Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If centralized network control is used to manage bandwidth, then network capacity can be increased, but device behavior cannot be effectively managed and network congestion occurs
Solution Approach 1:
The patent segments network control into two parts: centralized policy management (network side) and local execution (device side). The network controller establishes differential network access control policies, while device service processors execute these policies locally to monitor and control service usage activities, achieving both capacity management and effective device behavior control.
Solution Approach 2:
The patent introduces device service processors as intermediaries between the network controller and service usage activities. These processors execute network-controlled policies locally, acting as mediators that translate centralized intent into device-level actions for monitoring and controlling network service usage.
2Ease of operation
If all network service usage activities are allowed, then user experience is improved, but network capacity is depleted and congestion occurs
Solution Approach 1:
The patent applies differential network access control policies that create different levels of access control for different service usage activities. Critical services receive higher priority access while non-critical services are controlled or blocked, allowing acceptable user experience for essential services while preserving network capacity.
Solution Approach 2:
The patent dynamically changes network access parameters based on network conditions and service priority. The system monitors service usage activities and adjusts access control policies in real-time, changing parameters such as allowed bandwidth, priority levels, and access permissions to balance user experience with network capacity preservation.
3Extent of automation
If network monitoring is implemented at the network level only, then centralized control is achieved, but real-time device-level control is insufficient
Solution Approach 1:
The patent implements preliminary action by having the network controller pre-establish differential network access control policies before congestion occurs. Device service processors are pre-configured with these policies and can execute them immediately when service usage activities are detected, eliminating the time delay associated with real-time centralized decision-making.
