Description

Technical Field

[0001] This invention relates to the field of computer technology, and in particular to a distributed loosely coupled information distribution method, apparatus, electronic device, and storage medium. Background Technology

[0002] In distributed multi-node simulation systems, the complex network topology between information nodes makes the information communication connection of the simulation system very complicated. Especially with the dynamic evolution of the simulation system, when it is necessary to dynamically update the connection relationship between nodes, how to perform dynamic connection in real time and efficiently to ensure the normal evolution of the simulation system is one of the urgent problems to be solved in the simulation system.

[0003] To address this issue and improve data exchange efficiency, the main approach is to decouple the connections between nodes, making each node relatively independent. By decoupling the sending and receiving logic between nodes, the complexity of system data transmission is reduced. Currently, the primary solution for distributed data distribution is the Data Distribution Service (DDS), described as follows: DDS, published by the Object Management Group (OMG), is a data distribution / subscription standard specifically designed for real-time systems. It employs a decentralized approach, establishing connections through a node "discovery" mechanism, thereby decoupling the connections between nodes. When sending data, the sending node publishes a topic through a publisher. The sending node does not care which nodes receive the data; the receiving node only needs to subscribe to the topic published by the sending node to receive the data. In this way, decoupling between sending and receiving is achieved.

[0004] However, the applicability of DDS data distribution service in simulation systems is limited by the number of nodes. As the number of nodes increases, when the system's node transmission and reception are mainly based on mesh nodes, each node needs to subscribe to multiple topics, and each topic requires a separate thread to listen for reception. When changes occur in the system simulation, such as new nodes joining or existing nodes leaving, each node needs to reconstruct its reception rules, increasing the overall complexity of the system.

[0018] If there is a mapping relationship between the sending information node and the receiving information node corresponding to the sending information node, then the legality verification is passed;

[0019] If there is no mapping relationship between the sending information node and the receiving information node corresponding to the sending information node, the validity verification will fail.

[0020] Furthermore, the sending information node and the receiving information node have a one-to-one relationship, and / or the sending information node and the receiving information node have a one-to-many relationship.

[0021] Secondly, embodiments of the present invention provide a distributed loosely coupled information distribution device, comprising:

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The distributed loosely coupled information distribution method provided by the present invention will be explained and described in detail below through specific embodiments.

[0043] Figure 1 This is a flowchart illustrating a distributed information loosely coupled distribution method according to an embodiment of the present invention; as shown below. Figure 1 As shown, the method includes:

[0044] Step 101: Receive a request generated by the terminal based on node data exchange configuration information; wherein, the node data exchange configuration information includes a sending information node and a receiving information node corresponding to the sending information node.

[0045] In this step, it should be noted that a data simulation distribution center or server is deployed in the system to receive requests generated by the terminal based on the node data exchange configuration information.

[0046] In this step, it should be noted that several information nodes are deployed on the terminal. These information nodes can be either sending or receiving information nodes.

[0047] In this step, it should be noted that the node data exchange configuration information includes sending information nodes and receiving information nodes corresponding to the sending information nodes. For example, sending information node 1 sends data to receiving information nodes 2, 3, and 4; or sending information node 1 sends data to receiving information nodes 2, 3, 5, and 6; or sending information node 2 sends data to receiving information nodes 3 and 4; or sending information node 4 sends data to receiving information node 3.

[0048] Step 102: Perform a validity verification based on the node data exchange configuration information in the request.

[0049] In this step, it is understood that a storage mapping table or a validity verification module is set up in the data simulation distribution center or server to verify the validity of the node data exchange configuration information in the request. For example, if the pre-stored information is for information node 1, and information nodes 2, 3, 4, 7, and 8 are valid receiving information nodes, then when sending information node 1 sends data to receiving information nodes 2, 3, and 4, the validity verification passes; when sending information node 1 sends data to receiving information nodes 2, 3, 5, and 6, the validity verification fails. If the pre-stored information is for receiving information node 3, and sending nodes 1 and 4 are valid sending information nodes, then when sending information node 2 distributes data to receiving information nodes 3 and 4, the validity verification fails.

[0050] Step 103: If the legitimacy verification is passed, the sending node is determined to be a legitimate sending node, and a data distribution channel is established for the legitimate sending node based on the node data exchange configuration information; wherein, the data distribution channel is used to distribute legitimate data packets; the legitimate data packets are data packets sent by the legitimate sending node.

[0051] In this step, it can be understood that after a legitimate sending node is identified, if the node data exchange configuration information indicates that sending node 1 sends data to receiving nodes 2, 3, and 4, then a data distribution channel is established for nodes 1-2, nodes 1-3, and nodes 1-4. This process continues, establishing channels for all legitimate sending nodes, such as establishing a data distribution channel for nodes 4-3, etc.

