Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a template processing method, apparatus, device, and computer readable storage medium.
Background
In NFV (Network Function Virtualization ) networks, network device functions are implemented by software, enabling flexible sharing of infrastructure resources. The basic service functions of the network elements are identical for the same type of network element provided by different manufacturers, whether physical network elements or virtual network elements, because the network function definitions followed by the network elements are identical. But from a software implementation point of view, the network elements of different vendors may differ.
When performing functional test on a network element of a specific class, the network element is generally deployed to an environment simulating the current network, and then is in butt joint with a peripheral network element to complete the functional test; or under the condition that the network elements are not in butt joint, the peripheral network elements are simulated through the instrument to perform functional test. If the same function test is to be performed by replacing the same kind of network elements of other manufacturers, the network elements of a new manufacturer are required to be imported, then the test topology is redesigned according to the imported network elements of the new manufacturer, and finally the deployment test is performed aiming at the redesigned test topology.
For the existing service system or test system, if the network element of a manufacturer a is replaced with the VNF (Virtualised Network Function, virtualized network function) of a manufacturer B to perform service online or test, the general steps include:
(1) VNF object loading: b, uploading the VNF packet of the manufacturer to an existing system;
(2) VNF template design: designing or updating the VNF template according to the uploaded VNF object;
(3) NS (Network Service) Network topology design: aiming at the VNF packet uploaded in the step (1), designing network topology or test topology of peripheral network elements to form network service;
(4) NS online deployment: and (3) carrying out instantiation deployment on the network service designed in the step (3).
However, in the existing network element testing flow, when the function test is performed on the same kind of network elements of different manufacturers, the NS network topology needs to be redesigned according to the VNF packets uploaded by different manufacturers. But in general the network topology is fixed for similar network elements, the same functional tests. Therefore, the test flow of the existing VNF network element is complicated.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart of a template processing method according to an embodiment of the present invention, as shown in fig. 1, including the following steps:
and 101, acquiring an abstract business template.
Wherein the abstract business template comprises an attribute of an abstract template resource, and the abstract template resource comprises an abstract VNF template.
In the embodiment of the invention, the abstract business template refers to a concrete template corresponding to a business, and the abstract business template is obtained by replacing some network elements in the concrete business template by the abstract template corresponding to the network element. The abstract template of the network element is obtained according to specific characteristics of a certain network element, connection relation between the network element and an external node, and the like.
The attribute of the abstract template resource may be an abstract resource list attribute, which is used to define the abstract template resource that needs to be replaced in the process of instantiating the service template.
Specifically, in this step, a specific service template of the target service may be obtained, and then, a network element corresponding to the VNF to be tested in the specific service template is replaced by a network element template PlaceHolder (PlaceHolder) corresponding to the VNF to be tested, to obtain a preprocessed specific service template. And finally, adding the attribute of the abstract template resource into the preprocessed concrete service template to obtain the abstract service template.
In order to flexibly replace or test the service network element, a specific service template corresponding to a certain service needs to be abstracted. The network elements in the abstract service templates may be placeholders of actual network elements, so as to represent that the network elements represented by the placeholders may be replaced and instantiated by the actual network elements. The abstract traffic templates may also be templates containing specific network elements and network element placeholders. The network connection in the abstract service template is the network connection between network elements abstracted according to the service characteristics. In practical application, the placeholder can be replaced by other identifiers, so long as the placeholder can represent the abstract service template, and a certain network element is replaced by the corresponding abstract template.
Optionally, before this step, the method may further comprise: and acquiring an abstract VNF template corresponding to the VNF to be tested according to the uploaded VNF packet. The abstract VNF template is obtained by using a connection relationship between the VNF to be tested and an external node.
Step 102, obtaining information of the target VNF.
The target VNF may be a VNF to be tested. In practical applications, the information of the target VNF may be obtained according to a selection of a user, including an attribute, an input parameter, and the like.
And 103, instantiating the abstract business template according to the information of the VNF and the abstract VNF template to obtain an instantiated business template.
Specifically, the information of the target VNF is filled into the abstract VNF template, so as to obtain an instantiated service template. That is, in this case, the information of the network element represented by the abstract VNF template, such as the attribute, the input parameter, etc., is replaced with the information of the target VNF.
In the above-mentioned instantiation process, to ensure the accuracy of the obtained service template, user input may also be obtained, and according to the input, the correspondence between the network of the target VNF and the target network in the abstract service template may be updated. The input may be an instruction or the like specifying a correspondence between the network of the target VNF and the network defined in the traffic template.
And generating an identifier for the instantiated service template for uniquely identifying the instantiated service template. Meanwhile, in order to instantiate the abstract template for a plurality of times, the attribute of the abstract template resource can be set to a preset value. Wherein the preset value may indicate that the attribute of the abstract template resource is null.
After instantiation, the instantiated business templates may also be distributed for subsequent operations.
In the embodiment of the invention, the abstract service template comprises the attribute of the abstract template resource, and the abstract template resource comprises the abstract VNF template, so that the service template does not need to be redesigned for each VNF in the process of instantiating the service template. Therefore, the scheme of the embodiment of the invention can simplify the test flow of the VNF network element.
In order to solve the problems in the prior art, the embodiment of the invention provides a topology template abstract method and a process for carrying out automatic test through abstract template instantiation, which can simplify the redesign process of NS when different manufacturers access network elements to network for test or function test, and simultaneously provides the concept of design state template instantiation.
Referring to fig. 2, fig. 2 is a flowchart of a test method according to an embodiment of the present invention. Fig. 3 is a schematic diagram of an implementation method of an embodiment of the present invention.
Referring to fig. 2 and 3, the testing method according to the embodiment of the present invention may include the following steps:
step 201, obtaining a VNF package.
