[0048] refer to Figure 1 The following is a flowchart illustrating an application configuration distribution method provided by an embodiment of the present invention. Figure 1 The illustrated method execution process is a feasible implementation scheme of the application configuration distribution method provided in the embodiments of the present invention. This application configuration distribution method can be applied to the processor of the control system in an SDN system. Specifically, the method may include:

[0049] S101: Receive the target application configuration input by the current user;

[0050] In the method provided by this embodiment of the invention, the processor of the control system receives the target application configuration input by the current user. The target application configuration may be the relevant configuration generated during the user's current configuration of the system.

[0051] S102: Determine the application ID corresponding to the target application configuration;

[0052] In the method provided by this embodiment of the invention, each application configuration corresponds to a corresponding application ID, and the relevant application configurations are distinguished by the application ID.

[0053] S103: Lock the application ID so that only the current user is allowed to operate on the configuration of each application under the application ID within a set time period;

[0054] In the method provided by this embodiment of the invention, during the current user's system configuration process, the application IDs of each application configuration operated by the current user are locked, so that only the current user is allowed to operate on the application configurations under that application ID within a set time period. The set time period is the time interval between the current user's operations on the application configurations, or it can be a specific operation moment.

[0055] In the method provided by this embodiment of the invention, locking the application ID can specifically involve, during the current user's configuration operation, assigning the current user's user identifier to each application currently operated by the current user, and setting the application configuration with the user identifier to only allow the current user to perform the operation.

[0056] S104: Insert a task record corresponding to the target application configuration into the established task list;

[0057] In the method provided by this embodiment of the invention, a task list is established. Each time the current user operates on an application configuration, a corresponding task record for that application configuration is inserted into the task list.

[0058] S105: Save the target application configuration to a pre-set database;

[0059] In the method provided by this invention, each application configuration issued by the current user operation needs to be saved to a pre-set database.

[0060] S106: When the task record is executed, the target application configuration and each pre-application configuration are obtained from the database. The pre-application configuration belongs to the application ID and its issuance time is earlier than that of the target application configuration.

[0061] In the method provided by this embodiment of the invention, each task record in the task list needs to be executed in its corresponding time order. When the task record corresponding to the target application configuration is executed, the target application configuration and each preceding application configuration are obtained from the database. The preceding application configuration is the application configuration belonging to the application ID, and the issuance time of the preceding application configuration is earlier than that of the target application configuration.

[0062] S107: The target application configuration and each of the preceding application configurations are combined into a configuration package, and the configuration package is sent to the configured proxy system to trigger the proxy system to configure the device to be configured according to each application configuration in the configuration package.

[0063] In the method provided by this embodiment of the invention, the acquired target application configuration and the configuration of each front-end application are combined into a configuration package, and the configuration package is sent to a pre-set proxy system, triggering the proxy system to configure the device to be configured according to the configuration of each application in the configuration package.

[0064] In the method provided by this embodiment of the invention, during the process of the current user updating the system configuration, when the application configuration is distributed, the application ID of the application configuration currently operated by the user is locked, so that only the current user is allowed to operate on the various application configurations under the application ID within a predetermined time period. This ensures that different users will not configure at the same time during the application configuration distribution process, thus preventing configuration disorder and guaranteeing the success of system configuration.

[0065] The method provided in this embodiment of the invention further includes:

[0066] After the configuration package is sent to the configured agent system, the application ID is unlocked.

[0067] In this invention, after the configuration package is successfully sent to the agent system, the application ID is unlocked.

[0068] In the method provided by this embodiment of the invention, triggering the agent system to configure the device to be configured according to the application configurations in the configuration package includes:

[0069] The agent system is triggered to match each application configuration in the configuration package with each application configuration already set in memory to determine multiple configurations to be updated; the configurations to be updated are application configurations that exist in the configuration package but do not exist in the memory.

[0070] Configure the device to be configured according to each of the configurations to be updated.

