Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If network slices are deployed using traditional methods, then deployment is simple, but resource utilization is low and resource competition occurs
Solution Approach 1:
The patent segments the network deployment into two distinct layers: abstract network layer (representing network slices with virtual network functions) and physical infrastructure layer (actual network resources). This segmentation allows independent optimization of each layer while maintaining their mapping relationship, thereby improving resource utilization without complicating the deployment process.
Solution Approach 2:
The patent introduces a mapping relationship as an intermediary between the abstract network layer and physical infrastructure layer. This mapping mechanism enables efficient resource allocation by mediating the connection between virtual network slice requirements and physical resource availability, resolving the contradiction between deployment simplicity and resource utilization.
2Loss of energy
If network slices are deployed without optimization, then deployment cost is low, but network communication quality is affected
Solution Approach 1:
The patent performs preliminary optimization by establishing an optimized mapping relationship between abstract network layer nodes and physical infrastructure layer nodes before actual deployment. This preliminary action ensures that network communication quality requirements are met in advance, avoiding costly reconfigurations later while maintaining reliable communication.
Solution Approach 2:
The patent optimizes deployment by adjusting mapping parameters between network layers, such as selecting optimal physical nodes for virtual network functions based on capacity, location, and communication quality requirements. This parameter optimization ensures reliable network communication while controlling deployment costs.
3Speed
If resources are allocated without mapping optimization, then allocation is fast, but resource competition occurs
Solution Approach 1:
The patent resolves resource competition by adding a spatial dimension through layered mapping. Instead of flat resource allocation that causes competition, the patent organizes resources in hierarchical layers (abstract layer and physical layer) with explicit mapping relationships, enabling efficient resource allocation without competition by utilizing the additional structural dimension.
