Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtualized network function management systems face challenges in efficiently allocating resources when hardware requirements are not met, leading to cumbersome operations and potential service disruptions during urgent processes like auto scaling or auto healing.
Innovation Solution
A virtualized network function management apparatus that includes an orchestration part, a virtualized network function management part, and a virtualized infrastructure management part, which uses priority hardware information to reserve and allocate physical resources that satisfy resource and constraint conditions, allowing for seamless resource allocation even when initial hardware options do not meet requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the VIM selects hardware based on strict flavor requirements, then resource allocation precision is improved, but deployment flexibility deteriorates when no hardware satisfies the requirements
Solution Approach 1:
The system dynamically adjusts resource allocation strategies based on deployment context. When strict flavor matching fails, the system transitions to alternative allocation modes using priority hardware information, allowing flexible adaptation between precision-oriented and flexibility-oriented allocation approaches depending on operational needs
Solution Approach 2:
The system changes the selection parameters from strict flavor matching to priority-based selection. By introducing priority levels for different hardware groups and modifying the selection criteria dynamically, the system can switch between precise flavor-based allocation and flexible priority-based allocation to resolve deployment failures
2Manufacturing precision
If manual reconfiguration is required when deployment fails, then resource allocation accuracy is maintained, but operational efficiency deteriorates
Solution Approach 1:
The system implements self-service by automatically performing resource reallocation when deployment fails. The VIM uses stored priority hardware information to autonomously select alternative hardware groups and retry deployment without requiring manual operator intervention, thereby maintaining allocation accuracy while significantly improving operational efficiency
Solution Approach 2:
The system incorporates feedback mechanisms where deployment failure information is fed back to the VIM, which then uses priority hardware information to adjust resource allocation decisions. This closed-loop feedback enables automatic correction of allocation failures while preserving allocation accuracy through informed decision-making
3Reliability
If multiple hardware groups are monitored for urgent processes, then service reliability is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-configuring priority hardware information for multiple hardware groups before urgent processes occur. This advance preparation enables rapid response to deployment failures without requiring complex real-time decision-making during critical operations, thus improving reliability while managing complexity through pre-computed allocation strategies

AI summary
A virtualized network function management apparatus includes: an orchestration part; a virtualized network function management part; a storage part that holds priority hardware information in which a combination of physical resources, for an individual virtualized network function, as a deployment candidate of the virtualized network function is associated with information about a priority set to the combination of physical resources; and a virtualized infrastructure management part. The virtualized infrastructure management part reserves a combination of physical resources that satisfies resource and constraint information necessary for the virtualized network function in accordance with the priorities in the priority hardware information. Finally, the virtualized network function management apparatus creates a virtual machine by using the reserved combination of physical resources.
