Example one
An embodiment of the present invention provides a deployment method for describing VNFD multi-deployment specifications by a virtualized network function, as shown in fig. 1, where the method includes:
s101, determining a VNFD multi-deployment specification required by a network element or cloud application;
s102, describing each deployment specification in a mapping child node of the topology _ template (cloud application topology orchestration specification template) of the network element or the cloud application.
The embodiment of the invention describes each deployment specification in the mapping sub-node of the cloud application topology arrangement specification template of the network element or the cloud application by determining the VNFD multi-deployment specification required by the network element or the cloud application, thereby being used for any scene using TOSCA to describe the network element multi-deployment specification and further achieving the effect of self-selecting the deployment specification by a user to deploy the network element.
The embodiment of the invention is mainly executed at a network element side or a cloud application side.
On the basis of the above embodiment, a modification of the above embodiment is further proposed.
In this embodiment of the present invention, optionally, before describing each deployment specification in the mapping child node of the cloud application topology orchestration specification template of the network element or the cloud application, the method includes:
adding a plurality of mapping child nodes in a subsystem _ mapping node of the cloud application topology orchestration specification template;
a deployment specification is defined in each mapping child node.
In detail, the definition of TOSCA supports referencing between templates. The TOSCA template defines a sub _ mappings key for the support reference, exposing the TOSCA template as a node for other template references. The requirements of the application described by the template on the outside and the capability provided by the application, such as connection points for the application to communicate with the outside and the requirement on an external network, are defined in the support _ maps. However, in the existing standard, the subsystem _ mapping only defines a set of information for partial requirements, and the VNFD describes multiple deployment specifications, different deployment specifications have different external connection points and external network requirements, so the TOSCA cannot support such an application scenario, but in the embodiment of the present invention, multiple mapping sub-nodes are added in the substitute mapping node of the cloud application topology orchestration specification template, and one deployment specification is defined in each mapping sub-node, so that the TOSCA template can support multiple deployment specifications.
Wherein, defining a deployment specification in each mapping child node optionally comprises:
defining a node type parameter and properties parameter in each mapping child node;
defining mapping _ name (deployment specification name) parameter and deployment _ members (deployment node list required by deployment specification) parameter in the attribute parameters.
In this embodiment of the present invention, optionally, the defining a deployment specification in each mapping child node further includes:
requirements and capabilities parameters are defined in each mapping child node.
Wherein, the describing each deployment specification in the mapping child node of the cloud application topology orchestration specification template of the network element or the cloud application optionally includes: for each mapping child node:
in the deployment specification name parameter, the deployment node list parameter, the requirement parameter and the capability parameter of the mapping child node, the deployment specification name, the deployment node list required by the deployment specification, the external connection point provided by the deployment specification to the outside and the requirement of the deployment specification to the external network are respectively described.
In this embodiment of the present invention, optionally, before describing each deployment specification in the mapping child node of the cloud application topology orchestration specification template of the network element or the cloud application, the method includes:
defining a default _ reflector (multi-deployment rule support) parameter for supporting a user to select a deployment specification in input parameters of the cloud application topology deployment specification template.
In this embodiment of the present invention, optionally, the method further includes:
defining default parameters and constraints parameters in the multi-deployment rule support parameters; a type parameter may also be defined.
The default parameters are used for describing deployment specifications selected by a user in a default mode; the constraint parameters are used to describe user selectable deployment specifications.
In this embodiment of the present invention, optionally, after the describing each deployment specification in the mapping child node of the cloud application topology orchestration specification template of the network element or the cloud application, the method includes:
adding deployment nodes required to be used by each deployment specification into node templates of the cloud application topology deployment specification template; where the deployment node may be a member of the deployment, such as a virtual machine.
In this embodiment of the present invention, optionally, after adding, to the node template of the cloud application topology orchestration specification template, a deployment node that needs to be used in each deployment specification, the method includes:
in relation templates of the cloud application topology orchestration specification template, capability and requirement management relations existing between the deployment nodes are described.
In detail, the improvement points of the embodiment of the invention relative to the existing TOSCA template comprise:
and adding a fixed parameter, deploy _ viewer, in the input parameter part, thereby supporting the user to select the deployment specification.
Under the subsystem _ mapping node, a mapping child node is added, and there may be multiple mapping child nodes, each defining a deployment specification.
The externally provided external connection point of the deployment specification of the VNFD is described in mapping capabilities parameter, and the requirement of the deployment specification of the VNFD on an external network is described in requirements parameter.
The mapping _ name attribute is added to properties to distinguish different deployment specifications. The added deployment _ members attribute is to illustrate the members (including nodes, relationships, groups, policies, and the like) of the deployment required by the deployment specification, and different members of the deployment are required by different deployment specifications.
Through the improvement points, the embodiment of the invention can be used in any scene using TOSCA to describe the multi-deployment specification of the network element, and achieves the effect of self-selecting the deployment specification by a user to deploy the network element.
The following embodiments of the present invention are described with reference to a practical application scenario.
In the implementation process of the embodiment of the invention, the method can comprise the following steps:
step 1, the network element fills a VNFD template of the network element according to the TOSCA specification.
And 2, if a plurality of deployment specifications exist, describing different deployment specifications in different mapping by the network element.
And 3, adding all deployment nodes required to be used by the deployment specification into the node _ templates by the network element.
And 4, if the capabilities-requirement management such as dependency relationship, reference relationship and the like exist among the nodes, describing the network element in relationship _ templates.
And 5, if the template has input and output parameters, the network element fills in the input parameters and the output parameters. The input parameters of the deployment specification are required in the inputs parameter section.
And 6, when a Network element is deployed by a VNFM (virtual Network Function Manager), analyzing a TOSCA (transmitter optical transport architecture) template of the VNFD, and deploying according to a deployment specification selected by a user.
For example, an EM network element supporting multiple specifications is designed, the EM network element supports selection of deployment specifications according to a required scenario, that is, a low _ availability scenario and a high _ availability scenario are supported, and a user can select deployment according to a scenario requirement.
The TOSCA template supports two deployment modes of the EM network element, namely only one virtual machine can be deployed in a low-reliability demand scene, and the main virtual machine and the standby virtual machine are deployed in a high-reliability demand scene.
And when the VNFM analyzes the TOSCA template information of the EM network element, determining the deployment specification according to the selection of the deployment specification input by the user. If the user inputs low _ availability in the input parameter default _ policies, the VNFM deploys a virtual machine to expose the network requirement of a port. If the user inputs high _ availability in the input parameter default _ browsers, and VNFM deploys the active virtual machine and the standby virtual machine, the network requirements of the two ports are exposed to the outside.
Thus, the TOSCA template file for an EM network element is defined as follows:
in the embodiment of the invention, the description of multiple deployment specifications of one VNF or application can be supported in one TOSCA template, and the use of one TOSCA template in multiple requirement scenes is supported, so that the requirement of the ETSI NFV-IFA011 specification on the description of the multiple deployment specifications is met, and the requirement of the multiple deployment specifications in other specifications or practical application can also be met.
