In the field of communication technology, Synchronous Digital Hierarchy (SDH) devices involve a large number of manufacturers, and each manufacturer has a separate network management system, so that an operator needs to use multiple sets of network management systems to manage the SDH devices.

For an Optical Transport Network (OTN) device based on an Optical Service Unit (OSU) technology, an operator also puts forward a new requirement on its management and control technology in order to solve its operation and maintenance pain. Operators hope to define a set of standard southbound interfaces, which are realized by various equipment manufacturers, so that the decoupling of management and control is realized, operators can use a set of network managers to complete operation and maintenance, and end-to-end service scheduling can be realized, so that the pain point of operation and maintenance is solved, and the operation and maintenance cost is reduced.
Because the requirements of each operator on the equipment are not completely consistent, each operator can expand the southbound interface to form a southbound interface meeting the requirements of the operator. Under the condition, the management and control system of the equipment manufacturer cannot simultaneously and compatibly operate the equipment with the south-oriented interfaces of different operator enterprise standards, and the decoupling of management and control cannot be completely achieved.

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.
In the prior art, decoupling of management and control cannot be completely achieved on optical transmission network equipment of each operator, which not only increases difficulty in end-to-end service scheduling for each operator, but also increases operation and maintenance costs of the optical transmission network equipment of each operator. Therefore, the embodiment of the invention provides a software defined network management and control method for optical transport network equipment.
Fig. 1 is a schematic flowchart of a software-defined network management and control method for an optical transport network device according to an embodiment of the present invention, as shown in fig. 1, the method includes:
s1, responding to a control operation of a user, acquiring optical transport network equipment to be controlled corresponding to the control operation, and determining an operator identifier corresponding to the optical transport network equipment to be controlled;
s2, displaying a control interface corresponding to the operator identification based on the comprehensive function information obtained by combining the function information of the optical transport network equipment controlled by different operators;
the management and control interface is used for providing a management and control operation result corresponding to the management and control operation for the user.
Specifically, in the method for controlling a software-defined network of an optical transport network device provided in the embodiment of the present invention, an execution main body is a software-defined network control system (hereinafter, referred to as a control system) of the optical transport network device, and the control system may be applied to manufacturers of the optical transport network device. The management and control system may be configured in a server, where the server may be a local server or a cloud server, and the local server may specifically be an intelligent device such as a computer, which is not specifically limited in the embodiment of the present invention.
It can be understood that an Optical Transport Network (OTN) device is a core device constituting an Optical Transport Network, and the OTN device implements a corresponding function based on an Optical Service Unit (OSU) technology. In the embodiment of the present invention, the OTN device performs management and control through a Software Defined Network (SDN), that is, a management and control system is constructed through the SDN.
Step S1 is executed first, and in response to the user' S management operation, the user may be a relevant person with the login authority of the management and control system, and the management and control operation may be an operation performed by the user on the management and control system. For example, the governing system may be configured with a display interface on which a user may perform governing operations.
The management and control operation may be an operation of the user on the optical transport network device to be managed, and may include operations of deleting, modifying, creating, and querying function information of the optical transport network device to be managed, which is not specifically limited herein.
Because each optical transport network device has a corresponding operator, the operators corresponding to different optical transport network devices may be the same or different. In order to distinguish different operators, different operator identifiers are configured for different operators in the embodiment of the invention. The configuration process is configured in advance. For example, the operators may include china mobile, china unicom, and china telecom, and the operator identities of the operators are cmcc, cucc, and ctcc, respectively.
Furthermore, in order to distinguish optical transport network devices managed and controlled by different operators, in the embodiment of the present invention, operator identifiers of corresponding operators are configured for the optical transport network devices managed and controlled by different operators. Therefore, after the management and control operation of the user is determined, the optical transport network device to be managed and controlled corresponding to the management and control operation can be determined, and then the operator identifier corresponding to the optical transport network device to be managed and controlled is determined.
