Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The existing SDH equipment manufacturers have a plurality of independent network management systems, and operators can manage the SDH equipment by using a plurality of systems and cannot realize end-to-end service scheduling, so that the operation and maintenance difficulty of the operators is increased, which is a pain point of the operation and maintenance of the operators.
However, the introduction of the OSU technology provides new requirements for the management and control technology of the device, and an operator desires to define a set of standard southbound interfaces, so that the operator can complete operation and maintenance by using only one set of network management system, and can also implement end-to-end service scheduling. Therefore, the present application provides a method and an apparatus for implementing a southbound interface compatible with different YANG models, which addresses the problem in the prior art.
Fig. 1 shows a schematic flow diagram of a southbound interface implementation method compatible with different YANG models, which is provided by the present invention, and as shown in fig. 1, the southbound interface implementation method includes:
and S101, merging YANG models of different operators to obtain a target YANG model.
In this step, the operator refers to a provider providing network services, which is interdependent and corresponding to a manufacturer of the communication device, and the domestic operators include china mobile, china unicom, china telecom, china radio and television and a central communication network.
YANG (Yet Another Next Generation) is a data modeling language. The YANG model defines a hierarchical structure of data, and can be used for operation based on a Network Configuration (NETCONF) protocol, thereby implementing Configuration and status operation of the NETCONF to devices. The modeling objects of the YANG model include configuration, status data, remote procedure calls and notifications, which can describe all data sent between NETCONF client and server in a complete description, which is finally presented as a file suffixed with ". YANG".
In the communication field, usually, multiple operators may negotiate and establish a set of industry standard southbound interfaces, but because the requirements of each operator for equipment are different and not completely consistent, each operator may make some specific extensions on the basis of the set of industry standard southbound interfaces to form southbound interfaces meeting the respective enterprise standards, and these interfaces may be defined using a YANG model.
It can be understood that an operator wants that the same device of a device manufacturer can be compatible with a plurality of different operators to obtain the original YANG models corresponding to the applicable south-oriented interfaces of the different operators, and because the requirements of each operator on the device are different, the extensions made on the basis of the industry standard south-oriented interfaces are also different, so that the original YANG models of the different operators need to be merged, the YANG models of the different operators are merged into one YANG model which can be commonly used by the operators, and the merged YANG model is the target YANG model.
It should be noted that the merging of the YANG models of different operators is subject to the international standard IETF RFC 6020 for YANG, which specifically explains YANG's functions, modeling architecture, and file format.
And S102, according to the operator identification, realizing the southbound interface defined in the target YANG model through programming.
In this step, the operator identifier refers to an identifier used by each operator to distinguish the operator from other operators, and may be an english abbreviation of an operator name, or may be a custom description of different operators according to a preference, and may mainly distinguish the different operators. For example, the operator identities corresponding to the operators china mobile, china unicom and chinese telecom may be the acronyms of their english names, "CMCC", "CUCC" and "CTCC", respectively.
Code, which is encoded in a computer programming language, is the process of converting information from one form or format to another. The YANG files refer to files with ". YANG" as a suffix in the target YANG model, and are realized by encoding to define southbound interfaces applicable to different operators.
The southbound interface is a software interface, manages other manufacturers' network management or equipment through a NETCONF protocol, and can support various forms of interface protocols. In a popular way, the southbound interface performs various operations through a series of interfaces, so as to realize management of related equipment, wherein the series of interfaces involved are collectively called southbound interfaces. In terms of a topological structure, the management and control system is located above, the south-oriented interface is located below, and the north-up interface is located below the south-oriented interface, so that the management and control system is called as a south-oriented interface.
It will be appreciated that the YANG models of different carriers are merged into a target YANG model that includes a plurality of YANG files suffixed by ". YANG" to define the southbound interface applicable by the different carriers. After the target YANG model is obtained, according to the operator identification of each operator, all written codes are operated to realize the southbound interface in the target YANG model. Specifically, because the YANG models used by each operator are not completely the same, the target YANG model is realized according to the operator identifier of each operator, and it is ensured that the extended functions and the original general functions of each operator can be realized without omission, thereby ensuring that the southbound interface suitable for each specific operator can be normally installed in the subsequent practical application.
S103, installing a YANG model corresponding to an actual operator according to the operator identification and the target YANG model; the actual operator is one or more of the different operators.
And on the basis that the southbound interface defined in the target YANG model is realized in the last step, installing a YANG model corresponding to an actual operator according to the operator identification, wherein the actual operator needs to be the operator corresponding to different YANG models which are merged in advance, and the number of the actual operators can be one or more.
