Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optical paths are allocated without considering amplifier power, then route flexibility is improved, but power consumption of spatial multiplexing optical amplifiers increases
Solution Approach 1:
The patent performs preliminary power level calculations during the optical path allocation phase, before actual signal transmission. The system computes the number of wavelengths per core for each link and determines required amplifier power levels in advance, enabling proactive power management rather than reactive adjustments
Solution Approach 2:
The patent changes the allocation parameters by considering amplifier power levels as a constraint in the route selection process. The core selection unit evaluates multiple routing options based on their impact on amplifier power consumption, selecting routes that balance flexibility with power efficiency
2Ease of operation
If wavelength utilization is not leveled across the network, then allocation simplicity is improved, but overall network power efficiency deteriorates
Solution Approach 1:
The patent applies equipotentiality by leveling the number of wavelengths allocated per core across different links in the network. The core selection unit ensures that wavelength utilization is balanced, preventing situations where some amplifiers operate at high power while others are underutilized, thereby improving overall network power efficiency
Solution Approach 2:
The patent incorporates feedback mechanisms where the system monitors wavelength utilization patterns and adjusts future allocations based on observed power consumption patterns. The utilization condition information is continuously updated to reflect current network state, enabling adaptive optimization
