[0019] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0020] The present application provides a variable data verification method and system, wherein the variable data refers to "lottery" related variable data, such as ticket variable information, serial number and barcode data, etc. The above data is defined as variable data. The variable data is formed into a corresponding variable data file by the data department of the operating company, and a test IJP data file is generated according to the variable data file.

[0021] Embodiment one

[0022] As shown in Figure 1 , the present embodiment provides a variable data verification method, which specifically includes the following steps:

[0023] Step S1: obtaining variable data.

[0024] The variable data refers to "lottery" related variable data, such as ticket variable information, serial number and barcode data, etc. The above data is defined as variable data.

[0025] Step S2: After obtaining the variable data, a plurality of transmission links are constructed.

[0026] In the embodiment, the variable data is transmitted by using virtual nodes, which include a virtual root node, virtual intermediate nodes and virtual leaf nodes. The selected virtual root node, virtual intermediate nodes and virtual leaf nodes are communicatively connected to form a topology structure, and the construction of the transmission links is completed.

[0027] Generally, the number of root nodes is one, and the number of virtual intermediate nodes and virtual leaf nodes is multiple. In order to save costs, the following transmission links are constructed in the embodiment.

[0028] One virtual root node is communicatively connected with P virtual intermediate nodes, and the P virtual intermediate nodes are each communicatively connected with one virtual leaf node to form a transmission link A.

[0029] One root node is communicatively connected with Q virtual intermediate nodes, and the Q virtual intermediate nodes are respectively connected with V virtual intermediate nodes, and the V virtual intermediate nodes are communicatively connected with one virtual leaf node to form a transmission link B.

[0030] The above-mentioned communicatively connection can be understood as a connection relationship formed by the fact that each node can send a request to each other.

[0031] In terms of specific numerical values, the number P is less than the number Q, and the number Q is less than the number V. The number of virtual nodes included in the transmission link A is less than the number of virtual nodes included in the transmission link B.

[0032] Step S3: Transmission verification is performed on the transmission link according to the variable data.

[0033] In the embodiment, the variable data transmitted once is used as a verification sample to perform transmission verification on the transmission link, which includes the following sub-steps.

[0034] Step S31: The data amount of the variable data transmitted once is determined.

[0035] Step S32: The transmission link to be verified is selected according to the data amount of the variable data transmitted once.

[0036] In the above-mentioned steps, a plurality of transmission links are determined. When the data amount of the variable data transmitted once is less than a specified threshold value, in order to reduce costs and save time as much as possible, the transmission link A is preferentially enabled to transmit the variable data.

[0037] Conversely, when the data amount of the variable data transmitted once is greater than the specified threshold value, the transmission link B is enabled to transmit the variable data.

[0038] Step S33: verifying the selected transmission link, and determining whether the verification is passed.

[0039] Before the verification, further comprising determining the corresponding bandwidth of the virtual nodes in the transmission link.

[0040] The bandwidth of the virtual node refers to the amount of data that the virtual node can transmit in a unit of time. For example, in a data center of a cloud service provider, the bandwidth of the virtual node determines how fast it can receive and send data.

[0041] In the process of data transmission, the bandwidth cannot be fully utilized or the bandwidth performance decreases due to various factors. For example, in the process of communication between nodes, there is theoretically 100 Mbps of bandwidth, but due to various obstacles, the bandwidth that can be effectively utilized may only be 60 Mbps. This will greatly reduce the speed of receiving and sending data.

[0042] Therefore, the embodiment calculates the bandwidth obstruction value of the transmission link according to the bandwidth of the virtual nodes in the transmission link. The bandwidth obstruction value reflects whether the transmission rate of the transmission link can meet the requirements. When the bandwidth obstruction value is less than a specified threshold, it means that the transmission rate of the transmission link can meet the requirements, and it is considered that the verification is passed. Otherwise, the verification is not passed.

[0043] The bandwidth obstruction value of the transmission link is specifically represented as:

[0044] ;

[0045] Wherein, The bandwidth obstruction value of the transmission link x, M represents the number of nodes in the transmission link x, I represents the number of nodes in the transmission link x whose bandwidth is less than the specified threshold, The number of times of available bandwidth reduction of the nodes in the transmission link x whose bandwidth is less than the specified threshold in the specified historical time period, The number of times of available bandwidth reduction of the remaining nodes in the transmission link x after excluding the nodes whose bandwidth is less than the specified threshold.

[0046] When the transmission verification is passed, step S4 is performed. If the verification fails, the flow is exited,

[0047] As another embodiment, when the verification fails, the nodes whose bandwidth is less than the specified threshold are removed, and the addition of new nodes is performed.

