Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual traffic switching is performed on operation services one by one during optical fiber maintenance or site addition, then the existing network service can be maintained, but labor costs increase and service disruption risk increases due to manual misoperation
Solution Approach 1:
The system performs automatic service migration and traffic switching without human intervention. The SDN controller automatically identifies affected services, calculates migration routes, and executes the cut-over process, eliminating manual operations while maintaining service integrity through automated error-free execution
Solution Approach 2:
Manual mechanical operations are replaced by an automated software-based SDN controller system. The controller uses electronic topology data and automated algorithms to perform service migration, substituting human operators with an intelligent system that reduces both labor costs and error rates
2Reliability
If manual traffic switching is performed on operation services one by one during optical fiber maintenance or site addition, then the existing network service can be maintained, but service disruption risk increases due to manual misoperation
Solution Approach 1:
The SDN controller continuously monitors service status and provides feedback during the migration process. It tracks service migration progress, detects anomalies, and adjusts the cut-over execution accordingly, ensuring service integrity through real-time feedback control that prevents misoperations
Solution Approach 2:
The automated system self-manages the entire service migration process without human intervention, eliminating the risk of manual misoperation. The system autonomously identifies services, calculates routes, and executes migration while maintaining service integrity through built-in error prevention mechanisms
3Productivity
If automated service migration is performed using SDN controller based on topology resources, then labor costs decrease and service integrity is ensured, but system complexity increases
Solution Approach 1:
The SDN controller acts as an intermediary between the physical optical network and the management system. It abstracts the complex topology management and service migration logic into a centralized controller, simplifying the overall system architecture while enabling automated operations
Solution Approach 2:
The SDN controller performs multiple functions including topology management, service identification, route calculation, and cut-over execution within a single unified platform. This multi-functionality consolidates system complexity into one versatile component rather than requiring separate systems for each function
