Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If submarine cables are used for traffic transmission, then transmission capacity and speed are improved, but reliability deteriorates when cables are abnormal or disconnected
Solution Approach 1:
The system dynamically changes the routing parameter from submarine cable to satellite network based on the connection status of the submarine cable. When the submarine cable is abnormal, the routing decision parameter is changed to use the low earth orbit satellite network instead, maintaining traffic transmission reliability while preserving high speed transmission capability when the cable is functional.
Solution Approach 2:
The adaptive satellite routing orchestration system acts as an intermediary between the traffic source and the mobile core network. It includes a packet analysis module, routing switch control module, and routing priority control module that collectively mediate the routing decision, switching traffic between submarine cable and satellite network based on real-time cable status.
2Productivity
If submarine cables are used for traffic transmission, then transmission capacity is improved, but adaptability deteriorates when cables are abnormal or disconnected
Solution Approach 1:
The routing system is made dynamic by continuously monitoring the submarine cable connection status and automatically adjusting the routing path accordingly. The routing switch control module receives cable status information and dynamically switches traffic between submarine cable and satellite network, enabling the system to adapt to changing network conditions while maintaining high transmission capacity.
Solution Approach 2:
The system changes the routing parameter based on submarine cable status. When the cable is abnormal, the routing parameter is changed to redirect traffic through the low earth orbit satellite network, thereby maintaining transmission capacity while improving adaptability to cable failures.
3Reliability
If routing switch control is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The routing control function is segmented into distinct modules: a packet analysis module for traffic classification, a routing switch control module for routing decisions, and a routing priority control module for priority management. This segmentation reduces overall system complexity by dividing complex routing control into manageable, independent functional units while maintaining high reliability.
Solution Approach 2:
The routing switch control module automatically receives submarine cable connection status information and autonomously makes routing decisions without requiring external manual intervention. The system self-adjusts traffic routing based on real-time cable status, reducing operational complexity while improving reliability through automated control.
