Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a configuration method, which can be applied to a network configuration system, such as a session manager object established in the network configuration system. Taking a network configuration system including an established session manager object and a configuration module as an example, as shown in fig. 1, the configuration method of the present embodiment includes the following steps:
step 101: it is determined that configuration data is transmitted to at least one network device to be configured.
Specifically, the configuration data corresponds to a single change transaction, and the single change transaction occurs in a thread corresponding to the session manager. When single service change occurs and the external device sends a configuration instruction to the network configuration system, the network configuration system sends data contained in the configuration instruction to the corresponding configuration module, the configuration module generates related configuration data, and the generated configuration data is sent to the related network device.
In one embodiment, the network configuration system and the network devices communicate based on the NETCONF protocol. The network device is a server in NETCONF, the network configuration system is a client of NETCONF, and the established session manager object comprises a NETCONF session manager object, which can be realized by Thread local object.
In one embodiment, to avoid different configuration change services from interacting, the session manager object in the network configuration system may be set to respond to only one configuration change service at a time.
In the network configuration system, each configuration change service uses a respective thread, a session manager object exists in each thread, and the session manager object executes the configuration method, so that concurrent services are not influenced by each other.
It should be noted that the same thread uses one session manager object, and it is ensured that in one service change, the configuration module in the network configuration system and the same network device only establish one network configuration session through the session manager object, all configuration changes caused by the service change are transmitted through the session, and the configuration changes are either all effective or not all effective, so that atomicity of the network configuration service level is realized. Different session manager objects are used by different configuration change services, thereby ensuring that the services use independent sessions and the concurrent services are mutually influenced.
In one embodiment, a network configuration system includes a configuration module and a session manager object. The configuration module is used for generating configuration data and sending the data to at least one network device, and the session manager object manages a session between the configuration module and the at least one network device. Specifically, a configuration module related to the current configuration change service requests a session with the network device from a session manager object, and the session manager object receives a session request of the configuration module; judging whether to establish a session for communicating with at least one network device to be configured; if the session communicated with at least one network device to be configured is determined to be established, returning the information of the established session to the configuration module; otherwise, creating a session communicated with at least one network device to be configured, and returning the created session information to the configuration module; the configuration module transmits configuration data to at least one network device to be configured through a session. After each related configuration module completes the respective configuration data transmission task, a transmission completion instruction is sent to the session manager object, so that the session manager object executes the subsequent related steps after determining that the configuration data of each configuration module are completely transmitted.
Step 102: and sending a validation operation instruction to at least one network device to be configured.
Specifically, the validation operation instruction instructs the at least one network device to validate the configuration data. In this embodiment, the network configuration system manages the configuration validation process of the network device in a unified manner. And after receiving the effective operation instruction, the network equipment takes the configuration data into effect.
In one embodiment, an initial database (start Configuration database), a Candidate database (Candidate Configuration database), and a running database (RunningConfiguration database) are provided in the network device. The initial database stores the original configuration data of the network device, and is a configuration library loaded when the network device is started. The candidate database is a backup configuration in that modifying the configuration does not affect the operational state of the network device. The operation database stores the configuration data activated by the current network equipment. The validation operation is to activate the configuration in the candidate database to make the network device run according to the configuration data in the candidate database.
Step 103: and judging whether the configuration data of the at least one network device is effective successfully.
Specifically, if the configuration data of all the network devices are successful in validation, the configuration is successful, and the process is ended, and if the configuration data of any one of the network devices fails in validation, step 104 is executed.
In one embodiment, after the configuration data is successfully or unsuccessfully validated, the network device sends a prompt message to a session manager object in the network configuration system, where the prompt message indicates that the configuration data is successfully or unsuccessfully validated, so that the network configuration system determines whether the configuration data is successfully validated.
In one embodiment, each network device sends a prompt to the network configuration system after the configuration data is successfully validated, the prompt indicating that the configuration data is successfully validated. If the network configuration system receives the prompt message within the preset time, it is determined that the configuration data of the network equipment is successful in effect, and if the network configuration system does not receive the prompt message within the preset time, it is determined that the configuration data of the network equipment is failed in effect. Wherein, the length of the preset time can be set according to the requirement.
