[0018] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, combined, or partially merged, so the actual execution order may vary depending on the actual situation.

[0020] It should be understood that the terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0021] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0022] Please refer to Figure 1, which is a schematic flow chart of the steps of a notification sending method provided in an embodiment of the present application.

[0023] Embodiments of the present application provide a notification sending method, apparatus, network device, and storage medium. The notification sending method can be applied to a network device that communicates with a network management device based on the Network Configuration Protocol (NETCONF) or the Representational State Transfer (RESTCONF) protocol.

[0024] Please refer to Figure 2, which is a schematic block diagram of an application scenario of a notification sending method provided in an embodiment of the present application.

[0025] As shown in Figure 2, the configuration repository in a network device is used to record the configuration information of the network device. When the configuration information of the network device changes, the network device sends a configuration information change notification to the NETCONF client that has subscribed to the notification through the NETCONF server.

[0026] In related technologies, the Network Configuration Protocol (NETCONF) is a protocol that provides configuration management for network data devices and uses Extensible Markup Language (XML) to transmit data and protocol information. A NETCONF server sends configuration change notifications to all NETCONF clients that have subscribed to the notifications. However, the NETCONF client that caused the configuration change does not need to use the configuration change notification to determine the configuration change status of the network device. If the NETCONF client that caused the configuration change also subscribes to configuration change notifications and also receives the configuration change notification, the configuration change notification is redundant information.

[0027] In the notification sending method provided in an embodiment of the present application, the configuration change notification to be sent is filtered by a notification filter, so that the NETCONF server will not send the configuration change notification to the NETCONF client that caused the change, thereby reducing the communication pressure between the NETCONF client and the network device and the data processing pressure of the NETCONF client.

[0028] Exemplarily, the NETCONF client may be a network management device or a module in the network management device, which is not limited here.

[0029] It is understandable that FIG2 is only an example of an embodiment of the present application and does not limit the technical solution of the present application. For example, the NETCONF server and the NETCONF client may also be a RESTCONF server and a RESTCONF client.

[0030] As shown in FIG1 , the notification sending method includes steps S101 to S102 .

[0031] Step S101: Receive a configuration change instruction sent by a first client, and perform a corresponding configuration change operation according to the configuration change instruction to update configuration information of the network device.

[0032] Exemplarily, the first client sends a configuration change instruction to the network device to instruct the network device to perform a configuration change operation and update the configuration information in the network device configuration library.

[0033] For example, the configuration change instruction may be an edit-config instruction, which is used to edit the configuration information in the configuration library. Of course, the present invention is not limited thereto, and the configuration change instruction may also be other instructions, which are not limited here.

[0034] Step S102: Send a configuration change notification to a target client according to the updated configuration information, wherein the target client is a client other than the first client that has subscribed to the configuration change notification.

[0035] Illustratively, in response to a configuration change operation of a network device, a server in the network device may send a configuration change instruction to a client that has subscribed to configuration change notifications, so that the client that has subscribed to configuration change notifications may be notified of changes to the network device configuration information in a timely manner.

[0036] For example, since the configuration information change is caused by a configuration change instruction from the first client, the first client has already learned about the configuration change of the network device during the interaction with the network device via the configuration change instruction. Therefore, the configuration change information sent to the first client is redundant information.

[0037] Exemplarily, in order to avoid the first client receiving redundant configuration change notifications, in the notification sending method provided in the present application, when the network device sends a configuration change notification to the target client in response to a change in configuration information, the client other than the first client that has subscribed to the configuration change notification is determined as the target client.

[0038] Exemplarily, the configuration change notification is used to promptly inform the target client of changes in the configuration information of the network device. The configuration change notification includes at least the configuration information name and configuration change information; wherein the configuration information name is used to indicate which configuration information has changed, and the configuration change information is used to indicate the specific content of the changed configuration information.

