VNF Hosting Evaluation Using Pre-Deployment Compatibility Tests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VNF deployment techniques in telecommunications networks face scalability issues due to outdated infrastructure capacity information, leading to inefficient and unreliable placement of virtualized functions, especially in distributed data centers, which fail to meet low latency requirements and result in suboptimal quality of service.
Innovation Solution
A method for determining a hosting device by sending compatibility tests to verify resource suitability, including assessing computing and storage capacity, and latency requirements, ensuring the hosting device meets the virtualized function's needs through up-to-date testing before installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ILP optimization techniques are used for VNF placement, then placement accuracy is improved, but processing time increases significantly
Solution Approach 1:
The patent performs capacity verification tests on hosting devices before VNF placement decisions are made. The management entity sends test requests to virtualization entities to pre-validate infrastructure capacity, so that when placement decisions are needed, the information is already available and up-to-date, avoiding time-consuming processing during actual placement operations.
Solution Approach 2:
The virtualization entity autonomously executes capacity verification tests on its managed hosting devices and directly provides the results to the management entity. This self-service mechanism eliminates the need for external intervention or complex centralized processing, enabling rapid capacity validation without burdening the placement optimization system.
2Productivity
If declarative infrastructure capacity information is used, then placement speed is improved, but information reliability deteriorates
Solution Approach 1:
The patent establishes a feedback mechanism where the virtualization entity continuously monitors and reports actual infrastructure capacity to the management entity. The management entity uses this feedback information to update its placement decisions, ensuring that the information used is current and reliable while maintaining fast placement speeds through automated information exchange.
Solution Approach 2:
The system pre-validates infrastructure capacity by executing tests before placement decisions are made. This preliminary verification ensures that the capacity information stored and used for placement is accurate and up-to-date, eliminating reliance on potentially outdated declarative information while maintaining placement efficiency.
3Adaptability or versatility
If infrastructure management and placement management are separated, then system modularity is improved, but information compatibility deteriorates
Solution Approach 1:
The patent introduces a standardized information exchange interface between the infrastructure management entity and the placement management entity. This intermediary mechanism ensures that capacity information and placement requests are transmitted in a compatible format, preserving information integrity while allowing the two management functions to remain separate and modular.

AI summary
Method for evaluating the devices of a network infrastructure for deploying a virtualised function. The invention relates to a method for determining a device for hosting an operator's network infrastructure for installing a virtualised function, said virtualised function contributing to the transmission and processing of at least one item of information relating to a service. The placement of virtualised functions, according to the prior art, is based on information transmitted by an entity in charge of managing the infrastructure to a controller, in charge of the placement. Said items of information are declarative and possibly not adapted to the features of the virtualised function to be deployed. This can lead to deploying virtualised functions on virtual machines or containers not prepared for or adapted to the specified virtualised functions and, consequently, to a lower quality of service offered from the virtualised functions. The invention aims to improve the prior art by carrying out tests of hosting device resources, said tests being adapted to the virtualised functions to be installed.