[0071] In this invention, the agent system matches each application configuration in the configuration package with each application configuration that already exists in the memory, determines each configuration to be updated for the update operation, and configures the device to be configured according to each configuration to be updated to ensure that the device to be configured is in the latest configuration state.

[0072] The method provided in this embodiment of the invention further includes:

[0073] The system receives acquisition requests sent by the agent system at predetermined intervals, acquires the latest application configuration from the database based on the acquisition requests, and sends the latest application configuration to the agent system.

[0074] The method provided in this embodiment of the invention further includes:

[0075] When a network failure occurs between the agent system and the agent system, after the network failure is restored, the agent system receives a channel establishment request and establishes an application configuration distribution channel with the agent system based on the channel establishment request; and distributes the latest application configuration from the database to the agent system.

[0076] In this invention, when a network failure occurs between the agent system and the control system, after the network failure is restored, the agent system sends a channel establishment request to the control system to establish a configuration distribution channel, and matches it with the various application configurations in the database to determine the latest application configuration. The control system then distributes the latest application configurations to the agent system.

[0077] The method provided in this embodiment of the invention further includes:

[0078] When the agent system fails and restarts, the system receives a registration request from the agent system, registers the agent system according to the registration request, establishes an application configuration distribution channel with the agent system, and distributes the latest application configuration from the database to the agent system.

[0079] In this invention, after the agent system fails and restarts, the agent system sends a registration request to the control system, registers in the control system, further establishes an application configuration distribution channel, matches it with the various application configurations in the database, determines the latest application configuration, and the control system distributes the latest application configurations to the agent system.

[0080] refer to Figure 2 The diagram illustrates an architecture of an SDN system provided by an embodiment of the present invention. The SDN system includes: an application system, a control system, a database, a proxy system, and a switch.

[0081] in:

[0082] The application system is used to receive the application configuration distribution request input by the current user and generate the target application configuration corresponding to the application configuration distribution request;

[0083] The control system is configured to: receive the target application configuration sent by the application system; determine the application ID corresponding to the target application configuration; lock the application ID to allow only the current user to operate on each application configuration under the application ID within a set time period; insert a task record corresponding to the target application configuration into the established task list; save the target application configuration to the database; when the task record is executed, retrieve the target application configuration and each preceding application configuration from the database, wherein the preceding application configuration belongs to the application ID and its issuance time is earlier than the target application configuration; assemble the target application configuration and each preceding application configuration into a configuration package, and send the configuration package to the agent system to trigger the agent system to configure the switch according to each application configuration in the configuration package.

[0084] exist Figure 2 Based on the SDN system architecture shown, combined with Figure 1 The application configuration distribution method shown below provides a further explanation of the specific process of application configuration distribution:

[0085] Software-defined networking (SDN) is a network management approach that supports dynamically programmable network configuration, improving network performance and management efficiency, and enabling network services to offer flexible customization capabilities similar to cloud computing. SDN decouples the forwarding plane from the control plane of network devices, with the controller responsible for managing network devices, orchestrating network services, and scheduling traffic. It offers advantages such as low cost, centralized management, and flexible scheduling. SDN systems typically consist of an application layer, a control layer, and an infrastructure layer.

[0086] Application layer: Common examples include cloud platforms based on the OpenStack architecture. Alternatively, users can build their own cloud management platforms based on OpenStack.

[0087] Control layer: Composed of SDN control software, it can communicate with forwarding devices through standardized or proprietary protocols to control the infrastructure layer.

[0088] Infrastructure layer: mainly consists of forwarding devices that implement forwarding functions, such as data center switches.

[0089] The purpose of this invention is to provide a reliable method for distributing SDN network application configurations, ensuring configuration consistency between the control layer and the infrastructure layer in an SDN system.

[0090] The SDN system provided in this embodiment of the invention includes an application system, a control system, a database, an agent system, and switches. The application system corresponds to the application layer, the control system and database correspond to the control layer, and the agent and switches correspond to the infrastructure layer.

