Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture of a node control system 1000 according to an embodiment of the present application, which includes a block chain system 100 and a node control device 200.

The blockchain system 100 refers to a system for data sharing between nodes, and the blockchain system may include a plurality of nodes 101, and the plurality of nodes 101 may refer to respective clients in the blockchain system. Each node 101 may receive input information and maintain shared data within the blockchain system based on the received input information while operating normally. In order to ensure the information intercommunication in the blockchain system, information connection can exist between each node in the blockchain system, and the nodes can transmit information through the information connection. For example, when an arbitrary node in the blockchain system receives input information, other nodes in the blockchain system acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all nodes in the blockchain system are consistent.

Each node in the blockchain system has a corresponding node identifier, and each node in the blockchain system can store node identifiers of other nodes in the blockchain system, so that the generated block can be broadcast to other nodes in the blockchain system according to the node identifiers of other nodes. Each node may maintain a node identifier list as shown in the following table, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an IP (Internet Protocol) address and any other information that can be used to identify the node, and table 1 only illustrates the IP address as an example.

As shown in fig. 2, each node in the blockchain system according to the embodiment of the present application is deployed with one or more services, each node further includes an agent module and one or more blockchains, and each node realizes a function corresponding to each service by starting a service process corresponding to each service.

The agent module is used for communicating with the node control equipment. Specifically, the agent module may be configured to receive a control instruction of the node control device, and execute an operation corresponding to the control instruction. The agent module may be further configured to send the operation state information of each service to the node control device.

Each node in the blockchain system stores one identical blockchain. The block chain is composed of a plurality of blocks, referring to fig. 3, the block chain is composed of a plurality of blocks, the starting block includes a block header and a block main body, the block header stores an input information characteristic value, a version number, a timestamp and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the input information in the block is ensured.

Therefore, the contents in the blocks in the blockchain are related, and the same blockchain is stored in each node of the blockchain system, so that once the blocks in the blockchain are created, the contents in the blocks cannot be modified, and the security of the data in the blocks in the blockchain can be ensured.

And each node realizes the function corresponding to each service by starting the service process corresponding to each service. Each service process is used for realizing the business function corresponding to each service process by utilizing the one or more blockchains. For example, if a node device in the blockchain system deploys a shared ledger service, the shared ledger service may be provided by starting a shared ledger service process corresponding to the shared ledger service. The shared account book service process can utilize the block chain to read and write data, and the function of sharing the account book is realized. One node device in the blockchain system can deploy a plurality of services, and one node device can run service processes corresponding to the plurality of services, for example, a node in the blockchain system can run a digital asset service process corresponding to the digital asset service and a supply chain financial service process corresponding to the supply chain financial service. The node may then implement digital asset service functions and supply chain financial service functions to provide digital asset services and supply chain financial services to the user.

Thus, when a user needs to process data by using the block chain to realize certain functions, the corresponding functions can be realized by calling a service process in the node equipment. Therefore, more functions can be realized by using the block chain, and the block chain technology is more fully utilized.

Referring to fig. 4, fig. 4 is a schematic diagram of a hardware structure of a node control device 200 according to an embodiment of the present disclosure. The node control device 200 includes a processor 201, a memory 202, a communication interface 203, and one or more programs stored in the memory 202 and configured to be executed by the processor 201, the programs including instructions to perform the steps of the node control method of any of the following embodiments. Memory 202 includes Random Access Memory (RAM), and disk storage. The communication interface 203 may optionally include a standard wired interface, a wireless interface (e.g., WI-FI interface).

501. the node control equipment acquires a service control request triggered by a user, wherein the service control request comprises state adjustment information of a target service in a block chain network.

The service control request is used for requesting the node control equipment to adjust the running state of the target service according to the state adjustment information, and the target service is used for realizing the service function corresponding to the target service by using the block chain in the block chain network. Specifically, the node with the target service deployed can run a target service process corresponding to the target service when the target service is in an open state, and the target service process reads and writes data by using a block chain to realize a business function corresponding to the target service. For example, a node deployed with a digital asset service can run a digital asset service process corresponding to the digital asset service when the running state of the digital asset service is an open state, and the digital asset service process reads and writes data by using a block chain, so that a digital asset service function is realized, and the digital asset service is provided for a user.

