Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If historical traffic analysis is used for energy efficiency control, then implementation simplicity is maintained, but real-time responsiveness and accuracy of energy management deteriorates
Solution Approach 1:
The system performs preliminary actions by continuously collecting and analyzing network traffic data to train machine learning models in advance. These models predict future traffic patterns before they occur, enabling the energy efficiency controller to proactively adjust network parameters and device states ahead of actual traffic changes, thus achieving real-time responsiveness without complex on-the-fly analysis
Solution Approach 2:
The patent introduces machine learning models as intermediary components between raw historical traffic data and energy efficiency control decisions. These models act as mediators that process historical data and generate predictive insights, which then guide the control policy. This intermediary layer enables accurate real-time predictions while keeping the control implementation relatively simple and modular
2Loss of energy
If link-specific control policies are implemented, then local energy optimization is achieved, but overall network energy efficiency deteriorates due to lack of broader context
Solution Approach 1:
The patent merges link-specific control policies with network-wide traffic predictions by integrating local energy optimization decisions with global network context. The system combines measurements from multiple links and uses centralized machine learning models to coordinate control actions across the network, ensuring that local power savings contribute to overall network energy efficiency rather than operating in isolation
Solution Approach 2:
The control policy framework is designed to be universal and multi-functional, serving both local link optimization and global network energy efficiency goals. The same machine learning-based prediction engine and control architecture are applied across multiple links and network nodes, enabling the system to adapt to different traffic patterns and optimization requirements while maintaining a unified approach to energy management
3Loss of energy
If dynamic control policies adjust to traffic patterns, then energy efficiency improves, but system complexity and difficulty of implementation increases
Solution Approach 1:
The patent implements dynamic control policies that automatically adapt to changing traffic patterns through machine learning models. These models continuously learn from historical data and adjust predictions based on observed traffic variations, enabling the system to dynamically optimize energy efficiency without requiring manual reconfiguration or complex rule-based logic. The dynamics are built into the learning algorithm itself
Solution Approach 2:
The system employs self-service mechanisms where the machine learning models automatically train on collected traffic data and generate control decisions without external intervention. The control policy serves itself by using its own performance data to improve future predictions and adjustments, reducing the need for complex external control logic and manual tuning while maintaining high energy efficiency
Data Source
AI summary
An auto-aware dynamic control policy for energy efficiency. A discovery node in a network can be designed to transmit periodically discovery traffic to a plurality of other network nodes in the network. Responses to the discovery traffic can be used by the discovery node to ascertain real-time activity in the network. Measures of the real-time activity can be used to adjust a control policy in the discovery node.