[0091] Specifically, each switch deploys a corresponding agent. After the agent starts, it actively registers with the control system and establishes a gRPC channel with the control system for the distribution of application configurations.

[0092] The application system generates application configurations for users based on their configuration requirements. Application configurations are isolated from each other at the application ID level. Each application ID may contain multiple configurations of different types, such as configuration A, configuration B, configuration C, etc. (See also...) Figure 3 .

[0093] The application system sends its application configuration to the control system via an HTTP delivery channel. Upon receiving the application configuration, the control system saves it to the database and inserts a task record into the configured TASK table, marking the task status as "pending." See the TASK table structure for details. Figure 4 In this invention, the task status of the task record can include four states: "pending", "processing", "success", and "failure".

[0094] After receiving the application configuration, the control system first locks the configuration based on the application ID to prevent conflicts caused by concurrent processing of multiple application configurations with the same application ID. After successfully acquiring the lock, business processing is performed, and the application configuration is stored in the database. Then, based on the application ID, all configurations under the current application ID are retrieved. For example, if the current configuration is configuration C, but configurations A and B already exist under the same application ID, then configurations A, B, and C are packaged into a single gRPC package and pushed to the agent. In other words, all configurations A, B, C, etc. under the current application ID are retrieved and pushed to the agent together. Finally, the lock is unlocked and the TASK status is updated to "success". If the processing fails, it is updated to "failure".

[0095] After receiving the complete configuration for the application ID, the agent compares it with the existing configuration in memory and performs corresponding add, delete, or modify operations on the switch.

[0096] The agent has reconciliation capabilities and can periodically retrieve the latest configuration from the control system at the application ID level and update the latest configuration to the switch.

[0097] When the control system restarts due to a failure, the agent will proactively initiate a request to re-establish the gRPC channel and trigger a full configuration reconciliation to ensure that the latest configuration can be distributed to the switch.

[0098] When a network failure occurs between the agent and the control system, causing the gRPC channel to be disconnected, the agent will immediately initiate a request to re-establish the gRPC channel and initiate a full configuration reconciliation once the network is restored, ensuring that the latest configuration can be distributed to the switch.

[0099] When the agent restarts after a failure, it immediately initiates a re-registration with the control system and triggers a full configuration reconciliation to ensure that the latest configuration can be distributed to the switch.

[0100] The application configuration distribution method provided in this embodiment of the invention controls the system to lock at the application ID granularity, which not only ensures the concurrency of configuration between different application IDs, but also ensures the reliability of configuration under the same application ID, and prevents the occurrence of configuration out-of-order situations.

[0101] With the agent acting as the client and the control system as the server, if any failure occurs in any link of the agent, control system, or intermediate network, the agent will re-initiate the establishment of the gRPC channel and immediately perform a full configuration reconciliation after the channel is established to ensure that the configuration between the control system and the switch is completely consistent, which greatly increases the system's fault recovery capability.

[0102] When the control system distributes configurations, it does not distinguish between operation types, such as Add, Delete, Update, etc. Regardless of the operation, the control system will obtain all configurations under the application ID and re-push them to the agent, which will then push them to the switch. The advantage of this approach is that if configuration A fails to be distributed, subsequent configurations B and C will not be able to be distributed. This eliminates the possibility of configuration loss due to interdependence between configurations, greatly improving the reliability of the system.

[0103] Specific practical applications can be as follows:

[0104] Application system generates configuration: Application ID=1 contains 3 different types of configurations: Configuration A, Configuration B, Configuration C;

[0105] The application system sends "Application ID=1 Configuration A" to the control system;

[0106] After receiving "Application ID=1 Configuration A", the control system generates a TASK record, locks the application based on the configured application ID, stores the configuration "Application ID=1 Configuration A" in the database, pushes configuration A to the agent, unlocks the application, and updates the TASK status.

