Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network transmission resources are shared, then network resource utilization is improved, but transmission delays and jitters occur for time-sensitive data
Solution Approach 1:
The patent segments network resources by introducing dedicated resources for time-sensitive data streams separate from shared resources. The network is divided into time-sensitive resource pools and general resource pools, allowing time-sensitive traffic to have guaranteed bandwidth and latency while other traffic uses shared resources, thus resolving the contradiction between resource utilization and transmission reliability.
Solution Approach 2:
The patent applies local quality by providing different resource allocation strategies for different traffic types. Time-sensitive data streams receive dedicated resource allocation with guaranteed quality parameters (latency, jitter, bandwidth), while non-time-sensitive traffic uses shared resources. This localized differentiation ensures high reliability for time-sensitive communication while maintaining overall network resource utilization.
2Reliability
If dedicated resources are reserved for time-sensitive data streams, then transmission delays are reduced, but network resource flexibility decreases
Solution Approach 1:
The patent implements dynamic resource allocation where dedicated resources for time-sensitive streams can be flexibly adjusted based on actual traffic conditions. The system can dynamically allocate, release, or adjust dedicated resource amounts according to real-time demand, ensuring that resource reservation does not permanently reduce network flexibility while maintaining transmission reliability when needed.
Solution Approach 2:
The patent makes network resources multi-functional by allowing dedicated resources to serve dual purposes: providing guaranteed service for time-sensitive streams when needed, and being available for other uses when not required by time-sensitive traffic. This universal resource usage maintains both reliability for time-sensitive communication and overall network flexibility.
3Reliability
If time-sensitive networking is implemented in wireless networks, then time-sensitive communication capability is improved, but system complexity increases
Solution Approach 1:
The patent introduces intermediary elements such as network slicing mechanisms and resource management entities that mediate between time-sensitive requirements and wireless network operations. These intermediaries handle the complexity of time-sensitive resource allocation, scheduling, and monitoring, thereby improving time-sensitive communication capability while isolating the complexity from the overall wireless network system.
