Referent System for NFV Device Location Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Network Functions Virtualization (NFV) architectures, identifying the precise physical location of devices executing network functions is challenging due to the separation of hardware and software elements, making it difficult to diagnose issues, select optimal devices for low latency or regulatory compliance, and manage device movements.
Innovation Solution
A referent system that associates network functions with referent identifier data, comprising device data and reference data, to hierarchically identify the physical location of devices within an NFV network, enabling precise location determination and selection of devices for executing network functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network functions are virtualized and separated from hardware, then flexibility and adaptability are improved, but the ability to identify precise physical location deteriorates
Solution Approach 1:
The patent introduces a location information database as an intermediary component that stores and manages the mapping relationships between virtual network functions and their physical host locations. This database acts as a mediator between the virtualized network functions and the physical infrastructure, enabling precise location identification without requiring direct hardware coupling.
Solution Approach 2:
The patent creates a virtual copy of location information by maintaining a database entry that mirrors the physical location status of host devices. This copied location data allows the system to track and identify physical locations of virtualized network functions without direct physical presence, resolving the contradiction between virtualization flexibility and location traceability.
2Adaptability or versatility
If devices are distributed across multiple locations, then system versatility and resource utilization are improved, but device management complexity increases
Solution Approach 1:
The location information database serves multiple functions simultaneously: it stores location data, enables device selection based on location criteria, supports service continuity during device movement, and provides location information for regulatory compliance. This multi-functional approach manages distributed device complexity through a single universal system.
Solution Approach 2:
The system pre-establishes location information in the database before devices are deployed or moved. By maintaining updated location data in advance, the system enables quick device selection and service migration without complex real-time discovery processes, reducing management complexity in distributed environments.
3Adaptability or versatility
If network functions can be moved between devices, then service continuity and adaptability are improved, but tracking precise location becomes more difficult
Solution Approach 1:
The system implements a feedback mechanism where the location information database is continuously updated with the current host device location whenever network functions are migrated. This feedback loop ensures that location tracking precision is maintained despite frequent function movements, enabling both service continuity and accurate location identification.

AI summary
A network functions virtualization (NFV) network can be configured to operate according to NFV protocols that decouple software functionality from specific hardware elements. A referent system can be provided that identifies a precise physical location of devices associated with the NFV network relative to other equipment or devices associated with the NFV network.
