The updated management data of the chain storage is used for mutual disaster recovery backup.

In one embodiment of the invention, each management database node contains a management data chain. The management data chain is implemented by blockchain technology.

For the convenience of the following description, the blockchain technology related to the embodiment of the present application will be explained first.

A blockchain is a distributed database formed by a peer-to-peer (P2P) network. The network includes multiple nodes. Any two nodes are connected to each other. Each node maintains a growing number of nodes. And a chain of blocks arranged in order. Each block contains a timestamp and is connected to a block before it. Depending on the design, the blockchain itself has the property of preventing data from being modified, that is, once the data is recorded in the block, it cannot be returned for modification. With the help of P2P networks and distributed timestamp servers, a blockchain database can be managed automatically. A blockchain is like an open, distributed general ledger that records transaction information efficiently, securely, and permanently.

As shown in FIG. 1A, a blockchain includes a plurality of blocks, and the plurality of blocks form a tree structure having at least one branch, each of which forms a tree structure. The blocks are each a node in the tree structure. The trust path of the blockchain (the path formed by the block identified by the grid box) has the largest number of nodes, starting from the first block (the block identified by the white box) and always connecting to the latest block, the others exist in The path formed by the block outside the trust path (the block identified by the diagonal stripe box) is an invalid path.

A block is a data structure that records transactions, consisting of a block body and a block header. The block body is responsible for recording all transaction information for a period of time. The block header includes: version number, parent block hash value, Merkle root, time stamp, difficulty value, random number. Among them, the Merkle root is a value calculated by the hash value of all the transactions in the block body, which is used to check whether a transaction exists in the block. The timestamp is used to record the generation time of the block. The difficulty value indicates the difficulty target of the block workload proof. The parent block hash value is used to implement the connection between the blocks, and the random number is used to implement the mining mechanism.

Next, the working principle of the blockchain is introduced:

In the blockchain.

(1) Node A uses the private key to sign a digital signature on the last transaction information of the resource to be transferred and the public key of Node B, and attach the signature to the end of the resource to be transferred to obtain a transaction order.

(2) Node A broadcasts the transaction slip in the network.

(3) Each node in the network acquires the right to generate a block according to the transaction order through the mining mechanism, that is, each node verifies the validity of the transaction ticket when the transaction order is detected, and the verification is effective. After that, start solving math problems. The process of solving the problem is: finding a value such that the hash value of the previous block and the hash value calculated by the specified algorithm of the currently received transaction order satisfy the preset condition.

(4) If the node C solves the problem successfully, the block is generated according to the solution and the transaction order, and the generated block is broadcasted in the network.

(5) When the node other than the node C detects the generated block, the validity of the block is verified by the solution in the block, and the block is placed in the block after determining that the block is valid. The end of the longest chain of the chain.

FIG. 4 is a flowchart of a method for storing management data according to an embodiment of the present application. The method is applied to the distributed cloud data center of FIG. 2A. As shown in FIG. 4, the method includes the following steps:

Step 401: The first management database node acquires the updated management data, and stores the updated management data in the management data link of the first area unit, where the first management database node is the first area unit of the plurality of area units. Have a management database node.

The first area unit is any one of the plurality of area units, and the management data link in the area unit is used to store management data, so when the first management database node of the first area unit receives the management data, The updated management data can be stored in its own management data chain.

Specifically, since the management data chain of each area unit includes a plurality of first blocks, each of the plurality of first blocks includes one management data, and the management data chain of each area unit is a tree structure, the plurality of first blocks are respectively nodes in the first tree structure, and therefore, the first management database node can store the updated management data in the management data link of the first area unit. The first management database node generates a new first block, the new first block includes the updated management data, and the first management database node adds the new first block as the first trust path. The last first block, the first trust path having the most nodes in the management data chain of the first area unit.

Since the default trust path in the management data link is the path containing the most nodes in the distributed cloud data center shown in FIG. 2A, when the first management database node of the first area unit is generating the first block, The generated first block may be added to the end of the path with the most nodes in its own management data chain.

In addition, the first management database node of the first area unit obtains the updated management data by: when the management data link of the first area unit acquires the transaction order carrying the management data through the mining mechanism, the transaction order is carried The management data is determined as the updated management data, and the transaction data is generated by the management data link of the second area unit according to the updated management data and broadcasted in the first P2P network, and the second area unit is the first area unit. Any area unit other than .

