Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a static and manually installed topology is used, then the network structure is simple to implement, but the network cannot dynamically adjust bandwidth and topology, leading to performance degradation
Solution Approach 1:
The patent implements dynamic optical circuit switching that allows the network topology to change in real-time based on traffic demands. The system dynamically reconfigures optical connections between server groups and packet processing nodes, enabling bandwidth adjustment without manual intervention while maintaining manageable complexity through automated control.
Solution Approach 2:
The patent introduces an optical circuit switch as an intermediary device that sits between server groups and packet processing nodes. This intermediary enables dynamic topology reconfiguration by programmatically controlling optical connections, separating the complexity of dynamic adjustment from the core network infrastructure.
2Productivity
If manual rewiring is performed for topology changes, then the network hardware is simple, but the process requires manual intervention and results in network performance degradation during reconfiguration
Solution Approach 1:
The patent replaces manual mechanical rewiring with automated optical circuit switching. The system uses electronic control signals to reconfigure optical connections programmatically, eliminating the need for physical cable manipulation while maintaining simple hardware architecture. This substitution enables rapid topology changes without manual intervention.
3Reliability
If static topology structures are used, then the network is easy to manage, but fault detection capability is poor and scalability is limited
Solution Approach 1:
The patent implements feedback mechanisms where the optical circuit switch continuously monitors network conditions, traffic patterns, and link status. This feedback enables automatic fault detection and dynamic topology adjustment in response to detected issues, improving reliability while maintaining manageable complexity through automated response protocols.
