[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0024] With the development of new-generation information network technology and the massive data integration generated by the Internet of Everything, data management planning is becoming more and more reasonable, which can meet the data transmission needs of different application scenarios. Distributed parallel computing is a key means to realize AI large model training, which usually includes multiple parallel computing modes such as data parallelism, pipeline parallelism and tensor parallelism. All parallel modes require multiple collective communication operations between multiple computing devices. Facing the future scale construction of intelligent computing centers and the development and deployment needs of AI large models, creating a new intelligent computing center network with non-blocking, high bandwidth and ultra-low latency can effectively help AIGC (AI Generated Content) and other high-performance businesses to develop rapidly.

[0025] However, data centers in related technologies mostly use a solidified network architecture, which has drawbacks in terms of data transmission reliability, real-time and stability. The CLI (Command-Line Interface) configuration method used by the switching and routing equipment in the data center has the problem of incompatible configuration commands, and requires high professional knowledge of engineers, high manual maintenance costs, and is prone to high error rates during the configuration process, which cannot effectively adapt to the development trend of contemporary network technology.

[0026] Specifically, the session protocol used in the related art specifies the structure of the message in the protocol and the architecture of reading and parsing according to the byte stream. In order to better express a richer message structure in the byte stream, TLV (Type-Length-Value) and other methods are used to define objects. However, the scalability of this method is limited. For example, if the object is expanded or modified, the code needs to be changed. Moreover, the byte stream-based session protocol used in the related art can be regarded as a program with a clear execution process, so the data model can be compared to a programming language for writing programs. If a large amount of private data is extended to a protocol, then first of all, there will be major problems with the compatibility of the protocol. Secondly, the code of its protocol stack is almost completely rewritten, which is time-consuming and labor-intensive.

[0027] Based on this, according to an embodiment of the present application, a parameter configuration method embodiment is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0028] In this embodiment, a parameter configuration method is provided, which is applied to a configuration server, where the configuration server is communicatively connected to a target network device. Figure 1a According to the flow chart of the parameter configuration method of the embodiment of the present application, Figure 1a As shown, the process includes the following steps:

[0029] S110: Display the constraint file model content corresponding to the target network device.

[0030] In some cases, in view of the limitations of parameter configuration methods in related technologies, if you want to improve the flexibility, intelligence and efficiency of the network, you can use a custom parameter configuration method that separates the data management plane and the data service plane in the cluster network.

[0031] Specifically, the cluster network may include a configuration server and a target network device (client). The configuration server may be a physical device of the management plane, which may be connected to a target network device with the network management protocol enabled through a CLI interface to obtain and operate the configuration data of the device. The target network device may refer to any client device such as a switch, router, and storage device in the cluster network. For example, Figure 1b This is a schematic diagram of cluster network equipment networking, please refer to Figure 1b The target network device (client) can be any of the Spine devices, Leaf devices, and GPU (Graphics Processing Unit) server devices that support network management protocols such as Openflow, Netconf (Network Configuration Protocol), SNMP (Simple Network Management Protocol), RESTCONF, gNMI, BGP-LS, and XMPP, and can support mandatory SSH and TLS as the transmission protocol.

[0032] Further, Figure 1b The application APPs shown in the figure can be network control and management applications (Apps) developed for business needs. The northbound interface can refer to the interface connected to the core devices in the cluster network. Specifically, through the northbound abstraction, the application APPs can obtain the global network view to simplify the development of management, control and configuration services. Among them, the global network view can provide the application with relevant network topology information, including hosts, switching and forwarding devices, and network-related status indicators. The application is an intelligent management tool that can be programmed based on the global network view through the API interface (Application Programming Interface). The southbound interface can refer to the interface connected to the client devices (such as personal computers, servers, etc.) in the cluster network. Through the southbound interface, the core of the configuration server can be isolated from the details of different devices (clients) and protocols.

[0033] For example, Figure 1bAs shown in , the southbound interface allows the system to create a unified network management view using various network components, such as Spine devices, Leaf devices, and GPU servers. The configuration server, through southbound abstraction, can uniformly convert the various network elements in the cluster network into standardized objects. It can be understood that through this method, the distributed core system of the configuration server can maintain the state of the network elements, and can achieve communication connection and configuration without knowing the details of each network element represented by the underlying driver. Furthermore, the configuration server and its southbound abstraction can also allow various southbound protocols and client devices to use plug-ins. Among them, the plug-in can map and convert the general network element description and operation on the client device into a language that the client device can understand, so that when the client device uses different protocols (such as OpenFlow protocol, etc.), the configuration server can also control or manage various different client devices.

