Workflow implementation method and device

Abstract

The invention provides a workflow implementation method and a device, and belongs to the field of ONAP service models. The workflow implementation method is applied to an instantiation template of anend-to-end service. The instantiation template allows a plurality of resource instances to be dynamically instantiated as required; the simple service is a resource of the composite service; resourceinstances in the composite service instantiation data record are stored in a list structure; wherein the instantiation template comprises a maximum resource quantity parameter and describes the upperlimit quantity of resources needing to be instantiated in the composite service, and the upper limit quantity comprises the steps of dynamically increasing the quantity of the resources of the instantiation template and judging whether the quantity of the resources can be dynamically increased according to the quantity limit of the maximum resource quantity parameter. By means of the method, onlyone unified template needs to be designed for complex services, multiple service templates do not need to be designed, the solidification limitation of the service templates on the number of resourcesis changed, the flexibility is enhanced, and workflow for guiding the service arrangement module to dynamically update the services is increased.

Description

technical field [0001] The present invention relates to the business model field of ONAP, in particular to a workflow realization method and device. Background technique [0002] ONAP (Open Network Automation Platform, Open Network Automation Platform), as the brain of NFV (Network Function Virtualization, Network Function Virtualization) / SDN (Software Defined Network, Software Defined Network), through service design, service orchestration, service online, strategy operation The four links realize the automatic management of the entire life cycle of the network, and are the core components of the new generation of network management. Among them, the service design is completed in the running state. In the SDC (Service Design and Create, business design module, ONAP design state module) link, the resource template of the third-party manufacturer is launched online, and the corresponding network element is selected by dragging and dropping. , to complete the assembly of the ...

AI Technical Summary

Problems solved by technology

[0003] The current business model of ONAP is designed based on the existing capabilities of the business design module. It only has two types of business (service) and resource (resource). It can only assemble simple business templates and does not have the design capabilities of complex business templates. For a composite Business (composite service), need to design a combination of multiple business templates, which cannot be realized in a unified business template

Moreover, the existing template only describes the number of resources and topology structure required for business instantiation, the number is fixed, and does not support dynamic adjustment of business

Furthermore, the existing workflow does not dynamically update the workflow of the business, and cannot guide the business orchestration module to dynamically update the business

This largely limits the build and assembly of end to end service
