Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer systems face challenges in conserving power, particularly in managing network interface card (NIC) power consumption, as existing methods do not efficiently adjust network connection speeds based on bandwidth utilization to minimize excess bandwidth and reduce energy usage.
Innovation Solution
A method and system that determine a first network connection speed for a NIC, monitor bandwidth utilization, and adjust the NIC's operation to a second speed using a power management policy when utilization is outside a threshold range, thereby configuring the NIC to operate at optimized power consumption levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the NIC operates at high network connection speed, then bandwidth availability is improved, but power consumption increases
Solution Approach 1:
The NIC operates speed is dynamically adjusted based on actual bandwidth utilization. The system transitions from a static high-speed operation to a dynamic speed adjustment model, where the NIC can switch between different speed levels (e.g., 1000 Mbps, 100 Mbps, 10 Mbps) according to real-time network conditions, thereby optimizing the balance between performance and power consumption
Solution Approach 2:
The system changes the operational parameters of the NIC by adjusting its connection speed based on bandwidth utilization metrics. When utilization falls below a threshold, the system decreases the speed parameter to reduce power consumption, while maintaining the capability to increase speed when higher bandwidth is needed, thus adapting parameters to actual usage requirements
2Productivity
If the NIC operates at high network connection speed, then bandwidth provision is improved, but excess bandwidth is wasted
Solution Approach 1:
The system implements a feedback mechanism that continuously monitors bandwidth utilization and uses this information to adjust NIC operating speed. The feedback loop compares actual utilization against thresholds and triggers speed adjustments accordingly, ensuring that bandwidth provision matches actual demand and eliminating waste from over-provisioning
Solution Approach 2:
The NIC speed adjustment system operates autonomously by self-monitoring bandwidth utilization and self-adjusting its operational speed without requiring external intervention. The system serves itself by automatically detecting when high speed is unnecessary and transitioning to lower speed modes, thereby eliminating waste while maintaining adequate service levels

AI summary
In general, in one aspect, the invention relates to a method for conserving power. The method includes determining a first network connection speed for a network interface card (NIC), configuring the NIC to operate at the first network connection speed, processing, after the configuration, packets received by the NIC, obtaining a bandwidth utilization of the NIC, determining, using a power management policy, a second network connection speed for the NIC based on the bandwidth utilization when the bandwidth utilization is outside a threshold range, and configuring the NIC to operate at the second network connection speed.
