Power-Limited Network Switch Routing Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network switches often block traffic even when they haven't reached their theoretical maximum throughput, due to power limitations, leading to inefficiencies in data routing.
Innovation Solution
A method and system for power limited switching and routing that determine and rank routes based on power consumption, selecting the route requiring the least power for data communication between devices, considering bandwidth availability and current/prior power consumption, to optimize data routing and avoid power-intensive nodes.

1Productivity
If conventional network switches operate at maximum throughput, then data transmission speed is improved, but power consumption increases causing traffic blocking
Solution Approach 1:
The network switch dynamically adjusts its operating state based on power availability. The system transitions between different switching modes (full throughput, reduced throughput, or blocking) depending on the current power consumption level and available power budget, allowing the switch to adapt its performance characteristics to power conditions rather than operating at fixed maximum capacity
Solution Approach 2:
The invention changes the operational parameters of the network switch by introducing power consumption as a key parameter alongside throughput. The switch monitors power consumption metrics and adjusts routing decisions, bandwidth allocation, and traffic forwarding rates to maintain operation within power constraints while maximizing data transmission efficiency under available power conditions
2Use of energy by moving object
If network switches block traffic due to power limitations, then power consumption is reduced, but network efficiency and throughput are worsened
Solution Approach 1:
Instead of completely blocking traffic when power limits are approached, the system performs partial action by allowing some traffic to pass through at reduced rates or by prioritizing certain traffic flows over others. This enables the network to maintain partial functionality and efficiency even under power constraints, rather than binary on/off operation
Solution Approach 2:
The network switch implements feedback mechanisms that continuously monitor power consumption levels, traffic patterns, and network conditions. Based on this feedback, the system dynamically adjusts routing decisions, bandwidth allocation, and traffic prioritization to optimize network efficiency within power constraints, creating a closed-loop control system that adapts to changing conditions

AI summary
Communication devices may determine routes and/or may select a route for communicating data between a first communication device and a second communication device. The selected route may require the least power consumption. The determined routes may be ranked based on an amount of power required for routing the data. The data may be routed among devices based on the ranking. Power consumption of a device may be determined based on a bandwidth associated with the device. Route selection may be based on availability of power for power sources of the communication devices. The selection of routes may be based on a current power consumption and/or a history of prior power consumption of the communication devices. The selection of a route which may require least power consumption may be optimized based on the availability of bandwidth.