It should be noted that the transaction ticket broadcasted by the management data link of the second area unit is a transaction ticket after being signed by the private key. Therefore, when the first unit area unit receives the transaction order, the public key verification signature is also required. Validity to determine the validity of the transaction, and after determining that the transaction is valid, perform the step of generating a first block based on the transaction.

Wherein, when the management database node of each regional unit further includes a database cache, the management data chain of the second regional unit generates a transaction order according to the updated management data:

When the user updates the management data through the second area unit, the management system of the second area unit receives multiple configuration requests triggered by the user through a preset operation, and the management system of the second area unit acquires for any one configuration request. The configuration information carried by the configuration request is sent to the service system of the second area unit, and the service system of the second area unit performs the relevant configuration according to the configuration information, and when the implementation is completed, the second area unit is implemented. The management system responds to the configuration result, and the management system of the second area unit writes the configuration information corresponding to the configuration result to the database cache through the database access layer of the second area unit according to the configuration result. When the management system of the second area unit receives the configuration result for all configuration requests, displaying the received configuration result, when receiving the acceptance pass information for the configuration result triggered by the preset operation, determining that the configuration is completed, and Obtaining all configuration information cached in the database cache of the second area unit by the database access layer of the second area unit, and packaging all the acquired configuration information to obtain the management data after the update, and then according to the management data after the update Generate a transaction order and sign the transaction with a private key.

That is, in the embodiment of the present application, the first block in the management data chain is divided according to the granularity of the delivery behavior, and the delivery behavior includes any behavior of updating the management data, for example, the expansion and management of the management data. Data upgrades or modifications to management data.

The preset operation may be a click operation, a selection operation, or a voice operation.

Optionally, when the management database node of each area unit further includes a database cache, the management database node of the first area unit adds the generated first block to the end of the trust path of the management data link of the own area, The obtained management data is cached in the database cache. Specifically, the management data link of the first area unit sends the acquired management data to the database access layer of the first area unit, and the database access layer of the first area unit writes the management data to the database cache of the first area unit.

In addition, the first first block in the management data chain of the first area unit is obtained according to the factory configuration data set by the publisher of the distributed cloud data center. That is, in the initialization state, the management data chain of the first area unit generates the first first block based on the management data at the time of initialization.

The management data at the time of initialization is the factory configuration data set by the publisher of the distributed cloud data center.

Step 402: The first management database node instructs the second management database node to store the updated management data in a management data link of the second area unit, where the second area unit is other than the first area unit among the plurality of area units. Any of the area units, the second area unit has a second management database node, and the management data links of the different area units of the plurality of area units are used for mutual disaster recovery backup.

The first management database node instructs the second management database node to store the updated management data in the management data link of the second area unit, that is, the first management database node instructs the second management database node to The first block is added as the last first block in the second trust path. Specifically, the first management database node implements step 402 by broadcasting: the first management database node of the first area unit broadcasts the generated new first block in the first P2P network, so that the first area unit is The management database node of each of the area units adds the generated new first block to the end of the path of the management node of the management node having the most nodes, wherein the first P2P network is connected to the plurality of area units A network of management data links for each regional unit.

It should be noted that, since each area unit of the distributed cloud data center shares a set of management data, it is necessary to ensure the consistency of data stored in the management data link in each area unit. Therefore, after the management database node of the first area unit generates the new first block, the generated new first block needs to be transmitted in the first P2P network, so that other area units will generate the new one. The first block joins the end of the path with the most nodes of its own management data chain to achieve the purpose of updating the management data chain of other area units.

In the embodiment of the present application, the distributed cloud data center includes a plurality of area units. When the first management database node in the first area unit obtains the updated management data, the management data link in the first area unit stores the The updated management data, and instructing the second management database node to store the updated management data in the management data link of the second area unit. Therefore, in the present application, when the first management database node stores the updated management data, the management database node of the other regional unit will also store the updated management data to implement the management database node of each regional unit. Management data is stored and the stored management data is consistent. That is, in the present application, management data is stored in each area unit, so that each of the area units can acquire management data from its own management data chain, which improves the efficiency of the area unit to obtain management data. In addition, if there is a problem with a certain area unit, since management data is stored in the management data link of each area unit, there is no possibility that other area units cannot obtain management data.

