Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If flow information is obtained using IPFIX in VPN networks, then statistical information regarding communication is improved, but completeness of network information is worsened due to lack of topology, setting, operation, and location information
Solution Approach 1:
The patent combines multiple information sources including flow information from IPFIX, topology information from routing protocols, device information from SNMP, and geographic information from location databases into a unified visualization system. This merging allows comprehensive network monitoring while maintaining the precision of flow statistics.
Solution Approach 2:
The visualization device performs multiple functions simultaneously: it collects flow statistics, retrieves topology data, obtains device information, integrates geographic locations, and generates comprehensive visualizations. This multi-functionality addresses the information completeness issue without sacrificing the precision of individual data sources.
2Loss of information
If multiple types of network information are collected and integrated, then network information completeness is improved, but system complexity is worsened
Solution Approach 1:
The system segments information collection into distinct modules: a flow information acquisition unit for IPFIX data, a topology information acquisition unit for routing data, a device information acquisition unit for SNMP data, and a geographic information acquisition unit for location data. Each module handles specific data types independently, reducing overall system complexity while maintaining completeness.
Solution Approach 2:
The patent introduces an association unit that acts as an intermediary between different information sources and the visualization unit. This mediator correlates flow information with topology, device, and geographic information, managing the complexity of integrating multiple data types through a centralized coordination layer.
3Productivity
If detailed network information is visualized, then network monitoring effectiveness is improved, but information processing time is worsened
Solution Approach 1:
The system performs preliminary actions by pre-collecting and storing topology information, device information, and geographic information in databases before they are needed for visualization. When flow information arrives, the system can quickly correlate it with pre-prepared data, reducing processing time while maintaining comprehensive monitoring effectiveness.
