Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention more apparent, the following detailed description will be given with reference to the accompanying drawings and the specific embodiments.
ONAP (Open Network Automation Platform ) is used as the brain of NFV (Network Function Virtualization, network function virtualization)/SDN (Software Defined Network ), and the four links of service design, service arrangement, service online and strategy operation are used for realizing the automatic management of the whole life cycle of the network, thus being a core component of a new-generation network management. The service design is completed in an operation state, and in an SDC (Service Design and Create, service design module, ONAP design state module) link, a resource template of a third party manufacturer is online, and the network service model is assembled by selecting corresponding network elements and adopting a dragging mode. The service orchestration analyzes the service template through SO (Service Orchestration, service orchestration module, ONAP's service orchestration module) and disassembles it into multiple tasks to form a workflow. When the service is on line, service configuration is carried out according to the service requirement, and the current network user data is loaded to finish the service on line. When the strategy is operated, based on the strategy and combining with the network state, the functions of network elastic expansion and contraction, network element iteration and the like are automatically realized, and closed-loop control is realized.
The current business model of ONAP is based on the existing capability design of a business design module, only has two types of business (service) and resource (resource), only can assemble a simple business template, and does not have the design capability of a complex business template, so that the construction and assembly of an end-to-end business (end to end service) are limited to a great extent. At present, communities have proposed compound services (composite service), and after composite service is introduced, complex services can be designed so as to present a unified end-to-end service to users, but at present communities do not have designs and schemes based on composite service templates and implementations.
The service template currently generated by the service design module can only be used for guiding service instantiation, and has great limitation when the service life cycle is arranged, especially when dynamic adjustment is involved, because the template is solidified for the quantity of resources and the topology description of the service. Meanwhile, the existing business template attribute and function described by the business design module AID (the business design module TOSCA Data Model ) document are too few, the business template cannot be dynamically updated in the running state, the internal running state component cannot dynamically adjust the business by referring to the existing business template, and the existing workflow also cannot support the function of dynamically adjusting the business.
Currently, there is no unified information model of a service template, and only service data models implemented based on TOSCA (Topology and Orchestration Specification for Cloud Applications, topology and orchestration specifications of cloud applications) are described in AID documents proposed by a service design module team. Similar to the ONAP traffic template information model, is an information model of an ETSI (European Telecommunications Standards Institute, european telecommunications standardization institute) designed web service (NS) template. NS is defined in ONAP as a concept at the resource level, differing from the concept of service in ONAP mainly in the following two aspects: on the one hand, the management of the lifecycle of NS is operated by VFC (Virtual Function Controller, virtual function management module of ONAP) or APPC (Application Controller, APP management module of ONAP) instead of the service orchestration module, which is responsible for managing the lifecycle of the service; on the other hand, service is an object oriented client, and Service contains some attributes such as SLA (Service Level Agreement) describing the client's needs.
Taking the cross-domain cross-layer VPN use case (Cross Domain and Cross Layer VPN, CCVPN) as an example, the use case is mainly directed to government and enterprise customers. Assuming that a certain enterprise currently constructs a VPN service from Beijing to Shanghai, along with the expansion of the operation scale of the enterprise, the enterprise now wants to add a western security site on the basis of the original service. The existing service model design mode can realize the service scenario, but is based on a plurality of services, and the user faces the plurality of services. The design simply realizes the construction of VPN private line, and greatly violates the original purpose that a user wants to provide a unified end-to-end service.
1. Existing business model design
The services of the ONAP are all template driven, and one type of service needs to be instantiated according to the service template designed by the service design module. Different services need to refer to different service templates. Taking the CCVPN service shown in fig. 1 as an example, an enterprise wants to establish a VPN service from site a to site B, and needs to implement by establishing three services: setting up a site a service, a site B service, and an intermediate VPN connection VPN Infra Service are also required. These three services are implemented with reference to 2 different service templates (service templates), site and VPN Infra (VPN architecture) service templates.
In the existing template design, the template only supports service instantiation, and does not support service change related to resource configuration initiated by a user. For user initiated service changes, it is necessary for the user to enter resource configuration parameters instead of relying on the ONAP to automatically perform configuration of newly added resources, such as scaling-up and self-healing. The following diagram describes a service template described in TOSCA language, where the service template is a yml file in the csar file of a service, as shown in fig. 2, and is used to guide the instantiation of the service in a running state, where the service template is: metadata is used to describe specific attributes of the service, such as UUID (Universally Unique Identifier, universal unique identifier), serviceType, category, etc.; inputs are used to describe attribute information that requires user input when instantiating a service; node_template describes the resources required for the service; workflow describes the workflow required for service execution.
In both metadata of the service template and node_template describing the resources, the number of resources to be instantiated is fixed, and the instantiation order of the resources is determined by the description order in the template. In the service execution process, if the user generates demand adjustment on the service, such as demand change on the resource quantity, the original service needs to be terminated first, the template meeting the resource quantity demand is redesigned, and then a new service is instantiated according to the template.
Because the existing template only supports the business instantiation work, only the business workflow is created, and the business workflow is not updated.
The disadvantages of the prior art are mainly manifested in the following three points: 1. for a composite service (composite service), multiple service templates need to be designed to be combined and implemented, and cannot be implemented in a unified service template. 2. Only the quantity and topology structure of resources required by service instantiation are described in the existing template, the quantity is solidified, and the dynamic adjustment of the service is not supported. 3. The existing workflow does not have a workflow for dynamically updating the service, and the service arrangement module cannot be guided to dynamically update the service.
