It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0062] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims. In the description of the present application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and do not have to be used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0063] OTN, optical transport network, is a type of network that implements the transmission, multiplexing, routing, and monitoring of service signals in the optical domain and ensures their performance indicators and survivability.

[0064] SDH (Synchronous Digital Hierarchy), according to the definition of ITU-T recommendations, is a technical system that provides information structures of corresponding levels for the transmission of digital signals of different rates, including multiplexing methods and mapping methods, as well as related synchronization methods.

[0065] XML, Extensible Markup Language, is a subset of the Standard Generalized Markup Language. It can be used to mark data and define data types. It is a source language that allows users to define their own markup languages. XML is a standard generalized markup language with good extensibility, separation of content and form, strict syntax requirements, and good value preservation.

[0066] The NMS system is an operation and maintenance center responsible for equipment fault diagnosis and operation and maintenance, network operation and management of the wireless access system, and providing data and statistics for network management and planning.

[0067] QName (Qualified Name) is simply a member name with a namespace added. QName comes from XML and is composed of an XML namespace and an XML element name. The format is a namespace prefix, a colon (:), and an element name (local name).

[0068] UInt8 is an 8-bit (1-byte) unsigned integer type that can represent 0 to 255. In programming, uint8 is often used to represent the color value of a pixel, some binary data, or a counter with limited size.

[0069] UInt16 is a 16-bit (2-byte) unsigned integer type that can represent 0 to 65535. In programming, uint16 is often used to process larger binary data, port numbers in network communications, and other occasions that require 16-bit values.

[0070] See also Figure 1 As shown, the present invention provides a method for configuring SDH services of an OTN device based on netconfig, comprising:

[0071] S1: receiving the SDH service model and SDH service configuration data input by the user interface, including:

[0072] First, an SDH service configuration interface is sent to the user interface. After the user selects an SDH service model on the SDH service configuration interface, different SDH service configuration scenarios are dynamically configured according to the SDH service model selected by the user, and common data items under the SDH service configuration scenario are automatically filled in, and data items excluding the common data items are taken as data items to be input.

[0073] Then, an SDH service scenario data interface is sent to the user interface. The SDH service scenario data interface is used by the user to input the above-mentioned data items that need to be input. Common data items will not be displayed on the SDH service scenario data interface, which greatly reduces the data items that the user needs to input, thereby reducing errors caused by manual data input by the user, and can also simplify the configuration process and improve the efficiency and accuracy of SDH service configuration.

[0074] See also Figure 2-5 As shown in the figure, it is the SDH service configuration scenario data interface, where Figure 2 Configure the SDH service scenario data interface corresponding to the bidirectional non-protection for SDH services. Figure 3 Configure the SDH service scenario data interface corresponding to msp-1-plus-1 bidirectional protection for SDH services. Figure 4 Configure the SDH service scenario data interface corresponding to UNI protection for SDH services. Figure 5Configure the SDH service scenario data interface corresponding to NNI band protection for the SDH service; the SDH service scenario data interface includes SDH service label data, mapping mode, client-side data and network-side data, which are SDH service configuration data that need to be input by the user. The SDH service label data is related to the SDH service and is used to identify the SDH service data.

[0075] See also Figure 2-4 As shown, in the SDH service scenario data interface, the client side data includes: client side protection type, client side slot, client side port, client side first data type (vcType) and client side information mapping (mappingPath); the network side data includes: network side protection type, network side main line slot, network side main line port, network side main line mapping time slot, network side adaptation type (adaptationType), network side payload type (oduSignalType), network side switching capability (switchCapability), network side first data type (sdhType), network side second data type (vcType) and network side information mapping (mappingPath); different SDH service scenarios are determined by selecting the client side protection type and the network side protection type. Figure 5 and Figure 2-4 The difference is that the network side data also includes the network side spare line slot, the network side spare line port and the network side mapping time slot.

[0076] By making the SDH service configuration interface and performing real-time error correction and verification, the input of service configuration data items is greatly reduced, allowing network administrators to focus on filling in SDH service configuration data items. Combined with the data template obtained based on the SDH service model, the target XML data message sent is more accurate and less prone to errors, thereby greatly reducing errors in manual assembly.

