Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed catalog of virtualized network functions is provided, then the infrastructure is simple to manage, but client services are limited and cannot be customized
Solution Approach 1:
The patent segments virtualized network functions into reusable elementary components (VNFCs) that can be independently configured and combined. This allows the system to offer customized services by assembling components rather than managing a complex catalog of complete VNFs, resolving the contradiction between service adaptability and catalog complexity.
Solution Approach 2:
The patent enables dynamic configuration of virtualized network functions by allowing clients to customize service parameters and combine elementary components according to specific needs. This dynamic approach replaces the static fixed catalog with a flexible composition mechanism, achieving service customization without proportionally increasing catalog complexity.
2Adaptability or versatility
If more virtualized network functions are added to the catalog, then service variety increases, but storage requirements and selection complexity increase
Solution Approach 1:
The patent merges multiple VNFs into a unified set of elementary components (VNFCs) that can be reused across different service configurations. Instead of storing separate copies of each VNF variant, the system stores reusable components that can be combined to create diverse services, reducing storage requirements while maintaining service variety.
Solution Approach 2:
The elementary components designed in the patent serve multiple functions and can be used in different combinations to create various virtualized network services. This universal design allows a single component library to support diverse service varieties without requiring proportional increases in storage capacity.
3Reliability
If compatible components are strictly verified, then system reliability improves, but configuration time increases
Solution Approach 1:
The patent implements preliminary compatibility verification by pre-defining valid combinations of elementary components and their interdependencies. The system checks compatibility during the configuration phase rather than during deployment, allowing early detection of invalid configurations and reducing rework time, thus maintaining reliability while minimizing time loss.
