Engineering Contradiction Analysis
1Adaptability or versatility
If conventional test tools are used for testing network nodes with reconfigurable features, then the test tools have fixed functionality and are easy to operate, but they are not well-suited for testing network nodes with reconfigurable features like P4-programmed devices
Solution Approach 1:
The test system automatically analyzes the DUT source code and generates configuration source code for test system resources without requiring manual configuration by operators. The system configures itself based on the functionality identified from the device source files, eliminating the need for complex manual setup while maintaining adaptability to reconfigurable network nodes
Solution Approach 2:
The system performs preliminary analysis of the device source files before actual testing begins. By identifying functionality and generating configuration source code in advance, the system prepares the test environment proactively, reducing complexity during the actual testing phase and enabling seamless adaptation to reconfigurable devices
2Productivity
If manual configuration of test systems is performed by human operators, then the configuration can be customized, but the time needed for setup is excessive
Solution Approach 1:
The system replaces the manual mechanical process of operator configuration with an automated computer-based system that analyzes source code and generates configuration automatically. This substitution eliminates human intervention in the configuration process, dramatically reducing setup time while maintaining or improving configuration quality through systematic source code analysis
Solution Approach 2:
The system introduces an intermediary automated configuration process that acts as a bridge between the device source code and the test system resources. This intermediary automatically translates source code functionality into appropriate test configurations, eliminating the time-consuming manual translation process while ensuring accurate and consistent configuration generation