Then, step S2 is executed, and a management and control interface corresponding to the operator identifier is displayed through the integrated function information obtained by combining the function information of the optical transport network devices managed by different operators.
Different operators can adopt the YANG model to manage and control when managing and controlling the function information of the optical transport network equipment, and define the corresponding function information of the optical transport network equipment through the YANG model. Here, different operators may use their respective YANG models to manage the functional information of the optical transport network devices. The function information of the optical transport network devices managed and controlled by different operators can be the same or different, and is set by each operator according to needs. Therefore, the YANG models used by different operators may be the same model or different models, and are not limited herein.
Where YANG is a data modeling voice and a non-tagged voice. The YANG model is a tree structure, which is a tree structure composed of a large number of nodes such as leaves (leaf), lists (list), leaf-lists (leaf-list), and containers (container) and used for describing function information of each optical transport network device, and each node has description information of related functions of the optical transport network device.
It is understood that the model parameters of the YANG model include leaf nodes, list nodes, leaf list nodes, container nodes, and description information of each node.
In order to improve compatibility of the management and control system with function information of optical transport network devices managed and controlled by different operators, the management and control system may be configured to manage and control integrated function information obtained by combining the function information of the optical transport network devices managed and controlled by different operators, and a combining mode may be set as required, for example, the function information of the optical transport network devices managed and controlled by different operators may be directly deduplicated, and information having differences is retained, thereby realizing combination of the function information of the optical transport network devices managed and controlled by different operators, and obtaining the integrated function information.
It can be understood that, improving the compatibility of the management and control system with the function information of the optical transport network devices managed by different operators can be equivalent to improving the compatibility of the management and control system with the YANG models adopted by the operators, and the management and control system can be configured with a comprehensive YANG model for managing and controlling the comprehensive function information through the comprehensive YANG model. The integrated YANG model can be obtained by combining YANG models adopted by different operators, the combination mode can be set according to needs, for example, the model parameters of the YANG models adopted by different operators can be directly subjected to de-duplication, the model parameters with differences are reserved, and then the combination of the YANG models is realized to obtain the integrated YANG model.
In addition, the determination of the integrated YANG model can be realized in other manners, and is not limited in any way.
After the integrated function information is determined, the management and control interface corresponding to the operator identifier may be displayed through the integrated function information, that is, the management and control interface corresponding to the operator identifier may be displayed through the integrated YANG model that manages and controls the integrated function information. The management and control interface is a display interface of the management and control system corresponding to an operator corresponding to the optical transport network device to be managed and controlled, and the display logic of the management and control interface can be dynamically adjusted through operator identification. That is, in the management and control system, each operator identifier and the display logic of the management and control interface corresponding to the operator identifier may be stored, and the display logic of the corresponding management and control interface may be obtained through query of the operator identifier.
In the embodiment of the invention, a management and control operation result corresponding to the management and control operation of the user can be displayed on the management and control interface. Namely, the management and control interface is used for providing a management and control operation result corresponding to the management and control operation of the user.
Since the comprehensive function information managed by the management and control system is obtained by combining the function information of the optical transmission network devices managed by each operator, the management and control system can manage and control the optical transmission network devices corresponding to each operator, that is, a user can operate each optical transmission network device to be managed and controlled on the management and control system through management and control operation, and obtain a management and control operation result. That is, due to the configuration of the integrated YANG model in the management and control system, it can be ensured that the management and control interface corresponding to the operator identifier can be normally displayed.
