Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If discarded messages are directly discarded without processing, then the switching device maintains simple operation, but it becomes difficult to identify specific discarded packets and their reasons
Solution Approach 1:
The patent extracts discarded messages from the main data flow and directs them to a dedicated collection buffer. This separation allows the switching device to maintain simple discarding operation while preserving information about discarded packets for later analysis.
Solution Approach 2:
The patent introduces a discarded message collection processing unit as an intermediary between the functional units and the discarding process. This mediator captures discarded messages, adds identification information, and stores them without affecting the main switching operation.
2Measurement precision
If discarded messages are collected and processed, then identification of discarded packets is improved, but the device complexity increases
Solution Approach 1:
The patent segments the discarding process into distinct functional components: collection buffers for different functional units, identification information addition, and storage mechanisms. This segmentation enables precise tracking of discarded packets while organizing complexity into manageable modules.
Solution Approach 2:
The patent creates copies of discarded messages and stores them in collection buffers without affecting the original data flow. These copies contain identification information that enables precise tracking while the copying mechanism isolates the complexity from the main switching path.
3Measurement precision
If manual analysis of massive messages is performed to find discarded packets, then complete analysis can be achieved, but significant time and manpower are consumed
Solution Approach 1:
The patent performs preliminary actions by automatically collecting discarded messages, adding identification information, and storing them in organized buffers during the switching process. This preliminary processing eliminates the need for manual searching and enables rapid analysis when needed.
Solution Approach 2:
The patent establishes a feedback mechanism where discarded messages are automatically captured, tagged with identification information indicating the functional unit and port, and stored for analysis. This automated feedback loop provides complete analysis capability without manual intervention.