1. Problems with existing models:
the existing implementation mode of the composite service can only be assembled into a simple service by resources, and then the simple service is combined into the composite service, so that the design and the implementation of the composite service can not be directly carried out. Taking CCVPN traffic as an example, the main drawbacks include: current business designs present both sites and VPN connections as business to users, respectively. To build a SOTN (Software-defined Optical) from enterprise to enterprise
Transportation Network, software defined optical transport network) service is exemplified: in the design of the current service model, in order to open a vpn service, a user needs to establish three services forming the service in a portal interface: SOTN VPN INFRA1, CPE SITE1, CPE SITE 2; when a user wants to add a site again, three services need to be recreated: CPE SITE3, SOTN VPN INFRA2 from SITE1 to SITE3, SOTN VPN INFRA3 from SITE 2 to SITE 3. An essential disadvantage of splitting a service into multiple service implementations for the same customer-aware service is that for the inside of the ONAP system the biggest penalty is that it will consider these three services to be uncorrelated, requiring an external service system to correlate them. Dynamic flexible closed loop control at the traffic level cannot be implemented inside the ONAP for these services.
2. The existing business templates have the following problems:
only the instantiation of the service is supported in the current service template, and the dynamic adjustment of the service is not supported. The number of resources required in the service is also limited in a solid state, and only instantiation of a single resource is supported. These drawbacks make dynamic adjustment of the traffic impossible to refer to the traffic templates.
3. The existing workflow does not have a workflow for dynamically updating the service, and the service arrangement module cannot be guided to dynamically update the service.
In order to solve the above problems, embodiments of the present invention provide a workflow implementation method and apparatus, which only needs to design a unified template for complex services, and does not need to design multiple service templates, thereby changing the curing limit of the service templates on the number of resources, enhancing flexibility, and increasing a workflow for guiding a service orchestration module to dynamically update services.
Embodiments of the present invention provide an instantiation template of an end-to-end service that allows multiple resource instances to be dynamically instantiated on demand.
Further, in the instantiation template, the simple service is a resource of the compound service, and the resource instance in the compound service instantiation data record is designated to be stored in a list structure.
Further, the instantiation template includes a maximum number of resources parameter describing an upper limit number of resources to be instantiated throughout the lifecycle of the composite service.
In this embodiment, the curing limit of the service template on the number of resources is changed, so that flexibility is enhanced, and the concrete steps are as follows: on the one hand, adding attributes in the template: a maximum resource number parameter for describing an upper limit number of resources to be instantiated in the whole life cycle of the composite service; on the other hand, the realization mode of the resources in the template is changed, a list structure is introduced, the resource examples in the compound service instantiation data record are stored in the list structure, and the user can dynamically increase the resources.
Taking CCVPN traffic as an example, site and VPN Infra are stored in node_template, and implementation of site and VPN Infra is instantiated with reference to vnfd.
Fig. 3 shows an information model of service descriptor (service description), and in composite service descriptor (composite service description), in order to describe the upper limit number of each resource required by the composite service, a maxNodeNum attribute (i.e., a maximum resource number parameter) is added. Thus, each atom service can be used as a resource of composite service (composite service), and a template can be used for describing composite services composed of a plurality of simple services. Fig. 4 shows that an attribute of a list structure needs to be added to metadata of an extended template, service template (i.e., an end-to-end Service instantiation template in an embodiment of the present invention): the paddingFlavor is used to describe the upper bound number of resources that need to be instantiated throughout the life cycle of a service. maxNodeNum in the information model is the corresponding service template in the paddingFlavor.
The resources in node_template are originally vf, vl, cp, ar, instead of vf_list, vl_list, cp_list, ar_list. The list structures are used for guiding the instantiation of the resources in the whole life cycle of the service, the service can dynamically increase the number of the resources when dynamically updating, and whether the number of the resources can be dynamically increased is judged according to the limit of the number of the paddingFlavor.
The embodiment of the invention also provides a workflow realization method, which is applied to the instantiation template of the end-to-end service, wherein the instantiation template allows a plurality of resource instances to be dynamically instantiated according to the requirement, in the instantiation template, simple service is the resource of compound service, the resource instances in the compound service instantiation data record are stored in a list structure, the instantiation template comprises a maximum resource quantity parameter and is used for describing the upper limit quantity of the resource required to be instantiated in the whole life cycle of the compound service, as shown in fig. 5, the method comprises the following steps:
step 101: and dynamically increasing the number of resources of the instantiation template, storing the resource instances in the compound service instantiation data record in a list structure, and judging whether the number of resources can be dynamically increased according to the number limit of the maximum resource number parameter.
In this embodiment, the curing limit of the service template on the number of resources is changed, so that flexibility is enhanced, and the concrete steps are as follows: on the one hand, adding attributes in the template: a maximum resource number parameter for describing an upper limit number of resources to be instantiated in the whole life cycle of the composite service; on the other hand, the realization mode of the resources in the template is changed, a list structure is introduced, the resource examples in the compound service instantiation data record are stored in the list structure, and the user can dynamically increase the resources; in yet another aspect, the operational state regulation capability is enhanced, and a workflow for guiding the service orchestration module to dynamically update the service is increased. Compared with the existing complex service implementation mode, the embodiment only needs to design a unified template, a plurality of service templates are not needed to be designed, the templates can be used for guiding dynamic updating of the service, and resources of the service can be dynamically increased.
Further, the present embodiment provides a method for guiding a service orchestration module to update a service and dynamically increasing a workflow of a resource, as shown in fig. 6, where the method specifically includes:
the user interaction module of the ONAP receives an ADD resource request (ADD);
the user interaction module sends the resource increasing request to a business arrangement module of an ONAP, and judges whether the business arrangement module supports the resource increasing request or not;