The software defined network management and control method of the optical transport network equipment provided by the embodiment of the invention firstly responds to the management and control operation of a user, acquires the optical transport network equipment to be managed and controlled corresponding to the management and control operation, and determines the operator identification corresponding to the optical transport network equipment to be managed and controlled; and then displaying a control interface corresponding to the operator identification based on the comprehensive function information obtained by combining the function information of the optical transport network equipment controlled by different operators, and providing a control operation result corresponding to the control operation for the user through the control interface. The method adopts the comprehensive function information, can ensure that the optical transmission network equipment controlled by different operators is compatibly controlled, improves the compatibility of the optical transmission network equipment control, not only can ensure that each operator can completely decouple the optical transmission network equipment control, but also can greatly reduce the difficulty of realizing end-to-end service scheduling of each operator, reduce the operation and maintenance cost of each operator on the optical transmission network equipment, and simultaneously solve the requirement that an equipment manufacturer control system is compatible with different operator enterprise standard southward interfaces.
On the basis of the foregoing embodiment, in the software-defined network management and control method for an optical transport network device provided in the embodiment of the present invention, the method for determining integrated function information includes:
determining the same information and the difference information in the function information of the optical transport network equipment managed and controlled by different operators; the difference information comprises function difference information and parameter type definition difference information;
determining an operator identifier of a target operator corresponding to the function difference information, and labeling the function difference information by adopting the operator identifier of the target operator;
and representing the parameter type definition difference information by adopting compatible definition information, and combining the same information, the labeled function difference information and the definition information to obtain the comprehensive function information.
Specifically, in the embodiment of the present invention, when determining the integrated function information, that is, when merging the function information of the optical transport network devices managed and controlled by different operators, the same information and the different information in the function information of the optical transport network devices managed and controlled by different operators may be determined first. The same information refers to the same information that the optical transport network devices managed and controlled by different operators have, and the different information refers to different function information that the optical transport network devices managed and controlled by different operators have. Here, the same information and the different information may be determined by comparing the function information of the optical transport network devices managed and controlled by different operators.
The difference information may be divided into function difference information and parameter type definition difference information according to the type, and the function difference information may be different depending on the function, such as the presence or absence of a certain function, and different fields, different parameters, and the like related to the same function. The parameter type definition difference information may be different in parameter type definition, for example, different definition modes for the same parameter type in the function information of the optical transport network devices managed and controlled by different operators, and the like.
After that, the operator identifier of the target operator corresponding to the function difference information may be determined, and then, the function difference information may be labeled by using the operator identifier of the target operator. For example, for a certain function, the optical transport network device managed by the operator a has the function, and the optical transport network device managed by the operator B does not have the function, the target operator corresponding to the function difference information is the operator B, and if the operator B is the chinese telecom, the operator identifier of the target operator is ctcc. Further, this function can be labeled with ctcc.
Finally, the parameter type definition difference information is represented by common body (unity) definition information, for example, for different definition modes of the same parameter type, the common body definition information capable of compatibly defining the difference information may be represented, that is, in the function information of the optical transport network device managed and controlled by each operator, the same parameter type defined by different definition modes is uniformly defined by a unity definition mode.
And merging the same information, the labeled function difference information and the community definition information to obtain comprehensive function information.
In the embodiment of the invention, when the comprehensive function information is determined, the label of the operator identifier is introduced, so that the personalized information corresponding to each operator in the comprehensive function information can be distinguished, and the comprehensive function information can be ensured to be suitable for controlling the optical transmission network equipment controlled by each operator.
On the basis of the foregoing embodiment, in the software-defined network management and control method for an optical transport network device provided in the embodiment of the present invention, the function difference information includes at least one of service operation container function information, remote procedure call function information, function field information, and function parameter information; the parameter type definition difference information comprises different definition modes of enumeration parameters of the same type.
Specifically, in the embodiment of the present invention, the difference information included in the function information of the optical transport network device managed and controlled by different operators may be obtained by extending industry standard function information of the optical transport network device by each operator. From the perspective of the YANG model, the YANG model adopted by each operator is expanded based on the standard YANG model of the industry, and the main content is consistent, but specific functions are expanded. The standard YANG model refers to a model compliant with the international standard IETF RFC 6020 YANG. The international standard IETF RFC 6020YANG is a NETCONF Data Modeling Language (A Data Modeling Language for the Network Configuration Protocol (NETCONF)).
