Description

Data processing method, related device and computer storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a data processing method, a related apparatus, and a computer storage medium.

Background

In the field of operators, especially devices currently being served in networks, most network elements are configured functionally through a Command Line Interface (CLI), which may also be referred to as a command interface instance or command interface. With the development of Software Defined Network (SDN) technology, operators want to manage network elements through an SDN controller or an Element Management System (EMS).

In order to implement automatic function configuration and operation maintenance of a network element, an SDN controller or an EMS system needs to use a Command Object Interface (COI), which may also be referred to as an object interface instance or an object interface. Therefore, how to convert the command type interface expression of the network device into the object type interface expression which can be identified by the upper layer network element is one of the main problems to be solved by the SDN controller/EMS system.

To solve the above problems, the conversion from the command-type interface expression instance to the object-type interface expression instance is mainly realized by the research and development personnel manually developing codes one by one command. In practice, it is found that for different manufacturers and different network devices, if the above schemes are adopted, the labor cost is undoubtedly increased, the operation is complicated, the development cycle of the interface function is prolonged, and the research and development efficiency is reduced.

Detailed Description

Embodiments of the present invention will be described below with reference to the accompanying drawings.

First, some technical terms or technical concepts related to the present application are introduced.

Interface expression (interface expression), also known as syntax. Refers to the way in which both the provider and the user agree to define the interface. In general, the interface expression includes information such as an interface name, related parameters of the interface, and constraints. The same interface may use different interface expressions, which are different in format, to define or configure the functions of the interface. For example, IETF standards are typically expressed as interfaces via the YANG format using the Netconf protocol interface. Before the YANG interface expression, manufacturers mostly adopt XML schema as the interface expression of the Netconf protocol interface.

For example, the interface expression is implemented, for example, with the following code:

{ interface name: sendamassage;

parameter 1: AA name, type: string;

parameter 2: message, type: string }.

In other words, the present application may describe an interface expression in a textual manner.

Interface instance (interface instance) refers to a way to implement interface expression by program code, for example, referring to an interface expression example, and its corresponding interface instance is: sendAMessage { "AA 1" "Hello World! "}. This is an example of an interface in pseudo-code.

A Command Line (CLI), also called a command interface instance (command interface instance), may also be referred to as a command interface. It consists of several commands, different commands being used to implement different functions. Examples of imperative interfaces for sendamaessage are as follows:

sendAAMessage AA1 message“Hello World！”

the sendAMessage and the message are command words in the command, and the command words consist of English characters and numbers in a fixed sequence or English characters and part of special characters in the fixed sequence. AA1 and Hello World are parameters in the command.

A command interface expression (command interface expression) is used to describe an expression manner of a command interface, for example, a sendamaessage command interface is expressed by a command interface as follows:

sendAAMessage<AAname#STRING>

message<#STRING>

a Command Object Interface (COI), also called object interface instance, is called an object interface (object interface instance), which is simply called an object interface. It can define each thing in the interface as an object, and express the characteristics and behavior of the interface through the attributes and behavior of the object. For example, in sendamaessage, the object is "AA", the behavior is "message", and the object-based interface is aa1.sendmessage ("Hello World!")

An object expression (object expression) refers to an expression manner describing an object interface, for example, an object interface expression expressing an object interface aa1.sendmessage is as follows:

it should be noted that, for the convenience of description, the present application will collectively refer to "command interface, command interface expression, and command interface instance" as "command interface expression instance CLI". In some cases, "CLI" as referred to below in this application may refer to any of a imperative interface expression, imperative interface, or imperative interface instance. Similarly, for the convenience of description, the present application will collectively refer to "object-based interface, object-based interface expression, and object-based interface instance" as "object-based interface expression instance COI". In some cases, a "COI" referred to below in this application may refer to any of an object-wise interface expression, an object-wise interface, or an object-wise interface instance.

An SDN controller (SDN controller) refers to a software system capable of intelligently controlling and managing network traffic in a software-defined network.

Element Management System (EMS) refers to a system for managing and configuring network devices (also network elements) in an operator network.

A northbound interface (NBI) refers to an interface that is provided by a control device upwards to an Operation Support System (OSS) of another vendor or operator for access or management. The control device refers to a device for controlling and managing a network device, and may be, for example, an SDN controller, an EMS system, or other management device.

