Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network configurations lack efficient methods to dynamically assign and manage packet destinations to virtual network stacks based on specific network parameters, leading to resource inefficiencies and increased management overhead.
Innovation Solution
A method and system that dynamically create and assign packet destinations to virtual network stacks based on network configurations, allowing for one-to-one or many-to-one mappings, where packet destinations with matching configurations share virtual network stacks and those with unique configurations create new stacks, optimizing resource utilization and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate virtual network stack is created for each packet destination, then network configuration flexibility and isolation are improved, but system complexity and resource overhead increase
Solution Approach 1:
The patent segments the network stack functionality by introducing virtual network stacks that can be independently configured and assigned to different packet destinations. Each virtual network stack represents a segmented instance of network processing capabilities, allowing independent configuration while sharing underlying hardware resources. This segmentation enables flexible network configurations for different destinations without creating entirely separate physical network interfaces.
Solution Approach 2:
The patent implements universality by designing virtual network stacks that can serve multiple packet destinations with different network configurations. A single virtual network stack instance can be shared among multiple destinations that require similar network parameters, while the system can also create dedicated stacks when needed. This multi-functionality allows the same network stack infrastructure to handle diverse networking requirements through configuration rather than physical separation.
2Measurement precision
If multiple virtual network stack instances are created, then packet routing precision and isolation are improved, but memory consumption and processing overhead increase
Solution Approach 1:
The patent merges multiple virtual network stack instances by allowing them to share common underlying resources such as memory pools, processing threads, and hardware interface connections. When packet destinations have similar network configuration requirements, their virtual network stacks are merged to share these resources, reducing total memory consumption and processing overhead while maintaining distinct routing precision for each destination through configuration differentiation.
Solution Approach 2:
The patent applies local quality by allowing each virtual network stack to have specific localized configurations for packet routing while sharing global resources. Each stack instance maintains its own routing tables, configuration parameters, and destination mappings tailored to its specific packet destinations, while simultaneously sharing common infrastructure resources. This enables precise local routing control without proportionally increasing overall system resource consumption.
3Productivity
If dynamic assignment of packet destinations to virtual network stacks is implemented, then resource utilization efficiency is improved, but management complexity increases
Solution Approach 1:
The patent implements self-service by enabling virtual network stacks to dynamically assign themselves to packet destinations based on configured criteria and available resources. The system automatically matches packet destinations with appropriate virtual network stack instances using algorithms that consider network configuration compatibility, current resource utilization, and assignment policies. This self-service mechanism reduces manual management complexity while maintaining high resource utilization efficiency through automated decision-making.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system continuously monitors resource utilization, packet routing performance, and virtual network stack assignment effectiveness. Based on this feedback, the system dynamically adjusts assignments, creates or merges virtual network stack instances, and optimizes resource allocation. This feedback-driven approach enables automatic adaptation to changing network conditions, improving resource utilization while managing complexity through closed-loop control rather than static manual configuration.
