Power-Aware Transport Routing Across Network Domains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current service routing across transport networks does not consider power-related information, limiting the ability of network operators to select optimal routes based on power efficiency and environmental impact, which contributes to a significant carbon footprint.
Innovation Solution
A dynamic transport system that utilizes a central domain controller or domain management controllers to collect and calculate power-related metrics across network elements, enabling the identification and selection of power-efficient service routes through open APIs, considering factors like power consumption, greenhouse gas emissions, and local environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If service routing is based on traditional criteria (route length and available capacity), then routing simplicity is maintained, but power efficiency and environmental impact optimization are lost
Solution Approach 1:
The patent introduces an intermediary component (routing determination module or controller) that collects power-related information from network elements and processes it to determine optimal routes. This intermediary handles the complexity of power metric calculation and presentation, allowing the core routing function to remain relatively simple while achieving power efficiency optimization through the added layer of intelligence.
2Adaptability or versatility
If power-related metrics are collected and calculated across all network elements, then power-efficient route selection is enabled, but system complexity and data processing requirements increase
Solution Approach 1:
The patent segments the power metric collection and processing function into distributed components at individual network elements (which collect and provide their own power data) and a centralized routing determination module (which aggregates data and calculates optimal routes). This segmentation allows adaptability in route selection while distributing system complexity across multiple manageable components rather than concentrating it in a single complex system.
3Object-affected harmful factors
If real-time power metrics are monitored and presented for route selection, then environmental impact is reduced, but measurement and data processing complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where network elements provide their power-related information to the routing determination module, which then uses this feedback to calculate and present power metrics for different candidate routes. This feedback loop enables real-time optimization of carbon footprint by routing decisions while managing measurement complexity through structured information collection and processing protocols.