The user may trigger the service control request through a first target page provided by the node control device. The terminal accesses a first target page provided by the node control device, the first target page displays the working state information of a plurality of services, the first target page also provides a state switch of each service, and a user can select and change the working state corresponding to one of the services by operating the terminal to realize triggering of a service control request for starting the service or triggering of a service control request for closing the service. The service control request is used for requesting the node control device to adjust the running state of the target service according to the state adjustment information.

For example, as shown in fig. 6, the terminal accesses the first target page 600, the first target page 600 includes a plurality of pull-down

controls

601 and 604, and the user can cause the first target page 600 to display the service states of the services through the pull-down controls, and perform state selection, for example, when the user clicks the pull-down control 601, the state types of the service a, including opening and closing, can be displayed, and when the user selects opening, a service control request for starting the service is triggered.

In an alternative embodiment, the user may trigger the service control request through a second target page provided by the node control device. The second target page displays the working state information of a plurality of services, the second target page also provides a state switch of each service, and a user can select and change the working state corresponding to one or more services through an operation terminal and submit the selection result after selecting the working state of one or more services so as to trigger a service control request. In this embodiment, the service control request may include state adjustment information for one or more target services. The service control request is used for requesting the node control device to adjust the working state of each target service in the one or more target services according to the state adjustment information. Therefore, the user can manage the working states of a plurality of services in batch through the node control equipment, and the user operation is more convenient. The state adjustment information includes, for example: adjusted to an on state or adjusted to an off state.

For example, as shown in the example of FIG. 7, the terminal accesses the second target page 700, and the first target page 700 includes a plurality of pull-down

controls

701 and 704, and a submit control 705. The user can make the first target page 700 display the working state of each service through the pull-down controls, and select the state, for example, when the user clicks the pull-down control 701, the state type of the service a, including opening and closing, can be displayed, and when the user selects the working state of each service, the user clicks the submit control 705, and then the service control request is triggered.

In yet another alternative embodiment, the selection instruction issued by the user may further include a first target node where a target service whose state needs to be adjusted is located. For example, in the example shown in FIG. 8, the terminal accesses the third target page 800, where the third target page 800 includes a plurality of pull-down

controls

801 and 804, and a submit control 805. The user can make the first target page 800 display the working state of each service on each node through the pull-down controls, and select the working state, for example, if the user clicks the pull-down control 801, the type of the state of the service a on the node 1 can be displayed, including on and off, and if the user selects the working state of the service a on the node 1, and clicks the submit control block 805, the service control request is triggered, and the service control request includes the node identifier of the node 1 and the state adjustment information of the service a.

502. The node device obtains a first target node where a target service is located.

The node device stores a node identifier of each node in the block chain network and service information deployed on each node. Specifically, the service control request includes a service identifier of the target service, and the node device stores a node identifier of each node in the blockchain network and a service identifier of a service deployed on each node. Then, the node device may find a first node identification of a first target node where the target service is found according to the service identification of the target service. When the service control request includes the state adjustment information of the plurality of target services, the node device may also obtain the first node identifier of the first target node where each target service is located according to the above method.

503. And the node equipment sends a service control instruction to the first target node according to the service control request.

Specifically, when the service control request includes state adjustment information of one target service, the node control device sends a service control instruction to a first target node where the target service is located, where the service control instruction includes the state adjustment information of the one target service. The service control instruction is used for instructing the first target node to adjust the working state of the target service according to the state adjustment information.

When the service control request includes state adjustment information for a plurality of target services, the plurality of target services may be deployed on one first target node or may be deployed on a plurality of first target nodes.

When a plurality of target services are deployed on a first target node, the node control device sends a service control instruction to the target node according to the state adjustment information of the plurality of target services, wherein the service control instruction comprises the state adjustment information of the plurality of target services.

When a plurality of target services are deployed on a plurality of first target nodes, the node control equipment generates a service control instruction corresponding to each first target node according to the state adjustment information of the plurality of target services, wherein each service control instruction comprises state adjustment sub-information of the target service on the first target node corresponding to the service control instruction; and the node control equipment sends each service control instruction to a first target node corresponding to the service control instruction, wherein each service control instruction is used for indicating the corresponding first target node and adjusting the working state of the target service on the first target node according to the state adjustment sub-information.