Further, the function difference information may include at least one of service operation container function information, remote procedure call function information, function field information, and function parameter information; the parameter type definition difference information includes different definition ways of enumeration parameters of the same type.
For example, for any operator, if function information of the optical transport network device managed by the any operator is compared with industry standard function information, the function information of the newly added service operation container and/or the Remote Procedure Call function information, that is, a YANG model adopted by the any operator is compared with a standard YANG model, and a service operation container (container) and/or a Remote Procedure Call (RPC) of the newly added root node are/is added, when determining the comprehensive function information, the function information of the newly added service operation container and/or the Remote Procedure Call function information are/is labeled by using an operator identifier corresponding to the any operator, that is, when determining the comprehensive YANG model, the service operation container and/or the Remote Procedure Call of the newly added root node in the YANG model adopted by the any operator are labeled.
The labeling manner can be set according to needs, and is not particularly limited herein.
As shown in fig. 2, if any one of the carriers is chinese telecommunications, the corresponding carrier is identified as ctcc, and the YANG model used by the carrier extends the device upgrade function and the OSU function based on the standard YANG model, and is defined by separate YANG files (e.g., acc-file. Therefore, when determining the comprehensive YANG model, the Container and RPC defined in the YANG file included in the comprehensive YANG model are marked with the operator identifier ctcc.
If any operator is china unicom, the corresponding operator is identified as cucc, and the YANG model used by the operator expands g.metro function on the basis of the standard YANG model, and is also defined by a separate YANG file (for example, acc-gmetro.yang). Therefore, when determining the comprehensive YANG model, the Container and RPC defined in the YANG file included in the comprehensive YANG model are marked with the operator identification cucc.
As shown in fig. 3, if any operator is china unicom, the YANG model used by the operator expands the remote device service interface based on the standard YANG model, and adds RPC, i.e., create-eth-to-eth-connection, in the existing YANG file (acc-eth). Therefore, when determining the comprehensive YANG model, the RPC newly added in the YANG file (acc-eth) included in the comprehensive YANG model needs to be labeled with the operator identity cucc.
For another example, for any operator, if the function information of the optical transport network device managed by the any operator is compared with the industry standard function information, adding new function field information and/or function parameter information in the original service operation container and/or the original remote procedure call, that is, adding new fields and/or new parameters in the original service operation container and/or the original remote procedure call by using a YANG model adopted by the any operator as compared with the standard YANG model, when determining the comprehensive function information, marking the new function field information and/or function parameter information by using an operator identifier corresponding to the any operator, that is, when determining the comprehensive YANG model, marking the new fields and/or new parameters in the YANG model adopted by the any operator. The labeling manner can be set according to needs, and is not particularly limited herein.
As shown in fig. 4, on the basis of the standard YANG model, china unicom adjusts the node oam-state-pac according to its own needs to be oam-enable-pac, and china mobile and china telecom still use the original oam-state-pac. Therefore, when determining the integrated YANG model, the two nodes included in the integrated YANG model need to be labeled with the operator identifiers cucc, cmcc, and ctcc, respectively.
In this embodiment of the present invention, the parameter type definition difference information may include different definition modes of enumerated parameters of the same type. That is, because the enumeration definition is various, in the YANG model adopted by different operators, the same type of enumeration parameters may be defined in different definition manners. Therefore, when this occurs, the same type of enumeration parameters can be defined in a compatible definition mode of a common body, so as to ensure the compatibility of the definition mode. Where a common bank can store different data types, but only one of them at a time. The length of the community is the length of the largest member.
As shown in fig. 5, the service-mapping-mode parameter in the create-sdh-connection is enumerated, and china mobile and china telecom are defined by using enum and identity, respectively, in which case, a common entity may be used for definition.
