Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optical-to-electrical conversion is performed during switching, then data exchange can be implemented using existing electrical switch technology, but processing delay and energy consumption increase
Solution Approach 1:
The patent segments the data packet into two parts: the optical label (header) and the optical signal data frame (payload). The optical label is extracted and converted to electrical signal for processing, while the optical signal data frame remains in optical domain and is switched optically without conversion. This segmentation allows selective processing of only the necessary control information while maintaining optical switching for data transmission.
Solution Approach 2:
The patent extracts the optical label from the optical data packet and separates it from the optical signal data frame. The extracted optical label is then converted to electrical signal for processing by the electrical switch control logic, while the remaining optical signal data frame is switched directly in the optical domain without requiring optical-to-electrical conversion, thereby reducing processing delay.

3Ease of operation
If all optical data packets are switched electrically, then comprehensive processing and control is achieved, but delay and energy consumption increase for packets that could be switched optically
Solution Approach 1:
The patent applies different switching qualities to different parts of the data packet: the optical label undergoes electrical processing with full control capability, while the optical signal data frame undergoes optical switching with high-speed transmission characteristics. This local differentiation of processing quality optimizes both control capability and transmission efficiency for different packet components.
Solution Approach 2:
The patent dynamically selects the switching mode based on the packet type identified in the optical label. For IP packets and other suitable protocols, optical switching is applied directly to the data frame. For packets requiring electrical processing, the system switches to electrical switching mode. This dynamic adaptation allows the system to optimize performance based on actual packet requirements.
