Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a notification sending method, apparatus, network device, and storage medium. Background Technology

[0002] Network management devices can install, operate, and delete network device configurations, as well as obtain network device configuration and status information, through the Network Configuration Protocol (NETCONF) or the Representational State Transfer (RESTCONF) protocol. Specifically, the network configuration server within a network device can send a configuration change notification to network configuration clients in the network management device that have subscribed to configuration change notifications when the network device's configuration information changes. However, the configuration change notification sent by the network configuration server to the network configuration client typically contains a large amount of redundant information. The network configuration client also needs to process this redundant information, resulting in wasted communication resources and high communication and data processing pressure on the network management device. Summary of the Invention

[0003] This invention provides a notification sending method, apparatus, network device, and storage medium, aiming to reduce the communication pressure between the client and the network device.

[0004] In a first aspect, embodiments of the present invention provide a notification sending method applied to a network device, the method comprising:

[0005] The system receives a configuration change instruction sent by the first client and performs a corresponding configuration change operation according to the configuration change instruction to update the configuration information of the network device.

[0006] A configuration change notification is sent to the 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.

[0007] Secondly, embodiments of the present invention also provide a notification sending device, the notification sending device comprising:

[0008] The configuration update module 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;

[0009] The notification sending module is used to send a configuration change notification to the 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.

[0010] Thirdly, embodiments of the present invention also provide a network device, the network device including a processor, a memory, a computer program stored in the memory and executable by the processor, and a data bus for implementing connection communication between the processor and the memory, wherein when the computer program is executed by the processor, it implements the steps of any notification sending method provided in the embodiments of the present invention.

[0011] Fourthly, embodiments of the present invention also provide a storage medium for computer-readable storage, characterized in that the storage medium stores one or more programs, which can be executed by one or more processors to implement the steps of any notification sending method provided in the embodiments of the present invention.

[0012] This invention provides a notification sending method, apparatus, network device, and storage medium. The method involves receiving a configuration change instruction from a first client and performing a corresponding configuration change operation based on the instruction to update the network device's configuration information. A configuration change notification is then sent to a target client, which 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, lowering the communication pressure between the client and the network device, as well as the client's data processing pressure, and improving the communication efficiency between the client and the network device.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0022] It should be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. 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.

[0023] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating the steps of a notification sending method provided in an embodiment of the present invention.

[0025] This invention provides 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.

[0026] Please refer to Figure 2 , Figure 2 This is a schematic block diagram illustrating an application scenario of a notification sending method provided in an embodiment of the present invention.

[0027] like Figure 2 As shown, the configuration library in the 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 will send the configuration information change notification to the NETCONF client that has subscribed to the notification through the NETCONF server.

[0028] In related technologies, the Network Configuration Protocol (NETCONF) is a protocol that provides configuration management for network data devices, using Extensible Markup Language (XML) to transmit data and protocol information. The NETCONF server sends configuration change notifications to all NETCONF clients that have subscribed to the notification. However, the NETCONF client that caused the configuration change does not need to receive the configuration change notification to determine the network device's configuration change. If the NETCONF client that caused the configuration change has also subscribed to the configuration change notification, it will also receive the notification, making the configuration change notification redundant.

[0029] In the notification sending method provided in this application embodiment, 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, as well as the data processing pressure of the NETCONF client.

[0030] For example, the NETCONF client can be a network management device or a module within a network management device; no limitation is made here.

[0031] Understandable. Figure 2 This is merely an example of an embodiment of this application and does not limit the technical solution of this application. For example, the NETCONF server and NETCONF client can also be the RESTCONF server and RESTCONF client.

[0032] like Figure 1 As shown, the notification sending method includes steps S101 to S102.

[0033] Step S101: Receive the configuration change instruction sent by the first client, and perform the corresponding configuration change operation according to the configuration change instruction to update the configuration information of the network device.

[0034] For example, the first client sends a configuration change command to the network device, instructing the network device to perform a configuration change operation and update the configuration information in the network device's configuration library.

[0035] For example, the configuration change command can be the edit-config command, which edits the configuration information in the configuration library. Of course, it is not limited to this, and the configuration change command can also be other commands, which are not limited here.

[0036] Step S102: 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 that has subscribed to the configuration change notification.

[0037] For example, in response to a configuration change operation of a network device, the server in the network device will send a configuration change instruction to the client that has subscribed to the configuration change notification, so that the client that has subscribed to the configuration change notification will be informed in a timely manner that the network device configuration information has changed.

[0038] For example, since the change in configuration information is caused by a configuration change command from the first client, the first client is already aware of the configuration change in the network device during the interaction with the network device via the configuration change command. Therefore, the configuration change information sent to the first client is redundant.

[0039] For example, in order to avoid the first client receiving redundant configuration change notifications, in the notification sending method provided in this application, when the network device sends a configuration change notification to the target client in response to a change in configuration information, it identifies clients other than the first client that have subscribed to configuration change notifications as the target client.

[0040] For example, a configuration change notification is used to inform the target client in a timely manner that the configuration information of the network device has changed. The configuration change notification includes at least a configuration information name and configuration change information; wherein, the configuration information name is used to indicate which configuration information has been changed, and the configuration change information is used to indicate the specific content of the changed configuration information.

[0041] For example, since configuration change notifications that indicate changes in configuration information are not 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.