FIG. 5 is a flowchart of another method for storing management data provided in an embodiment of the present application, which is applied to the distributed cloud data center shown in FIG. 2A, and the storage data storage method shown in FIG. 5 is used in FIG. The storage method of the management data shown is further explained. Specifically, as shown in FIG. 5, the method includes the following steps:

Step 501: The first management database node acquires the updated management data, and stores the updated management data in the management data link of the first area unit, where the first management database node is the first area unit of the plurality of area units. Have a management database node.

The implementation of the step 501 is basically the same as the implementation of the step 401 in the embodiment shown in FIG. 4, and will not be described in detail again.

Step 502: The first management database node instructs the second management database node to store the updated management data in the management data link of the second area unit, where the second area unit is other than the first area unit of the plurality of area units. Any of the area units, the second area unit has a second management database node, and the management data links of the different area units of the plurality of area units are used for mutual disaster recovery backup.

The implementation of step 502 is basically the same as the implementation of step 402 in the embodiment shown in FIG. 4, and will not be elaborated in the same time.

The above steps 501 to 502 are used to explain the process of generating the management data chain of a certain area unit of the distributed cloud data center shown in FIG. 2A. The following step 503 is used to explain how to read management data from the management data link of a regional unit of the distributed cloud data center.

Step 503: The first management database node of the first area unit receives the management data read request, and reads the management data in the block at the end of the trust path of the management data link of the own.

Step 503 can be implemented by the following steps 5031 to 5033:

Step 5031: When the service system of the first area unit receives the management data read request, forward the management data read request to the management system of the first area unit.

The management data read request is triggered by the user. The distributed cloud data center shown in FIG. 2A or FIG. 2B knows that the service system of each regional unit is not connected to the management database node, but is each The management system of the area unit is connected to the management database node. Therefore, when the service system of the first area unit receives the management data read request, the management data read request needs to be forwarded to the management system of the first area unit.

Step 5032: The management system of the first area unit acquires management data from the first management database node of the first area unit.

Specifically, the implementation of step 5032 is: when the management system of the first area unit receives the management data read request, the management system of the first area unit sends a management data request message to the database access layer of the first area unit, The database access layer of the first area unit receives the management data request message, and determines the management data according to the management data link of the first area unit, and the database access layer of the first area unit transmits the determined management data to the management system of the first area unit.

Optionally, when the management database node of each area unit further includes a database cache, the management database node of the first area unit reads the management data in the generated first block of the end of the trust path of the management data link of the first area unit. Previously, the management database node of the first area unit determines whether the management data is stored in its own database cache, and if so, the first management database node of the first area unit obtains the management data from its own database cache, and if not, the first The first management database node of a zone unit performs the step of reading the management data in the first block generated at the end of the path of the management node of the own management data chain.

Specifically, before the database access layer of the first area unit determines the management data according to the management data link of the first area unit, it may first determine whether the management data is stored in the database cache of the first area unit, and if so, from the first area. The management data is obtained in the database cache of the unit; if not, the step of determining the management data according to the management data link of the first area unit and the change audit data chain is performed.

That is, the management system of the first area unit acquires management data through the database access layer of the first area unit, and the database access layer of the first area unit determines the database cache before acquiring the management data from the management data link. Whether the management data is stored to improve the efficiency of obtaining the management data. If the database access layer of the first area unit does not obtain the management data from the database cache of the first area unit, the management data is obtained from the management data link.

The implementation manner of determining the management data by the database access layer of the first area unit according to the management data link of the first area unit may be: the database access layer of the first area unit forwards the management data to the management data link of the first area unit. Requesting, when the management data link of the first area unit receives the management data read request, the management data link of the first area unit searches for the first block of the end of the path with the most nodes, and the first block from the search The management data is acquired in the block, and the management data link of the first area unit sends the acquired management data to the database access layer of the first area unit.

Step 5033: The management system of the first area unit sends the acquired management data to the service system of the first area unit.

When the management system of the first area unit receives the management data sent by the database access layer of the first area unit, the management system of the first area unit sends the received management data to the service system of the first area unit to complete the reading. The process of managing data.

The foregoing step 503 is used to explain how to read the management data from the cloud distributed data center shown in FIG. 2A. In actual application, if a certain regional unit of the distributed cloud data center fails, the regional unit may be caused. There is also a problem with managing the data link, in which case the management data link for the regional unit needs to be restored. The following step 504 is used to explain how to recover the management data link of the area unit.

Step 504: After the first regional unit fails to cause a problem in its management data link, the first management database node of the first regional unit receives the data recovery request, and rejoins its management data link to the first P2P network, and The block information is reloaded in the first P2P network, and a data recovery confirmation message is returned.