[0039] For example, since the configuration change notification of the configuration information change will not be sent to the first client that caused the change, the amount of redundant information received by the first client is reduced, the communication pressure between the client and the network device and the data processing pressure of the client are reduced, and the communication efficiency between the client and the network device is improved.

[0040] Please refer to FIG3 , which is a flowchart illustrating the steps of a notification sending method provided by another embodiment of the present application.

[0041] As shown in Figure 3, in some embodiments, the network device includes a server, and the method further includes step S201 before receiving the configuration change instruction sent by the first client: the server interacts with the first client through a message, and filters the first client when determining the target client to receive the configuration change notification based on the result of the message interaction.

[0042] Exemplarily, the sending of configuration change notifications is implemented by the server in the network device. When the configuration information of a node or node instance in the configuration library changes, the server generates a configuration change notification, converts the configuration change notification into a format that the client can recognize, and then sends it to the client.

[0043] Illustratively, the first client may interact with the server of the network device through messages, and instruct the server to filter the first client when sending configuration change notifications.

[0044] Please refer to FIG. 4 , which is a flowchart of sub-steps of a notification sending method provided in another embodiment of the present application.

[0045] As shown in Figure 4, in some embodiments, the network device includes a server, step S201 interacts with the first client through a message, and filters the first client when determining the target client to receive the configuration change notification based on the result of the message interaction, including: step S2011a, sending a first message to the first client, the first message is used to indicate capability information supported by the server, the capability information indicated by the first message includes the capability of filtering the first client when determining the target client to receive the configuration change notification; step S2012a, receiving a second message sent by the first client based on the first message, the second message is used to indicate the capability information available to the server, and the capability information indicated by the second message includes the capability of filtering the first client when determining the target client to receive the configuration change notification.

[0046] For example, according to the NETCONF protocol, when a client and server establish a connection, they must send HELLO messages to each other. The server and client use these HELLO messages to determine the capabilities they support. If both HELLO messages include the same capability information, they agree to enable that capability.

[0047] Exemplarily, by adding capability information to a HELLO message between the NETCONF server and the first NETCONF client, the NETCONF server is instructed to filter the first NETCONF client when determining a target NETCONF client to receive the configuration change notification.

[0048] For example, if the capability information indicated in the first HELLO message and the second HELLO message sent between the first client and the server includes the capability to filter the first client when determining the target client to receive the configuration change notification, the server can filter the first client when determining the target client through the interaction of the HELLO messages.

[0049] For example, the sending order of the first client and the server is not limited here. The first client may send the first message first, and the server may send the second message based on the first message; or the server may send the first message first, and the first client may send the second message based on the first message.

[0050] Specifically, by adding the following field to the HELLO message sent between the NETCONF server and the first NETCONF client, the NETCONF server is instructed to filter the first NETCONF client when determining the target NETCONF client to receive the configuration change notification: <capability>urn:ietf:params:netconf:capability:yangpush:selfexclude:1.0< / capability> .

[0051] Please refer to FIG. 5 , which is a flowchart of sub-steps of a notification sending method provided in another embodiment of the present application.

[0052] As shown in Figure 5, in some embodiments, the interaction with the first client through messages and filtering the first client when determining the target client to receive the configuration change notification based on the result of the message interaction include: step S2011b, receiving a first subscription message sent by the first client, the first subscription message is at least used to instruct the server to filter the first client when determining the target client to receive the configuration change notification; step 2012b, based on the subscription message, sending a subscription success message to the first client.

[0053] Exemplarily, the first client may also instruct the server to filter the first client when determining a target client to receive the configuration change notification, in a subscription message for subscribing to the configuration change notification to the server.

[0054] For example, the sending of configuration change notifications can be implemented using a YANG model. YANG is a data modeling language used to describe NETCONF-related network configuration and network status data models. YANG itself is not a data model, but rather a language for defining data models. Models built using the YANG language are referred to as YANG models. Therefore, a subscription message can be used to instruct the YANG model to filter the first client when determining the target client for receiving the configuration change notification.