[0034] It is understandable that the northbound interface and southbound interface of the configuration server provide the initial basis for isolating the application, core layer and adapter from each other, that is, separating the management plane of data from the business plane of data. Through this separated modular design, the configuration server can be used as a software system, so that developers and service providers can more conveniently carry out post-development according to their needs. And the stability of the system can be maintained and upgraded through continuous parameter debugging. At the same time, since the configuration server is built as a system composed of multiple independent components, and the direct dependency between modules is realized through the north-south interface module, the modules also maintain relatively small dependencies. The dependency between them can form an acyclic graph, thus avoiding complex dependency chains, making the system structure clearer and facilitating future expansion and upgrades.

[0035] Based on this, a parameter configuration method applied to a configuration server, and the configuration server is communicatively connected to a target network device, can first display the constraint file model content corresponding to the target network device. Among them, the constraint file can refer to a standardized document that defines the structure, syntax and semantics of the data model, as well as the hierarchical organization and constraints of the data. It can be understood as a standard-based, extensible hierarchical data modeling language used to model the configuration and status data used for network management protocol operations, remote procedure calls (RPCs) and server event notifications. Exemplarily, the constraint file can be regarded as a template for parameter configuration, which not only clarifies the grammatical structure of the data, but also describes the semantic meaning of the data in detail. Through the constraint file model content, the association between data and constraints can be explicitly defined, so that users can quickly and directly create configuration data that meets the constraint requirements and is grammatically correct in a customized manner.

[0036] Furthermore, the constraint file can not only exist as a complete independent unit, but also introduce the definition of other modules and sub-modules, and allow the existing data model to be extended by adding additional nodes. Specifically, although the device configuration data is stored in the form of an XML (eXtensible Markup Language) document, the specific nodes and allowed values ​​in the document can be flexibly defined, and support conversion to YIN format using XML-based syntax. Exemplarily, IETF (Internet Engineering Task Force) can be used, in which many models that allow flexible definition of nodes are directly created to further support the standardization and unification of network management protocol interfaces of common network devices. That is, the system of a standard computer can be described in the network interface configuration defined in the IETF-system model (RFC7317) or the IETF-interfaces model (RFC7223). For each system, some specific parameters are required in the network to ensure that the network protocol can work properly. These parameters need to be configured according to the specific network protocol requirements to ensure that the network can operate efficiently and stably to meet the data transmission requirements under large-scale networking.

[0037] It is important to understand that since the cluster network architecture uses northbound and southbound interfaces, in conjunction with constraint files, the interaction between the client and the configuration server becomes more standardized through standardized interfaces (northbound and southbound interfaces) and data models (constraint files), so that the management plane of data and the business plane of data can be separated. Therefore, the configuration data in the constraint file no longer needs to strictly focus on the parameters of the network itself, that is, in addition to the RPC defined by the network management protocol, it can also describe its characteristics, such as the version information of the protocol session, the identifier information of the device, the timestamp, the transmission protocol or security configuration, whether SSH or TLS security encryption is supported, etc.

[0038] Specifically, the constraint file model content includes a first configuration parameter corresponding to the current operating state of the target network device.

[0039] The first configuration parameter may refer to a configuration parameter of the target network device in the current operating state. Specifically, the first configuration parameter may define the operating behavior of the device, such as QoS settings, port configuration, traffic management, etc., and may also reflect the configuration settings currently being used by the device.

[0040] It should be understood that the model data of the cluster network can include both state data and configuration data. Among them, state data refers to the inherent attribute data of the client and the dynamic information data of the current operation, etc. This type of data is only for call query. Configuration data refers to static information data that defines the behavior and operation mode of network devices. Since configuration data allows users to customize configurations according to needs, it itself has different representations. Exemplarily, the configuration data may include effective configuration data corresponding to the current state data after the client applies it; it may also include pre-effective configuration data that has been modified by the network administrator or user but has not yet been applied to the client and is only waiting to be submitted for effectiveness; it may also include the startup configuration data of the client's own application when the initial configuration state is started.