Specifically, step 504 can be implemented by the following steps:

(1) After the failure of the first area unit, when the management system of the first area unit receives the data recovery request, the data recovery request is sent to the database access layer of the first area unit, and the data recovery request is used to indicate the reloading The data link is managed, and the database access layer of the first area unit receives the data recovery request and sends a network join request to the management data link of the first area unit.

The data recovery request is triggered by the administrator by a preset operation, that is, after the first area unit fails, when the manager needs to restore the first area unit, the data recovery request may be triggered by a preset operation.

In addition, since the management data link of the first area unit may not be in the first P2P network when the first area unit fails, the management data link of the first area unit is first added to the first area through the network join request. The P2P network to recover the block data in the management data link of the first area unit.

(2) The management data link of the first area unit receives the network join request, rejoins the first P2P network, and reloads the block information from the first P2P network, and after obtaining each of its own blocks, the first area unit The database access layer sends a first network join confirmation message.

The management data link of the first area unit receives the network join request, and the method of rejoining the first P2P network is: the management data link of the first area unit broadcasts a network join request in the first P2P network, and the network join request Carrying the identity information of the first area unit, when the other area units in the first P2P network receive the network join request, verify the identity information of the first area unit, and broadcast the verification result to determine whether to allow the first The zone unit joins the first P2P network.

The implementation manner of reloading the block information from the first P2P network by the first area unit may be: the management data link of the first area unit sends a management data link acquisition request to the management data link of any other area unit in the first P2P network. When the management data link of the other area unit receives the management data link acquisition request, the block in the chain of the first area unit is sent to the management data link of the first area unit, so that the management data link of the first area unit can obtain each Block.

(3) The database access layer of the first area unit receives the first network join confirmation message and transmits a data recovery confirmation message to the management system of the first area unit.

When the database access layer of the first area unit receives the first network join confirmation message sent by the management data link of the first area unit, determining that the data of the management data link of the current first area unit is restored, therefore, the first area unit The database access layer may send a data recovery confirmation message to the management system of the first regional unit.

Further, when the management database node of each regional unit further includes a database cache, when the first regional unit fails, the stored management data in the database cache of the first regional unit may have expired, and therefore, when the first region When the data in the management data link of the unit is restored, the latest management data can be re-stored in the database cache of the first area unit.

Specifically, the database access layer of the first area unit determines whether management data is stored in the database cache of the first area unit, and if not, determines management data according to the management data link of the first area unit, and writes the determined management data. Enter the database cache of the first zone unit.

The database access layer of the first area unit has been explained in detail in step 504 according to the management data link of the first area unit and the determination management data, and the description will not be repeated here.

FIG. 6 is a flowchart of another method for storing management data according to an embodiment of the present disclosure. The method is applied to the distributed cloud data center of FIG. 2B. As shown in FIG. 6, the method includes the following steps:

Step 601: The first management database node of the first area unit acquires the updated management data, and generates a new first block according to the updated management data, where the first area unit is any one of the plurality of area units. unit.

The new first block is generated according to the updated management data, that is, the generated new first block includes the updated management data. In addition, the implementation manner of obtaining the updated management data by the first management database node and the implementation manner of generating the new first block have been explained in detail in the steps in the embodiment of FIG. 4, and will not be further explained herein.

Step 602: The first management database node of the first area unit stores the generated first block.

In the embodiment of the present application, the trust path of the management data link is no longer the default path with the most nodes, but the specified trust path. Therefore, when the first management database node of the first area unit generates the first block, After that, the current first trust path needs to be determined by changing the audit data chain, and the first block is added to the end of the first trust path in its own management data chain.

Specifically, the implementation of step 602 is: the first management database node determines the first trust path according to the third trust path in the change audit data chain of the first area unit, and the change audit data of the third trust path in the first area unit There are the most nodes in the chain and the new first block is added as the last first block in the first trust path.

It should be noted that, in the embodiment of the present invention, the information of the current trust path in the data chain of the audit management chain is changed, and the credibility of the information of the audit chain itself is still determined by the method of trusting only the path with the most nodes. And the operation of writing the trust path is completed internally by the system, thereby effectively ensuring the credibility of the trust path information. That is, the third trust path has the most nodes in the change audit data chain of the first area unit.

