Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vendor-specific policy capabilities and languages are used in conventional broadband access networks, then network nodes can be configured with standard policies, but the degree of freedom and flexibility regarding implemented services is limited
Solution Approach 1:
The patent introduces a universal policy framework that enables multiple network nodes (programmable and configurable) to operate under a common policy management system. This universal approach allows diverse network functions to be controlled through unified policies, increasing flexibility without requiring vendor-specific configurations for each node type.
Solution Approach 2:
The patent implements dynamic service chain configuration where service chains can be automatically instantiated, modified, and terminated based on real-time demands. The system supports dynamic translation of high-level service requirements into low-level configuration commands, enabling flexible adaptation to changing network needs without manual reconfiguration.
2Productivity
If manual policy translation and configuration processes are used, then network changes can be implemented, but the process is tedious and time-consuming
Solution Approach 1:
The patent implements self-service capabilities where network nodes can automatically configure themselves based on received policies. The system includes automatic service chain instantiation, where the network autonomously translates high-level service requests into configuration commands and applies them to relevant nodes without manual intervention, significantly reducing implementation time.
Solution Approach 2:
The patent replaces manual mechanical configuration processes with automated software-based policy translation and deployment mechanisms. The system uses software-defined networking techniques to automatically translate service requirements into network configurations, eliminating the need for manual command entry and reducing human error.
3Adaptability or versatility
If dynamic changes are limited to customer-initiated requests, then network stability is maintained, but the network cannot proactively adapt to changing requirements
Solution Approach 1:
The patent implements feedback mechanisms where the network can monitor service usage patterns and automatically trigger policy adjustments. The system includes feedback loops that detect network conditions and customer usage patterns, then automatically initiate service chain modifications or optimizations without requiring explicit customer requests, thereby maintaining stability while enabling proactive adaptation.
