Network Controller Tree Sub-structure Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network device management systems face inefficiencies in verifying and updating configuration instructions due to the need to check against entire tree structures, leading to increased computing resource consumption and time.
Innovation Solution
Implementing a tree structure with sub-structures, where each sub-structure contains a set of nodes, allowing the controller to verify instructions by checking only the relevant sub-structure corresponding to the node, rather than the entire tree structure, and utilizing a configuration table to determine node paths and names for efficient verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the controller verifies configuration instructions against the entire tree structure, then verification completeness is ensured, but computing resource consumption and verification time increase
Solution Approach 1:
The patent divides the tree structure into multiple sub-structures, where each sub-structure corresponds to a specific node or branch. When verifying a configuration instruction, the controller identifies the relevant sub-structure containing the target node and performs verification only on that subset, rather than traversing the entire tree. This segmentation reduces the search space and computational overhead while maintaining verification completeness for the specific node being updated.
2Manufacturing precision
If the controller checks the entire tree structure for each configuration update, then configuration accuracy is maintained, but time consumption increases
Solution Approach 1:
The patent extracts the specific sub-structure containing the target node from the complete tree structure. By identifying and isolating only the relevant portion of the tree that needs to be verified, the controller eliminates unnecessary traversal of unrelated branches and nodes. This extraction process maintains configuration accuracy for the target node while significantly reducing the time required for verification.
3Productivity
If the controller verifies instructions based on sub-structures only, then verification speed improves, but system complexity increases
Solution Approach 1:
The patent performs preliminary organization of the tree structure into predefined sub-structures before verification operations. Each node is pre-associated with its corresponding sub-structure identifier or path. When a configuration instruction arrives, the controller quickly locates the relevant sub-structure using this pre-established mapping, avoiding the need to dynamically analyze the entire tree structure during verification. This preliminary action enables faster verification while managing complexity through structured organization.