That is, in the embodiment of the present invention, the trust path information in the management data chain is recorded by changing the blocks in the audit data chain. Therefore, before the management data link of the first area unit adds the generated first block to the end of its own trust path, the management data link of the first area unit determines the first area unit through the database access layer of the first area unit Change the end block of the path with the most nodes in the audit data chain, and determine its own trust path according to the end block of the path with the most nodes in the audit data link of the first area unit.

Specifically, the first management database node may determine that the first trust path is implemented according to the third trust path in the change audit data link of the first area unit, that the management data link of the first area unit may be to the first area unit. The database access layer sends a trust path read request, and when the database access layer of the first area unit receives the trust path read request, the trust path read request is sent to the change audit data chain of the first area unit. When the change audit data link of the first area unit receives the trust path read request, the second block of the end of the path with the most nodes is determined from the second block at the end of the path with the most nodes. Obtaining an identifier of the first block at the end of the trust path in the management data chain of the first area unit, and transmitting the acquired identifier of the first block to the database access layer of the first area unit. The database access layer of the first area unit transmits the received identifier of the first block to the management data chain of the first area unit. When the management data link of the first area unit receives the identifier of the first block, the identifier of the end block is searched from the data link of the first area as the path of the identifier of the first block, and the found path is determined as The first trust path.

Optionally, when the management database node of each area unit further includes a database cache, the management database node of the first area unit adds the generated first block to the end of the first trust path of the management data link of the own area, The received management data can also be cached in the database cache. Specifically, the management data link of the first area unit transmits the received management data to the database access layer of the first area unit, and the database access layer of the first area unit writes the management data to the database cache of the first area unit.

In addition, the first first block in the management data chain of the first area unit is obtained according to the factory configuration data set by the publisher of the distributed cloud data center. That is, in the initialization state, the management data chain of the first area unit generates the first first block based on the management data at the time of initialization. And the management data link of the first area unit sends a second update request to the change audit data link of the first area unit by using the database access layer of the first area unit, and the change audit data link of the first area unit receives the second update request, and A first second block is generated, and the first second block is used to indicate that the end block of the trust path in the management data chain of the first area unit is the first first block.

In addition, after the first data block of the first area unit adds the generated first block at the end of the trust path, it indicates that the first block of the end of the first trust path in the current management data chain has changed, and therefore needs to be changed. The audit data link is updated. Specifically, the management data chain may generate a first update request and implement an update to the change audit data chain by the following step 603 according to the first update request.

Step 603: The first management database node of the first area unit sends a first update request to its own change audit data link, and adds a second block at the end of the path with the most nodes in the change audit data link of its own. The second block is used to indicate that the end block of the trust path in the management data chain of the first area unit is the generated first block.

Specifically, the implementation of the step 603 may be: the management data link of the first area unit sends a first update request to the database access layer of the first area unit, where the first update request carries the first block generated in step 601. Logo. When the database access layer of the first area unit receives the first update request, the first update request is sent to the change audit data chain of the first area unit. The change audit data link of the first area unit receives the first update request, and adds a second block in the path that has the most node, and the currently added second block is used to indicate the management data of the current first area unit. The end block of the trust path in the chain is the first block generated.

Because the first update request carries the identifier of the first block generated in step 601, when the change audit data link of the first area unit receives the first update request, according to the first area carried in the first update request The identifier of the block generates a second block, and the generated second block is added to the end of the path having the most nodes, and the generated second block stores the identifier of the first block generated in step 601.

Step 604: The first management database node of the first area unit broadcasts the generated first block in the first P2P network, so that the management database node of each area unit except the first area unit will generate The first block is added to the end of the trust path of its own management data link, and the management database node of each area unit other than the first area unit adds a second in the path with the most nodes in the change audit data link. Block.

It should be noted that, since each area unit of the distributed cloud data center shares a set of management data, it is necessary to ensure the consistency of the management data link in each area unit and the data stored in the change audit data link. Therefore, after the management data link of the first area unit generates the first block, the generated first block needs to be transmitted in the first P2P network, so that the other area units update their management data link according to step 604. Change the audit data chain.

Wherein, the change audit data link of the other area unit adds the second block in the path with the most nodes and the change audit data link of the first area adds the second in the path with the most nodes of the own area. The implementation of the blocks is basically the same and will not be elaborated here.

