Detailed ways

The embodiments of this application are applied to network devices, network equipment, network systems that make up SDN, or any system that can execute the embodiments of this application. The following explains some terms in this application for the convenience of those skilled in the art understand. It should be noted that when the solutions of the embodiments of this application are applied to a network system, or any system that can execute the embodiments of this application, the names of the network devices and network equipment may change, but this does not affect the implementation of this application. Example of the implementation of the program.

1). Network equipment refers to equipment used for network data transmission, such as switches, routers, etc.

2). NETCONF is a network configuration management protocol based on Extensible Markup Language (XML). NETCONF provides a mechanism for managing network equipment. Users can use this mechanism to add, modify, and delete network equipment. Configure to obtain configuration and status information of network devices. NETCONF adopts the client/server model (Client/Server, C/S). In the NETCONF-based configuration management model, the Client corresponds to the management device, and the Server corresponds to the network device. Through the NETCONF-based configuration management model, it is possible to manage the device Data exchange with network equipment.

NETCONF has a four-layer structure, namely, the Secure Transport Layer, the Message Layer, the Operation Layer, and the Content Layer.

Among them, the secure transport layer is used to specify a secure encrypted communication protocol and perform data transmission.

The message layer is used to implement message sending and receiving between Client and Server.

The operation layer is used to implement specific command operations of the Client on the Server based on the message layer, such as query, edit, copy, delete, etc.

3). The content layer is used to define the specific protocol content. The content layer is the most important layer in NETCONF. The content layer in NETCONF is open, that is, NETCONF itself does not specify a specific data structure for the content layer, but through another next generation (Yet Another Next Generation, YANG) modeling The language models the data structure to define the specific content of the content layer of the NETCONF protocol. Therefore, users can establish a YANG data model according to their needs to realize the management of network devices on the server side. When NETCONF needs to be extended and modified, it can be realized by modifying the YANG data model. Therefore, the configuration management model based on NETCONF has better scalability and management efficiency.

4) Protocol (Protocol Buffers) is an efficient structured data storage method that can be used to serialize data, that is, to convert data structures or objects into a format that can be stored and transmitted (such as network transmission). Many advantages such as cross-platform, high efficiency, and good scalability. Through Protobuf, data structure modeling and conversion can be achieved.

5) "Multiple" means two or more than two, and other measure words are similar. "And/or" describes the association relationship of the associated objects, indicating that there can be three types of relationships, for example, A and/or B, which can mean: A alone exists, A and B exist at the same time, and B exists alone. The character "/" generally indicates that the associated objects before and after are in an "or" relationship.

6) "Correspondence" can refer to an association relationship or binding relationship, and the correspondence between A and B means that there is an association relationship or binding relationship between A and B.

It should be pointed out that the terms or terms involved in the embodiments of the present application can be referred to each other, and will not be repeated here.

FIG. 1 is a schematic diagram of a network architecture provided by an embodiment of the application. The network architecture shown in Figure 1 includes: a management device 11, a network device 12, a network device 13, and a network device 14. The management device 11 forms a network with the network device 12, the network device 13, and the network device 14. The management device 11 passes NETCONF The protocol performs configuration management on the network device 12, the network device 13, and the network device 14. Among them, the network device 12 and the network device 13 are configuration management models based on a YANG data model, and the network device 14 is a configuration management model based on a non-YANG data model, for example, a configuration management model based on CLI.

FIG. 2 is a schematic diagram 1 of an application scenario provided by an embodiment of the application. As shown in FIG. 2, under the network architecture shown in FIG. 1, the management device 11 sends a message request message to the network device 12 and the network device 13 to characterize the interaction instruction, because the network device 12 and the network device 13 are both based on The configuration management model of the YANG data model. Therefore, the network device 12 and the network device 13 can directly recognize and respond to the message request message, and return the message response message to the management device 11 to complete the management device 11 and the network device 12 and network device 13's data interaction process.

