Solution Overview
Problem
Current network management systems lack effective energy management, leading to inefficient power consumption as telecom equipment operates at maximum performance even during low traffic loads, resulting in unnecessary energy expenditure.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communications apparatus operate at maximum performance to handle traffic, then traffic handling capability is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the power consumption mode of communications apparatus based on real-time traffic load conditions. The power mode controller receives traffic load information from the path computation apparatus and automatically switches between different power modes (low power, medium power, high power) to match the current traffic demands, making the power consumption adaptive rather than static
Solution Approach 2:
The system changes operational parameters by selecting different power consumption modes that offer different performance-power trade-offs. Each power mode represents a different parameter configuration of the communications apparatus, allowing the system to optimize the balance between traffic handling capability and power consumption based on current network conditions
2Loss of energy
If power consumption modes are adjusted dynamically based on traffic load, then energy efficiency is improved, but response time to traffic changes may increase
Solution Approach 1:
The path computation apparatus continuously monitors and maintains up-to-date information about traffic load and power consumption modes of all communications apparatus. This preliminary action ensures that when traffic patterns change, the system already has the necessary information ready to make rapid power mode adjustments, reducing the effective response time
Solution Approach 2:
The system implements a feedback mechanism where the power mode controller continuously receives traffic load information from the path computation apparatus and adjusts power modes accordingly. This closed-loop control ensures that power consumption is continuously optimized based on actual traffic conditions, with the feedback loop operating at sufficient speed to respond to traffic changes without significant delay
3Use of energy by stationary object
If path computation is biased to use paths with lower power consumption, then overall network power consumption is reduced, but performance may be compromised
Solution Approach 1:
The path computation apparatus dynamically biases path selection toward lower power consumption modes based on current traffic load conditions and the power characteristics of available communications apparatus. This dynamic biasing allows the system to optimize overall network power consumption while maintaining sufficient performance by selecting appropriate paths based on real-time conditions rather than using a fixed routing policy
Solution Approach 2:
The path computation apparatus serves multiple functions: it computes optimal paths for traffic flow, monitors power consumption modes of communications apparatus, and biases path selection to reduce overall power consumption. This multi-functionality allows the system to simultaneously achieve both performance optimization and energy efficiency without requiring separate dedicated systems

AI summary
A network management system (NMS) for a communications network has communications apparatus capable of being operated in different power consumption modes to provide different levels of performance, has a path computation apparatus configured to select paths for the traffic using the communications apparatus, based on information about traffic load in the network and on information about the power consumption modes of the communications apparatus of at least one of the nodes. A power mode controller is also provided for controlling the power consumption modes of the communications apparatus according to information about traffic load and according to information about the paths selected. By combining of path computation and the control of power consumption modes the overall power consumption of the network can be reduced. A slave power mode controller can be provided.