In the embodiment of the present application, the distributed cloud data center includes a plurality of regional units, and the management database nodes of each regional unit include a management data link and a change audit data link. When the first area unit obtains the updated management data, generates a first block according to the updated management data, and determines a first trust path of the management data chain according to the change audit data chain, and then according to the first trust path. The first block is stored in the management data chain. Thereafter, the management database node of the first area unit broadcasts the generated first block in the first P2P network, so that the management database node of each area unit other than the first area unit will generate the first block Join the end of the trust path of your own management data link. That is, in the embodiment of the present application, management data is stored in each area unit, so that each of the area units can obtain management data from its own management data chain, thereby improving the efficiency of obtaining the management data by the area unit. . In addition, if there is a problem with a certain area unit, since management data is stored in the management data link of each area unit, there is no possibility that other area units cannot obtain management data.

FIG. 7 is a flowchart of another method for storing management data according to an embodiment of the present application, which is applied to the distributed cloud data center shown in FIG. 2B, and the method for storing management data shown in FIG. 7 is used for FIG. 6 The method of storing management data is further illustrated. Specifically, as shown in FIG. 6, the method includes the following steps:

Step 701: The first management database node of the first area unit acquires the updated management data, and generates a first block according to the updated management data, where the first area unit is any one of the plurality of area units.

The implementation manner of step 701 is basically the same as the implementation manner of step 601 in the embodiment shown in FIG. 6, and will not be elaborated in the same time.

Step 702: The first management database node of the first area unit stores the generated first block.

The implementation of step 702 is basically the same as the implementation of step 602 in the embodiment shown in FIG. 6, and will not be described in detail again.

Step 703: The first management database node of the first area unit sends a first update request to its own change audit data link, and adds a second block to the end of the path with the most nodes of its own change audit data link. The second block is used to indicate that the end block of the trust path in the management data chain of the first area unit is the generated first block.

The implementation manner of step 703 is basically the same as the implementation manner of step 603 in the embodiment shown in FIG. 6, and will not be elaborated in the same time.

Step 704: The first management database node of the first area unit broadcasts the generated first block in the first P2P network, so that the management database node of each area unit except the first area unit will generate The first block is added to the end of the trust path of its own management data link, and the management database node of each area unit other than the first area unit is added to the path with the most nodes in the change audit data chain. Second block.

The implementation of step 704 is basically the same as the implementation of step 604 in the embodiment shown in FIG. 6, and will not be elaborated in the second.

The above steps 701 to 704 are used to explain how to determine the management data link and change audit data chain of each area unit, that is, to explain the management data chain and change audit data link write management to each area unit. The process of data. The following is a description of the management data link of the regional unit and the application of the change audit data link. Among them, the application of the management data link and the change audit data link for the regional unit include the following two aspects:

(1) How to read management data from the management data link of the regional unit and the change audit data link;

(2) How to recover management data according to the management data link of the regional unit and the change audit data link.

Wherein, the following step 705 is used to explain how to read the management data from the management data link of the regional unit and the change audit data chain, and the following

steps

706 and 707 are used to explain how to manage the data link and change according to the regional unit. The audit data link performs management data recovery.

Step 705: Acquire management data when the first management database node of the first area unit receives the management data read request.

In the embodiment of the present application, the first management database node of the first area unit receives the management data read request, and determines the end block of the path with the most nodes in the change audit data chain of the first area unit, and the first area of the first area unit The management database node determines the trusted road hole in the management data chain according to the end block of the path with the most nodes in the audit data chain of the change, and the first management database node of the first area unit has its own management data link. The first block at the end of the path of the most node reads the management data. That is, the first management database node determines the first trust path according to the third trust path, and reads the management data in the last first block in the first trust path.

Specifically, the foregoing process may be implemented by the following steps 7051 to 7053:

Step 7051: When the service system of the first area unit receives the management data read request, forward the management data read request to the management system of the first area unit.

The management data read request is triggered by the user, and the distributed cloud data center shown in FIG. 2B knows that the service system of each regional unit is not connected to the management database node, but by each regional unit. The management system is connected to the management database node. Therefore, when the service system of the first area unit receives the management data read request, the management data read request needs to be forwarded to the management system of the first area unit.

Step 7052: The management system of the first area unit acquires management data from the management database node of the first area unit.

Specifically, the implementation of step 7052 is: when the management system of the first area unit receives the management data read request, the management system of the first area unit sends the management data read to the database access layer of the first area unit. Requesting, the database access layer of the first area unit receives the management data read request, and determines management data according to the management data link of the first area unit and the change audit data chain, and the database access layer of the first area unit is directed to the first area unit The management system sends the determined management data.

