Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If intermediate nodes only forward data packets without processing, then device complexity is reduced, but data processing efficiency deteriorates
Solution Approach 1:
The patent segments the network node into distinct functional modules: a data processing module that performs data processing functions and a forwarding module that handles packet forwarding. This segmentation allows the node to simultaneously process data and forward packets without increasing overall structural complexity, as each module has a dedicated function.
Solution Approach 2:
The network node is designed with multi-functionality, where the same node can both forward data packets and process data. The data processing module can perform various operations including filtering, aggregation, and transformation of data packets, making the node versatile in handling different data processing requirements while maintaining its forwarding capability.
2Productivity
If data processing functions are added to each node, then data processing capability is improved, but device complexity increases
Solution Approach 1:
The node architecture is segmented into functional modules where the data processing module handles processing tasks and the forwarding module handles packet transmission. This modular segmentation improves data processing capability while keeping the architecture manageable through clear functional separation.
Solution Approach 2:
The patent introduces a data processing module as an intermediary component between the receiving interface and the forwarding module. This intermediary module processes data packets before they are forwarded, enabling enhanced data processing capability without directly complicating the core forwarding architecture.
3Productivity
If protocol layers are deployed on each node for data processing, then data utilization is enhanced, but ease of operation deteriorates
Solution Approach 1:
The network node is designed with universal multi-functionality, supporting both data forwarding and multiple data processing operations through integrated protocol layers. This allows the same node configuration to handle various data processing tasks without requiring separate configurations for each function, thereby enhancing data utilization while maintaining ease of operation.
