Example one
The embodiment of the invention provides a configuration updating method, which is applied to a controller of an SD-WAN (secure digital-to-WAN), and as shown in FIG. 1, the method specifically comprises the following steps:
step S101: when an update instruction for updating the controller-side configuration to a target client terminal of the SD-WAN is detected, a configuration record corresponding to the target client terminal is acquired.
Specifically, before step S101, the method further includes:
when the target client terminal is registered to the controller, generating a unique corresponding configuration record for the target client terminal locally at the controller; wherein the configuration record comprises: the system comprises a controller configuration identifier, a client configuration identifier and a local configuration identifier;
the controller configuration identification is used for representing whether the version of the controller side configuration changes or not; the client configuration identification is used for representing the version of the client side configuration currently on the target client terminal; the local configuration identification is used to characterize a version of the client-side configuration that has been updated locally to the controller. In an initial state, the values of the controller configuration identifier, the client configuration identifier and the local configuration identifier are all 0.
Further, before step S101, the method further includes:
when the controller side configuration is modified, modifying the value of the controller configuration identifier contained in the configuration record, and triggering the update instruction.
In this embodiment, a controller side configuration corresponding to the target client terminal is configured on the controller, and when a user updates the controller side configuration corresponding to the target client terminal on the controller, the controller configuration identifier is modified synchronously, for example, a value of the controller configuration identifier is changed from 0 to 1. In addition, when the controller side configuration is updated, a configuration issuing task is triggered, and an updating instruction is issued to issue the updated controller side configuration to the target client terminal.
Step S102: and judging whether the value of the client configuration identifier contained in the configuration record is consistent with the value of the local configuration identifier.
Further, before step S102, the method further includes:
receiving a keep-alive packet containing a client configuration identifier sent by the target client terminal;
and setting the value of the client configuration identifier in the configuration record as the value of the client configuration identifier in the keep-alive packet.
Wherein the keep-alive packet is periodically sent to the controller by the target client terminal according to a set time interval.
In this embodiment, a client configuration identifier is also set on the target client terminal, where the client configuration identifier is used to characterize a version of a client-side configuration currently on the target client terminal, and in an initial state, the target client terminal sets a value of the client configuration identifier to 0. When the user modifies the client-side configuration on the target client terminal manually, the value of the client configuration identifier is modified from 0 to 1, and a keep-alive packet containing the modified client configuration identifier is sent to the controller, so that the controller can modify the value of the client configuration identifier in the configuration record, and the controller can sense the change of the client-side configuration on the target client terminal through the client configuration identifier.
Step S103: if the configuration is consistent, comparing the client side configuration updated to the local controller with the controller side configuration to determine a difference configuration; or, in the case of inconsistency, acquiring the client-side configuration currently on the target client terminal, and comparing the acquired client-side configuration with the controller-side configuration to determine a difference configuration.
Specifically, before step S103, the method further includes:
and when the target client terminal is registered to the controller, acquiring the client side configuration on the target client terminal, and storing the client side configuration to the local controller.
In this embodiment, if the value of the client configuration identifier in the configuration record is consistent with the value of the local configuration identifier, it indicates that the client-side configuration currently on the target client terminal is consistent with the client-side configuration already existing in the local controller, and the client-side configuration may be directly obtained from the local controller to perform configuration comparison. Furthermore, if the value of the client configuration identifier in the configuration record does not match the value of the local configuration identifier, it indicates that the current client-side configuration on the target client terminal does not match the client-side configuration already existing locally in the controller, and the latest client-side configuration needs to be acquired from the target client terminal to compare the acquired latest client-side configuration with the controller-side configuration.
Therefore, the value of the client configuration identifier in the configuration record is compared with the value of the local configuration identifier to determine whether the client side configuration needs to be acquired from the target client terminal; if the client side configuration is consistent with the client side configuration, the client side configuration does not need to be obtained from the target client terminal, so that the technical problem that more resources are occupied in the configuration comparison process is solved, and the client side configuration needs to be obtained from the target client terminal only under the condition of inconsistency.
