various factors. For example, during communication between nodes, there is theoretically 100Mbps bandwidth, but due to various obstacles, the actual bandwidth that can be effectively utilized may be only 60Mbps. This will greatly reduce the speed of receiving and sending data.

[0075] Therefore, this embodiment calculates the bandwidth barrier value of the transmission link according to the bandwidth of the virtual node in the transmission link. The bandwidth barrier value reflects whether the transmission rate of the transmission link can meet the requirement. When the bandwidth barrier value is less than the specified threshold, it means that the transmission rate of the transmission link can meet the requirement, and the verification is considered to be passed. Otherwise, the verification fails.

[0076] The bandwidth barrier value of the transmission link is specifically expressed as: ; in, represents the bandwidth barrier value of transmission link x, M represents the number of nodes in transmission link x, and I represents the number of nodes in transmission link x whose bandwidth is less than the specified threshold. Indicates the number of times the available bandwidth of a node in transmission link x, whose bandwidth is less than the specified threshold, decreases within a specified historical period. It represents the number of times the available bandwidth of the remaining nodes in the transmission link x is reduced after removing the nodes whose bandwidth is less than the specified threshold. When the transmission verification is passed, the data transmission execution unit 240 is executed. If the verification fails, the process exits.

[0077] As another embodiment, it further comprises a node adding module. When the transmission verification fails, the node adding module removes nodes whose bandwidth is less than a specified threshold and adds new nodes.

[0078] After the addition of the new node is completed, the above formula is still used to confirm the bandwidth barrier value in the transmission link x after the addition of the new node. If the bandwidth barrier value passes, in order to ensure the security of transmission and improve the success rate of data transmission, this embodiment also verifies the transmission time of the transmission link x after the addition of the new node.

[0079] The transmission time is expressed as: ; in represents the transmission time of transmission link x, Q represents the amount of variable data received, L represents the number of nodes in transmission link x after adding nodes, represents the bandwidth utilization of node i in transmission link x, Represents the total bandwidth of transmission link x.

[0080] If the transmission time is greater than the specified threshold, it is considered that the transmission link x after adding the node still cannot complete the data transmission well, the verification fails, and the process exits. Otherwise, it is considered that the verification passes, and the data transmission execution unit 240 is executed.

[0081] The data transmission execution unit 240 is used to transmit variable data using the verified transmission link.

[0082] Taking transmission link A as an example, if transmission link A passes the verification, transmission link A is used to transmit variable data.

[0083] Specifically, the variable data is input by the virtual root node, the virtual root node sends a transmission request to the virtual middle node, and the variable data is transmitted to one or more virtual middle nodes. After receiving the variable data, the one or more virtual middle nodes send a data transmission request to the virtual leaf node, and the virtual leaf node receives the variable data.

[0084] The data verification unit 250 is used to verify the variable data being transmitted.

[0085] After receiving the variable data, the virtual leaf node performs data verification on the transmitted variable data. In the process of data verification, the variable data is divided into multiple data blocks, and data verification is performed on the multiple data blocks respectively.

[0086] The data verification unit 250 includes the following submodules: a final data block division module, an original data block division module, and a verification module.

[0087] The final data block division module is used to divide the variable data received by the virtual leaf node into the final ticket variable information data block, the final serial number data block and the final barcode data block.

[0088] The original data block division module is used to divide the acquired variable data into the original ticket variable information data block, the original serial number data block and the original barcode data block.

[0089] The verification module is used to verify the final ticket variable information data block, the final serial number data block and the final barcode data block based on the original ticket variable information data block, the original serial number data block and the original barcode data block.

[0090] Each byte in the final ticket variable information data block, the final serial number data block, and the final barcode data block is added together (generally ignoring the carry bit) to obtain a sum, which is specifically expressed as: ; Where S represents the total number of bytes in the final ticket variable information data block (or final serial number data block, final barcode data block), The byte sequence representing the final ticket variable information data block (or final serial number data block, final barcode data block). Mod 256 represents the modulo operation.

[0091] The byte sum of the original ticket variable information data block (or the final serial number data block, the final barcode data block) is calculated according to the above formula, and the calculated byte sum is compared with the byte sum of the original ticket variable information data block (or the original serial number data block, the original barcode data block). If they are consistent, it is considered that the data verification has passed, and step S6 is executed. Otherwise, it is considered that the data verification has failed.

[0092] If data verification fails, it means that there may be abnormalities in the transmission link, the data itself, and the data during transmission. Data transmission will no longer be performed and the process will exit.

[0093] The final transmission execution unit 260 is used to use the transmission link to perform final transmission of the variable data if the data verification passes.

[0094] If the data verification is passed, the virtual leaf node will eventually send the variable data to the data processing center, such as the data department of the operating company. The data processing center will form the received variable data into a variable data file, and can generate a test IJP data file based on the variable data file.
