Therefore, disaster recovery and hot standby scenes meeting high reliability requirements are met.
For example, the technical solution of the present disclosure may be implemented by the following embodiments.
FIG. 1 illustrates a flow chart of some embodiments of the backup and restore method of the present disclosure.
As shown in fig. 1, in step 110, in case a backup enable command of a user is received, configuration information is generated.
In some embodiments, configuration information is issued to the interface module by the configuration module in accordance with a backup enable command entered by a user.
For example, after the user inputs the NSR enable command in the command line interface, the NSR-cli module (configuration module) parses and verifies the command and then issues configuration information to the NSR-api module (interface module).
In step 120, in response to the configuration information, protocol process information that needs to be backed up is determined.
In some embodiments, the process features that need to be backed up are obtained using an interface module; and determining corresponding protocol process information according to the process characteristics by utilizing an interface module. For example, the interface module establishes a connection with the standby main control board in response to the configuration information, and issues a warning message if the connection fails.
For example, after receiving the NSR enable configuration information, the NSR-api module establishes a connection with the standby main control board through HTTP (HyperText Transfer Protocol ) service; and then confirming the process of the needed backup according to the process characteristics, and sending the protocol process information to the nsr-sync module (synchronization module).
For example, after receiving NSR enabling configuration information, the NSR-api module obtains a pre-stored configuration file, where the configuration file includes synchronization requirement information of a user; and determining the process needing backup according to the synchronous demand information.
In step 130, the backup file is determined based on the protocol process information.
In some embodiments, a synchronization module is utilized to generate a backup file according to protocol process information, and the backup file is stored in a data module; transmitting the backup file to other nodes includes: and establishing connection with the standby main control board by using the data module, and transmitting the standby file to the standby main control board.
For example, the nsr-sync module, upon receiving the backup program information (protocol process information), starts backup and stores the backup file in the nsr-data module. And the nsr-data module establishes connection with the standby main control board after receiving the backup data, and starts file transmission.
In step 140, the backup file is transmitted to other nodes.
In some embodiments, the synchronization module is utilized to perform real-time incremental backups of the backup program after the first round of backups is completed. For example, after the first round of batch backup is completed, the nsr-sync module begins to perform real-time incremental backup of the backup program.
In some embodiments, in the case of receiving the system switching information, notifying the synchronization module to perform system recovery; and the backup file is read from the data module by utilizing the synchronous module so as to realize the hot migration of the protocol process corresponding to the backup file. For example, the system switch information is used to trigger the backup node to upgrade to the primary node.
For example, the system may be an NSR system. And carrying out hot migration of the protocol process according to the backup file transmitted above, thereby realizing uninterrupted routing.
In some embodiments, the system switch information entered by a user is received using an interface module. For example, the user inputs an NSR system switch command on the command line interface, informing NSR-api module to perform NSR system switch.
In some embodiments, system switch information is triggered in the event that the interface module detects a system failure. For example, the NSR-api module monitors the system in real time and triggers an NSR system switch after a fault is found.
In some embodiments, the system switch information is triggered in case the LPU senses a failure of the active main control board. For example, the LPU senses a failure of the primary master control board and notifies the SMB to perform a primary up operation.
In some embodiments, after the nsr-api module of the SMB receives the system switch information, the nsr-sync module is notified to perform system recovery; nsr-sync module reads the backup file from nsr-data module and restores the program through the criu-restore (user space checkpoint-restore).
In step 150, the backup file is used for system recovery according to the system requirements.
FIG. 2 illustrates a schematic diagram of some embodiments of the backup and restore method of the present disclosure.
As shown in FIG. 2, the full protocol stack uninterrupted routing system based on the thermal migration comprises a nsr-cli module, a nsr-api module, a nsr-sync module and a nsr-data module. The main node, namely the source node of the backup, is AMB (Active Main Board, main control board); the backup node is SMB (Slave Main Board), and the backup node is a standby Main control Board.
In some embodiments, the NSR-cli module is responsible for defining and loading NSR related commands, decomposing and processing information entered by the user, and issuing command configurations. For example, the nsr-cli module provides nsr relevant command support and issues command configuration.
In some embodiments, the nsr-api module is responsible for monitoring the system in real time, defining the restful (Representational State Transfer, representing state transition) interfaces of nodes, mirrors, restores, migration, etc.; http service is provided, and support is provided for inter-node connections.
For example, the nsr-api module monitors the system, provides http services for the source node and the backup node, provides a master-slave node management function, provides a master-slave node control information synchronization function, and supports management of the backup node through commands.
In some embodiments, the nsr-sync module is responsible for incremental memory mirroring/restoration of business processes based on optimizing CRIU checkpoints/Restore In Userspace, user space checkpoints/restoration). The nsr-sync module can perform real-time backup and thermal migration of processes of the whole protocol stack, and also support batch backup and thermal migration of process trees at a container level.
For example, the nsr-sync module performs live backup and live migration of protocol processes/process trees; and restoring the process or the process tree according to the backup file.
In some embodiments, the nsr-data module is responsible for storing backup files and providing file transfer services. For example, NSR backup files are stored, file transfer services are provided, and the system is monitored in real time.
In the above embodiment, protocol processes such as BGP and ISIS are abstracted to be network APP with common attributes, and a general system component module is used to implement different types of protocol process hot migration. Therefore, NSR function development is not required to be carried out aiming at an independent protocol, the development period of the NSR function is greatly shortened, dependence on external programs during thermomigration is reduced, and the process thermomigration efficiency is improved.
Fig. 2 illustrates some embodiments of a system backup phase, including the following steps.
In the step of using NSR by the user, after the user inputs an NSR enabling command on the command line interface, the NSR-cli module analyzes and verifies the command and then issues configuration information to the NSR-api module.
In the step of establishing connection of the NSR-api module, after receiving NSR enabling configuration information, the NSR-api module establishes connection with a standby main control board through HTTP service; and then confirming the process of the needed backup according to the process characteristics, and sending the protocol process information to the nsr-sync module.
In the step of program backup, the nsr-sync module starts backup after receiving the backup program information and stores the backup file in the nsr-data module. And the nsr-data module establishes connection with the standby main control board after receiving the backup data, and starts file transmission.
In the step of real-time backup, after the first round of batch backup is completed, the nsr-sync module starts to perform real-time incremental backup on the backup program.
FIG. 3 illustrates a schematic diagram of further embodiments of the backup and restore method of the present disclosure.
As shown in fig. 3, the system switching phase includes the following steps.
In the step of triggering system switching, system switching may be triggered by one of the following means: a user inputs an NSR system switching command on a command line interface, and notifies a NSR-api module to perform NSR system switching; the NSR-api module monitors the system in real time and triggers NSR system switching after finding out a fault; the LPU senses the failure of the main control board and notifies the SMB to perform main lifting operation.
In the step of upgrading the backup node to the main node, after the nsr-api module of the SMB receives the system switching information, informing the nsr-sync module to recover the system; the nsr-sync module reads the backup file from the nsr-data module and restores the program through the criu-restore.
In the embodiment, through the modules, the whole protocol stack uninterrupted routing system based on the thermal migration can be formed. Uninterrupted route function development aiming at a protocol is not needed, the development period of NSR functions is shortened, dependence on external programs during thermomigration is reduced, and the process thermomigration efficiency is improved.
