Network Port Lane Control for Autonomous Energy Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of controlling network devices in data centers for prompt energy consumption adjustments hinders efficient energy management, as existing methods require network devices to negotiate or be controlled by a central authority for lane status adjustments.
Innovation Solution
A control method and apparatus that enable or disable ports or lanes in network devices based on energy saving strategies and performance data, allowing devices to adjust their status independently without negotiation, thereby simplifying the control process and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If network devices send signaling for mutual confirmation and are controlled by a central authority to adjust lane status, then energy consumption adjustments can be made, but the control process becomes complex and slow
Solution Approach 1:
The network device autonomously determines lane status adjustments by monitoring its own performance data (bandwidth usage, queue depth) against energy saving strategies, eliminating the need for complex negotiations with other devices or central controllers. The device self-manages energy consumption by independently enabling or disabling lanes based on real-time performance metrics.
2Productivity
If network devices autonomously adjust port or lane status based on performance data, then control process is simplified and adjustment speed is improved, but energy saving effectiveness may be reduced without centralized coordination
Solution Approach 1:
The network device continuously monitors performance data (interface bandwidth usage ratio and queue depth) and uses this feedback to dynamically adjust lane status. The device compares real-time performance metrics against energy saving strategies to determine whether to enable or disable lanes, creating a closed-loop control system that balances energy savings with performance requirements.
Solution Approach 2:
The energy saving strategy includes configurable parameters such as bandwidth usage thresholds and queue depth thresholds that determine when lanes should be disabled. By adjusting these parameters, the system can optimize the balance between energy consumption and performance, allowing flexible adaptation to different operational requirements without centralized control.
3Loss of energy
If multiple network devices negotiate with each other for lane status adjustments, then energy consumption can be coordinated, but the negotiation process increases system complexity
Solution Approach 1:
The patent extracts the energy management function from the complex inter-device negotiation process and implements it locally within each network device. By taking out the decision-making authority from centralized coordination and placing it at the device level, the system eliminates the need for signaling negotiations while maintaining effective energy management through local performance monitoring and autonomous lane status adjustment.