A southbound interface (SBI) refers to an interface for a control device to go down for managing network devices.

In order to solve the problems of complex operation, long research and development period, low efficiency and the like existing in the prior art for achieving object-type interface expression conversion from a command-type interface table, the application provides another data processing method, a network framework applicable to the method and related equipment. Fig. 1 is a schematic diagram of a network framework of a communication system according to an embodiment of the present invention. The communication system 100 shown in fig. 1 includes: an Operation Support System (OSS) 102, a control device 104, and a network device 106. Wherein the OSS102 may communicate with the network device 106 via the control device 104. For example, the OSS102 sends a configuration command to the network device 106 through the control device to configure the related functions of the network device. Alternatively, the OSS102 may send an inquiry command to the network device 106 via the control device to inquire about the related functions that the network device has. Illustratively, taking a network device as a router as an example, the OSS may configure a routing path or a routing function of the router by a configuration command, and the like.

The control device 104 is configured to communicate with the OSS102 and the network device 106, respectively. In particular, the control device 104 communicates with the OSS102 via a northbound interface. The control device 104 communicates with the network device 106 via a southbound interface. Optionally, the northbound interface supports object-based interface expressions and the southbound interface supports command-based interface expressions.

In the present application, the control device 104 is also used to implement data conversion between the southbound interface and the northbound interface. Because the south interface and the north interface respectively support different data formats (or data expression forms) for transmission; or the respective supported and identified data formats of the OSS and the network device are different, and the control device 104 needs to perform data conversion in order to implement normal communication of data. For example, the control device 104 receives a configuration command sent by the OSS102 in the form of an object-based interface expression over the northbound interface, and only supports the form of an object-based interface expression instance because the network device 106 does not support identifying the configuration command in the form of an object-based interface expression instance. Therefore, the control device 104 needs to convert the configuration command in the form of the object-type interface expression instance into the configuration command in the form of the command-type interface expression instance, so as to send the converted configuration command to the network device 106, thereby implementing the function configuration at the network device 106 side.

It should be noted that, in the following, the present application takes as an example a conversion device, which is specifically used for implementing data conversion between the south-oriented interface and the north-oriented interface. In practical applications, the conversion device may specifically be a software device or a hardware device deployed in the control device 102, or may also be the control device 102 itself, which is not limited in this application.

The network device 106 is a physical entity connected to the network, and in practical applications, the network device 106 may specifically include, but is not limited to, a switch, a router, a gateway, a bridge, and a network card.

Fig. 2 is a schematic flow chart of a data processing method according to an embodiment of the present invention. The method as shown in fig. 2 comprises the following implementation steps:

step S201, the conversion device obtains a command type interface expression instance CLI of the network device, where the CLI records a configuration function of the network device that the southbound interface supports identification, and the southbound interface refers to an interface used when the conversion device communicates with the network device.

In the present application, when the network device is used for the first time or the configuration function of the network device is updated, the conversion device needs to obtain the CLI of the network device. Taking the network device for the first time as an example, when detecting that the network device enters the network or enters the communication system, the conversion device may obtain a CLI of the network device, where the CLI is provided by a device vendor of the network device and is used to describe all or part of configuration functions supported by the network device, and the configuration functions are described by specifically using an example of command type interface expression.

The CLI describes an object expressed by a imperative interface, the attributes of the object, and the relationship between any two objects. The number of objects included in the CLI is not limited, and may include one or more. Relationships between objects, hereinafter referred to simply as object relationships, refer to relationships that exist between two objects, including but not limited to containment and association relationships, and there may be differences in the definition or representation in the CLI for different object relationships. Exemplarily, a relation between two objects can be defined as an inclusion relation by a keyword @ include in the CLI; the relationship between two objects is defined as an association relationship by defining the attribute type of an object as the REF type, and so on.

In the present application, the object relationship is used to indicate the configuration order of the command lines related to the object, that is, the configuration order of the functions configuring the object. Taking the object relationship as the inclusion relationship as an example, the present application needs to define the included object as a child object of the included object, and the included object needs to be issued before the included object. If the object relationship is taken as the association relationship, the application needs to add the attribute information of the associated object to the attribute information of the associated object, and the associated object needs to be issued before the associated object.