FIG. 3 is a second schematic diagram of an application scenario provided by an embodiment of the application. As shown in FIG. 3, under the network architecture shown in FIG. 1, the management device 11 sends a message request message to the network device 14 to represent an interactive instruction. Since the network device 14 is a configuration management model based on a non-YANG data model, Therefore, the network device 14 cannot directly recognize and respond to the message request message. It needs to parse the message request message first to execute the corresponding interactive instruction. After the execution is completed, the response result is again converted into data that conforms to the YANG data model. , And return to the management device 11 as a message response message to complete the data interaction process between the management device 11 and the network device 14.

In the application scenario provided by the embodiment shown in FIG. 3, because the configuration management model of the network device does not match the configuration management model of the management device, it is necessary to convert the data and instructions in the data interaction process between the management device and the network device. Because the configuration management model of the YANG data model is more flexible, when the operation instructions in the configuration management model based on the YANG data model are converted to the operation instructions in the configuration management model based on the non-YANG data model, some complex operation instructions cannot be realized. For example, the operation instruction in the configuration management model based on the YANG data model is "Query the description information of all the interfaces that are 10GE and the status is up". Because the operation instruction set in the configuration management model based on CLI is fixed, so The inability to implement the above-mentioned operation instructions causes the problems of low configuration management efficiency and low flexibility of use.

At the same time, when querying and copying network devices will produce a large amount of response results, the response results need to be converted to data that conforms to the YANG data model before they can be returned to the management device, and the compilation process consumes a lot of computing time. , Thus causing the problem of high response delay.

FIG. 4 is a schematic flowchart of a message processing method provided by an embodiment of the application. Illustratively, the message processing method provided in this embodiment is applied to a network device. As shown in FIG. 4, the method includes:

S101. Receive a message request message from the management device, where the message request message is text information based on the YANG data model.

Exemplarily, the management device may be a network management device, such as a network management server, a network management terminal, etc., network management software is installed in the network management device, and the user can configure and manage network devices in the same network through the network management software, such as configuration Data query, configuration data modification, configuration data replication, configuration data deletion, etc. The management device may also be a controller device or other devices that function as a controller, which can run a controller program and perform configuration management on network devices in the same network. The specific form of the management device is not limited here.

Exemplarily, the network device may be a switch, router, or other access network device. The management equipment and the network equipment exchange data through the NETCONF protocol based on the YANG data model.

When the management device needs to perform configuration management on the network device, it sends a message-based request message to the network device. The message request message is used to characterize specific configuration management instructions and content, such as querying interface types and modifying interface names. The network device can receive the message request message and respond according to the configuration management instruction and content represented by the message request message.

Exemplarily, the message request message includes instruction information and content information corresponding to the instruction information. For example, the message request message is used to characterize an instruction to modify an interface name, and the interface name eth1 is eth0. Among them, the instruction information in the message request message is to modify the interface, and the content information is eth1 and eth2. Of course, it can be understood that the implementation manner of the message request message for modifying the interface name here is exemplary, and various other manners may also be used, which are not limited herein.

The message request message is text information based on the YANG data model, such as an XML file, or an Object Notation (JavaScript Object Notation, JSON) file, or other data exchange formats that meet specific specifications for storing and representing data and information, here There is no specific limitation.

S102. Determine a data object corresponding to the message request message according to the pre-stored data set, where the data set includes one or more data objects, and the data objects are data based on the Protobuf data model.

Exemplarily, the pre-stored data set may include two types of state data and configuration data, where the state data may be inherent attribute data of the network device and current operating state data, for example, the type of port, the state of the port, and the like. Status data can only be queried. The configuration data may be data configured by the user on the network device in a certain way, for example, the name of the port and the description of the port. The configuration data may also have multiple sub-data sets, and each sub-data set may be, for example, a database. For example, the <running/> database can be used to store the configuration data that is currently in effect; the <candidate/> database can be used to store the configuration data that can be submitted as effective; the <startup/> database can be used to store the configuration data at startup. The sum of status data and configuration data can be collectively referred to as a data set.

The data object is the basic unit of the data collection, for example, the type of the port, the state of the port, the name of the port, the description of the port, and so on. Different data objects can correspond to status data or configuration data. According to the configuration management instruction and content specifically characterized by the message request message, the corresponding data object can be determined. For example, the configuration management instruction and content represented by the message request message is to query the port type of port A, then the data object A corresponding to the message request message is the port type of the port; for another example, the message request message represents The configuration management instruction and content of is to query the description information of all interfaces that are 10GE and the state is up, then the data object A corresponding to the message request message is the description information of the interface that is 10GE and the state is up.

