NFV Network Service Lifecycle Management via VNF Instance Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network functions virtualization (NFV) technologies face low instantiation processing efficiency and resource wastage due to inefficient management of virtualized network functions (VNFs) during network service instantiation.
Innovation Solution
A life cycle management method that identifies and utilizes existing VNF instances for instantiating network services, optimizing resource utilization by matching instantiated VNF instances with requirement information and establishing mapping relationships between identifiers and characteristic parameters to streamline the instantiation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If VNF instances are created independently for each network service without reusing existing instances, then service deployment flexibility is improved, but resource utilization deteriorates and instantiation processing efficiency decreases
Solution Approach 1:
The system performs preliminary actions by creating a mapping relationship between VNF instance identifiers and characteristic parameters before network service instantiation. This pre-established mapping enables direct reuse of existing VNF instances during service deployment, eliminating the need to create independent VNF instances for each service while maintaining deployment flexibility.
2Productivity
If VNF instances are reused across multiple network services, then resource utilization is improved, but the complexity of managing and tracking VNF instances increases
Solution Approach 1:
The system introduces an intermediary mapping relationship between VNF instance identifiers and characteristic parameters. This mapping acts as a mediator that enables VNF instances to be reused across multiple network services while providing clear tracking and management mechanisms. The mapping relationship simplifies the complexity by establishing structured associations rather than requiring complex direct management of shared instances.
3Speed
If existing VNF instances are not matched with network service requirements, then instantiation speed is improved, but resource waste increases
Solution Approach 1:
The system implements feedback by establishing a mapping relationship between VNF instance identifiers and characteristic parameters that describes the requirements of network services. During instantiation, the system references this feedback information to match existing VNF instances with service requirements, enabling both fast instantiation and efficient resource utilization by avoiding unnecessary creation of VNF instances.