For example, the plurality of target services are

target services

1, 2, 3, 4, the

target services

1, 2 are deployed on a first target node a, and the target services 3, 4 are deployed on a first target node B. The node control device generates a service control instruction a of the first target node a and a service control instruction B of the first target node B according to the state adjustment information of the

target services

1, 2, 3, 4, wherein the service control instruction a includes state adjustment sub-information of the

target services

1, 2, and the service control instruction a is used for instructing the first target node a to adjust the working states of the

target services

1, 2 according to the state adjustment sub-information of the

target services

1, 2; the service control instruction B includes the status adjustment sub information of the target service 3, 4, and the service control instruction B is used to instruct the first target node B to adjust the working status of the target service 3, 4 according to the status adjustment sub information of the target service 3, 4.

Further, a secure channel is established between the node control device and the first target node, and the node control device sends a service control instruction to the first target node through the secure channel.

Specifically, key negotiation is performed in advance between the node control device and each node of the blockchain system, and a data encryption mode and a corresponding decryption mode are agreed. The node control equipment can encrypt the service control instruction by using an appointed data encryption mode, the encrypted service control instruction is sent to a first target node in the block chain system, and the first target node decrypts the received service control instruction by using an appointed decryption mode to obtain the decrypted service control instruction.

504. The first target node receives the service control instruction and adjusts the operation according to the service control instruction

An operational status of a target service on a first target node.

The service control instruction may be a data stream, and after receiving the service control instruction, the agent module of the first target node converts the service control instruction into an executable file and executes the executable file, thereby changing the working state of the first target service. For example, when the state adjustment information of the target service 1 is adjusted to be in the open state, the agent module may run the service process corresponding to the target service 1 according to the service control instruction, so as to adjust the working state of the first target node 1 to be in the open state. When the state adjustment information of the target service 1 is adjusted to be in the closed state, the agent module may end the service process corresponding to the target service 1 according to the service control instruction, so as to adjust the working state of the first target node 1 to be in the closed state.

In the node control method of the embodiment of the application, a node control device first acquires a service control request triggered by a user, wherein the service control request comprises state adjustment information of a target service in a block chain network, and then acquires a first target node where the target service is located; and then sending a service control instruction to the first target node according to the service control request, wherein the service control instruction is used for instructing the first target node to adjust the working state of the target service deployed on the first target node. Therefore, one or more services are deployed on the nodes of the block chain system, and a user can control the working state of each service through the node control equipment and realize corresponding business functions by utilizing the one or more services. Therefore, more functions can be realized by using the block chain, the block chain technology is more fully utilized, and a user can more conveniently control each node in the block chain network.

Referring to fig. 9, the node control method according to the embodiment of the present application further includes the following steps:

901. one or more second target nodes send load information of the one or more second target nodes to the node control equipment;

the second target node may be any one of the nodes in the blockchain system. The second target node may be the same as or different from the first target node. And the agent module of the second target node monitors the load information of the second target node and sends the load information to the node control equipment. Specifically, the agent module may send the load information of the second target node to the node control device at preset time intervals, or may send the load information of the second target node to the node control device after receiving a load information acquisition request sent by the node control device.

902. And the node control equipment judges whether the overload node exists in the one or more second target nodes according to the load information of the one or more second target nodes.

The load information may be, for example, the occupancy of the CPU, and/or GPU, and/or memory resources. The node control device may compare the load value in the load information with a preset load threshold, and when the load value exceeds the load threshold, determine that the second target node corresponding to the load information is an overloaded node. For example, if the load information includes the CPU occupancy, the CPU occupancy may be compared with a preset CPU occupancy threshold, and when the CPU occupancy exceeds the CPU occupancy threshold, it is determined that the second target node corresponding to the load information is an overloaded node.

903. The node control device obtains the historical running time of one or more overload service processes running on the overload node.

Specifically, the node control device may obtain a historical operating time of one or more overload service processes running on the overloaded node within a preset time period. The preset period of time may be, for example, within a month or within a week, etc. This accurately reflects the latest enablement of each load service.

The node device can send a process running time acquisition request to the agent module, wherein the running time acquisition request comprises process identifications of one or more service-bearing processes, and the agent module feeds back the running time of one or more service-bearing processes to the node control device according to the process identifications.