[0077] Further, the target data input by the user in the SDH service scenario data interface is verified. First, it is determined whether the target data input by the user is complete. If the input is incomplete, the missing input data items are sent to the SDH service scenario data interface; then the target data input by the user is verified in real time, and the data items with incorrect input and the reasons for the incorrect input are output to prompt the user to correct the incorrectly input data items. Only after all data items in all SDH service scenario data interfaces are correctly input, the target data is determined as SDH service configuration data; see Figure 2 As shown in the figure, when the data entered by the user in the SDH service scenario data interface is verified in real time, if no data item filling error is found, no error prompt will be given; see Figure 3-5As shown, when a data item is filled in incorrectly, the verification result is sent to the SDH business scenario data interface. In the figure, an error occurs in the customer-side information mapping (mappingPath). By displaying "Input format is illegal! Example: 1-1-1-1" below the incorrectly filled data item, the user is reminded to modify the data item and how to modify it.

[0078] S2: Determine a data template according to the SDH service model, specifically:

[0079] The SDH service models include bidirectional without protection, msp-1-plus-1 bidirectional with protection, UNI with protection and NNI with protection. The SDH service configuration scenario is determined according to the SDH service model, and then different data templates are dynamically configured according to different SDH service configuration scenarios. Each SDH service configuration scenario corresponds to a data template.

[0080] S3: Determine the target data message according to the SDH service configuration data and data template, specifically:

[0081] The data template is an XML data template. After the XML data template is filled with the SDH service configuration data entered by the user, it is automatically assembled into a target XML data message. At this time, the assembled data is the verified SDH service configuration data, so there is no need to verify it again during assembly, avoiding the verification of the SDH service configuration data when generating the target XML data message. When an error is found in the data item and needs to be corrected, it jumps back to the SDH service configuration scenario data interface, which will reduce the configuration efficiency of the SDH service.

[0082] During the SDH service configuration process, the front-end and back-end of the configuration system use the http communication protocol. The data transmitted during the communication process is in json format. When the back-end receives the json format from the front-end, it is automatically assembled into a json object. Since the configuration system has realized the mutual conversion between yang module definition and data type in the early stage, it only needs to instantiate the corresponding configured data instance with the parameters received by the back-end, and then convert it into an XML string that meets the data requirements of the OTN equipment to obtain the target data message.

[0083] S4: Determine the SDH service configuration result according to the target data message, including:

[0084] Trigger the establishment of a network configuration (netconf) session to complete the network protocol (SSH) connection; and confirm the identity and authority of the OTN device; then exchange functions and operations with the OTN device whose identity and authority have been confirmed, that is, negotiate capabilities with the OTN device to understand the functions and operations supported by the OTN device and determine the connection method with the OTN device, thereby ensuring the functional operations that can be performed during the configuration process to establish a connection for communication with the OTN device.

[0085] After establishing a connection for communication with the OTN device, a target request (rpc request) with a target XML data message is sent to the OTN device; after the OTN device receives the target request (rpc request) with the target XML data message, a target result is generated according to the target XML data message; and an SDH service configuration result is determined according to the target result.

[0086] Before communicating with OTN devices, it is necessary to determine the yang model corresponding to the OTN device that needs to communicate, that is, the target model, and perform object conversion according to the target model (yang model) and convert it into the corresponding yang module data type definition, that is, convert the definition data of the target model (yang model) into the corresponding target data type.

[0087] The target data types after conversion include four types: public class, enumeration class, interface class and module class; the corresponding relationship between the definition data of the target model (yang model) and the target data type during the conversion process is as follows:

[0088] When the definition data is the first data, the corresponding target data type is a public class, and the first data is the common class data in the target model (yang model), for example, QName, UInt8, UInt16, etc.

[0089] When the definition data is the second data, the corresponding target data type is an enumeration class, and the second data is the "type enumeration" (enumeration type) defined by the target model (yang model).

