MAC Address Priority Filtering for Virtual Node Memory Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computing environments, managing packet filters for virtual nodes over physical network interfaces is challenging due to memory constraints, especially when dealing with nested virtual nodes, as it is difficult to determine which virtual nodes receive packet filters effectively.
Innovation Solution
A method is introduced that involves obtaining dispatch statistics for MAC addresses associated with virtual nodes, identifying priority values based on virtual and physical network interface information, and applying filter configurations to ensure adequate processing resources by directing packets into appropriate processing queues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packet filters are implemented for all virtual nodes, then quality of service is improved, but memory constraints are violated
Solution Approach 1:
The patent applies local quality by differentiating treatment based on MAC address priority levels. High-priority MAC addresses receive packet filters with full quality of service, while low-priority MAC addresses receive reduced or no filtering. This allows the system to allocate memory resources selectively rather than uniformly, resolving the contradiction between providing quality of service to all virtual nodes and maintaining within memory constraints.
Solution Approach 2:
The patent changes the parameter of filter application based on priority values assigned to MAC addresses. By modifying which virtual nodes receive packet filters according to their priority status, the system dynamically adjusts memory consumption while maintaining quality of service for critical traffic. This parameter-based differentiation enables the system to operate within memory constraints while still providing enhanced service where needed.
2Reliability
If packet filters are applied to nested virtual nodes, then communication control is improved, but classification difficulty increases
Solution Approach 1:
The patent introduces MAC address priority as an intermediary classification mechanism between the physical network interface and nested virtual nodes. Instead of directly classifying complex nested virtual node traffic patterns, the system uses the simplified MAC address priority information as a mediator to determine filter application. This intermediary approach significantly reduces classification difficulty while still enabling effective communication control for nested virtual nodes.
Solution Approach 2:
The patent segments the virtual node population into priority-based groups (high-priority and low-priority MAC addresses). This segmentation simplifies the classification problem by dividing the complex set of nested virtual nodes into manageable categories with different filtering requirements. The segmentation approach reduces the computational complexity of classifying packets for nested virtual nodes while maintaining precise communication control.
3Productivity
If more packet filters are implemented, then virtual node communication is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service by having the system automatically determine which virtual nodes receive packet filters based on their MAC address priority values and dispatch statistics. Rather than requiring manual configuration or complex centralized management, the system autonomously makes filter allocation decisions. This self-service approach reduces filter management complexity while still optimizing virtual node communication performance.
Solution Approach 2:
The patent uses parameter changes in priority values and dispatch statistics to automatically control filter application. By dynamically adjusting which virtual nodes receive filters based on real-time parameters, the system optimizes communication performance without requiring complex static configuration. This parameter-driven automatic allocation significantly reduces device complexity compared to manual filter management approaches.

AI summary
Described herein are systems, methods, and software to enhance the management of packet filters for host computing systems. In one implementation, a computing system may identify media access control (MAC) addresses and communication statistics for virtual nodes communicating over physical network interfaces of the computing system. The computing system may further prioritize the MAC addresses based on the virtual network interface ports and physical network interface ports that the MAC addresses were identified on, and generate a filter configuration for the physical network interfaces based on the prioritization and the communication statistics.