It is understood that the southbound interfaces are defined by YANG files, and that running the written program code is an implementation of YANG files, i.e., the southbound interfaces defined by these YANG files. And installing a YANG model corresponding to the actual operator according to the operator identification and the target YANG model, thereby realizing a standard southbound interface which can be compatible with YANG models of different operators.
In this embodiment, a target YANG model is obtained by combining YANG models of different operators, and a southbound interface defined in the target YANG model is implemented by using programming according to an operator identifier, and in actual application, a YANG model corresponding to an actual operator is installed according to the operator identifier of the actual operator and the implemented target YANG model. The method solves the problem that the same equipment of an equipment manufacturer is compatible with the pain points of a plurality of operator enterprise standard southbound interfaces, and greatly reduces the equipment version maintenance cost of the equipment manufacturer.
On the basis of the above embodiment, further, merging the YANG models of different operators to obtain the target YANG model, which includes: all operator identities corresponding to the YANG model to be merged are defined.
It can be understood that, before merging the YANG models of different operators, operator identifications corresponding to all the YANG models that need to be merged may be predefined, so that when the YANG models of different operators are merged, the different operators can be better distinguished, and especially, unique functions respectively extended by the different operators can be better distinguished.
In a specific embodiment, the operator identities of three operators of China Mobile, China Unicom and China telecom are defined, and the specific identities are "cmcc", "cucc" and "ctcc", respectively. Of course, according to the actual requirement, the identifier of other operators may be added thereto, and the definition manner is specifically as follows:
“feature cmcc{ description“cmcc” }
feature cucc{ description“cucc” }
feature ctcc{ description“ctcc” }”。
in the embodiment, before different YANG models are combined, operator identifications corresponding to different YANG models are defined, so that the YANG models of different operators can be combined better subsequently, southbound interfaces compatible with the YANG models of different operators are realized, pain points that the same equipment of an equipment manufacturer is compatible with multiple operator enterprise standard southbound interfaces are solved, and maintenance cost of equipment versions of the equipment manufacturer is reduced.
On the basis of the above embodiment, further, merging the YANG models of different operators to obtain a target YANG model, including: and if the YANG models to be merged expand new YANG files, merging the YANG models of different operators in a direct merging mode.
It will be appreciated that in merging the YANG models of different operators, first, the merging rules should follow the international standard IETF RFC 6020 for YANG; secondly, the YANG models of different operators are usually expanded based on the industry standard YANG model, the main contents of the YANG models are consistent, the expanded specific functions are different, and the YANG models are combined in different modes according to the actual expansion conditions of the operators.
When a new YANG file is expanded in the YANG models to be merged, the YANG models of different operators are merged by adopting a direct merging mode. Wherein, a new YANG file is expanded, including two cases: one is a new YANG file with a suffix of "Yang"; in addition, a remote procedure call function is added on the basis of the existing YANG file.
In a specific embodiment, FIG. 2 shows one of the expanded merged graphs of the different operator YANG models provided by the present invention. As shown in fig. 2, the ctcc (chinese telecom) newly expands the device upgrade function and the OSU function, which are defined by separate YANG files acc-file.yang and acc-osu.yang, respectively; cucc (china unicom) newly expands g.metro function, defined as a separate YANG file acc-gmetro.yang. In this case, the YANG model of china telecom and YANG model of china unicom with specific functions extended can be merged by direct merging.
In another embodiment, fig. 3 shows a second expanded merged graph of different operator YANG models provided by the present invention. As shown in fig. 3, cucc (china unicom) also extends a service interface of a Remote device, and adds a Remote Procedure Call (RPC) create-eth-to-eth-connection to an existing YANG file acc-eth. In this case, the YANG model of china unicom can be merged with other YANG models in a direct merging manner.
In this embodiment, if a new YANG file is extended in the YANG model to be merged, the YANG models of different operators are merged in a direct merging manner, which solves the problem that the same device of a device manufacturer is compatible with the pain points of multiple operator enterprise standard southbound interfaces, and greatly reduces the device version maintenance cost of the device manufacturer.
On the basis of the above embodiment, further, merging the YANG models of different operators to obtain a target YANG model, including: and if new fields or parameters are expanded in the YANG model to be merged, merging the YANG models of different operators by adopting a condition judgment mode in combination with the operator identification.
It can be understood that when new fields or parameters are expanded in the YANG models to be merged, the YANG models of different operators can be merged by adopting a conditional judgment mode according to predefined operator identifications. Common condition judgment includes an IF statement, which is a judgment statement, and judges whether an execution condition is satisfied according to an operator identifier, that is, IF the operator has a certain specific function, one of the given two operations is executed, otherwise, the other given operation is executed.