Further, when the management database node of each regional unit further includes a database cache, before the database access layer of the first regional unit determines the management data according to the management data link of the first regional unit and the change audit data chain, the first Whether the management data is stored in the database cache of the area unit, and if so, the management data is obtained from the database cache of the first area unit; if not, the management data chain and the change audit data chain according to the first area unit are determined to be managed. The steps of the data.

That is, the management system of the first area unit acquires management data through the database access layer of the first area unit, and the database access layer of the first area unit obtains management data from the management data link and the change audit data chain. First, it is determined whether the management data is stored in the database cache to improve the efficiency of obtaining the management data. If the database access layer of the first area unit does not obtain the management data from the database cache of the first area unit, then the management data link is Obtain management data in the change audit data chain.

The implementation manner of determining the management data by the database access layer of the first area unit according to the management data link of the first area unit and the change audit data link may be: changing the audit data of the database access layer of the first area unit to the first area unit. The chain sends a trust path read request, the change audit data link of the first area unit receives the trust path read request, and searches for the end second block of the path with the most nodes, and the change audit data chain of the first area unit is based on Finding the second block, determining an identifier of the first block at the end of the trust path of the management data link of the first area unit, and transmitting the identifier of the first block at the end of the trust path to the first area unit a database access layer, the database access layer of the first area unit sends the identifier of the first block at the end of the trust path to the management data link of the first area unit, and the management data link of the first area unit is based on the end of the trust path The identifier of a block finds the corresponding first block, and obtains management data from the first block found, Area management data link means transmits the acquired management data to the database access unit layer of the first region.

That is, the database access layer of the first area unit first determines the trust path in the management data of the first area unit through the change audit data chain of the first area unit, and then obtains the management from the management data link according to the determined trust chain. Data to ensure the credibility of the acquired management data.

Step 7053: The management system of the first area unit sends the acquired management data to the service system of the first area unit.

Step 706: After the first regional unit fails to cause a problem in its management data link, when the first management database node of the first regional unit receives the first type of data recovery request, the first management database node of the first regional unit Perform data recovery.

That is, after the first regional unit fails to cause a problem in its management data link, the first management database node of the first regional unit receives the first type of data recovery request, and rejoins its own management data link to the first P2P network. Reloading the block information from the first P2P network, and rejoining the change audit data link of the first P2P network to the second P2P network, reloading the block information from the second P2P network, and the first management database node of the first area unit Returns a data recovery confirmation message.

Specifically, the above process can be implemented by the following steps:

(1) after the failure of the first area unit, when the management system of the first area unit receives the first type of data recovery request, the first type of data recovery request is sent to the database access layer of the first area unit, first The class data recovery request is used to indicate that the management data link is reloaded and the audit data chain is changed. The database access layer of the first area unit receives the first type of data recovery request, and respectively manages the data link to the first area unit and changes the audit data link. Send a network join request.

The first type of data recovery request is triggered by a preset operation by the administrator, that is, after the first area unit fails, when the manager needs to restore the first area unit, the first operation may be triggered by a preset operation. Class data recovery request.

In addition, since the management data link and the change audit data link of the first regional unit may no longer be in the first P2P network and the second P2P network, the first regional unit may be added to the first P2P network and the second P2P network. The management data link and the change audit data link of a regional unit are rejoined to the first P2P network and the second P2P network to restore the management data link of the first area unit and change the block data in the audit data chain.

(2) The management data link of the first area unit receives the network join request, rejoins the first P2P network, and reloads the block information from the first P2P network, and after obtaining each of its own blocks, the first area unit The database access layer sends a first network join confirmation message, and the change audit data link of the first area unit receives the network join request, rejoins the second P2P network, and reloads the block information from the second P2P network, and obtains each of its own The block sends a second network join confirmation message to the database access layer of the first area unit.

The manner in which the first area unit reloads the block information from the second P2P network may be: the change audit data link of the first area unit sends the change audit data to the change audit data link of any other area unit in the second P2P network. The chain acquisition request, when the change audit data link of the other area unit receives the change audit data link acquisition request, sends the block in the chain of the first area unit to the change audit data chain of the first area unit, so that the first area unit Each block can be obtained by changing the audit data chain.

(3) The database access layer of the first area unit receives the first network join confirmation message and the second network join confirmation message, and sends a data recovery confirmation message to the management system of the first area unit.