[0055] Exemplarily, by adding the following field to the subscription message, the YANG model is instructed to filter the first client when determining the target client to receive the configuration change notification: <yangpush-dev:excluded-self-changexmlns:yangpush-dev="http: / / www.zte.com.cn / zxr10 / netconf / schema / rosng / yangpush-dev"> enable.

[0056] Exemplarily, it is determined through a subscription success message that the server has received the first subscription message and has successfully performed configuration according to the first subscription message.

[0057] In some embodiments, receiving a configuration change instruction sent by a first client includes: obtaining a first identifier of the first client based on the configuration change instruction; sending a configuration change notification to a target client based on the updated configuration information includes: determining a target identifier of the target client from a second identifier of a client that has subscribed to the configuration change notification based on the first identifier.

[0058] Exemplarily, when a configuration change instruction is received, the first client that sends the configuration change instruction is determined based on the first identifier of the first client in the configuration change instruction. Subsequently, when sending a configuration change message, the first identifier is filtered from the second identifier of the client that has subscribed to the configuration change notification to obtain the target identifier of the target client that receives the configuration change message.

[0059] In some embodiments, determining the target identifier of the target client from the second identifier of the client that subscribes to the configuration change notification based on the first identifier includes: determining the second identifier of the second client that subscribes to the configuration change notification based on a preset notification subscription list; and determining the client identifier other than the first identifier in the second identifier as the target identifier.

[0060] Exemplarily, when sending a configuration change notification caused by a configuration change instruction to the first client, the client identifier other than the first identifier in the second identifier is determined as the target identifier, so that when the configuration change notification is sent according to the target identifier, it is only sent to clients other than the first client that have subscribed to the configuration change notification.

[0061] In some implementations, the method further includes: determining a notification subscription list based on a second subscription message sent by the second client, wherein the notification subscription list includes a second identifier of the second client that has subscribed to the configuration change notification.

[0062] Exemplarily, a NETCONF client subscribes to configuration change notifications from a NETCONF server in a network device via a subscription message. The second client represents all NETCONF clients that have subscribed to configuration change notifications from the network device, and the second identifier is the client identifier of all NETCONF clients that have subscribed to configuration change notifications from the network device. It is understood that the second client includes the first client, and the second identifier includes the first identifier.

[0063] Illustratively, the second subscription message may be the first subscription message used to instruct the server to perform filtering when sending configuration change notifications, or may be a common subscription message other than the first subscription message, which is not limited here.

[0064] Exemplarily, the network device can determine a notification subscription list according to the received second subscription message, so that when a subsequent configuration message changes, a configuration change notification is sent to a corresponding client according to the second identifier in the configuration list.

[0065] The notification sending method provided in the above embodiment receives a configuration change instruction sent by a first client, executes a corresponding configuration change operation based on the configuration change instruction, and updates the configuration information of the network device; and sends a configuration change notification to a target client based on the updated configuration information, wherein the target client is a client other than the first client that has subscribed to the configuration change notification. Because the configuration change notification is not sent to the client that issued the configuration change instruction, the amount of redundant information received by the client is reduced, the communication pressure between the client and the network device and the data processing pressure on the client are reduced, and the communication efficiency between the client and the network device is improved.

[0066] Please refer to Figure 6, which is a schematic block diagram of a notification sending device provided in an embodiment of the present application. The notification sending device can be configured in a server or a terminal to execute the aforementioned notification sending method.

[0067] As shown in FIG6 , the notification sending device includes: a configuration updating module 110 and a notification sending module 120 .

[0068] The configuration update module 110 is used to receive a configuration change instruction sent by the first client and perform a corresponding configuration change operation according to the configuration change instruction to update the configuration information of the network device; the notification sending module 120 is used to send a configuration change notification to the target client according to the updated configuration information, wherein the target client is a client other than the first client and has subscribed to the configuration change notification.