[0042] Please refer to Figure 3 , Figure 3 This is a flowchart illustrating the steps of a notification sending method according to another embodiment of the present invention.

[0043] like Figure 3As shown, 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 messages, and filters the first client when determining the target client to receive the configuration change notification based on the result of the message interaction.

[0044] For example, 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.

[0045] For example, the first client can interact with the server of the network device through messages, instructing the server to filter the first client when sending configuration change notifications.

[0046] Please refer to Figure 4 , Figure 4 A flowchart illustrating the sub-steps of a notification sending method according to another embodiment of the present invention.

[0047] like Figure 4 As shown, in some embodiments, the network device includes a server. Step S201 interacts with the first client via messages, and filters the first client when determining the target client to receive the configuration change notification based on the result of the message interaction. This includes: Step S2011a, sending a first message to the first client, the first message indicating the capability information supported by the server, the capability information indicated by the first message including the capability to filter 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 indicating the capability information available to the server, the capability information indicated by the second message including the capability to filter the first client when determining the target client to receive the configuration change notification.

[0048] For example, according to the NETCONF protocol, when a connection is established between a client and a server, both parties need to send HELLO messages to each other. The server and client determine their respective supported capabilities by sending HELLO messages to each other. If both parties' HELLO messages include the same capability information, an agreement can be reached to enable that capability.

[0049] For example, by adding capability information to the HELLO message 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.

[0050] For example, if the capability information indicated in the first HELLO message and the second HELLO message exchanged between the first client and the server both include the capability to filter the first client when determining the target client receiving the configuration change notification, the server can filter the first client when determining the target client through the interaction of HELLO messages.

[0051] For example, there is no limitation on the sending order of the first client and the server. It is possible that the first client sends the first message first, and the server sends the second message based on the first message; or the server sends the first message first, and the first client sends the second message based on the first message.

[0052] Specifically, by adding the following field to the HELLO messages exchanged 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> .

[0053] Please refer to Figure 5 , Figure 5 This is a flowchart illustrating the sub-steps of a notification sending method provided in another embodiment of the present invention.

[0054] like Figure 5 As shown, in some embodiments, the step of interacting with the first client via 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 includes: step S2011b, receiving a first subscription message sent by the first client, wherein 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 S2012b, sending a subscription success message to the first client based on the subscription message.

[0055] For example, the first client may also instruct the server to filter the first client when determining the target client to receive the configuration change notification in the subscription message when subscribing to the configuration change notification.

[0056] For example, the sending of configuration change notifications can be implemented using the YANG model. YANG is a data modeling language used to describe data models related to NETCONF network configurations and network states. YANG itself is not a data model, but rather a language for defining data models; a model built using the YANG language is simply called a YANG model. Therefore, subscription messages can be used to instruct the YANG model to filter the first client when determining the target client to receive the configuration change notification.

[0057] For example, by adding the following field to the subscription message, the YANG model can be instructed to filter the first client when determining the target client to receive configuration change notifications: <yangpush-dev:excluded-self-chang e xmlns:yangpush-dev="http: / / www.zte.com.cn / zxr10 / netconf / schema / rosng / yangpus h-dev"> enable.

[0058] For example, a successful subscription message confirms that the server has received the first subscription message and has successfully configured the system based on the first subscription message.

[0059] In some implementations, receiving the configuration change instruction sent by the first client includes: obtaining a first identifier of the first client based on the configuration change instruction; sending a configuration change notification to the target client according to the updated configuration information includes: determining the target identifier of the target client from a second identifier of clients that have subscribed to the configuration change notification, based on the first identifier.

[0060] For example, when a configuration change instruction is received, the first client that sent 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 received the configuration change message.

[0061] In some implementations, determining the target identifier of the target client from the second identifiers of clients that have subscribed to the configuration change notification based on the first identifier includes: determining the second identifier of the second client that has subscribed to the configuration change notification based on a preset notification subscription list; and determining the client identifiers other than the first identifier in the second identifier as the target identifier.

[0062] For example, 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 sending the configuration change notification according to the target identifier, it is only sent to clients other than the first client that have subscribed to the configuration change notification.

[0063] In some implementations, the method further includes: determining a notification subscription list based on a second subscription message sent by a second client, the notification subscription list including a second identifier of a second client that has subscribed to the configuration change notification.

[0064] For example, a NETCONF client subscribes to configuration change notifications from a NETCONF server in a network device via a subscription message. Here, "second client" refers to all NETCONF clients that have subscribed to configuration change notifications from the network device, and "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.

[0065] For example, the second subscription message can be the first subscription message used to instruct the server to filter when sending configuration change notifications, or it can be a regular subscription message other than the first subscription message; there is no limitation here.

[0066] For example, a network device can determine a notification subscription list based on the received second subscription message, so that when a configuration message changes subsequently, it can send a configuration change notification to the corresponding client based on the second identifier in the configuration list.

[0067] The notification sending method provided in the above embodiments receives a configuration change instruction sent by a first client, and performs a corresponding configuration change operation according to the configuration change instruction to update the configuration information of the network device; and sends 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. Since 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.

[0069] like Figure 6As shown, the notification sending device includes: a configuration update module 110 and a notification sending module 120.

[0070] The configuration update module 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;

[0071] The notification sending module is used to send a configuration change notification to the 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.
