Server Network Abnormality Detection via Topology Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of switches in a network increases, checking for abnormalities such as switch malfunctions or cable disconnections becomes complex, and existing techniques fail to determine the validity of forwarding entries stored by switches effectively.
Innovation Solution
A server and switch system that stores and generates topology information, learns and maps transfer entries to network route information, allowing for easy detection of abnormalities by comparing switch-stored entries with network route information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual switches are checked for abnormalities as the number of switches increases, then network abnormality detection capability is maintained, but the complexity of tracking data transfer becomes very complicated
Solution Approach 1:
The patent introduces a server as an intermediary device that centralizes the collection and analysis of transfer entries from multiple switches. Instead of manually checking each switch individually, the server automatically gathers transfer entry information from all switches, performs centralized analysis, and identifies abnormalities. This intermediary approach maintains abnormality detection capability while significantly reducing the operational complexity of tracking data transfer across numerous switches.
2Measurement precision
If transfer entries are checked for each switch individually, then abnormality detection is possible, but the process becomes very complicated as network scale increases
Solution Approach 1:
The patent merges the分散ed transfer entry checking process into a centralized operation. The server collects transfer entries from all switches and performs unified analysis, combining multiple individual checking tasks into a single coordinated process. This merging approach maintains measurement precision for transfer entry validation while dramatically improving ease of operation by eliminating the need for manual inspection of each switch separately.
Solution Approach 2:
The server performs automatic collection and analysis of transfer entries without requiring manual intervention for each switch. The system enables self-service by having the server autonomously gather transfer entry information from switches, validate the data, and identify abnormalities automatically, thereby maintaining validation accuracy while greatly simplifying the operational process.
3Measurement precision
If network topology information is collected and analyzed centrally, then transfer entry validity can be determined accurately, but the system requires more complex infrastructure
Solution Approach 1:
The server performs multiple functions including collecting transfer entries from switches, storing topology information, generating route information, analyzing transfer entry validity, and identifying abnormalities. By consolidating these diverse functions into a single multi-functional server, the system achieves accurate transfer entry validity determination while avoiding the need for multiple specialized devices, thereby reducing overall infrastructure complexity.
