Bandwidth-Based VRRP Master Node Designation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In information handling systems, the designation of a virtual router redundancy protocol (VRRP) master node based on predetermined node priority can lead to suboptimal data transmission speeds due to connections being slower than the network's capabilities, as priority values may not accurately reflect actual bandwidth capabilities.
Innovation Solution
Designating the VRRP master node based on connection bandwidth instead of predetermined node priority, where the intermediary information handling system with the higher bandwidth connection to a client system is selected as the master node, and the other as the backup, ensuring traffic is routed through the fastest available connection.

Engineering Contradiction Analysis
1Speed
If VRRP master node is designated based on predetermined node priority, then node selection is simple and stable, but data transmission speed may be suboptimal due to mismatch between priority and actual bandwidth capability
Solution Approach 1:
The patent changes the selection parameter from static priority values to dynamic bandwidth measurements. The VRRP master node selection now considers actual connection bandwidth between candidate nodes and client systems, allowing the system to adapt to changing network conditions and select the optimal master node based on real-time performance capabilities rather than predetermined configurations.
2Productivity
If VRRP master node is designated based on connection bandwidth, then data transmission speed is optimized, but node selection process becomes more complex
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously measures connection bandwidth between VRRP candidate nodes and client systems, then uses this measured data to inform master node selection decisions. This feedback loop ensures that the system adapts to actual network conditions, selecting the master node that provides the highest bandwidth connection, thereby optimizing data transfer efficiency while maintaining automated operation.

AI summary
A first information handling system may determine a first bandwidth of a first connection between the first information handling system and a client information handling system. The first information handling system may also determine a second bandwidth of a second connection between a second information handling system and the client information handling system. The first information handling system may determine that the first bandwidth is greater than the second bandwidth. Based on the determination, the first information handling system may be designated as a VRRP master node based. Based on the designation as the VRRP master node, the first information handling system may control VRRP operation of the first and second information handling systems.