[0041] Therefore, based on this, after the network control management application on the configuration server responds to the request of the network administrator or user, it will display the constraint file model content corresponding to the target network device. Among them, the constraint file model content includes the first configuration parameter of the target network device, and the first configuration parameter can be the configuration parameter of the target network device in the current operating state, that is, the effective configuration data currently being used by the device.

[0042] S120. In response to the configuration parameter modification operation, modify the first configuration parameter to a second configuration parameter suitable for the target network device.

[0043] Among them, the second configuration parameter may refer to a new configuration parameter obtained by a network administrator or user after modifying the first configuration parameter according to new business requirements or network changes, that is, obtaining the second configuration parameter. Exemplarily, the second configuration parameter may also include a backup QoS configuration, a port list configuration, and a traffic management configuration (traffic speed limit, bandwidth allocation, and bandwidth priority strategy) to optimize device performance, adjust new security policies, and traffic management rules. Specifically, the network administrator or user may modify and adjust the configuration parameters of the target network device on the network control management application on the configuration server side according to the network performance monitoring results or business demand changes, and modify the first configuration parameter to a second configuration parameter suitable for the target network device.

[0044] It should be understood that in the process of modifying the first configuration parameter to the second configuration parameter, since the management plane of data and the business plane of data are separated by adopting northbound and southbound interfaces, while the network administrator or user customizes the first configuration parameter according to new business requirements or network changes, the target network device continues to operate normally in the current operating state with the first configuration parameter.

[0045] S130. Send a second configuration parameter in a constraint file model format to the target network device, so that after receiving the second configuration parameter, the target network device still maintains the current operating state with the first configuration parameter, and when the target network device is started next time, it starts according to the second configuration parameter to enter the operating state corresponding to the second configuration parameter.

[0046] It is understandable that, since the second configuration parameter is generated by customizing and modifying the first configuration parameter, the configuration server also uses the constraint file model format when sending the modified second configuration parameter to the corresponding target network device. That is, the second configuration parameter is also encapsulated in the constraint file model and stored in the form of an XML document.

[0047] Furthermore, since the management plane of data and the business plane of data are separated in operation, the target network device still maintains the current operation state with the first configuration parameter after receiving the second configuration parameter. Until the next startup, the second configuration parameter is used to overwrite the first configuration parameter, and the device is started according to the second configuration parameter to enter the operation state corresponding to the second configuration parameter, that is, the network device is allowed to smoothly transition to the new configuration state without interrupting the service.

[0048] In the above implementation, by displaying the constraint file model content corresponding to the target network device, the user can be allowed to dynamically adjust the configuration parameters according to the actual operating status and needs of the network device, thereby providing users with a high degree of flexibility to adapt to different network environments and business needs. At the same time, in the process of modifying the first configuration parameter to the second configuration parameter, it is ensured that the target network device can continue to maintain the current operating state with the first configuration parameter, so that the network device does not need to interrupt service during the configuration update process, thereby ensuring the continuity and real-time performance of the network. Thus, a real-time configuration method that can flexibly and dynamically adjust network device parameters according to needs without interrupting service is realized.

[0049] In some implementations, the configuration server is communicatively connected to multiple network devices; before displaying the constraint file model content corresponding to the target network device, please refer to the attached Figure 2 , the method further comprises:

[0050] S210 . In response to a network device selection operation, determine a target network device whose configuration parameters need to be modified among multiple network devices.

[0051] The network device selection operation may refer to a process in which a network administrator or user independently selects one or more specific devices for configuration management among multiple network devices. The target network device may refer to a network device that is selected after the network device selection operation and that can accept new configuration parameters. Specifically, the network administrator or user may input the IP address of the target network device on the network control management application at the configuration server end to determine the target network device for which the configuration parameters need to be modified.

[0052] S220: Establish a network management protocol session between the configuration server and the target network device.

[0053] It can be understood that the network management protocol session may refer to a communication connection established between the configuration server and the target network device for transmitting configuration data and management commands.

[0054] Exemplarily, such a session follows a specific network management protocol, such as SNMP (Simple Network Management Protocol), NETCONF or RESTCONF, to ensure accurate data transmission and correct management of the device. Specifically, a suitable network management protocol can be selected according to the network environment and device support, and necessary communication parameters can be set. Exemplarily, the IP address, port number, community string (for SNMP) or user name and password (for NETCONF or RESTCONF) of the target device can be included.

