Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed physical links are used between electrical switching nodes, then the network structure is simple and stable, but the flexibility of the switching network deteriorates and communication paths are limited
Solution Approach 1:
The patent introduces optical switching nodes that can dynamically reconfigure connection relationships between electrical switching nodes through flexible port mapping. The optical switching node changes its connection state based on communication requirements, transforming the static network into a dynamic one that can adapt to different communication scenarios while maintaining structural stability.
Solution Approach 2:
The optical switching node acts as an intermediary between electrical switching nodes, providing flexible port mapping capabilities. This intermediary component enables dynamic routing and communication path selection without requiring changes to the underlying electrical switching node structure, thus resolving the contradiction between structural stability and operational flexibility.
2Device complexity
If fixed physical links are used between electrical switching nodes, then the device complexity is reduced, but the number of available communication paths deteriorates and data exchange failure probability increases
Solution Approach 1:
The optical switching node introduces dynamic port mapping that can create multiple communication paths on demand. When data exchange failures occur or are predicted, the system can dynamically reroute traffic through alternative paths without increasing the physical complexity of the network infrastructure.
Solution Approach 2:
The system changes the mapping parameters of the optical switching node to dynamically adjust communication paths. By modifying port mapping relationships rather than physical connections, the system increases reliability through multiple routing options while maintaining simple device architecture.
3Adaptability or versatility
If flexible port mapping is implemented in optical switching nodes, then the switching network flexibility is improved, but the control complexity increases
Solution Approach 1:
The optical switching node is designed to automatically perform port mapping operations based on received control instructions. The node autonomously configures its internal connections without requiring complex external control systems, reducing overall control complexity while maintaining high flexibility in communication path establishment.
Solution Approach 2:
The system implements control mechanisms where the optical switching node receives status information and control instructions from the control node, executes port mapping adjustments, and reports back on connection status. This feedback loop enables flexible adaptability through standardized control protocols rather than complex distributed control.

AI summary
A node control method includes: A control node in the processing system deploys a target path group when R target processing nodes include at least one first node group, and controls the R target processing nodes to process R tasks in one-to-one correspondence. The first node group includes two target processing nodes that need to communicate with each other when executing corresponding tasks and that are connected to different first electrical switching nodes. The target path group includes a communication path between target processing nodes in the first node group, and the communication path passes through the first electrical switching node, an optical switching node, and a second electrical switching node.