The data object is the data based on the Protobuf data model. Among them, the Protobuf data model has a mapping relationship with the YANG data model. The Protobuf data model is a preset data model for storing data collections, which can realize some or all of the features of the YANG data model.

Specifically, as an efficient method for serializing structured data, Protobuf can construct a Protobuf data model according to specific needs, so that the original data can be organized according to the Protobuf data model to form data based on the Protobuf data model.

In order to achieve model matching between the Protobuf data model and the YANG data model, it is necessary to establish the mapping relationship between the Protobuf data model and the YANG data model according to the characteristics of the YANG data model in advance. More specifically, YANG provides some basic data structures, such as module, container, and leaf. These basic data structures constitute the data structure of the YANG data model. When establishing the mapping relationship between the Protobuf data model and the YANG data model, the data structure provided by Protobuf can be used to map the data structure of the YANG data model. For example: Declare the package provided by Protobuf and the module provided by YANG as a mapping; declare the message provided by Protobuf and the container provided by YANG as a mapping; declare the field provided by Protobuf and the leaf provided by YANG as a mapping. The specific mapping method between the Protobuf data model and the YANG data model can be specifically set according to requirements, and there is no restriction here.

According to the mapping between the Protobuf data model and the YANG data model, the data object based on the Protobuf data model and the message request message based on the YANG data model can form a corresponding data model, and then determine the correspondence with the message request message The data object.

S103. Determine the data object corresponding to the message request message as the message response message, and send the message response message to the management device.

After determining the data object corresponding to the message request message, since the data format of the data object based on the Protobuf data model corresponds to the data format of the message response message based on the YANG data model, the data object can be directly used as the message response message Send to the management device to realize the response to the message request message sent by the management device, and then realize the data interaction process between the management device and the network device.

Exemplarily, the data object and the message response message may be an XML file or other data exchange format that conforms to a specific specification for storing and representing data and information.

The following describes the message processing method provided in this embodiment with a specific usage scenario.

The management device is a network management device. The network management device and the network device are in the same network. The network management device sends a message request message to the network device according to the NETCONF protocol based on the YANG data model. The message request message represents the port to port A. Type the instruction to query. The network device receives the message request message sent by the network management device. The network device stores a data set based on the Protobuf data model, and the data set includes multiple data objects. Since the characteristics of the Protobuf data model and the YANG data model are unified, the network device can directly determine the corresponding data object based on the Protobuf data model according to the message request message based on the YANG data model, and then combine the data object based on the Protobuf data model , In the form of XML files, return to the network management equipment, avoiding the conversion process between different data formats during the data interaction process between the network management equipment and the network equipment.

In this embodiment, the message request message is received from the management device, where the message request message is text information based on the YANG data model; the data object corresponding to the message request message is determined according to the pre-stored data set, where: The data set includes one or more data objects, which are data based on the Protobuf data model; the data object corresponding to the message request message is determined as the message response message, and the message response message is sent to the management device. Since the YANG data model and the Protobuf data model have corresponding data structures, the characteristics of the YANG data model can also be reflected in the Protobuf data model, and the management device can configure the network device through the message request message based on the YANG data model During management, it can give full play to the flexible and efficient advantages of the YANG data model, realize complex operation instructions such as compound condition query, and improve the efficiency and flexibility of configuration management. At the same time, since the conversion between different message data formats during the message transmission process between the management device and the network device is avoided, the efficiency of message transmission is improved, and the response delay of the network device is reduced.

FIG. 5 is a schematic flowchart of another message processing method provided by an embodiment of the application. As shown in FIG. 5, the method includes:

S201. Convert each sub-object in each memory object into each data value combination according to a pre-stored mapping file, where the mapping file is used to indicate the conversion relationship between the sub-object and the data value combination, and the data value The combination is a data expression based on the Protobuf data model.

