Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual representations of physical devices are used in network simulations, then simulation complexity is reduced and ease of operation is improved, but feature parity between virtual and physical devices is limited, reducing measurement precision
Solution Approach 1:
The patent introduces a physical device interface as an intermediary component that connects the virtual network simulation environment to actual physical network devices. This interface layer allows virtual simulations to interact with real hardware, thereby achieving full feature parity while maintaining the ease of virtual operation. The physical device interface acts as a mediator that translates virtual operations into physical device actions and vice versa.
2Measurement precision
If physical devices are directly integrated into simulation environments, then feature parity and measurement precision are improved, but device complexity and difficulty of configuration increase
Solution Approach 1:
The patent segments the integration of physical devices into modular components managed by a physical device interface. Instead of directly integrating complex physical devices into the simulation environment, the system divides the integration task into manageable segments handled by the interface layer. This segmentation reduces the apparent complexity for users while maintaining full feature parity between virtual and physical devices.
Solution Approach 2:
The physical device interface serves as an intermediary that abstracts away the complexity of physical device integration. It handles the complex tasks of configuration, management, and coordination between virtual simulations and physical devices, thereby reducing device complexity from the user's perspective while maintaining measurement precision.
3Reliability
If physical devices are integrated within virtual network simulations, then simulation accuracy is improved, but resource consumption and device complexity increase
Solution Approach 1:
The patent implements partial integration of physical devices into virtual simulations through the physical device interface. Instead of fully integrating all physical devices at all times, the system selectively integrates only those physical devices that are currently needed for specific simulation scenarios. This partial action approach maintains simulation accuracy when needed while reducing overall resource consumption during operations that don't require physical device involvement.
