Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed operational channel grid is used in DWDM, then network stability and equipment interoperability are improved, but network adaptability and flexibility in supporting multiple transponder generations are reduced
Solution Approach 1:
The patent implements dynamic cross-frequency path configuration that allows the WDM network to adaptively change operational parameters in real-time. The system dynamically adjusts frequency allocations and path configurations based on current network conditions and requirements, transforming the static fixed grid into a dynamic flexible structure that maintains stability while enabling adaptability.
Solution Approach 2:
The invention changes the operational parameters of the WDM network by introducing flexible frequency allocations and adjustable channel configurations. This allows the network to modify its operational characteristics without changing the physical infrastructure, enabling support for multiple transponder generations and formats while maintaining backward compatibility.
2Adaptability or versatility
If dynamic cross-frequency path configuration is implemented, then network adaptability and optimization are improved, but system complexity and control difficulty increase
Solution Approach 1:
The patent introduces an intelligent controller as an intermediary component that manages the complexity of dynamic cross-frequency path configuration. This controller acts as a mediator between the physical WDM infrastructure and the logical network operations, automating the configuration and optimization processes while providing a simplified interface for network management.
Solution Approach 2:
The system divides the complex task of network configuration into manageable segments by separating the control plane from the data plane. The intelligent controller handles high-level configuration decisions while individual OADM devices and transponders execute specific localized functions, reducing the complexity burden on any single component.
3Adaptability or versatility
If flexible grid or gridless DWDM is used, then support for multiple transponder generations and formats is improved, but measurement precision and channel spacing control are reduced
Solution Approach 1:
The patent implements a dynamic configuration system that can adapt channel spacing and frequency allocations in real-time based on the specific requirements of different transponder generations. The system maintains precise control over channel parameters while allowing flexible adjustments to accommodate various formats and rates, transforming static precision constraints into dynamic adaptable parameters.
