NFV Resource Planning for VNF Migration Bottlenecks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques for planning network resource distribution in NFV-based communication networks are limited, leading to inefficiencies in resource allocation and migration of Virtual Network Functions (VNFs), which can result in suboptimal performance and increased costs due to inadequate resource availability.
Innovation Solution
A system and method for planning the distribution of network resources in NFV-based communication networks that migrates VNF instances between processing units based on load changes and reports resource shortages, using a network resource deployment optimization module to analyze and address these shortages by determining optimal locations for resource addition or relocation.

Engineering Contradiction Analysis
1Productivity
If VNF instances are migrated between processing units based on load changes, then network performance and resource utilization are improved, but resource shortages may limit migration capability
Solution Approach 1:
The system performs preliminary resource planning and provisioning before VNF migration is needed. The network resource deployment optimization module pre-identifies resource shortages and plans resource addition or relocation in advance, ensuring that resources are available when migration is required, thus preventing migration failures due to resource unavailability.
Solution Approach 2:
The system implements continuous monitoring of network resource usage and VNF load conditions. The optimization module receives feedback on resource shortages and migration requirements, dynamically adjusts resource allocation plans, and coordinates resource provisioning with migration operations to ensure seamless VNF relocation while maintaining optimal network performance.
2Productivity
If network resources are optimized for VNF migration, then resource utilization is enhanced, but hardware deployment complexity increases
Solution Approach 1:
The network resource deployment optimization module serves multiple functions: it monitors resource usage, plans resource provisioning, coordinates VNF migration, and optimizes overall network performance. By consolidating these diverse functions into a single multi-functional system, the patent reduces the need for separate specialized components, thereby managing deployment complexity while achieving comprehensive resource optimization.
Solution Approach 2:
The system dynamically adjusts resource allocation parameters based on network conditions and migration requirements. The optimization module modifies resource distribution parameters, processing unit capacity parameters, and migration timing parameters to achieve optimal resource utilization without requiring permanent complex hardware configurations, thus balancing performance gains with deployment simplicity.

AI summary
A system, method, and computer program product are provided for planning distribution of one or more network resources in a Network Function Virtualization based (NFV-based) communication network. In use, at least one Virtual Network Function (VNF) instance of a VNF is migrated between processing units in a NFV-based communication network, according to a change of load. Further, a lack of at least one network resource associated with at least one network node is reported for planning distribution of one or more network resources in the NFV-based communication network, the missing network resource at least partially limiting migration of one or more VNF instances.
