Interconnect Device Power Profiling for Traffic-Adaptive Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional switches consume excessive power during periods of low traffic due to inefficient operation at full capacity, leading to unnecessary high power consumption.
Innovation Solution
Implementing power profiles in interconnect devices to monitor and manage ingress and egress bandwidth and power consumption, adjusting thresholds to limit data traversal and power usage based on demand, thereby reducing overall power consumption.

1Use of energy by moving object
If switches operate at full capacity, then bandwidth capability is maintained, but power consumption becomes excessively high during low traffic periods
Solution Approach 1:
The switch dynamically adjusts its operational state based on traffic conditions. During low traffic periods, the switch transitions to a low-power state where bandwidth capability is reduced but power consumption is significantly lowered. During high traffic periods, the switch transitions back to full capacity operation. This dynamic state adjustment resolves the contradiction by allowing the switch to have high bandwidth capability only when needed while consuming less power during low demand periods.
Solution Approach 2:
The switch changes key operational parameters including bandwidth capability and power consumption levels based on traffic conditions. By monitoring traffic load and adjusting parameters such as port operational states, buffer sizes, and processing intensity, the switch optimizes the trade-off between bandwidth capability and power consumption, achieving high productivity when necessary and low power consumption during low traffic periods.
2Productivity
If switches reduce power consumption during low traffic, then energy efficiency improves, but bandwidth capability may be insufficient when traffic increases
Solution Approach 1:
The switch performs preliminary monitoring of traffic conditions and proactively adjusts its operational state before traffic demands increase. By detecting early signs of increasing traffic load, the switch can transition from low-power state to full capacity state in advance, ensuring bandwidth capability is available when needed while minimizing power consumption during the transition period.
Solution Approach 2:
The switch implements a feedback mechanism that continuously monitors traffic load and adjusts bandwidth capability and power consumption accordingly. When traffic increases, the feedback loop triggers an increase in bandwidth capability and power consumption. When traffic decreases, the feedback loop reduces both parameters. This closed-loop control resolves the contradiction by ensuring the switch has sufficient bandwidth capability when traffic increases while maintaining low power consumption during low traffic periods.

AI summary
An interconnect device is provided. In one example, an interconnect device includes ports and a power profile controller to receive a power profile, monitor one or more of data traversing the switch and power consumption of the switch, and during a first time period determine at least one of an ingress bandwidth exceeds a first bandwidth threshold and the power consumption exceeds a first power threshold. At least one of the first bandwidth threshold and the first power threshold is defined in the power profile. During the first time period, the power profile controller is to, in response to determining the at least one of the ingress bandwidth exceeds the first bandwidth threshold and the power consumption exceeds the first power threshold, limit one or more of the data traversing the switch and the power consumption of the interconnect device.
