Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional switches consume excessive power during periods of low traffic due to non-optimal operation, leading to inefficient power usage.
Innovation Solution
Implementing a power-aware control plane that selectively enables and disables control plane components based on packet processing requirements, reducing power consumption by maintaining only necessary components active.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control plane elements are kept active continuously, then packet processing capability is maintained, but power consumption increases unnecessarily during low traffic periods
Solution Approach 1:
The control plane elements are made dynamically configurable, allowing the system to transition between active and inactive states based on traffic conditions. The traffic detector monitors packet rates and dynamically adjusts the operational state of control plane elements, enabling the system to adapt its power consumption to actual processing needs while maintaining reliability when traffic requires full capability.
Solution Approach 2:
The system changes the operational parameter of control plane elements from a static always-on state to a dynamic state that varies with traffic conditions. By monitoring traffic intensity and adjusting the active/inactive status of control plane elements accordingly, the system optimizes the balance between packet processing capability and power consumption.
2Use of energy by moving object
If control plane elements are disabled to save power, then power consumption is reduced, but packet processing capability is compromised when needed
Solution Approach 1:
The traffic detector performs preliminary monitoring of traffic patterns to predict when control plane elements will be needed. By detecting traffic conditions in advance and proactively activating control plane elements before heavy traffic arrives, the system ensures packet processing capability is available when needed while minimizing unnecessary active time and power consumption during low traffic periods.
Solution Approach 2:
The system implements a feedback mechanism where the traffic detector continuously monitors packet processing requirements and provides feedback to the control plane element activation logic. This closed-loop control ensures that control plane elements are activated or deactivated based on actual real-time needs, preventing capability loss while optimizing power consumption.
3Productivity
If all control plane elements operate at full capacity, then packet processing performance is maximized, but power consumption is unnecessarily high during low traffic periods
Solution Approach 1:
Instead of always operating control plane elements at full capacity, the system applies partial action by activating only the necessary subset of control plane elements based on actual traffic requirements. The traffic detector identifies the minimum required processing capability and activates corresponding elements at appropriate capacity levels, avoiding excessive power consumption while maintaining sufficient packet processing performance.

AI summary
An interconnect device is provided. In one example, an interconnect device includes ports and a control circuit capable of enabling and disabling control plane components based on received packets. Enabled control plane components enable the received packets to be forwarded to a destination via an egress port. Disabled control plane components enable a reduction in power consumption.