[0048] After the addition of new nodes is completed, the bandwidth obstruction value of the transmission link x after the addition of new nodes is still confirmed using the above formula. If the bandwidth obstruction value is passed, in order to ensure the safety of transmission and improve the success rate of data transmission, the embodiment further performs transmission time verification on the transmission link x after the addition of new nodes.

[0049] The transmission time is represented as:

[0050]

[0051] The transmission time of the transmission link x is represented as T x, the data amount of the received variable data is represented as Q, the number of nodes of the transmission link x after adding the node is represented as L, The bandwidth utilization rate of the node i in the transmission link x is represented as U i, the total bandwidth of the transmission link x is represented as B x. The total bandwidth of the transmission link x is represented as B x.

[0052] If the transmission time is greater than a specified threshold value, it is considered that the transmission link x after adding the node still cannot well complete the data transmission, the verification fails, and the process exits. Otherwise, it is considered that the verification passes, and step S4 is performed.

[0053] Step S4: If the transmission verification passes, the transmission link is used for the transmission of the variable data.

[0054] For example, if the transmission link A passes the verification, the transmission link A is used for the transmission of the variable data.

[0055] Specifically, the variable data is input from the virtual root node, the virtual root node sends a transmission request to the virtual intermediate node, the variable data is transmitted to one or more virtual intermediate nodes, the one or more virtual intermediate nodes receive the variable data and send a data transmission request to the virtual leaf node, and the virtual leaf node receives the variable data.

[0056] Step S5: Data verification is performed on the variable data in the transmission.

[0057] After the virtual leaf node receives the variable data, data verification is performed on the variable data after the transmission. 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.

[0058] Based on the above, step S5 includes the following sub-steps:

[0059] Step S51: The variable data received by the virtual leaf node is divided into a final ticket surface variable information data block, a final serial number data block, and a final barcode data block.

[0060] Step S52: The obtained variable data is divided into an original ticket surface variable information data block, an original serial number data block, and an original barcode data block.

[0061] Specifically, the variable data obtained in step S1 is divided into an original ticket surface variable information data block, an original serial number data block, and an original barcode data block. ​​

[0062] Step S52: verifying 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.

[0063] wherein each byte in the final ticket variable information data block, the final serial number data block and the final barcode data block is added (generally ignoring the carry) to obtain a total, which is specifically expressed as:

[0064] ;

[0065] wherein S represents the byte total in the final ticket variable information data block (or the final serial number data block, the final barcode data block), represents the byte sequence of the final ticket variable information data block (or the final serial number data block, the final barcode data block), and mod 256 represents the modulo operation.

[0066] wherein the byte total 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 total is compared with the byte total of the original ticket variable information data block (or the original serial number data block, the original barcode data block), and if they are consistent, it is considered that the data verification is passed, and step S6 is executed. Otherwise, it is considered that the data verification is not passed.

[0067] If the data verification fails, it means that the transmission link, the data itself and the data in the transmission process may be abnormal, and the data transmission is not performed, and the flow exits.

[0068] Step S6: if the data verification is passed, the final transmission of the variable data is performed using the transmission link.

[0069] wherein if the data verification is passed, the virtual leaf node finally sends the variable data to the data processing center, such as the data department of the operating company. The data processing center forms the variable data received into a variable data file, and can generate a test IJP data file according to the variable data file.

[0070] Embodiment Two

[0071] As shown in Figure 2 , the embodiment provides a variable data verification system, which specifically comprises 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.

[0072] The variable data acquisition unit 210 is used for acquiring variable data.

[0073] The variable data refers to lottery-related variable data, such as ticket variable information, serial numbers, bar codes, and the like.

[0074] The transmission link construction unit 220 is configured to construct a plurality of transmission links.

[0075] The virtual nodes include a virtual root node, a virtual intermediate node, and a virtual leaf node.

[0076] Generally, the number of root nodes is one, and the number of virtual intermediate nodes and virtual leaf nodes is multiple.

[0077] One virtual root node is communicatively connected with P virtual intermediate nodes, and the P virtual intermediate nodes are each communicatively connected with one virtual leaf node to form a transmission link A.

[0078] One root node is communicatively connected with Q virtual intermediate nodes, and the Q virtual intermediate nodes are each connected with V virtual intermediate nodes, and the V virtual intermediate nodes are communicatively connected with one virtual leaf node to form a transmission link B.

[0079] The communicatively connection can be understood as a connection relationship formed by the ability of each node to send a request to each other.

[0080] In specific numerical values, the number P is less than the number Q, and the number Q is less than the number V.

[0081] The transmission verification unit 230 is configured to perform transmission verification on the transmission link according to the variable data.

[0082] The variable data of one transmission is used as a verification sample to perform transmission verification on the transmission link.

[0083] The transmission verification unit 230 includes the following sub-modules: a data amount determination module, a link selection module, a determination module, and a node addition module.

