Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TSN network is deployed to provide deterministic transmission, then transmission performance is improved, but network monitoring capability deteriorates
Solution Approach 1:
The patent introduces OAM (Operations, Administration, and Maintenance) frames as intermediary elements to monitor TSN network performance. These special frames traverse the deterministic network and collect performance data without interfering with normal data transmission, thereby enabling network state information gathering while preserving deterministic transmission capabilities
Solution Approach 2:
The patent implements a feedback mechanism where OAM frames carry performance measurement results back to monitoring entities. The target node measures network performance using OAM frames and feeds back the results, enabling continuous monitoring and assessment of deterministic transmission performance without disrupting the primary data flow
2Reliability
If network monitoring is added to TSN, then network reliability is improved, but device complexity increases
Solution Approach 1:
The patent makes existing TSN network nodes multi-functional by enabling them to perform both deterministic data transmission and OAM-based performance monitoring. The same network switches and endpoints that forward production traffic also process OAM frames for monitoring, eliminating the need for separate dedicated monitoring hardware and reducing overall system complexity
Solution Approach 2:
The patent merges the monitoring function with the existing TSN network infrastructure. Instead of adding separate monitoring equipment, the OAM monitoring capabilities are integrated into the standard TSN switches and endpoints, combining data plane and management plane functions within the same devices