[0052] Step 104: Receive the data packet sent by the sending node and determine whether the node data exchange configuration information has been updated.

[0053] In this step, based on the previous steps, when a data packet is received, check whether the node's data exchange configuration information has been updated.

[0054] Step 105: If the node data exchange configuration information is updated, a data distribution channel is established for the legitimate information sending node based on the updated node data exchange configuration information.

[0055] In this step, it is understood that if an update is found after comparing the latest node data exchange configuration information, a data distribution channel needs to be established for the legitimate information sending node so that the data packets can be correctly distributed.

[0056] In this embodiment, it should be noted that the purpose of this invention is to solve the problem of dynamic connection of information nodes as the simulation evolves in a distributed multi-node simulation system. When there is a need for dynamic connection and the interface connection between multiple nodes changes dynamically, it is only necessary to adjust the connection mapping of the data simulation distribution center, without having to reconstruct the receiving rules of each node. This invention is particularly suitable for distributed multi-node simulation networks with high real-time requirements and complex and rapidly changing node connection relationships.

[0057] The node connection model of the simulation system targeted in this embodiment of the invention is as follows: Figure 2 As shown. To simplify the problem, this example illustrates that the connection model only considers the link situation of simulated nodes within a local area network. The simulation system network has M information nodes. Information processing nodes can be deployed in one or more computers depending on the hardware's computing power. The computers are connected via a network interface, ensuring that each node can communicate with the others through the network. Simultaneously, a data simulation exchange and distribution center is deployed in the network. Data from the information nodes first enters the data simulation exchange and distribution center. The data simulation exchange and distribution center distributes the data to each node according to the node data exchange configuration information, achieving data sharing within the system, such as... Figure 3 As shown, M information nodes are deployed in 2 computers. All node data is connected to the data simulation exchange and distribution center via a switch. The data simulation exchange and distribution center distributes data according to the configuration information. When there are many information nodes, the number of data simulation exchange and distribution centers can be increased to achieve load balancing and also serve as redundancy backup. Figure 4 As shown.

[0058] To better understand the present invention, the following embodiments further illustrate the content of the present invention, but the present invention is not limited to the following embodiments.

[0059] For example:

[0060] All computers and data simulation switching and distribution centers are on the same IP segment and interconnected via network switches. The node switching configuration is as follows: Node 1 sends data and distributes it to Node 2 and Node M; Node 2 sends data and distributes it to Node 1 and Node M; Node M sends data and distributes it to Node 1 and Node 2. (See [link to configuration]). Figure 5 .

[0061] Step 1: M node programs start and actively send RTS packets to the data simulation exchange and distribution center.

[0062] Step 2: At this point, there are two different situations.

[0063] 1) Case 1: The data simulation exchange and distribution center receives an RTS packet sent by a node, verifies that it is a legitimate node, sends a CTS packet to the corresponding node, which contains access permission information, and establishes a data distribution channel for this node according to the node's data exchange configuration.

[0064] 2) Scenario 2: The data simulation exchange and distribution center receives an RTS packet sent by a node, verifies that it is an illegitimate node, and sends a CTS packet containing access prohibition information to the corresponding node.

[0065] Step 3: After the system displays that all legitimate nodes have connected to the data simulation exchange and distribution center, the user starts the system simulation, and all nodes begin sending data packets.

[0066] Step 4: The node sends a data packet. After the data simulation exchange and distribution center receives the data packet from the legitimate node, it distributes the data according to the established node data distribution channel.

[0067] Step 5: The data simulation exchange and distribution center determines whether the exchange configuration information has been updated.

[0068] 1) If the configuration information is not updated, return to step 4;

[0069] 2) If the exchange configuration information is updated, the data simulation exchange and distribution center reconstructs the node data distribution channel according to the latest exchange configuration information. After completion, it returns to step 4.

[0070] Based on the distributed loosely coupled information distribution method provided in this invention, a distributed network information on-demand distribution model based on a simulation system is defined, including the distributed access of multiple information nodes, channel logical mapping, and on-demand distribution processes. The distributed loosely coupled information distribution method provided in this invention can guarantee efficient data transmission between information nodes. Even with dynamic changes in nodes, this method can quickly respond to simulation system deductions by dynamically reconstructing the node data channels of the data simulation exchange and distribution center.

[0071] Compared to the DDS data distribution service, the distributed loosely coupled information distribution method provided in this embodiment of the invention can achieve an on-demand distribution mode through the settings of steps 101 to 105. The advantage is that each information node only needs to interface with the data simulation exchange and distribution center, and does not need to reconstruct the receiving channel of each node due to the addition or reduction of nodes. This can significantly reduce the complexity of the entire system implementation when there are many nodes. In contrast, the DDS data distribution service is limited by the scale of information nodes. In the case of many-to-many connections, it needs to instantiate multiple receiving channels, and dynamically reconstruct the receiving channel of each node when the system nodes change, which increases resources and overhead and increases the complexity of the system, especially on nodes with limited resources.