[0107] The application system sends "Application ID=1 Configuration B" to the control system;

[0108] After receiving "Application ID=1 Configuration B", the control system generates a TASK record, locks the application based on the configured application ID, stores the configuration "Application ID=1 Configuration B" in the database, pushes configuration A and configuration B to the agent, unlocks the application, and updates the TASK status.

[0109] The application system sends "Application ID=1 Configuration C" to the control system;

[0110] After receiving "Application ID=1 Configuration C", the control system generates a TASK record, locks the application based on the configured application ID, stores the configuration "Application ID=1 Configuration C" in the database, pushes configuration A, configuration B and configuration C to the agent, unlocks the application, and updates the TASK status.

[0111] The agent has reconciliation capabilities and periodically retrieves the latest configuration from the control system at the application ID level, and updates the latest configuration to the switch.

[0112] When the control system restarts after a failure, the agent will proactively initiate a gRPC channel re-establishment request and trigger a full configuration reconciliation to ensure that the latest configuration can be distributed to the switch.

[0113] When a network failure occurs between the agent and the control system, causing the gRPC channel to be disconnected, the agent will immediately initiate a request to re-establish the gRPC channel after the network is restored, and initiate a full configuration reconciliation to ensure that the latest configuration can be distributed to the switch.

[0114] When the agent restarts after a failure, it immediately initiates a re-registration with the control system and triggers a full configuration reconciliation to ensure that the latest configuration can be distributed to the switch.

[0115] The configuration distribution method provided in the embodiments of the invention can be used to implement a highly reliable network configuration distribution system, avoiding system unreliability caused by a series of problems such as system failure, network failure, concurrency, and interdependence between configurations.

[0116] This invention also provides an application configuration distribution device corresponding to an application configuration distribution method. This device is used to implement the application configuration distribution method in practice. A structural diagram of the application configuration distribution device can be found here. Figure 5 The application configuration distribution device includes:

[0117] The receiving unit 201 is used to receive the target application configuration input by the current user;

[0118] Determining unit 202 is used to determine the application ID corresponding to the target application configuration;

[0119] The locking unit 203 is used to lock the application ID so that only the current user is allowed to operate on the configuration of each application under the application ID within a set time period.

[0120] The insertion unit 204 is used to insert a task record corresponding to the target application configuration into the established task list;

[0121] The storage unit 205 is used to save the target application configuration to a pre-set database.

[0122] The acquisition unit 206 is used to acquire the target application configuration and each pre-application configuration from the database when the task record is executed. The pre-application configuration belongs to the application ID and its issuance time is earlier than that of the target application configuration.

[0123] The distribution unit 207 is used to combine the target application configuration and each of the preceding application configurations into a configuration package, and distribute the configuration package to the configured proxy system to trigger the proxy system to configure the device to be configured according to each application configuration in the configuration package.

[0124] In the device provided in this embodiment of the invention, during the process of the current user updating the system configuration, when the application configuration is distributed, the application ID of the application configuration currently operated by the user is locked, so that only the current user is allowed to operate on the various application configurations under the application ID within a predetermined time period. This ensures that different users will not configure at the same time during the application configuration distribution process, resulting in configuration disorder, and guarantees the success of system configuration.

[0125] The application configuration distribution device provided in this embodiment of the invention includes a processor and a memory. Each of the above units can be stored in the memory as a program unit, and the processor executes the above program units stored in the memory to realize the corresponding functions.

The processor 301 and memory 302 communicate with each other via the bus 303. The processor 301 is used to call program instructions in the memory 302 to execute the aforementioned application configuration distribution method.

[0136] When the task record is executed, the target application configuration and each of the preceding application configurations are retrieved from the database. The preceding application configurations belong to the application ID and are issued earlier than the target application configuration.

[0137] The target application configuration and each of the preceding application configurations are combined into a configuration package, and the configuration package is sent to the configured proxy system to trigger the proxy system to configure the device to be configured according to each application configuration in the configuration package.