[0055] Further, the configuration server will send an initialization request to the target network device to establish a session, thereby verifying the identities and communication parameters of both parties. Once the identity verification is successful, the target network device will confirm the establishment of the session and can prepare to receive management commands.

[0056] When a link is established between the configuration server and the target network device through a network management protocol session, the target network device can reply to the configuration server with a message that contains the features and capabilities supported by the network device itself, mainly including version information of the protocol session, device identifier information, timestamp, transmission protocol or security configuration, whether SSH or TLS security encryption is supported, and other information.

[0057] It can be understood that since the target network device (client) can be a network device that supports mandatory SSH and TLS as transmission protocols, that is, the network management protocol session can include protocols using SSH (Secure Shell) and TLS (Transport Layer Security) as secure transport layers, the client can use any of these two transmission protocols to establish a network management protocol session link when the connection is successful, and send a network management protocol RPC (remote procedure call) command to the configuration server so that the configuration server provides an accurate response based on this command.

[0058] Optionally, the client can also implement most of the key functions in the RFC 6241 standard, including verifying the new configuration before applying it to ensure the security and compatibility of the new configuration. Or being able to return to the previous configuration when the application of the new configuration fails to ensure the stability of the network. At the same time, access control is also supported, that is, each user has a designated available part of the configuration for reading and writing, and cannot access any other configuration, ensuring that each user can only access and modify the configuration part they are authorized to, thereby enhancing the security and controllability of network management.

[0059] In the above implementation, the network administrator or user can accurately select a specific network device for configuration management, and conveniently call and display the constraint file model content corresponding to the target network device by configuring the network control management application on the server side. This process not only simplifies configuration management, but also ensures the accuracy and real-time nature of the configuration.

[0060] In some implementations, the first configuration parameter is stored in a configuration information repository of the target network device in a constraint file model format. The method further includes: sending a parameter locking instruction to the target network device.

[0061] The parameter locking instruction is used to instruct the target network device to lock the configuration information base and continue to maintain the current operating state with the first configuration parameter.

[0062] It can be understood that the Configuration Information Base (CIB) is a key component in the network management system, which is used to store various configuration data and status information of network devices.

[0063] Specifically, after a target network device whose configuration parameters need to be modified is selected and a network management protocol session link is established between the configuration server and the target network device, in order to ensure that during the configuration modification process, the first configuration parameter currently running by the target network device will not be affected by the operations of other users or administrators, the configuration server can send a parameter lock instruction to the target network device to instruct the target network device to lock its configuration information base to prevent other operations from changing the configuration.

[0064] In the above implementation, after the network management protocol session is established between the configuration server and the target network device, the parameter locking instruction is implemented to ensure that during the configuration modification period, the device will continue to operate with the first configuration parameters, while preventing intervention by other users or administrators, avoiding potential configuration conflicts and errors, thereby ensuring the accuracy and reliability of the configuration process.

[0065] In some implementations, the configuration information repository includes a primary configuration database, a backup configuration database, and a startup configuration database.

[0066] The parameter locking instruction is used to instruct the target network device to lock the main configuration database or to lock the main configuration database, the backup configuration database and the startup configuration database at the same time.

[0067] Specifically, during the network management process, the configuration server communicates with the target network device through a network management protocol session and sends a parameter locking instruction to lock the main configuration database, or simultaneously locks the main configuration database, the backup configuration database, and the startup configuration database to prevent other operations from changing the configuration when making configuration changes, thereby ensuring the accuracy of the configuration process.

[0068] Among them, the main configuration database can be used to save the configuration parameters corresponding to the current operating state of the target network device, that is, to save the effective configuration data corresponding to the current state data after the client applies it. The backup configuration database can be used to save the backup data of the configuration parameters, that is, to save the pre-effective configuration data that has been modified by the network administrator or user but has not yet been applied to the client and is only waiting to be submitted for effectiveness. It should be understood that the configuration parameters stored in the backup configuration database are consistent with those in the main configuration database, that is, the main configuration database and the backup configuration database can be redundantly configured to each other. The startup configuration database can be used to save the recovery configuration parameters used after the target network device is restarted. Among them, the recovery configuration parameters refer to the data that can ensure the normal operation of the client device when the device is initialized and started.

