Engineering Contradiction Analysis
1Use of energy by moving object
If traditional routing decisions are made without energy efficiency metrics, then routing simplicity and speed are maintained, but energy consumption increases and SLA requirements may not be met
Solution Approach 1:
The system performs preliminary actions by collecting energy efficiency data from network nodes in advance using iOAM probe packets before routing decisions are made. Energy efficiency quotients are calculated and stored for multiple nodes, allowing the routing system to quickly select energy-efficient paths without performing complex real-time calculations during packet forwarding.
Solution Approach 2:
The patent introduces an intermediary mechanism (iOAM probe packets and energy efficiency quotient calculations) that mediates between traditional routing protocols and energy efficiency goals. The probe packets collect data from intermediate nodes, and the calculated quotients serve as intermediaries that translate complex energy consumption patterns into simple routing metrics that can be incorporated into existing routing decisions.
2Productivity
If energy efficiency data collection is implemented across all network nodes, then energy optimization capability is improved, but network overhead and data collection complexity increase
Solution Approach 1:
The system applies partial action by collecting energy efficiency data from only the necessary intermediate nodes along specific network paths using iOAM probe packets, rather than universally from all nodes in the network. This selective data collection approach provides sufficient information for energy-efficient routing decisions while minimizing the overhead associated with comprehensive node monitoring.
3Measurement precision
If multiple energy efficiency metrics are collected from network nodes, then routing accuracy and SLA compliance are improved, but measurement and calculation complexity increase
Solution Approach 1:
The patent extracts only the essential energy efficiency data elements needed for routing decisions from the complex set of available node metrics. By focusing on specific power consumption measurements and calculating derived quotients (such as bits per joule), the system achieves precise energy efficiency measurements for routing purposes while filtering out unnecessary measurement complexity.
