Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a tentative method is adopted to distinguish bit error packet loss and congestion packet loss by continuously adjusting transmission rate, then a rough determination can be obtained, but the determining process becomes complex and time-consuming
Solution Approach 1:
The patent sends test packets at different priorities before actual data transmission to pre-measure packet loss ratios. This preliminary measurement establishes a baseline that eliminates the need for continuous rate adjustment attempts during actual operation, significantly reducing determination time while maintaining accuracy.
Solution Approach 2:
The patent uses test packets as copies of actual data packets to measure packet loss characteristics. By analyzing the packet loss ratios of these test packets at different priorities, the system can determine the packet loss reason without needing to continuously adjust and test actual data transmission, thus avoiding time-consuming iterative processes.
2Measurement precision
If continuous rate adjustment attempts are made to determine maximal traffic value, then a rough determination can be obtained, but the determining process becomes complex and efficiency is reduced
Solution Approach 1:
The system performs packet loss measurement using test packets at different priorities before actual data transmission begins. This preliminary action provides the necessary information to determine packet loss reasons without requiring continuous rate adjustment attempts during productive operations, thereby maintaining high determination efficiency.
Solution Approach 2:
The patent introduces test packets as an intermediary to measure packet loss characteristics. These test packets serve as a mediator between the system and the network conditions, allowing accurate determination of packet loss reasons without requiring continuous adjustment of actual data transmission rates, thus maintaining high productivity.
3Device complexity
If a single transmission link is used for packet loss measurement, then the measurement process is simple, but the accuracy of distinguishing bit error and congestion packet loss is insufficient
Solution Approach 1:
The patent segments the packet loss measurement by using multiple transmission links with different priorities. Each link provides information about packet loss under different service priority conditions. By analyzing the differential packet loss ratios across these segmented links, the system can accurately distinguish between bit error and congestion causes, achieving high precision without excessive complexity.
Solution Approach 2:
The patent applies different service priorities to different transmission links, creating local quality differences in the measurement system. High priority links and low priority links experience packet loss differently under congestion versus bit error conditions. By measuring packet loss ratios at these different local qualities (priorities), the system can accurately determine the packet loss reason.