Further, after acquiring the client-side configuration currently on the target client terminal in the case of the inconsistency, the method further includes:
updating the acquired client side configuration to the local controller;
and setting the value of the local configuration identifier as the value of the client configuration identifier.
In this embodiment, the controller may sense a change in the client-side configuration on the target client terminal in real time, and when the change in the client-side configuration on the target client terminal is found, modify the client-side configuration identifier from 0 to 1, but not synchronize the client-side configuration on the target client terminal to the local controller; and only when the controller needs to execute the configuration issuing task, the client side configuration on the target client terminal is acquired and stored in the local of the controller, and meanwhile, the local configuration identifier is modified from 0 to 1.
Step S104: and sending the difference configuration to the target client terminal.
In this embodiment, all the control side configurations do not need to be issued to the target client terminal, and only the differential configurations after configuration comparison need to be issued to the target client terminal, so that the resource occupation is reduced, and the configuration issuing efficiency is improved.
Specifically, after step S104, the method further includes:
and when the difference configuration is successfully sent to the target client terminal, setting the value of the controller configuration identifier as the value of the client configuration identifier.
It should be noted that, since the value of the local configuration identifier in the configuration record has been set as the value of the client configuration identifier in step S103, when the differential configuration is successfully sent to the target client terminal, the values of the controller configuration identifier, the client configuration identifier and the local configuration identifier in the configuration record will be consistent.
Example two
The embodiment of the invention provides a configuration updating method, which is applied to a controller of an SD-WAN (secure digital-to-WAN), and as shown in FIG. 2, the method specifically comprises the following steps:
step S201: when an update instruction for updating the controller-side configuration to a target client terminal of the SD-WAN is detected, a configuration record corresponding to the target client terminal is acquired.
Specifically, before step S201, the method further includes:
when the target client terminal is registered to the controller, generating a unique corresponding configuration record for the target client terminal locally at the controller; wherein the configuration record comprises: the system comprises a controller configuration identifier, a client configuration identifier and a local configuration identifier; the controller configuration identification comprises: the template class controller configuration identifier and the policy class controller configuration identifier, wherein the client configuration identifier comprises: template class customer configuration identification and policy class customer configuration identification, the local configuration identification comprising: template class local configuration identification and policy class local configuration identification.
In the present embodiment, the configuration is divided into two main categories: template class configuration and policy class configuration; wherein, the template class configuration comprises: interface, user, IPSEC tunnel, route, strategy route, BGP, DHCP service; the policy class configuration comprises the following steps: security policy, NAT policy, QOS, address object, service object, time object, antivirus policy, vulnerability protection policy. Setting template class configuration identification in the configuration record aiming at template class configuration, and setting strategy class configuration identification in the configuration record aiming at strategy class configuration. In the initial state, the values of the template class controller configuration identifier, the strategy class controller configuration identifier, the template class client configuration identifier, the strategy class client configuration identifier, the template class local configuration identifier and the strategy class local configuration identifier are all 0.
Further, before step S201, the method further includes:
when the controller side configuration is modified, modifying the value of the controller configuration identifier contained in the configuration record, and triggering the update instruction.
In this embodiment, a controller side configuration corresponding to the target client terminal is configured on the controller, and when a user updates the controller side configuration corresponding to the target client terminal on the controller, the controller configuration identifier is modified synchronously, for example, a value of the controller configuration identifier is changed from 0 to 1. In addition, when the controller side configuration is updated, a configuration issuing task is triggered, and an updating instruction is issued to issue the updated controller side configuration to the target client terminal.
Step S202: judging whether the value of the template class client configuration identifier is consistent with the value of the template class local configuration identifier or not and judging whether the value of the strategy class client configuration identifier is consistent with the value of the strategy class local configuration identifier or not; if they are both the same, step S203 is executed, and if they are not the same, step S204 is executed.
Specifically, before step S202, the method further includes:
receiving a keep-alive packet which is sent by the target client terminal and contains a template class client configuration identifier and a strategy class client configuration identifier;
setting the value of the template class client configuration identifier in the configuration record as the value of the template class client configuration identifier in the keep-alive package, and setting the value of the policy class client configuration identifier in the configuration record as the value of the policy class client configuration identifier in the keep-alive package.