[0069] Specifically, when the user wants to modify the configuration parameters of the target network device, the user can call the first configuration parameters of the target network device currently running stored in the main configuration database of the client on the network control management application of the configuration server, and modify them. In this process, the first configuration parameters will also be backed up in real time in the backup configuration database. If the main configuration database fails and cannot be used at this time, the data stored in real time in the backup configuration database can be used to continue to run. Furthermore, if the backup configuration database also fails and cannot be used at this time, the recovery configuration parameters of the initial state can be called from the startup configuration database to ensure that the target network device will not be unable to run due to damage to the main configuration database and the backup configuration database.

[0070] Exemplarily, taking the port configuration parameters as an example, when a certain network device is initialized and started, port 1 is used, so the port configuration parameters stored in the main configuration database, backup configuration database and startup configuration database of the network device are all port 1. Further, the user changes port 1 to port 2, then the port configuration parameters stored in the main configuration database and the backup configuration database are all port 2, and the port configuration parameters stored in the startup configuration database are still port 1. If the main configuration database of the network device suddenly cannot be opened at this time, the port configuration parameters of port 2 can be obtained from the backup configuration database to continue running. If the main configuration database and the backup configuration database of the network device are damaged and cannot be opened at the next moment, the port configuration parameters can only be obtained from the startup configuration database for port 1. Configuration parameters are run, and the configuration parameters are modified again, and port 1 is changed to port 2 again to meet new needs.

[0071] In the above implementation, the locking mechanism is used to prevent other operations or users from changing the configuration when the configuration is changed, thereby maintaining the stable operation of the network device when the configuration parameters are modified. At the same time, by designing three databases, both the old configuration parameters before the modification and the new configuration parameters after the modification are backed up. Furthermore, if there is a problem with the new configuration parameters, it can be quickly rolled back to the old configuration parameters, thereby ensuring the stability and reliability of the network.

[0072] In some implementations, after the target network device modifies the first configuration parameter into the second configuration parameter, the method further includes: sending a parameter unlocking instruction to the target network device.

[0073] The parameter unlocking instruction is used to release the lock state of the configuration information base.

[0074] Specifically, after the target network device successfully modifies the first configuration parameter to the second configuration parameter, the configuration server sends a parameter unlocking instruction to the target device. The parameter unlocking instruction is used to inform the target network device that the configuration modification process has been completed and the lock status of the main configuration database, the backup configuration database, and the startup configuration database can be released.

[0075] Furthermore, after receiving the parameter unlocking instruction, the target network device will correspondingly release the locked state of the configuration information base, restore it to a normal state, and allow other users or administrators to operate data services or make possible configuration changes later.

[0076] In the above implementation, the sending of the unlock instruction indicates the successful completion of the configuration modification process, thereby allowing the network device to release the lock state of the configuration information base, restore normal operation, and provide the possibility for subsequent configuration changes. By sending the parameter unlock instruction after the target network device successfully modifies the first configuration parameter to the second configuration parameter, not only the integrity of the configuration change and the stability of the network are ensured, but also the flexibility and security of network configuration management are improved.

[0077] In some implementations, the method further includes: if the second configuration parameter in the constraint file model format passes the compliance check of the target network device, receiving a confirmation response sent by the target network device.

[0078] It is understandable that after the configuration parameters are modified, the modified configuration parameters may not be correctly applied to the target network device. For example, taking the port configuration parameters as an example, when a certain network device is initialized and started, port 1 is used. When modifying, port 1 is changed to port 10, but the network device may not have port 10, so the modification at this time is illegal and cannot be correctly applied to the target network device.

[0079] Therefore, after the first configuration parameter is modified to the second configuration parameter, the configuration server will send a compliance check command to the target network device so that the target network device can perform compliance check on the modified second configuration parameter.

[0080] Compliance checking refers to a series of legality checks on new configuration parameters before they are applied to verify whether they comply with the hardware and software requirements of network devices, network policies, security standards, and any related service level agreements (SLAs). Specifically, compliance checking can include basic syntax verification, structure and rule checking, entity and character reference verification, element data type and range constraint checking, etc.

