Power-Efficient Adaptive Link Aggregation for Network Switches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In EtherChannel configurations, existing methods lead to unnecessary power consumption due to all physical ports being kept operational, even during low-load conditions, resulting in underutilization and increased energy expenditure.
Innovation Solution
Implement a power-efficient configuration where active physical ports are dynamically switched to standby mode during low-load conditions and vice versa based on negotiated parameters and bandwidth thresholds, ensuring only necessary ports are active, thereby minimizing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all physical ports are kept operational in EtherChannel to handle potential high load, then network reliability and bandwidth capacity are improved, but power consumption increases unnecessarily during low-load conditions
Solution Approach 1:
The patent implements dynamic port configuration where physical ports transition between active and standby states based on real-time load monitoring. The system continuously assesses bandwidth utilization and automatically activates or deactivates ports to match actual network demand, resolving the contradiction between maintaining reliability and reducing power consumption.
Solution Approach 2:
The system changes the operational state parameter of physical ports from static (always on) to dynamic (conditional activation). By monitoring load parameters and adjusting port states accordingly, the system maintains network reliability when needed while minimizing power consumption during low-utilization periods.
2Productivity
If multiple physical ports are actively used in port aggregation, then bandwidth capacity and load handling capability are improved, but device complexity and power consumption increase
Solution Approach 1:
The patent segments the physical ports into distinct active and standby groups, allowing selective activation based on load requirements. This segmentation enables the system to maintain high bandwidth capacity when needed while reducing operational complexity by keeping only necessary ports active, thus resolving the contradiction between productivity and device complexity.
3Adaptability or versatility
If all physical ports remain active to cater to potential load requirements, then network adaptability and service availability are improved, but power efficiency deteriorates
Solution Approach 1:
The system implements a feedback mechanism that continuously monitors network load and adjusts port activation states accordingly. This closed-loop control maintains network adaptability by activating ports when load increases while improving energy efficiency by deactivating ports during low-utilization periods, thus resolving the contradiction between adaptability and energy loss.

AI summary
A method for power-efficient configuration of one or more physical ports at a network device in an EtherChannel is provided. Parameters for allocation of the physical ports to a logical port are negotiated with a link partner. Thereafter, bandwidth load at the logical port is compared with the parameter. The physical ports are configured, based on the comparison.