In this embodiment, a template class client configuration identifier and a policy class client configuration identifier are also set on the target client terminal, and in an initial state, both a value of the template class client configuration identifier and a value of the policy class client configuration identifier are 0. When the user modifies the client-side template class configuration and/or the client-side strategy class configuration on the target client terminal manually, modifying the values of the template class client configuration identifier and the strategy class client configuration identifier correspondingly; for example, if the user only modifies the client-side template class configuration, the value of the template class client configuration identifier is modified from 0 to 1, but the value of the policy class client configuration identifier is still 0.
Step S203: and comparing the client side template class configuration and the client side strategy class configuration which are updated to the local controller with the controller side configuration to determine the difference configuration under the condition that the value of the template class client configuration identifier is consistent with the value of the template class local configuration identifier and the value of the strategy class client configuration identifier is consistent with the value of the strategy class local configuration identifier.
Specifically, before step S203, the method further includes:
and when the target client terminal is registered to the controller, acquiring all the configurations on the target client terminal, and storing all the acquired configurations to the local controller.
It should be noted that, there are other configuration information besides the client-side template class configuration and the client-side policy class configuration on the target client terminal, and when the target client terminal is registered to the controller, all the configuration information on the target client terminal needs to be updated to the local controller
In this embodiment, if the value of the template class client configuration identifier is consistent with the value of the template class local configuration identifier, and the value of the policy class client configuration identifier is consistent with the value of the policy class local configuration identifier, it indicates that the client-side configuration currently on the target client terminal is consistent with the client-side configuration already existing locally in the controller, and the client-side configuration may be directly obtained locally from the controller to perform configuration comparison.
Step S204: under the condition that the value of the template client configuration identifier is inconsistent with the value of the template local configuration identifier, acquiring client template configuration currently on the target client terminal; and/or, under the condition that the value of the policy class client configuration identifier is inconsistent with the value of the policy class local configuration identifier, acquiring the client side policy class configuration currently on the target client terminal.
In this embodiment, when a certain type of client-side configuration changes, only this type of client-side configuration is obtained, thereby further reducing the time used for configuration comparison and the consumption of resources in the configuration comparison process.
Step S205: and updating the acquired client-side template type configuration and/or client-side strategy type configuration to the local controller.
Step S206: setting the value of the template class local configuration identifier as the value of the template class client configuration identifier, and setting the value of the strategy class local configuration identifier as the value of the strategy class client configuration identifier.
Step S207: and comparing the client side template class configuration and the client side strategy class configuration which are updated to the local controller with the controller side configuration to determine the difference configuration.
Therefore, whether the client-side template configuration and/or the client-side strategy configuration needs to be acquired from the target client terminal is determined by judging whether the values of the configuration identifiers are consistent; if the client side template configuration and the client side strategy configuration are consistent, the client side template configuration and the client side strategy configuration do not need to be acquired from the target client terminal, and therefore the technical problem that more resources are occupied in the configuration comparison process is solved; if the client-side template configuration and/or the client-side strategy configuration are not consistent, the client-side template configuration and/or the client-side strategy configuration can be acquired from the target client terminal in a targeted mode.
Step S208: and sending the difference configuration to the target client terminal.
In this embodiment, all the control side configurations do not need to be issued to the target client terminal, and only the differential configurations after configuration comparison need to be issued to the target client terminal, so that the resource occupation is reduced, and the configuration issuing efficiency is improved.
Specifically, after step S208, the method further includes:
and when the difference configuration is successfully sent to the target client terminal, setting the value of the template class controller configuration identifier as the value of the template class client configuration identifier, and setting the value of the strategy class controller configuration identifier as the value of the strategy class client configuration identifier.
It should be noted that, when the difference configuration is successfully sent to the target client terminal, the values of the template class controller configuration identifier, the template class client configuration identifier, and the template class local configuration identifier are consistent, and the values of the policy class controller configuration identifier, the policy class client configuration identifier, and the policy class local configuration identifier are consistent.