[0081] Specifically, when making modifications, the configuration server will send the second configuration parameters in the constraint file model format to the target network device. After receiving the second configuration parameters, the target network device can parse these parameters through its verification module and perform compliance verification on the new configuration parameters according to predefined rules and standards to ensure the legality, compatibility and reliability of the configuration parameter settings. If the second configuration parameters pass all compliance checks, the target network device will send a confirmation response to the configuration server, indicating that the new configuration parameters have been accepted and are ready to be applied. However, if the second configuration parameters cannot pass the compliance check of the target network device, the target network device will not send a confirmation ACK response frame, indicating that the modification of the second configuration parameters is illegal and the modification is invalid.

[0082] In the above implementation, by implementing compliance verification, the legality, compatibility and reliability of network device configuration parameters are also ensured. At the same time, it is ensured that only configuration parameters that meet the network device hardware and software requirements, network policies, security standards and service level agreements can be applied, thereby significantly improving the security and effectiveness of network management.

[0083] In some implementations, the first configuration parameter is stored in a master configuration database of the target network device in a constraint file model format. After receiving the confirmation response, the method further includes: sending a parameter modification instruction to the target network device so that the target network device modifies the first configuration parameter in the master configuration database into a second configuration parameter, and during the process of the target network device modifying the first configuration parameter, the target network device still maintains the current operating state with the first configuration parameter.

[0084] Specifically, after receiving a confirmation response based on compliance verification from the target network device, the configuration server will send a parameter modification instruction to the target network device to instruct the device to start modifying the current configuration parameter (first configuration parameter) in the main configuration database to a new configuration parameter (second configuration parameter). After receiving the parameter modification instruction, the target network device will start the update process in its main configuration database, thereby replacing the first configuration parameter with the second configuration parameter. Exemplarily, the second configuration parameter can be directly overwritten with the second configuration parameter, which is also stored in the main configuration database in the constraint file model format and synchronized to the backup configuration database.

[0085] Optionally, since the main configuration database and the backup configuration database are mutually redundant, the backup configuration database can also allow repeated operations of custom parameter configuration. After confirming that the modified second configuration parameters pass the compliance test, the main configuration database can also be overwritten with the parameter configuration of the backup database to achieve data backup.

[0086] It should be noted that in this process, since the management plane of the data and the business plane of the data are separated in operation, the operating state of the target network device will not be disturbed during the process of the target network device modifying the first configuration parameter in the main configuration database to the second configuration parameter, and it can still maintain the current operating state according to the first configuration parameter. Exemplarily, after the target network device modifies the first configuration parameter in the main configuration database to the second configuration parameter, a data update request can be displayed in a pop-up window on its front end. If the user agrees to update, the target network device is restarted in response to the consent request, and runs with the modified second configuration parameter as the configuration parameter. If the user does not agree to update, the second configuration parameter can be temporarily stored in the configuration database, and the current running process will not be forcibly interrupted to update the configuration parameter. Instead, the next time the target network device is started, it will be directly started and run according to the modified second configuration parameter as the configuration parameter.

[0087] In the above implementation, after confirming that the second configuration parameter has passed the compliance check and receiving the confirmation response, the configuration server will instruct the target network device to update the parameters in the main configuration database to the new configuration, while ensuring that the device continues to run with the first configuration parameter to ensure that the service is not interrupted. The device will not be restarted and the new configuration parameters will not be applied until the user confirms the update, thereby ensuring the stability of the network device and the flexibility of parameter updates.

[0088] In some implementations, the first configuration parameter is at least one of a QoS configuration parameter, a port list configuration parameter, and a traffic management configuration parameter.

[0089] Among them, QoS configuration parameters (Quality of Service Configuration Parameters) can refer to configuration parameters that define the quality of service of data transmission in the network, which are used to ensure that key applications of the target network device can obtain the necessary bandwidth and low latency to ensure its application performance. Specifically, QoS configuration parameters can include data packet classification, priority allocation, queue management, etc., to achieve differentiated processing of network traffic.

[0090] Port List Configuration Parameters may be configuration parameters related to the configuration of each port on a network device, including enabling, disabling, rate limiting, etc. of the port, which are used to allow network administrators to define which ports can be used for data transmission and the transmission characteristics of how these ports transmit.

