Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If packet switched networks are used to connect requester and responder devices, then device connectivity and flexibility are improved, but network congestion and high latency occur
Solution Approach 1:
The system segments the data transmission path into two distinct networks: a packet switched network for control signals and a circuit switched network for data transmission. This segmentation allows each network to optimize for its specific function, with the circuit switched network providing dedicated low-latency data paths while the packet switched network handles flexible control routing.
Solution Approach 2:
A central orchestrating unit acts as an intermediary between the packet switched network and circuit switched network. It receives data requests from the packet switched network, processes routing decisions, and establishes corresponding circuits in the circuit switched network, thereby mediating between the flexibility of packet switching and the low latency of circuit switching.
2Loss of time
If circuit switched systems are used for data transmission, then latency is reduced, but costly synchronization is required
Solution Approach 1:
The central orchestrating unit performs preliminary actions by pre-establishing circuit connections before data transmission begins. It proactively sets up the circuit switched paths and coordinates synchronization parameters in advance, eliminating the need for expensive real-time synchronization during actual data transfer operations.
3Adaptability or versatility
If more devices are added to the network, then functionality is improved, but data throughput capacity requirements increase
Solution Approach 1:
The system dynamically allocates circuit resources in the circuit switched network based on actual data transmission requests. The central orchestrating unit creates dedicated circuits only when needed, allowing the network to scale functionality without proportionally increasing the fixed capacity requirements of all devices simultaneously.