When a certain VNF network element needs to be tested, a VNF packet of the VNF network element to be tested needs to be uploaded. As shown in fig. 3, both manufacturer a and manufacturer B have VNF network elements for testing, so VNF packages uploaded by manufacturer a and manufacturer B may be obtained respectively.
Step 202, obtaining a VNF abstract template.
To design an abstract NS, an abstract VNF template needs to be defined first. With reference to fig. 3, the process includes: VNF composition definitions and VNF attribute settings. An abstract VNF template refers to a VNF template defined based on characteristics of the network element under test that can be replaced by a real network element under test. Assuming that the network element under test is a PCRF (Policy and Charging Rule Function, policy and charging rules function), the abstract PCRF template needs to be designed to extract external connection points of the PCRF with the HSS (Home Subscriber Server ), SCSCF (Service Call Session Control Function, serving call session control function) and corresponding network part features.
Step 203, obtaining an abstract business template.
And designing an abstract business template according to the obtained abstract VNF template. The concrete steps of abstract business template design include:
(1) The network topology is abstracted.
The network topology is certain for traffic consisting of specific network elements. Thus, the network topology may be abstracted. When abstracting the test topology of a specific network element, the network topology of the general service of the network element is to be combined for abstracting, and the network connection between the replaced network element and the network element is mainly abstracted.
Taking fig. 4 as an example, fig. 4 is a topology example of a VoLTE (Voice over Long-Term Evolution) service composed of various network elements.
For flexible replacement or testing of service network elements, the above-mentioned service templates need to be abstracted. Network elements in the abstract service template can be placeholders of actual network elements and can be replaced and instantiated by the actual network elements; the network element in the abstract service template may also be a template comprising specific network elements and network element placeholders. The network connection in the abstract service template is a network connection between network elements abstracted according to the service characteristics.
Assuming that CSCF (Call Session Control Function ) and TAS (Telephony Application Server, telephony application server) are network elements to be replaced or as test objects, an abstract network topology is shown in fig. 5.
In fig. 5, CSCF PlaceHolder is a CSCF network element template PlaceHolder and TAS PlaceHolder is a TAS network element PlaceHolder. When a real CSCF or TAS network element accesses the tested system for testing, the CSCF PlaceHolder and the TAS PlaceHolder are instantiated and replaced by the real tested CSCF or TAS. In fig. 5, CSCF and TAS PlaceHolder are abstract VNF templates designed according to step 202.
According to fig. 5, an abstract traffic template example is shown in fig. 6. In fig. 6, control-net and Data-net are network connections between the real network elements that are abstracted, which requires business personnel to abstract according to experience.
(2) Extending a description of the abstract template resource.
During testing, the corresponding VNF abstract template in the abstract service template is replaced by the VNF of a real manufacturer, and then the running state deployment or testing can be performed. In order to define or identify such traffic templates that need to be instantiated and to accurately identify which VNFs in the traffic templates are abstract VNFs, i.e. placeholders VNFs that need to be replaced by real VNFs, in an embodiment of the present invention, abstract resource list attributes are added to the abstract traffic templates for defining abstract template resources that need to be replaced.
The fields and meanings included in the abstract resource list attribute are shown in table 1:
TABLE 1
Wherein, attribute represents Attribute name, attribute is used for identifying whether the Attribute is optional or necessary, and carry represents the length of the value of Attribute, takes values of 0 to N, N is an integer greater than 0, content is Content, VNFD, description is Attribute Description.
When the abstract business template does not have the attribute, the abstract business template can be considered as a directly deployable template without an instantiation process.
Step 204, instantiating an abstract business template.
As shown in fig. 7, the process of instantiating the abstract business template may include:
step 701, analyzing the abstract business template to be instantiated, and determining whether the business template to be instantiated is the abstract business template. If the business template to be instantiated contains abstract resource list attributes, the template to be instantiated is an abstract business template, and the abstract business template is required to be instantiated into a concrete template and then distributed; if the template to be instantiated does not contain the abstract resource list, the template to be instantiated can be directly distributed to a running state for deployment.
In the embodiment of the invention, a processing procedure of the business template to be instantiated as an abstract business template is described in an important way. The specific process comprises the following steps:
step 702, obtaining a VNF abstract resource list corresponding to the placeholder resource attribute. In this process, the user may choose to upload the VNF abstract resources that the real VNF corresponds to replacing. Accordingly, information of the real VNF selected by the user may be acquired.
In step 703, the information of the real VNF is analyzed, and the basic information, such as the attribute, of the corresponding abstract VNF in the abstract service template is replaced with the information of the real VNF, so as to input parameters. In addition, the user may specify a correspondence between the network of the real VNF and the network defined in the abstract traffic template. Correspondingly, according to the specification of the user, the connection relation between the network of the real VNF and the network defined in the abstract service template can be adjusted.
Through the above process, the process of instantiating the abstract business template is completed.
Step 704, for the instantiated business template, a template id (identification) may be generated for uniquely identifying the template. Meanwhile, the placeholder resource attribute of the service template can be set to be empty. In this way, it may be ensured that the original abstract VNF template in the abstract traffic template does not change, thereby allowing multiple instantiations of the abstract traffic template.
Step 205, distributing the instantiated abstract business templates.
In this step, the instantiated abstract business templates are distributed to the run-state deployment.
In the embodiment of the invention, the process of service design in the process of service deployment or test of the same network element function of different manufacturers can be simplified through abstract VNF design and abstract service topology templates, and the method and the device are applicable to different fields. Meanwhile, aiming at the service template after instantiation, the real VNF object and the instantiation template can be bound, so that the original design flow can be simplified, and the service deployment flow can be more automatic.