In the embodiment of the invention, not only the specific content of the function difference information and the parameter type definition difference information is given, but also the processing method for defining enumerations of the same type by adopting different definition modes is given, so that the personalized function information of each operator in the comprehensive function information, namely the personalized information of each operator in the comprehensive YANG model can be distinguished, and the comprehensive function information and the comprehensive YANG model can be ensured to be suitable for each operator.
On the basis of the foregoing embodiment, the method for managing and controlling a software-defined network of an optical transport network device according to an embodiment of the present invention, where marking the function difference information by using the operator identifier of the target operator includes:
and marking the function difference information by adopting the operator identification of the target operator based on the if-feature statement.
Specifically, in the embodiment of the present invention, during the annotation, an if-feature statement is used for implementation. Here, the operator id corresponding to each operator is defined by feature statement, for example, the following:
Figure BDA0003503962070000131
thereafter, the labeling of the operator identification is realized by an if-feature statement, as shown in fig. 4 and 5.
In the embodiment of the invention, the label of the operator identification is realized by adopting the if-feature statement, so that the label process can be simplified, and the guarantee can be provided for the comprehensive function information and the comprehensive YANG model to be suitable for each operator.
On the basis of the foregoing embodiment, in the software-defined network management and control method for an optical transport network device provided in the embodiment of the present invention, the operator identifier is obtained by pre-configuring based on an online mode of the optical transport network device to be managed when the dynamic host configuration protocol is automatically online, or by pre-configuring based on an adding operation of the optical transport network device to be managed in a software-defined network management and control system of the optical transport network device.
Specifically, in the embodiment of the present invention, the operator identifier corresponding to the optical transport network device to be controlled may be obtained by pre-configuration in an online manner when the optical transport network device to be controlled is automatically online according to a dynamic host configuration protocol, or may be obtained by pre-configuration in an adding operation of the optical transport network device to be controlled in a software defined network management and control system of the optical transport network device.
Because each operator sets different online modes of the optical transport Network device when a Dynamic Host Configuration Protocol (DHCP) is automatically online, for example, china mobile uses a Callhome mode defined by IETF RFC 6241 Network Configuration Protocol (Network Configuration Protocol) to automatically online; china telecom uses private TCP protocol to automatically go on-line; china unicom only uses DHCP protocol for automatic online.
Therefore, the corresponding operator can be automatically determined through the management and control system through the online mode of the optical transport network device to be managed during automatic online, and then the corresponding operator identification is determined.
In addition, when the user manually adds the optical transport network device to be controlled to the control system, the user manually designates the corresponding operator, and then determines the corresponding operator identifier.
In the embodiment of the invention, when the corresponding operator identifier is configured for the optical transmission network equipment to be controlled, the operator identifier can be manually realized by a user or automatically realized by a control system, so that the operator identifier and the optical transmission network equipment can be successfully bound.
On the basis of the foregoing embodiment, the software-defined network management and control method for an optical transport network device according to an embodiment of the present invention is a method for displaying a management and control interface corresponding to an operator identifier based on integrated function information obtained by combining function information of optical transport network devices managed by different operators, where the method includes:
the management and control of the comprehensive function information are realized through a software defined network management and control system of the optical transport network equipment;
correspondingly, the displaying the management and control interface corresponding to the operator identifier based on the comprehensive function information obtained by combining the function information of the optical transport network devices managed by different operators includes:
and displaying the control interface through the software defined network control system.
Specifically, in the embodiment of the present invention, before displaying the management and control interface corresponding to the operator identifier, the management and control system is required to implement management and control of the integrated function information, that is, after determining the integrated function information, the function node and the method corresponding to the integrated YANG model are implemented, and the integrated function information is managed and controlled through the integrated YANG model.
On this basis, the management and control interface corresponding to the operator identifier is displayed through the management and control system, and then the management and control system can be guaranteed to have the function of displaying the management and control interface corresponding to the operator identifier.