When the database access layer of the first area unit receives the first network join confirmation message sent by the management data link of the first area unit and the second network join confirmation message sent by the change audit data link of the first area unit, determining the current The management data link of the first area unit and the data in the change audit data chain are restored. Therefore, the database access layer of the first area unit can transmit a data recovery confirmation message to the management system of the first area unit.

Further, when the management database node of each regional unit further includes a database cache, when the first regional unit fails, the stored management data in the database cache of the first regional unit may have expired, and therefore, when the first region When the management data link of the unit and the data in the change audit data link are restored, the latest management data can be re-stored in the database cache of the first area unit.

Specifically, the database access layer of the first area unit determines whether management data is stored in the database cache of the first area unit, and if not, determines management data according to the management data link of the first area unit and the change audit data link, and The determined management data is written into the database cache of the first area unit.

The database access layer of the first area unit determines the management data according to the management data link of the first area unit and the change audit data link. The detailed description is in step 705, and the description is not repeated here.

For the convenience of description, the process of restoring the management data link and the change audit data link in the management database node in the first area is referred to as the first type of data recovery. In addition, the first type of data recovery may be applied to the disaster recovery and back-cutting process, or may be applied to a scenario where the device or system corresponding to the area unit fails and the locally stored management data is damaged.

The following step 707 is used to introduce the second type of data recovery provided by the embodiment of the present application, and the second type of data recovery is applied to a logic error scenario. The logical error scenario refers to a scenario in which the management data is configured to an incorrect value according to a normal configuration process due to an intentional or unintentional error. In this scenario, since the configuration process is normal, the current valid data of all the regional units is configured. Wrong data. In this scenario, in order to restore the correct data, it is necessary to recover from a certain correct time in the history, which can be implemented by the following step 707.

Step 707: When the first management database node of the first area unit receives the second type data recovery request, the first management database node of the first area unit performs data recovery, and the second type of data recovery request is used to indicate that the time is to be specified. The management data is determined to be valid management data.

The implementation manner of the data recovery by the management database node of the first area unit may be: the first management database node acquires the specified time carried in the data recovery request, and the first management database node is in the first area unit according to the specified time Querying, in the data link, a first block whose query timestamp matches the specified time, the first management database node generates a new second block according to the first block found, and adds the new second block And being the last second block in the third trust path, the new second block is configured to reset the first trust path according to the first block that is found.

Specifically, when the management system of the first area unit receives the second type of data recovery request, the second type of data recovery request is sent to the database access layer of the first area unit, and the database access layer of the first area unit is according to the specified time And querying, from the management data link of the first area unit, the first block whose timestamp matches the specified time, and the database access layer of the first area unit changes the audit data to the first area unit according to the first block that is found. The chain sends a trust path reset request, the change audit data link of the first area unit receives the trust path reset request, and adds a second block at the end of the path with the most nodes, and the currently added second block The end block for indicating the trust path of the current management data link is the first block of the search, and the change audit data chain of the first area unit sends a trust path reset confirmation message to the database access layer of the first area unit, first The database access layer of the regional unit receives the trust chain reset confirmation message and sends data recovery to the management system of the first regional unit Confirmation message.

The database access layer of the first area unit queries the first block that matches the timestamp and the specified time from the management data link of the first area unit according to the specified time: the database access layer direction of the first area unit The management data link of the first area unit sends a block query request, and the block query request carries the specified time. When the management data link of the first area unit receives the block query request, according to the specified time from the chain of the own And searching for the first block whose timestamp matches the specified time, and sending the identifier of the found first block to the database access layer of the first area unit.

At this time, the database access layer of the first area unit carries the identifier of the first block that is found to the trust path reset request sent by the change audit data link of the first area unit, so that the change of the first area unit is audited. The data chain stores the identity of the first block into the newly added second block.

Further, since the current valid data of all the regional units is configured as erroneous data in the second type of data recovery, the change audit data link of the first regional unit adds one at the end of its own path with the most nodes. After the second block, the change audit data link of the first area unit broadcasts the currently added second block in the second P2P network, so that each area unit except the first area unit will be newly added. The second block is added to the end of the path with the most nodes of its own change audit data chain to enable reconfiguration of valid data for all area units.

Wherein, when the management database node of each area unit further includes a database cache, when the second type of data recovery is performed, it indicates that the data stored in the current database cache is also erroneous data, and therefore, the database access layer of the first area unit Before sending the data recovery confirmation message to the management system of the first area unit, the management data in the first block found may also be determined, and the determined management data is written into the database cache of the first area unit, so that the first The management data in the database cache of the zone unit is updated.
