Network Device Power Control via Dynamic Capability Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-speed communication systems like 1Gbase-T/10Gbase-T Ethernet, power consumption increases with frequent circuit operation and the number of transport ports, and existing power-saving methods, such as adjusting network device parameters, result in inefficiencies due to reserved margins to avoid errors.
Innovation Solution
A power consumption control method that involves checking the receiving capability of one network device and selectively notifying the other to adjust its transmitting capability, using a notice signal to lower or raise the transmitting power based on thresholds, and employing a fallback mechanism to prevent errors.

Engineering Contradiction Analysis
1Use of energy by moving object
If the transmitting capability or receiving capability of a network device is lowered to save power, then power consumption is reduced, but communication reliability deteriorates due to errors
Solution Approach 1:
The patent implements a feedback mechanism where network devices exchange capability information and adjust transmitting/receiving capabilities based on actual communication conditions. The first network device checks its receiving capability and notifies the second network device, which then adjusts its transmitting capability accordingly. This feedback loop allows dynamic adaptation to maintain reliability while saving power.
Solution Approach 2:
The patent makes the transmitting and receiving capabilities dynamic rather than static. Network devices can adjust their capabilities in real-time based on actual communication conditions and received notifications from the other side. This dynamic adjustment allows the system to optimize power consumption while maintaining reliability through continuous adaptation.
2Reliability
If a margin is reserved to avoid errors when lowering transmitting capability, then communication reliability is maintained, but power-saving performance deteriorates due to wasted power
Solution Approach 1:
The feedback mechanism eliminates the need for conservative margins by using actual capability information exchanged between devices. The first network device checks its receiving capability and provides this information to the second network device, which then sets its transmitting capability precisely according to actual conditions rather than using reserved margins, thereby optimizing power savings.
Solution Approach 2:
The patent changes the parameters of transmitting and receiving capabilities based on actual measured capability values. Instead of using fixed margins, the system dynamically adjusts capabilities according to the actual receiving capability checked by the first network device and communicated to the second network device, achieving optimal power-saving performance.
3Reliability
If network devices continuously operate at high capability, then communication reliability is maintained, but power consumption increases
Solution Approach 1:
The patent implements dynamic capability adjustment where network devices can operate at different capability levels depending on actual conditions. The system transitions from continuous high-capability operation to dynamic capability modulation, allowing devices to operate at lower capabilities when conditions permit, thereby reducing power consumption while maintaining reliability through real-time adaptation.
Solution Approach 2:
The system dynamically changes the operating parameters (transmitting and receiving capabilities) of network devices based on actual capability checks and notifications. This parameter modulation allows the system to optimize the balance between power consumption and communication reliability by adjusting capabilities to match actual operational conditions.

AI summary
A communication system includes a first network device and a second network device. A power consumption control method applied to the communication system includes the steps of: checking a receiving capability of the first network device to generate a first checking result; and selectively notifying the second network device to adjust a transmitting capability of the second network device according to the first checking result. When the first checking result indicates that the receiving capability of the first network device is greater than a first threshold, transmit a first notice signal to notify the second network device. When receiving the first notice signal, lower the transmitting capability of the second network device.