Step S202, the conversion equipment converts the CLI into an object type interface expression instance COI according to a pre-stored first conversion rule, wherein the COI records the configuration function of the network equipment supported and identified by the northbound interface, and the northbound interface refers to the interface supported and communicated with the OSS in the conversion equipment. The first conversion rule is pre-stored in the conversion equipment and is used for realizing mapping conversion from the command type interface expression instance CLI to the object type interface expression instance COI.

Wherein, the first conversion rule is presented in the form of configuration file, and at this time, it can also be referred to as B description file. The first conversion rule is used for implementing the mapping conversion from the CLI to the COI, and may specifically include, but is not limited to, at least one of the following information: the corresponding relation between the command key and the object, the attribute information of the object, the relation between the object and the like. The attribute information of the object refers to information for describing the attribute of the object, such as an object name, an object number, and the like. In practical applications, the attribute information of an object is further divided into a primary key attribute and a non-primary key attribute, where the primary key attribute refers to information for describing a key attribute of the object, such as a constraint condition of the object, an object identifier of the object, or other custom-set key attribute information. Non-primary key attributes refer to information that describes the non-important, secondary attributes of an object, such as the number of rows of the command line occupied by the object.

The first conversion rule may be specifically provided by a device provider of the network device, or customized by an operator development team, and may be stored in the conversion device in advance. In practical applications, the first transformation rule and the imperative interface expression instance CLI may be merged and exist in the form of a configuration file, which is specifically exemplified in the following of the present application.

Please refer to fig. 3, which illustrates a schematic view of a scenario. In the scenario shown in fig. 3, for example, the conversion device is deployed in an SDN controller, the SDN controller includes a south interface and a north interface, where the south interface refers to a communication interface used when the conversion device communicates with an upper-layer OSS system, and the north interface refers to a communication interface used when the conversion device communicates with a network device. As shown in the figure, the conversion device includes a grammar recognition module and an interface conversion module. The grammar recognition module is used for defining the stage of designing the interface expression example, the input of the grammar recognition module can be a command type interface expression example CLI and a B description file (a first conversion rule), and the output is an object type interface expression example COI. Alternatively, the grammar recognition module may support multiple object-based interface expression languages, i.e., support different grammar conversions. For example, an object-based interface expression of a YANG model, a YAML model, or a java API is supported, where object semantics of respective expression instances of the YANG model, the YAML model, and the java API are the same, but syntax is different, and a format of an object-based interface expression instance generated by output is also different. Therefore, for the object-type interface expression examples with different formats, the grammar recognition module needs to design or use different interface expression example conversion algorithms (or conversion rules).

Specifically, after the conversion device obtains the CLI and B description files, the syntax recognition module may perform syntax recognition on the input CLI and B description files according to a preset syntax rule to obtain object information included therein, where the object information includes, but is not limited to, at least one object, attribute information of each object, object relationship, and the like. Further, the conversion device generates the COI based on the obtained object information, and optionally may also obtain a second conversion rule, where the second conversion rule is used to implement mapping conversion of the COI to the CLI. In practical application, the second conversion rule may also be presented in the form of a configuration file or a mapping table, that is, the second conversion rule may be loaded in the configuration file or the mapping table, and the second conversion rule at least includes information such as a correspondence between an object and a command keyword, an attribute of the object, and an object relationship.

Alternatively, the first conversion rule and the second conversion rule related to the present application may be separately presented in the form of a configuration file, or may be presented in the form of one configuration file. When they are presented in the form of a configuration file, the conversion device may implement interconversion between the COI and the CLI based on the configuration file including the first conversion rule and the second conversion rule, which is not limited in this application.

The interface conversion module is used for realizing the conversion from the object type interface expression instance COI to the command type interface expression instance CLI, and optionally also used for realizing the conversion from the CLI to the COI. Namely, the interface conversion module is used for realizing the conversion between the CLI and the COI.