[0090] When the definition data is the third data, the corresponding target data type is the interface class, and the third data is the "identity" (identity class), "grouping" (classification), and "container" (container class) defined by the target model (yang model).

[0091] When the definition data is the fourth data, the corresponding target data type is the module class, and the fourth data is the "module" (module class) defined by the target model (yang model).

[0092] The purpose of converting the definition data of the target model (yang model) to the corresponding target data type is to realize the mutual conversion between XML strings and data type instances, for example: XML string " <wtr> 300< / wtr> ", instantiate into a wtr object instance or convert a wtr object instance into an XML string" <wtr> 300< / wtr> ", for different target models (yang models), the implementation methods of mutual conversion are also different. The conversion of public classes, module classes, and enumeration classes is relatively simple, while the more complex one is the interface class. It is necessary to define the corresponding class definition according to each Interface (interface), and implement the relevant conversion logic between its XML string and data class instance. After these basic types of conversion are completed, more complex multi-layer XML nesting and combination will also be converted according to the conversion of the basic types, and finally complete the mutual conversion between XML objects and data class instances.

[0093] Due to the standardization of the target model (yang model) definition, it is relatively stable and widely applicable. Therefore, each yang module and object definition is universal and also suitable for other devices that use this yang module, thereby achieving the purpose of code reuse.

[0094] S5: Send an SDH service configuration prompt to the user interface according to the SDH service configuration result:

[0095] When the SDH service configuration result is successful, the SDH service configuration prompt sent to the user interface is that the SDH service is successfully configured; when the SDH service configuration result is failed, the SDH service configuration prompt sent to the user interface is that the SDH service configuration failed and the reason for the failure, so as to remind the user of the issues that need to be paid attention to when performing SDH service configuration again.

[0096] Before executing the SDH service configuration method, the user needs to log in to the NMS system. After the login is successful, the OTN device that needs to be configured for the SDH service is entered into the NMS system. Specifically, the device information of the OTN device is sent to the NMS system, and the OTN device is entered according to the device information so that the SDH service configuration of the OTN device is performed through the NMS server. Therefore, before executing the SDH service configuration method, it also includes sending a login interface to the user interface to enter the OTN device into the NMS system. After the user logs in successfully, that is, after the OTN device is successfully entered into the NMS system, the SDH service configuration interface, the SDH service scenario data interface and other interfaces for the OTN device to perform SDH service configuration are sent.

[0097] When configuring the SDH service of the OTN device through the NMS system, the NMS system interacts with the OTN device through the http transmission protocol and the netconf network configuration protocol. When calling the data template according to the SDH service model selected by the user, the data template is called based on the netconf network configuration protocol, so that different manufacturers and different devices can get the same result through XML data, which is convenient for the mixed SDH service configuration distribution of different manufacturers and different devices, thereby improving the efficiency of SDH service configuration distribution.

[0098] Next, the SDH service configuration method is further explained in combination with the specific implementation process, as follows:

[0099] See also Figure 6 As shown, firstly, an SDH service configuration interface is sent to the user interface, and service configuration data items such as service label, customer side data, and network side data are input on the SDH service configuration interface.

[0100] When the user inputs SDH service configuration data, the data items entered by the user are verified in real time. When the verification fails, the user is reminded to re-enter the data items displayed on the service scenario interface until the verification passes, and the user is allowed to submit the data.

[0101] After the user submits the data, the XML data template that needs to be assembled is determined according to the SDH service model selected by the user, and the XML data template and the SDH service configuration data entered by the user are called to automatically assemble into a target data message, and the target data message is sent to the OTN device. The OTN device feeds back a target result with the configuration result according to the target data message, determines the SDH service configuration result according to the target result, and sends the SDH service configuration result to the user interface to feed back the SDH configuration result (target result) to the user.

[0102] The present invention also provides a configuration system for SDH services of OTN equipment based on netconfig, which is applied to the above configuration method and includes:

[0103] Front-end modules for:

[0104] Display the SDH service configuration interface, SDH service scenario data interface, login interface and SDH service configuration prompts;