Exemplarily, a memory object refers to data that exists in the memory in a specific data format after the network device is running. Each memory object includes a set of data, which is used to characterize different configuration data, for example, port speed. The memory object includes one or more sub-objects, and the sub-objects are used to represent more detailed configuration data. For example, the memory object PORT_SPEED is a port rate. For a network device, it usually has multiple different port rates, for example, a first port rate and a second port rate. The first port rate and the second port rate are sub-objects of the memory object. The collection of multiple sub-objects constitutes a memory object corresponding to a data object.

The data value combination is a data expression based on the Protobuf data model, that is, data that conforms to the Protobuf data model. According to the pre-stored mapping file, each sub-object in the memory object can be converted into a data value combination that conforms to the Protobuf data model, and then realize Convert memory objects into data conforming to the Protobuf data model.

Fig. 6 is a schematic diagram of the conversion of a memory object provided by an embodiment of the application. As shown in Fig. 6, Fig. 6 shows the process of converting each sub-object in the memory object into each data value combination in step S201. The specific data model of the object is determined by the network device. For network devices that use different configuration management models, the data model of the memory object storing configuration data is different. Through a specific mapping relationship, the memory object can be transformed into a unified For data that conform to the Protobuf data model, the Protobuf data model corresponds to the YANG data model. The specific mapping relationship can be obtained through a pre-stored mapping file.

S202: Generate each data object according to the pre-stored first model file and each data value combination, where the first model file is a file based on the Protobuf data model.

Specifically, the first model file is a description file of the Protobuf data model. According to the first model file, the specific data structure of the Protobuf data model can be determined, and the Protobuf data model has a mapping relationship with the YANG data model. According to the specific content of the first data value combination, for example, the first port rate is 1000; the second port rate is 1200; the third port rate is 1500, correspondingly generate the first port rate and the second port rate that conform to the Protobuf data model , The data object of the second port rate, and the specific data values 1000, 1200, 1500 are respectively assigned to the first port rate, the second port rate, and the second port rate in the data object representing the port rate, so as to realize the generation of each The purpose of the data object corresponding to the memory object is to complete the conversion of memory objects with different data structures to data objects based on the Protobuf data model.

S203. Receive a message request message from the management device, where the message request message is text information based on the YANG data model.

Exemplarily, this step may refer to step S101 shown in FIG. 4, which will not be repeated.

S204. Determine a data object corresponding to the message request message according to the pre-stored data set, where the data set includes one or more data objects, and the data objects are data based on the Protobuf data model.

After the network device is turned on, the network device converts the memory object running in the memory into a data object based on the Protobuf data model according to the preset mapping file and the preset first model file, that is, caches. The Protobuf data model and the YANG data model are unified in data structure and correspond in function. Optionally, this process may occur in the initialization phase after the network device is turned on, or under other triggering conditions, which is not specifically limited here.

The network management device sends a message request message to the network device according to the NETCONF protocol based on the YANG data model. The message request message represents an instruction to query the port type of port A. The network device receives the message request message sent by the network management device, and a data set based on the Protobuf data model is cached in the network device, and the data set includes multiple data objects. Since the characteristics of the Protobuf data model and the YANG data model are unified, the network device can directly determine the corresponding data object based on the Protobuf data model according to the message request message based on the YANG data model, and then combine the data object based on the Protobuf data model , In the form of XML files, return to the network management equipment, avoiding the conversion process between different data formats during the data interaction process between the network management equipment and the network equipment.

In this embodiment, by converting each sub-object in each memory object into each data value combination according to a pre-stored mapping file, the mapping file is used to indicate the conversion between the sub-object and the data value combination Relationship, the data value combination is a data expression based on the Protobuf data model; each data object is generated according to the pre-stored first model file and each data value combination, where the first model file is a file based on the Protobuf data model; received from Manage the device's message request message and respond to it. Because before receiving the message request message from the management device and responding, the memory object in the network device is converted into a data object based on the Protobuf data model, and the data object based on the Protobuf data model and the message request based on the YANG data model The data structure of the message has a corresponding relationship. Therefore, the network device can access the data object according to the message request message, which avoids that the network device needs to first respond to the message request message and the message response message when receiving and responding to the message request message. The problem of conversion improves the efficiency and flexibility of network equipment configuration management, and reduces the response delay of network equipment.
