Engineering Contradiction Analysis
1Productivity
If a conventional OLT with line card and main control board is used, then the optical processing capability is sufficient, but the device complexity and cost increase
Solution Approach 1:
The OLT is divided into multiple independent optical processing modules, each capable of autonomous optical packet processing. Each module includes its own processing unit and interface units, eliminating the need for complex centralized control boards and line cards while maintaining sufficient processing capability through distributed architecture.
Solution Approach 2:
Each optical processing module is designed as a universal unit that can handle multiple functions including optical packet reception, processing, and transmission. The modules can be interconnected through third interfaces to form flexible configurations, replacing the specialized line cards and control boards with multi-functional units.
2Device complexity
If a SOC-based OLT with small capacity is used, then the device complexity is reduced, but the processing capability and port quantity decrease
Solution Approach 1:
Instead of using a single SOC with limited capacity, the system segments the processing function into multiple optical processing modules. Each module maintains simplified structure while the collective system achieves high processing capability through parallel processing across multiple modules.
Solution Approach 2:
The system transitions from a single-dimensional SOC architecture to a multi-dimensional modular architecture. Multiple modules can be interconnected through third interfaces, enabling horizontal scaling of processing capability while each individual module remains simple in structure.
3Productivity
If multiple optical processing modules are interconnected through third interfaces, then the system capacity and port quantity increase, but the bandwidth allocation complexity increases
Solution Approach 1:
The processing unit receives bandwidth allocation information from the interface unit and uses this feedback to dynamically adjust data transmission between optical processing modules. The interface unit monitors the actual data bandwidth of third interfaces and provides feedback for optimization, enabling automatic bandwidth management without complex manual configuration.
Solution Approach 2:
The system implements dynamic bandwidth allocation where the processing unit can flexibly adjust data routing and bandwidth distribution based on real-time network conditions. The bandwidth allocation information is dynamically updated and applied to optimize data flow across interconnected modules without requiring complex static configuration.