It should be noted that, as can be understood by those skilled in the art, in practical applications, whether the configuration is valid may be detected in other ways, and this embodiment is merely an example, and does not limit the method for determining whether the configuration data is valid by the network configuration system in practical applications.
Step 104: and sending a rollback operation instruction to the network equipment with failure in effectiveness.
Specifically, the rollback operation instruction instructs the at least one network device to perform a rollback operation. And after receiving the rollback operation instruction, the network equipment performs rollback operation.
In one embodiment, an initial database, a candidate database and an operation database are arranged in the network device (the configuration data is transmitted to the network device and then stored in the candidate database of the network device; the configuration data is stored in the operation database of the network device after the configuration data is validated).
In one embodiment, after the configuration data of any one network device fails to take effect, the rollback operation is sent to not only the network device which fails to take effect, but also a rollback operation instruction is sent to other network devices except for the network device which fails to take effect. And meanwhile, the configuration information is sent to all the network equipment to be configured, so that the configuration synchronization of the network equipment corresponding to the current change service can be ensured, and a plurality of network equipment are configured under different conditions.
It should be noted that, in practical applications, after the rollback operation instruction is sent to the network device that fails to take effect, the configuration data and the validation operation instruction may also be sent to the network device that fails to take effect again.
In one embodiment, when there are multiple concurrent change services, the number of session managers is greater than 1, and each session manager corresponds to a change service.
The above description is only for illustrative purposes and does not limit the technical aspects of the present invention.
Compared with the prior art, by adopting the configuration method provided by the embodiment, the network configuration system can control the network equipment which fails to take effect to carry out the rollback operation by sending the rollback operation instruction to the network which fails to take effect, and the initial configuration of the network equipment is recovered, so that the operation of recovering the original configuration of the network equipment is simpler when the configuration fails. In addition, the same NETCONF session manager object is used by the single configuration change service, and the session manager object executes the validation, error detection and rollback of the NETCONF configuration, so that the atomicity of the single service change of the cross-equipment is realized.
A second embodiment of the invention relates to a configuration method. The second embodiment is substantially the same as the first embodiment, and mainly differs therefrom in that: in this embodiment, a step of sending an update operation instruction is added.
Specifically, as shown in fig. 2, the present embodiment includes steps 201 to 205, where steps 201 and 202 are substantially the same as steps 101 and 102 in the first embodiment, and are not repeated here. The following mainly introduces the differences:
step 201: it is determined that configuration data is transmitted to at least one network device to be configured.
Step 202: and sending a validation operation instruction to at least one network device to be configured.
Step 203: and judging whether the configuration data of all the network equipment to be configured take effect successfully or not.
Specifically, if it is determined that all the configuration data of the network devices to be configured are successful in validation, step 204 is executed, and after it is determined that there is a network device for which the configuration data fails to be validated, step 205 is executed.
In one embodiment, each network device sends a prompt message to the network configuration system after the configuration data of the network device becomes effective, and the network configuration system considers that the configuration data of all the network devices become effective successfully if receiving the prompt messages sent by all the network devices, otherwise, considers that the network device with the failure in effectiveness of the configuration data exists.
Step 204: and sending an updating operation instruction to all the network equipment to be configured.
Specifically, the update operation instruction instructs the network device to copy the data in the operational database to the initial database. I.e. reloading the configuration data in the original database.
Step 205: and sending a rollback operation instruction to all the network equipment to be configured.
Specifically, after determining that there is a network device for which the configuration data fails to take effect, the network configuration system sends a rollback operation instruction to all network devices to be configured.
In one embodiment, the session manager object comprises a Thread local object.
It should be noted that, through the Thread local mode, it can be ensured that the same session manager is used for a single configuration change service, thereby ensuring the atomicity of the transaction of the configuration change service.
It should be noted that, as can be understood by those skilled in the art, in practical applications, a single-instance mode of the session manager object may also be implemented by other modes, and this embodiment does not limit the setting manner of the session manager object.
In one embodiment, after determining that an error occurs in a configuration flow of the configuration change service, the network configuration system ends a session between a configuration module in a thread corresponding to the configuration change service and the network device. Specifically, if a step is executed incorrectly in the process of executing the relevant program corresponding to the configuration method by the session manager object, a filter (JavaServlet filter) or a Spring MVC interceptor callback function may be called to automatically clean up the session in the thread corresponding to the configuration change service, so as to ensure that the same NETCONF session is not used for the two previous and subsequent configuration change services.