In an alternative embodiment, the OSS system supports the identification and issuing of commands in the form of object-based interface expression instances, COIs. For example, the OSS system may issue configuration commands in the form of object-based interface expression instances COI to the translation device. Correspondingly, the conversion equipment receives the COI configuration command issued by the OSS, and further converts the COI configuration command according to the first conversion rule to obtain the CLI configuration command. The configuration command is used to instruct the configuration of the function of the network device, such as the configuration of the functions of the routing load, routing path, and the like. The translation device then forwards the CLI-form configuration command to the network device. Correspondingly, the network equipment receives the configuration command in the form of CLI, and completes the function configuration indicated by the configuration command to the network equipment according to the configuration command in the form of CLI.

As another example, a query command is taken as an example. The OSS system may issue a query command in the form of a COI to the translation device, where the query command is used to query the configuration function of the network device. Accordingly, the translation device receives the query command in the form of the COI. Further, the translation device may respond to the query command in the COI format to obtain the configuration function of the network device requested to be queried by the query command. Specifically, since the network device cannot support the query command in the COI format, the conversion device needs to convert the query command in the COI format into the query command in the CLI format according to the first conversion rule, and then issues the query command to the network device. Accordingly, the network device receives and responds to the query command in the form of the CLI, and obtains the configuration function related to the network device requested by the query command. Similarly, the network device returns a response message in the form of CLI to the translation device, where the response message carries the relevant configuration function of the network device requested by the query command. After receiving the CLI-form response message, the conversion device may convert the CLI-form response message into a COI-form response message for direct return to the OSS system. In practical application, the response message in the form of the COI may be presented in the form of a configuration file, where the configuration file includes information such as an object, an attribute of the object, and an object relationship, and the application is not limited in this application.

Optionally, to save latency and improve data processing efficiency, the conversion device may obtain all or part of configuration functions supported by the network device from the network device in advance, and these configuration functions are all fed back to the conversion device in the form of CLI. Optionally, in order to improve the efficiency of information reporting, the conversion device may convert the obtained configuration function of the network device in the CLI form into a configuration function in the COI form (specifically, information such as an object and an attribute of the object), so as to store the configuration function in the conversion device. Correspondingly, when the conversion device receives a query command in the COI form issued by the OSS, the conversion device can directly obtain the configuration function of the network device in the COI form related to the query command from the local database, and then return the configuration function to the OSS system to complete the related query of the query command.

In practical applications, after receiving the CLI-form configuration function sent by the network device, the conversion device may store a CLI-form function configuration file in a local database, where all or part of the configuration functions supported by the network device are recorded in the function configuration file. Correspondingly, after receiving the query command in the COI form, the conversion device may obtain the function configuration file in the CLI form related to the query command, and further convert the function configuration file in the CLI form into the function configuration file in the COI form to send to the OSS system.

Optionally, to save data processing delay, the conversion device may also convert the CLI-form configuration function file into a COI-form configuration function file to be stored in its local database. Accordingly, after receiving the query command in the COI form, the conversion device can acquire the functional configuration file in the COI form related to the query command from the local database so as to directly send the functional configuration file to the OSS system, thereby improving the data processing efficiency.

It should be noted that, in the present application, the network device side may use the same expression example to describe the configuration functions supported by each of the configuration command and the query command. For example, as shown in fig. 4A and 4B, a command-based interface representation instance CLI is used to display or describe configuration functions corresponding to configuration commands and query commands supported by the router device. Fig. 4A specifically shows a configuration command in the form of CLI to implement the relevant functional configuration of the router device. The display result of the query configuration command is specifically shown in fig. 4B. As can be seen from fig. 4A and 4B, the functional configurations in the display results of the configuration command in the CLI form and the query configuration command are both described by CLI.

For a better understanding of the present invention, the following description is given by way of example. Specifically, the transformation device may receive a command type interface expression instance CLI provided by a network device provider, receive a B description file (i.e., a first transformation rule) provided by the network device provider or an operator northbound interface development team. The B description file at least comprises the mapping conversion relation between the CIL and the COI. In practical applications, the original CLI and B profiles are usually unified, for example, unified is defined as profile x. After the conversion equipment obtains the X.beyond file, the syntax recognition module carries out syntax recognition on the X.beyond file according to a preset syntax rule so as to obtain object information in the file, wherein the object information comprises but is not limited to an object, attributes of the object, object relations and other information.

