Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a specified traffic model and specific traffic characteristic are used for network traffic simulation, then the simulation can be performed with a fixed approach, but the flexibility and emulation degree of traffic simulation are reduced
Solution Approach 1:
The patent implements dynamic traffic model selection where the system automatically chooses from multiple predefined traffic models (e.g., Poisson, Markov, Fractal) based on the input traffic characteristics. This allows the simulation system to adapt its behavior dynamically rather than being fixed, thereby improving flexibility while managing complexity through automated model selection
Solution Approach 2:
The system changes parameters such as traffic intensity, arrival patterns, and packet size distributions according to the analyzed traffic characteristics. By adjusting these parameters to match real network traffic patterns, the system achieves high emulation degree without requiring a completely complex redesign of the simulation framework
2Adaptability or versatility
If multiple traffic models are provided to improve flexibility, then the emulation degree increases, but the system complexity increases
Solution Approach 1:
The system performs self-service by automatically analyzing traffic characteristics and selecting the most appropriate traffic model without requiring manual intervention. The analysis module extracts key parameters from captured traffic data, and the selection module automatically matches them with suitable predefined models, thereby reducing operational complexity while maintaining high emulation capability
Solution Approach 2:
The patent segments the traffic simulation system into distinct functional modules: traffic capture module, analysis module, model selection module, and simulation module. This segmentation allows each module to handle specific tasks independently, making the overall system more manageable despite having multiple traffic models available
