In order to make those skilled in the art more fully understand the present invention, with reference to the accompanying drawings and detailed description to this hair
It is bright to be described in further detail.
Note: the example next to be introduced is only a specific example, and not as limiting embodiments of the invention
It is necessary for following specific step, numerical value, condition, data, sequence etc..Those skilled in the art can be by reading this explanation
Book constructs the more embodiments that do not mention in this specification to use design of the invention.
Shown in Figure 2, SDN controller includes northbound interface, YANG parsing module, YAML turns XML module, south orientation connects
Mouthful.
Northbound interface provides calling interface for control program, realizes that YANG pattern query, YANG model configuration information issue
Etc. functions.
YANG parsing module completes YANG file and reads, the correctness of verification YANG file dependence, parses YANG language
Method, the model for generating YAML format describe file.
Why YANG file will be parsed into YAML file, be because the data of YAML format are more friendly to user, more
It is easily processed, advantageously when carrying out data interaction, control program interface building.YAML format be it is a kind of intuitively can be by
The Data Serialization format that computer identifies is a readability height and is easy to be read by the mankind, easy to be interactive with scripting language,
For expressing the programming language of data sequences.It is analogous to the data description language of the subset X ML of standard generalized markup language,
Grammer ratio XML is simple very much.
After SDN controller receives the configuration information for the YAML format that control program is sent, YAML turns XML module for YAML lattice
The configuration information of formula switchs to XML format, and is issued in equipment by the channel NETCONF in southbound interface.
Controlling program is user application (APP), and gui interface is presented.In embodiments of the present invention, the master of program is controlled
Function is wanted to have:
1. calling northbound interface interrogation model description information；
2. the model description information of YAML format is parsed according to default rule, it is automatic to construct YANG model configuration interface,
The hierarchical relationship of YANG data is shown with tree, the node in tree supports editting function.
3. the data constraint rule defined according to YAML model, verifies the data of user's input, such as: effective model
Enclose, default value, character length, canonical matching etc..
Shown in Figure 3, the process flow of YANG parsing module is as follows:
SDN controller reads YANG file, verifies the correctness of YANG file machine dependence；Parse YANG file language
Method extracts model information；It is the model description information of YAML format by YANG model conversion.
The verification principle of YANG file and dependence is as follows:
1. file format is YANG type；
2. whether the file relied on exists；
3. whether correct fileversion number is, if consistent；
4. whether producing Circular dependency between file.
When YANG parsing module is by the model description information that YANG model conversion is YAML format, needs to formulate and reflect accordingly
Penetrate rule.
YANG model and the mapping ruler of the model description information of YAML format are as shown in table 1, the formulation of the mapping ruler
Principle is the mould of the intension consistency based on YANG model node and YAML node, i.e. YANG model node and YAML node description
Type object is meant that the same, and the YANG model node equity with identical meanings is converted to YAML node.
The mapping ruler of table 1, YANG model node and YAML node
Wherein, the Chinese of YANG node is explained as follows:
Container: container node；
List: list node；
Leaf: leaf node.
The Chinese of YAML node is explained as follows:
Object: Object node；
Array: array node；
Int8:8 integer nodes；
Int16:16 integer nodes；
Int32:32 integer nodes；
Int64:64 integer nodes；
Decimal64:64 decimal number nodes；
String: character string type node；
Enumeration: enumeration type node；
Bool: Boolean type node.
In YANG file, container, that is, container node, for summing up relevant node to a subtree
In subtree, container node only has child node, void value.Container may include any quantity, any kind of
Child node, including leaf node leaf, list node list, container node container.
List is list node, defines a series of list items.All list items are all mutually isostructural examples, this is
The important difference of list node and container node.One list node can include any amount, any type of sub- section
Point, including leaf node leaf, list node list, container node container.
Leaf is leaf node, contains the fundamental type data as integer or string.It has and only has
One certain types of value, and there is no child node.
In table 1 mapping ruler the specific implementation process is as follows:
YANG parsing module reads YANG file, by the way of recursive traversal, identifies the keyword in YANG file；
Container node is encountered, is the object node in YAML file by the Node；
List node is encountered, is the array node in YAML file by the Node；
Leaf node is encountered, the data type of the leaf node is further parsed.