In a specific embodiment, fig. 4 shows a third expanded merged graph of different operator YANG models provided by the present invention. As shown in FIG. 4, on the basis of the existing YANG file, the node oam-state-pac is adjusted by cucc (China Unicom) according to its own needs, and further adjusted to oam-enable-pac, while the original oam-state-pac is still used by cmcc (China Mobile) and ctcc (China telecom). For the two nodes of oam-state-pac and oam-enable-pac, the operator id can be labeled by means of if-feature respectively, so as to distinguish different operators.
In this embodiment, IF a new field or parameter is extended in the YANG model to be merged, the YANG models of different operators are merged by combining with the operator identifier and adopting an IF statement condition judgment mode, and this merging mode solves the problem that the same device of a device manufacturer is compatible with the pain points of multiple operator enterprise standard southbound interfaces, thereby greatly reducing the device version maintenance cost of the device manufacturer.
On the basis of the above embodiment, further, merging the YANG models of different operators to obtain the target YANG model, further includes: if the YANG models to be merged use different methods to define the same type of enumeration, the YANG models of different operators are merged in a joint sharing mode.
It is understood that the YANG models of different operators can be merged in a joint sharing manner if the YANG models to be merged respectively use different methods to define the same type of enumeration. Wherein, different methods are used to define the same type of enumeration, and the final enumeration result is the same, but the enumeration mode is different. The enumeration type is a basic data type and is used for declaring a set of named constants, when a variable has several possible values, the variable can be defined as the enumeration type, and the joint sharing mode comprises merging in a UNION mode.
In one embodiment, FIG. 5 shows four expanded merged graphs of the different operator YANG models provided by the present invention. As shown in fig. 5, for the service-mapping-mode field in the node create-sdh-connection, it is an enumeration type, and specifically, cmcc (china mobile) and ctcc (china telecom) are defined by using enum and identity, respectively, in which case, the merging may be performed by using UNION.
Wherein enum and identity are two definitions of the same enumeration. For example, the original enumeration constants A, B and C are expanded by a new enumeration constant D, and if the enumeration is defined in an identity manner, only one more constant D needs to be assigned to a single position; if the definition is performed by enum, it is necessary to find the positions of the previous enumeration constants A, B and C and add the enumeration constant D thereafter. The two definitions differ, but the result is that four constants A, B, C and D are enumerated. It should also be noted that UNION is a special class, and is also a type of construction data structure. A number of different data types may be defined within a "UNION", such as enum and identity in this embodiment.
In this embodiment, if the YANG models to be merged respectively use different methods to define enumerations of the same type, the YANG models of different operators are merged in a joint sharing manner, and this merging manner solves the problem that the same device of a device manufacturer is compatible with pain points of multiple operator enterprise standard southbound interfaces, thereby greatly reducing the device version maintenance cost of the device manufacturer.
On the basis of the above embodiment, further, according to the operator identifier, the southbound interface defined in the target YANG model is implemented by programming, including: the target YANG model is provided with a digital label, and the digital label comprises an operator identifier, an equipment model, a serial number and a delivery date; and acquiring an operator identifier in the digital label, and realizing a southbound interface defined in the target YANG model through programming according to the operator identifier.
It can be understood that an individual digital label is set in the target YANG model, the digital label includes an operator identifier, an equipment model, an equipment serial number and an equipment delivery date, all nodes and methods of YANG files in the target YANG model are realized once by acquiring the operator identifier in the digital label and running a written program code according to the operator identifier, and it is ensured that each operation extended function and original general function can be realized without omission, thereby ensuring that a south-oriented interface suitable for each specific operator can be normally installed subsequently in practical application.
For example, FIG. 6 shows a schematic diagram of a digital label in the target YANG model provided by the present invention. As shown in fig. 6, the digital tag includes two parts, namely, an attribute and a value, where DeviceType is a device type, Vendor is a device manufacturer, MacAddress is a MAC address, HardwareVersion is a device hardware version, SoftwareVersion is a device software version, SerialNo is a device serial number, productondate is a production date of the device, and Telco is an operator identification field.
It should be further noted that, when the device leaves the factory, the corresponding operator identifier is set according to the actual situation, that is, only the Telco attribute of the digital tag needs to be changed.
In this embodiment, the operator identifier is obtained from the digital label, and according to the operator identifier, the southbound interface defined in the target YANG model is implemented by using programming, and the southbound interface included in the YANG file is correspondingly implemented. The problem that the same equipment of an equipment manufacturer is compatible with a plurality of operator enterprise standard southbound interfaces is solved, and the equipment version maintenance cost of the equipment manufacturer is greatly reduced.

The device solves the problem that the same equipment of an equipment manufacturer is compatible with the pain points of a plurality of operator enterprise standard southbound interfaces, and greatly reduces the equipment version maintenance cost of the equipment manufacturer.