[0072] As can be seen from the above technical solution, the distributed loosely coupled information distribution method provided by this invention receives a request generated by a terminal based on node data exchange configuration information. The node data exchange configuration information includes a sending node and a receiving node corresponding to the sending node. The method performs a validity verification based on the node data exchange configuration information in the request. If the validity verification passes, the sending node is determined as a valid sending node, and a data distribution channel is established for the valid sending node based on the node data exchange configuration information. The data distribution channel is used to distribute valid data packets. The valid data packets are data packets sent by the valid sending node. The method receives the data packets sent by the sending node and determines whether the node data exchange configuration information has been updated. If the node data exchange configuration information has been updated, a data distribution channel is established for the valid sending node based on the updated node data exchange configuration information. This invention can achieve rapid response by dynamically reconstructing the data distribution channel when nodes change dynamically, which helps reduce costs.

[0073] Based on the above embodiments, this embodiment further includes:

[0074] After receiving the data packet sent by the sending node, the legitimacy of the sending node is determined to ascertain whether the sending node is a legitimate sending node.

[0075] In this implementation, it is understood that when there is a dynamic connection requirement, and the interface connection between multiple information nodes changes dynamically, the preset connection mapping needs to be adjusted. Therefore, for a certain receiving information node, the sending information node that has a mapping relationship with the receiving information node may change. In this case, it is necessary to further determine the legitimacy of the sending information node to determine whether the sending information node is still a legitimate sending information node.

[0076] As can be seen from the above technical solution, the distributed loosely coupled information distribution method provided by the embodiments of the present invention, by performing a legality judgment on the sending information node after receiving the data packet sent by the sending information node, determines whether the sending information node is a legitimate sending information node, which is beneficial to the accuracy of data distribution and avoids losses caused by untimely system response.

[0077] Based on the above embodiments, this embodiment further includes:

[0078] If the node data exchange configuration information has not been updated, data distribution is performed based on the data distribution channel.

[0079] In this implementation, it is understood that if the judgment result is that the node data exchange configuration information has not been updated, then the data distribution can be completed based on the data distribution channel established initially or in the previous opinion.

[0080] Based on the above embodiments, in this embodiment, the legitimacy verification based on the node data exchange configuration information in the request specifically includes:

[0081] The validity of the node data exchange configuration information in the request is verified based on a preset mapping table; the preset mapping table is used to determine whether there is a mapping relationship between the sending information node and the receiving information node corresponding to the sending information node when performing the validity verification.

[0082] If there is a mapping relationship between the sending information node and the receiving information node corresponding to the sending information node, then the legality verification is passed;

[0083] If there is no mapping relationship between the sending information node and the receiving information node corresponding to the sending information node, the validity verification will fail.

[0084] Based on the above embodiments, in this embodiment, the sending information node and the receiving information node have a one-to-one relationship, and / or the sending information node and the receiving information node have a one-to-many relationship.

[0085] In this embodiment, it can be understood that the sending information node and the receiving information node have a one-to-one relationship, such as sending information node 1 sending data to information node 2; the sending information node and the receiving information node have a one-to-many relationship, such as sending information node 1 sending data to information nodes 2 and M; the sending information node and the receiving information node have a one-to-one relationship, and the sending information node and the receiving information node have a one-to-many relationship, such as sending information node 1 sending data to information nodes 2 and M, and sending information node 2 sending data to information node 5.

[0086] As can be seen from the above technical solutions, the distributed loosely coupled information distribution method provided by the embodiments of the present invention, through the one-to-one relationship between the sending information node and the receiving information node, and / or the one-to-many relationship between the sending information node and the receiving information node, is conducive to achieving flexible configuration.

[0088] The first receiving module 201 is used to receive a request generated by the terminal based on node data exchange configuration information; wherein the node data exchange configuration information includes a sending information node and a receiving information node corresponding to the sending information node.

[0089] The first judgment module 202 is used to perform legality verification based on the node data exchange configuration information in the request;

[0090] The first establishment module 203 is used to determine the sending node as a legitimate sending node if the legitimacy verification is passed, and to establish a data distribution channel for the legitimate sending node based on the node data exchange configuration information; wherein, the data distribution channel is used to distribute legitimate data packets; the legitimate data packets are data packets sent by the legitimate sending node;

[0091] The second receiving module 204 is used to receive data packets sent by the sending information node and determine whether the node data exchange configuration information has been updated.

[0092] The second establishment module 205 is used to establish a data distribution channel for legitimate information sending nodes based on the updated node data exchange configuration information if the node data exchange configuration information is updated.