YANG model onboard data type generally has: int8, int16, int32, int64, decimal64, string,
Enumeration, boolean, these data types be eventually mapped to int8, int16 in YAML file, int32,
int64、decimal64、string、bool、enumeration。
In addition, YANG is able to use " typedef " statement defines derived type from fundamental type.It is used in YANG
The customization type of " typedef " statement, is derived from fundamental type data due to being, so when switching to the type in YAML,
Mapping ruler is consistent with fundamental type data.YANG parsing module is based on above-mentioned mapping ruler, the model information that YANG is defined,
At the model description information of YAML format, the information such as data type, data constraint rule completely retain for complete escape, are not in
Semanteme missing.
The northbound interface of SDN controller be control routine access controller inlet module, mainly provide pattern query,
YANG model configuration information such as issues at the functions.
Shown in Figure 4, the process of the northbound interface interrogation model of SDN controller is as follows:
When the northbound interface of SDN controller receives the interrogation model request from control program, according to querying condition, positioning
To specific YAML file；
SDN controller reads YAML file content, is packaged into http protocol format；
The northbound interface of SDN controller returns data to control program.
Shown in Figure 5, control program parses the model description information of YAML format according to default rule, automatic to construct
The process of YANG configuration interface is as follows:
Program is controlled in a manner of http request, initiates interrogation model request to SDN controller, control program passes through calling
The northbound interface interrogation model description information of SDN controller；
Control program gets the model description information of SDN controller return being defined with YAML format；
Program is controlled according to default rule analytic modell analytical model description information, and constructs YANG model configuration interface automatically.
Since interface constructs automatically, completely without manual intervention and overlapping development, greatly save manpower and when
Between put into.
YANG model configuration interface shows the hierarchical relationship of YANG data with tree, and the node in tree is supported
Editting function completes the increasing of YANG model, deletes, changes, Cha Gongneng.
In addition, carrying data check rule in YAML model description information, these rules in a control program also can be by
Expressed intact needs to verify validity, the legitimacy of data when user is when inputting YANG configuration information.
The interface element for controlling program is generated based on YAML, it then follows GUI (the Graphical User in table 2
Interface, graphic user interface) create-rule.
Table 2, GUI create-rule
GUI create-rule in table 2 defines YANG model to the mapping ruler at interface, and the essence of the mapping ruler is base
In YANG model node, YAML node, control program Basic Elements of Graphic User Interface descriptive model ability to express on consistency, will have
There is the node of identical intension to carry out reciprocity conversion, YANG model is allow to translate into YAML, control program figure circle by lossless
Face.
The mapping ruler at YANG model to interface is the core rule that the embodiment of the present invention can be realized that interface constructs automatically,
It is the switching foundation that Model Abstractionization is embodied to graphic user interface.GUI create-rule of the program based on table 2 is controlled, is passed through
The back end for parsing YAML, generates corresponding GUI element, and what is be presented to the user is exactly the tree-shaped of the nesting that can be unfolded
Structure.
Control program interface generating process the following steps are included:
1. controlling the tree-shaped node of Program Generating if it is object node, which can be unfolded, can wrap after expansion
Node containing any type, such as: object, array, basic data type；
2. controlling the tree-shaped node of Program Generating, which can be unfolded, and support additions and deletions sub- section if it is array node
Point, all child nodes have same data structure, and child node can be object or fundamental type data；
3. if it is leaf node, i.e. fundamental type data cannot be further spread out, leaf node can be edited.
According to different fundamental type data, control Program Generating and have the control of user's editting function such as: text box, radio box, under
Draw frame etc.；
4. data check rule is not visual interface element, be included in said modules as hiding attribute, to
The data of family input are verified.
Shown in Figure 6, the process that control program issues YANG configuration information is as follows:
User needs to fill in configuration information in YANG configuration interface；
Data are verified, during filling in, and before issuing configuration, control program requires the conjunction to data
Method is verified, and verification rule of the verification rule in YANG file, this verification rule is in YANG model analyzing
Stage is by the lossless data check rule be converted in YAML file；
After data check is errorless, program is controlled by YANG configuration information and is assembled into YAML format, to the north of SDN controller
Http request is sent to interface, calls the YANG configuration information of SDN controller to issue interface, configuration information is issued.
Shown in Figure 7, the process that SDN controller issues YANG configuration information is as follows:
The northbound interface of SDN controller, which is received, issues YANG model request from control program；
The YAML of SDN controller turns XML module and converts equipment for the configuration information of the YAML format received can to identify
XML format；