904. And the node control equipment selects one or more service processes to be finished from one or more overload service processes according to the overload capacity and the historical running time of each overload service process.

Specifically, the node control device obtains a plurality of selectable process groups according to the overload capacity, each selectable process group comprises one or more overload service processes, and the total process load of the one or more overload service processes of each selectable process group is greater than or equal to the load capacity; selecting a first selectable process group with a preset number of groups and the minimum total operation time from the plurality of selectable process groups, wherein the total operation time of each selectable process group is the sum of the historical operation times of one or more overload service processes in the selectable process groups; and then selecting a target selectable process group with the least number of the overload service processes from the first selectable process groups of the preset number groups, and taking one or more overload service processes in the target selectable process group as the service processes to be ended.

For example, when the load information sent by the second target node includes that the CPU occupancy rate is 90% and the load threshold is 75%, the sequence from short to long according to the historical operation duration is obtained, the overloaded service processes running on the second target node are service processes 5, 6, 7, 8, and 9, the CPU occupancy rate of the service process 5 is 7%, the CPU occupancy rate of the service process 6 is 3%, the CPU occupancy rate of the service process 7 is 5%, the CPU occupancy rate of the service process 8 is 10%, and the CPU occupancy rate of the service process 9 is 15%. The historical operating time of the service process 5 is 6 hours, the historical operating time of the service process 6 is 2 hours, the historical operating time of the service process 7 is 3 hours, the historical operating time of the service process 8 is 5 hours, and the historical operating time of the service process 9 is 12 hours.

The service processes 5, 6, 7 are ended, enabling the overload value of the node control devices to be less than or equal to the load threshold; ending the service processes 5 and 8 also enables the overload value of the node control devices to be less than or equal to the load threshold. The end of the service process 9 can also cause the overload value of the node control device to be less than or equal to the load threshold.

If the preset number is 2, the 2 first optional process groups with the minimum total running time can be obtained as the first optional process group formed by the service processes 5, 6 and 7 and the first optional process group formed by the service processes 5 and 8.

And then, selecting a first optional process group formed by the service processes 5 and 8 from the two first optional process groups as a target optional process group, wherein the service processes 5 and 8 are service processes to be ended.

905. The node control equipment sends a process ending instruction to the overload node, wherein the process ending instruction comprises process identifications of one or more service processes to be ended, and the process ending instruction is used for indicating the overload node to end the one or more service processes to be ended.

After receiving the instruction of ending the process, the overload node ends one or more service processes to be ended according to the process identifiers of the one or more service processes to be ended, so that the load of the node is in a normal state.

Before sending a process ending instruction to an overload node, the node control device may send a process ending prompt, where the process ending prompt is used to prompt a user to end one or more service processes to be ended;

and after receiving a confirmation ending instruction triggered by a user, the node control equipment sends an ending process instruction to the overload node. Therefore, after the user confirms, the process to be ended is ended, the service which the user needs to use or is using can be avoided being ended, and the user experience is better.

Therefore, when the node control equipment detects the overload node, the node control equipment can control the overload node to finish one or more service processes, so that the load of each node in the block chain network can be adjusted, and abnormal operation caused by overhigh load of the node production time is avoided.

The third target node is any one node in the block chain network, and the third target node may be the same as or different from the first target node or the second target node. In this way, the node control device can restart the abnormal service process when discovering the abnormal service process, and ensure the normal operation of each service in the block chain network.

Further, when the node control device detects that a second service in the one or more services of the blockchain network exists in the updated service installation file, the node control device sends a service update instruction to a third target node deployed with the second service, where the service update instruction includes the service installation file, and the service update instruction is used to instruct the third target node to start a second service, and start a second service process corresponding to the second service according to the service installation file. The second service is a service corresponding to the service installation file which is updated in the block chain network. Therefore, when the node control equipment finds that the service installation file of a certain service is updated, the node control equipment sends the updated service installation file to the node corresponding to the service, and controls the node to start the corresponding service process according to the updated service installation file when the service is started, so that the node control equipment can update each service process in the block chain network in time, a user can conveniently realize various functions by using each service in the block chain network, more functions can be realized by using the block chain, and the block chain technology is more fully utilized.