The following description will exemplify a configuration method by taking a network configuration system based on Thread local and NETCONF protocols as an example.
Supposing that a network configuration system is developed by using Java Web technology, a plurality of configuration modules and session manager objects corresponding to each thread are arranged, the session manager objects are communicated with network equipment based on a NETCONF protocol (namely, the NETCONF session manager objects), and a Map data structure can be used in the session manager objects to manage the NETCONF session, so that only one NETCONF session is established for the same network equipment. A schematic diagram of the interaction of the network configuration system and the network devices is shown in fig. 3. Wherein, the same configuration change service can be executed in the same Java thread. The session manager object for each Thread is a Thread Local object. The reference of the session manager object is dispersed in each configuration module, and as long as each configuration module runs in the same Java thread, the same session manager object is referred to, so that a thread-level singleton object is realized. Communication between the network configuration system and the network devices (e.g., gateway a and/or gateway B) is uniformly managed by the session manager object. When a configuration module needs to send configuration data to a network device, it first requests a NETCONF session with the corresponding network device from the session manager object. If the NETCONF session with the corresponding network device is not established, the session manager object establishes the NETCONF session with the corresponding network device, stores the NETCONF session in the session manager object and returns the NETCONF session to the configuration module. If a NETCONF session with the network device has been established, the NETCONF session is returned directly. Therefore, although configuration data included in the configuration change service may be generated by a plurality of configuration modules, the configuration data may be transmitted to a candidate database (NETCONF database) of a corresponding network device through the same NETCONF session, and the session manager object may also initiate a rollback operation instruction through the NETCONF session, so that the network device connected to the NETCONF session performs a rollback operation. And after the configuration data of each configuration module is completely sent, the session manager object sends a validation (COMMIT) operation instruction to each network device. And if the COMMIT operation of a certain network device fails in the execution process of the method, performing rollback operation on the network device which successfully executes the COMMIT operation. The rollback operation is to copy the configuration in the initial database to the running database. And if the effective COMMIT operations of the network devices are successful, controlling the network devices to copy the running database into the initial database so as to ensure that the restart configuration of the devices is not lost. If the network configuration system processes a plurality of configuration change services simultaneously, the concurrent configuration change services occur in respective Java threads, each Java thread has an independent session manager object, and each session manager object manages its own NETCONF session, so that the concurrent configuration change services do not affect each other. By decoupling the NETCONF session management of the session manager object from the session usage, a singleton mode is used to ensure that configuration changes of each configuration module in the same configuration change service are transmitted to the network device through the same NETCONF session. This enables the configuration in the same NETCONF session to be either all in effect (COMMIT) or not in effect (COMMIT), thereby achieving atomicity of configuration changes for a single network device. And the session manager object manages NETCONF sessions to a plurality of network devices at the same time, and if the NETCONF sessions fail, the session manager object can roll back the configuration which is already in effect to realize the atomicity of configuration change of the cross-device. The singleton mode of the session manager object can be realized through Thread Local, so that concurrent services can be realized without mutual influence. The session manager object is used for managing the NETCONF session in a unified mode, and random use of the NETCONF session by each configuration module can be achieved without considering whether the NETCONF session is established repeatedly or not, and programming of the configuration modules is simplified. In addition, because the JAVA Web program thread is multiplexed, in order to ensure that even if a service change has an error, the NETCONF session can still be closed, and configuration data confusion caused by subsequent service change multiplexing is avoided, the session manager object ends the session in the thread corresponding to the configuration change service after determining that the configuration flow of the configuration change service has an error. For example, cleaning up a possible NETCONF session may be achieved by adding a callback function in the Java Servletfilter or Spring MVC interceptor.
The above description is only for illustrative purposes and does not limit the technical aspects of the present invention.
Compared with the prior art, by adopting the configuration method provided by the embodiment, the network configuration system can control the network equipment to perform rollback operation by sending the rollback operation instruction, and recover the initial configuration of the network equipment, so that the operation of recovering the original configuration of the network equipment is simpler when the configuration fails. In addition, the same NETCONF session manager object is used by the single configuration change service, and the session manager object executes the validation, error detection and rollback of the NETCONF configuration, so that the atomicity of the single service change of the cross-equipment is realized.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