[0084] The data amount determination module is configured to determine the data amount of the variable data of one transmission.

[0085] The link selection module is configured to select the transmission link to be verified according to the data amount of the variable data of one transmission.

[0086] If the data volume of the variable data in one transmission is less than the specified threshold, the embodiment preferentially enables the transmission link A to transmit the variable data in order to reduce the cost and save time as much as possible. Conversely, if the data volume of the variable data in one transmission is greater than the specified threshold, the transmission link B is enabled to transmit the variable data.

[0087] The determining module is configured to verify the selected transmission link and determine whether the verification is passed.

[0088] Before the verification, the method further comprises determining the corresponding bandwidth of the virtual nodes in the transmission link.

[0089] The bandwidth of the virtual node refers to the data volume that the virtual node can transmit in a unit of time. For example, in a data center of a cloud service provider, the bandwidth of the virtual node determines how fast it can receive and send data.

[0090] In the data transmission process, the bandwidth cannot be fully utilized or the bandwidth performance is reduced due to various factors. For example, in the communication process between nodes, there is theoretically 100 Mbps of bandwidth, but due to various obstacles, the bandwidth that can be effectively utilized may only be 60 Mbps. This will greatly reduce the speed of receiving and sending data.

[0091] Therefore, the embodiment calculates the bandwidth obstacle value of the transmission link according to the bandwidth of the virtual nodes in the transmission link. The bandwidth obstacle value reflects whether the transmission rate of the transmission link can meet the requirements. When the bandwidth obstacle value is less than the specified threshold, it means that the transmission rate of the transmission link can meet the requirements, and the verification is considered to be passed. Conversely, the verification is not passed.

[0092] The bandwidth obstacle value of the transmission link is specifically represented as:

[0093] ;

[0094] Wherein, represents the bandwidth obstacle value of the transmission link x, M represents the number of nodes in the transmission link x, I represents the number of nodes in the transmission link x whose bandwidth is less than the specified threshold, represents the number of times of available bandwidth reduction of the nodes in the transmission link x whose bandwidth is less than the specified threshold in the specified historical time period, represents the number of times of available bandwidth reduction of the remaining nodes in the transmission link x except 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 flow exits.

[0095] As another embodiment, a node adding module is further included. When the transmission verification fails, the node adding module eliminates the node with bandwidth less than a specified threshold and adds a new node.

[0096] Wherein after the addition of the new node is completed, the bandwidth blocking value of the transmission link x after the addition of the new node is confirmed using the above formula, and if the bandwidth blocking value passes, in order to ensure the safety of the transmission and improve the success rate of data transmission, the embodiment further verifies the transmission time of the transmission link x after the addition of the new node.

[0097] Wherein the transmission time is represented as:

[0098] ;

[0099] Wherein represents the time of transmitting data of the transmission link x, Q represents the data amount of the received variable data, L represents the number of nodes of the transmission link x after the addition of the node, represents the bandwidth utilization rate of the node i in the transmission link x, represents the total bandwidth of the transmission link x.

[0100] If the transmission time is greater than a specified threshold, it is considered that the transmission link x after the addition of the node still cannot well complete the data transmission, the verification fails, and the process exits. Otherwise, it is considered that the verification passes, and the data transmission execution unit 240 is executed.

[0101] The data transmission execution unit 240 is configured to use the transmission link that passes the verification to transmit the variable data.

[0102] Wherein taking the transmission link A as an example, if the transmission link A passes the verification, the transmission link A is used to transmit the variable data.

[0103] Specifically, the variable data is input from the virtual root node, the virtual root node sends a transmission request to the virtual intermediate node, the variable data is transmitted to one or more virtual intermediate nodes, the one or more virtual intermediate nodes receive the variable data and send a data transmission request to the virtual leaf node, and the virtual leaf node receives the variable data.

[0105] Wherein after the virtual leaf node receives the variable data, data verification is performed on the variable data after the transmission. In the process of performing the data verification, the variable data is divided into multiple data blocks, and the multiple data blocks are respectively verified.

[0110] wherein each byte in the final face variable information data block, the final serial number data block and the final barcode data block is added (generally ignoring the carry) to obtain a total sum, which is specifically represented as:

[0111] ;

[0112] wherein S represents the byte total sum in the final face variable information data block (or the final serial number data block or the final barcode data block), represents the byte sequence of the final face variable information data block (or the final serial number data block or the final barcode data block), and mod 256 represents a modulo operation.

[0113] wherein the byte total sum of the original face variable information data block (or the final serial number data block or the final barcode data block) is calculated according to the above formula, and the calculated byte total sum is compared with the byte total sum of the original face variable information data block (or the original serial number data block or the original barcode data block), and if they are consistent, it is considered that the data verification is passed, and step S6 is executed. Otherwise, it is considered that the data verification is failed.