[0091] Traffic Management Configuration Parameters may refer to configuration parameters used to control and optimize network traffic, which may include monitoring, analyzing, and adjusting network traffic to prevent network congestion and ensure that service level agreements (SLAs) are met, thereby achieving effective utilization of network resources and maximizing network performance.

[0092] Furthermore, the traffic management configuration parameters include at least one of traffic speed limit, bandwidth allocation and bandwidth priority strategy.

[0093] Traffic Shaping can refer to a traffic management technology used to control the transmission rate of network traffic to prevent certain traffic from occupying too much bandwidth and affecting other traffic. Bandwidth Allocation can refer to a traffic management technology that allocates the total bandwidth of the network to different users, applications or services. Bandwidth Priority Policy can be a traffic management technology that defines the priorities of different types of traffic. It can set the priority of traffic according to its type, source or destination, thereby ensuring that critical business traffic can be given priority in the network.

[0094] In the above implementation, by comprehensively using QoS configuration parameters, port list configuration parameters and traffic management configuration parameters, users can customize configuration parameters according to business needs and transmission needs, realize refined management and optimized allocation of network resources, and ensure the performance of key applications, thereby improving the overall service quality of the network. At the same time, since these parameters can be modified in real time without interrupting the business of the target network device, it not only maximizes the utilization of network resources, but also significantly improves the stability and reliability of the network, providing an efficient, stable and responsive operating environment for the target network device.

[0095] The embodiment of this specification also provides a parameter configuration method, which is applied to a configuration server, and the configuration server is connected to multiple network devices. The first configuration parameter is stored in the configuration information library of the target network device in the format of a constraint file model. The first configuration parameter is at least one of a QoS configuration parameter, a port list configuration parameter, and a traffic management configuration parameter. The traffic management configuration parameter includes at least one of a traffic speed limit, a bandwidth allocation, and a bandwidth priority strategy. The configuration information library includes a main configuration database, a backup configuration database, and a startup configuration database. The method includes the following steps:

[0096] S302: In response to a network device selection operation, determine a target network device whose configuration parameters need to be modified among multiple network devices.

[0097] S304: Establish a network management protocol session between the configuration server and the target network device.

[0098] S306: Send a parameter locking instruction to the target network device.

[0099] The parameter locking instruction is used to instruct the target network device to lock the main configuration database or lock the main configuration database, the backup configuration database and the startup configuration database at the same time, and continue to maintain the current operating state with the first configuration parameter. The main configuration database is used to save the configuration parameters corresponding to the current operating state of the target network device; the backup configuration database is used to save the backup data of the configuration parameters corresponding to the current operating state of the target network device; the startup configuration database is used to save the recovery configuration parameters used by the target network device after restarting.

[0100] S308: Display the constraint file model content corresponding to the target network device.

[0101] The constraint file model content includes a first configuration parameter corresponding to the current operating state of the target network device.

[0102] S310. In response to the configuration parameter modification operation, modify the first configuration parameter to a second configuration parameter suitable for the target network device.

[0103] In the process of modifying the first configuration parameter to the second configuration parameter, the target network device continues to maintain the current operating state with the first configuration parameter.

[0104] S312: Send a second configuration parameter in a constraint file model format to the target network device, so that the target network device performs compliance verification on the second configuration parameter.

[0105] S314: If the second configuration parameter in the constraint file model format passes the compliance check of the target network device, a confirmation response sent by the target network device is received.

[0106] S316. After receiving the confirmation response, send a parameter modification instruction to the target network device so that the target network device modifies the first configuration parameter in the main configuration database to the second configuration parameter. During the process of the target network device modifying the first configuration parameter, the target network device still maintains the current operating state with the first configuration parameter.

[0107] S318: After the target network device modifies the first configuration parameter into the second configuration parameter, send a parameter unlocking instruction to the target network device.

[0108] The parameter unlocking instruction is used to release the lock state of the configuration information base.

[0109] S320: After the target network device changes the first configuration parameter to the second configuration parameter, the target network device still maintains the current operating state with the first configuration parameter, and when it is started next time, the target network device starts according to the second configuration parameter to enter the operating state corresponding to the second configuration parameter.

[0110] It should be understood that, although the various steps in the above flowchart are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear description in this article, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a part of the steps in the above flowchart may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