Exemplarily, a code diagram of an x.beyond file is shown in fig. 5A. As shown in fig. 5A, the conversion device identifies a command keyword in an x.beyond file according to a preset grammar rule, and determines an object, an attribute of the object, an object relationship, and other information included in the file. For example, in fig. 5A, the conversion apparatus may recognize @ mo as a command keyword as one object. Likewise, the relevant command line referred to by @ mo is attributed to the relevant configuration command for the object. The attribute of the main key of the object is represented by @ key, the attribute in the other command line related to the command key is identified as the other attribute of the object, and information such as the corresponding relation between the object and the command key and the attribute of the object is recorded.

In the recognition process, the conversion apparatus may also obtain the object relationship in the x. Specifically, the conversion device may identify the object relationship as an inclusion relationship by the keyword @ includeby, for example, another object B is associated by @ includeby in the object a, which indicates that a and B are inclusion relationships, a is an included object, B is an included object, and a included object is a child object containing the object B. The conversion apparatus may identify the object relationship as the association relationship by the attribute type of the object being the REF type, for example, if the type of the attribute (i.e., command parameter) included in one object a is defined as the REF type, and the attribute of another object B is defined in the REF type, the object a and the object B are the association relationship, the object a is the association object, and the object B is the associated object, and at this time, the attribute defined in the REF of the associated object B may be added in the object a as the association attribute of the object a. Optionally, after obtaining the object relationship, the conversion device may record a configuration sequence of the command line indicated by the object relationship, that is, a sequence of configuring a configuration function of the network device, where a specific associated object needs to be issued before an associated object, and a containing object needs to be issued before an contained object.

Accordingly, after obtaining the object information in the x.beyond file, the conversion apparatus may obtain a second conversion rule, where the second conversion rule at least includes a mapping conversion relationship between the COI to the CLI. Further, after the conversion device obtains the object information, an object-based interface expression instance COI corresponding to the CLI may be generated, and a syntax format of the COI is not limited, for example, a YANG model syntax or a java API syntax. For example, referring to the example of fig. 5A, the conversion apparatus generates the object-based interface expression instance COI expressed in YANG format as shown in fig. 5B from the x.beyond file shown in fig. 5A. As shown in fig. 5A and 5B, the bold-faced keywords are in one-to-one correspondence, and the code bold-faced keywords in fig. 5B are generated according to the corresponding keyword codes in the x.beyond file shown in fig. 5A, for example, the @ mo system in fig. 5A corresponds to the binder system in fig. 5B, and the system is an object.

In the actual operation process of the conversion device, the conversion device receives a configuration command in the form of an object-oriented interface expression instance COI issued by the OSS system through a northbound interface, and specifically shows a configuration command code for creating an l3vpn interface expression instance with reference to fig. 6. After the conversion device receives the configuration command in the form of COI, referring to the second conversion rule obtained in the x.beyond file in fig. 5A, the two objects included in fig. 6 and the command line to which each object relates can be obtained, where there are a first object ip vpn-instance @ mo (l3vpn) and the command line therebelow, a second object interface @ mo (l3vpn-sap) and the command line therebelow, respectively. Referring to fig. 5A, it can be known that the object relationship between the first object and the second object is an inclusion relationship, the conversion device may determine that the command line related to the first object needs to be issued first, and then the command line related to the second object needs to be issued later. Further, the conversion device generates a configuration command in the form of a command type interface expression instance CIL according to the object obtained by identification and the command line of each object (the command line includes information such as the attribute of the object), specifically, as shown in fig. 7, configuration command codes in the form of CLI are provided, so that the network device can create an l3vpn interface directly according to the configuration command in the form of CLI.

By implementing the embodiment of the invention, the problems of longer research and development period, higher cost, lower efficiency and the like of the object type interface expression conversion from the command type interface table in the prior art can be solved, the object type interface expression examples in various formats can be automatically generated according to different grammar conversion and conversion rules aiming at the input of the same command type interface expression example, different program codes do not need to be manually designed aiming at different format grammars, the development cost and the development period are reduced, and the development efficiency is improved.

The following describes the relevant apparatus to which the present invention relates, in conjunction with the foregoing description of the embodiment described in connection with fig. 1-7. Fig. 8 is a schematic structural diagram of a conversion apparatus according to an embodiment of the present invention. Applied to a communication system including a network device, a conversion device and an operation support system OSS, the conversion device 800 shown in fig. 8 includes a communication module 802 and a processing module 804.
