Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional spanning tree protocol is used for network topology change, then network stability is maintained, but convergence speed is slow
Solution Approach 1:
The patent implements dynamic path cost adjustment based on real-time traffic load monitoring. When congestion is detected on primary paths, the system dynamically modifies path costs to redirect traffic through alternative paths, enabling rapid adaptation to topology changes while maintaining network stability through controlled, monitored adjustments
2Productivity
If static path costs are used in network routing, then configuration simplicity is maintained, but load balancing efficiency deteriorates
Solution Approach 1:
The system performs self-service through automatic traffic load monitoring and autonomous path cost adjustment. The traffic monitoring module continuously tracks link utilization, and when congestion thresholds are exceeded, the system automatically recalculates and updates path costs without manual intervention, achieving efficient load balancing while keeping operational complexity low
Solution Approach 2:
The patent implements a feedback mechanism where traffic load information is continuously monitored and fed back to the path cost calculation module. This closed-loop system uses real-time traffic data to dynamically adjust path costs, ensuring optimal load balancing adapts to changing network conditions while maintaining simple configuration through automated decision-making

AI summary
A dynamic network load regulating device includes a first network bridge, a second network bridge, a third network bridge, and a traffic monitoring module. The second network bridge and the third network bridge are further coupled to a plurality of terminal devices. Each of the network bridges includes a plurality of ports. The traffic monitoring module is configured to monitor the status of each of the at least one data transmission path associated with the second network bridge and the at least one data transmission path associated with the third network bridge. When one or more transmission path is in a congestion condition, the traffic monitoring module dynamically updates the path cost of each data transmission path to select a second data transmission path to transmit network data. A method for the dynamic network load regulating device is also provided.
