VNF Deployment Automation via Flavor Parameter Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In network function virtualization (NFV), the manual input of input parameters for secondary files during virtualized network function (VNF) deployment is labor-intensive and prone to errors, leading to high human interference and performance issues due to the need for programmers to understand and manage different deployment flavors and their corresponding parameters.
Innovation Solution
A method where a virtualized network function manager (VNFM) uses a mapping relationship between primary and secondary files to automatically determine deployment parameters based on flavor parameters, reducing programmer intervention and improving automation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input of input parameters is used for secondary files during VNF deployment, then programmers can control the deployment process, but labor costs increase and human interference is high
Solution Approach 1:
The system enables self-service by allowing the deployment system to automatically retrieve and fill input parameters for secondary files using the mapping relationships and flavor parameter values, eliminating the need for manual programmer intervention in parameter input
Solution Approach 2:
The mapping relationships between primary and secondary files serve as an intermediary mechanism that automatically translates flavor parameter values into the appropriate input parameters for secondary files, reducing direct human interference in the deployment process
2Reliability
If programmers manually input parameters for different deployment flavors, then deployment flexibility is maintained, but errors increase and performance decreases
Solution Approach 1:
The system implements feedback by automatically verifying and filling parameters based on the mapping relationships and flavor parameter values, reducing human errors and improving deployment reliability
Solution Approach 2:
The mapping relationships between primary and secondary files are pre-configured to establish the correct parameter associations, allowing the system to automatically determine the appropriate input parameters without manual intervention during deployment
3Device complexity
If manual parameter input is required, then programmers can understand deployment flavors, but the complexity of the deployment process increases
Solution Approach 1:
The mapping relationships act as an intermediary that automatically handles the complex parameter translation between primary and secondary files based on flavor parameters, reducing the perceived complexity for programmers
Solution Approach 2:
The deployment process is segmented into distinct components: primary file processing, mapping relationship management, and secondary file deployment, allowing automated handling of each segment and reducing overall process complexity

AI summary
In a method of deploying a virtualised network function (VNF), a virtual network function manager (VNFM) obtains a virtualized network function descriptor (VNFD) that includes a primary file and one or more secondary files that have a mapping relationship with the primary file. The primary file includes a deployment parameter of each secondary file, and a association relationship indicating that a value of a flavour parameter of the VNF is associated with the deployment parameter of the secondary file. The VNFM then determines a target file from the one or more secondary files based on the value of the flavour parameter of the VNF and deploy S the VNF based on the association relationship and a mapping relationship between the primary file and the target file.
