Packet Conversion Device Grouping by Header Attributes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current format conversion techniques for network monitoring and traffic analysis are inflexible and cannot perform varying processing based on the attributes of business operators, as they only process encapsulated packets uniformly and lack the ability to branch processing according to the contents of packet headers.
Innovation Solution
A conversion device and method that analyze input packets, classify them into groups based on header information using set conditions, and generate packets for analysis, allowing for different processing and analysis for each attribute of business operators by providing group identifiers and performing operations like header deletion or transmission destination changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If uniform processing is applied to all encapsulated packets according to encapsulation format, then processing simplicity is maintained, but flexibility to handle different business operator attributes is lost
Solution Approach 1:
The patent segments the uniform processing flow into multiple branch processing paths based on packet header analysis. The grouping unit divides packets into different groups (e.g., business operator groups) based on header information, allowing each group to receive customized processing appropriate to its attributes while maintaining overall system manageability.
Solution Approach 2:
The patent introduces dynamic processing capabilities where the processing applied to packets is not fixed but varies based on real-time analysis of packet header contents. The system dynamically determines which processing branch to execute based on the identified business operator attributes, enabling adaptive handling of different packet types within a unified framework.
2Manufacturing precision
If packet header analysis is performed to enable flexible processing, then processing accuracy is improved, but processing time increases
Solution Approach 1:
The patent performs packet header analysis early in the processing flow, before the main processing operations. The analysis unit extracts and identifies business operator attributes from packet headers in advance, so that subsequent processing can proceed efficiently with pre-determined parameters without repeating analysis operations.
Solution Approach 2:
The patent extracts only the necessary header information required for business operator identification, rather than analyzing entire packets. The analysis unit selectively extracts relevant header fields to determine packet grouping, minimizing processing overhead while maintaining sufficient accuracy for flexible processing decisions.
3Adaptability or versatility
If multiple processing branches are implemented for different packet groups, then processing versatility is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal processing framework where a single conversion device handles multiple processing branches through configurable parameters. The grouping unit and processing execution unit are designed to accommodate different processing types (format conversion, header deletion, destination modification) within a unified architecture, reducing the need for separate specialized systems for each processing branch.

AI summary
A conversion device analyzes an input packet and acquires header information included in the packet. Furthermore, the conversion device classifies packets into one of a plurality of groups on the basis of the acquired header information and set grouping conditions. Subsequently, the conversion device generates packets for analysis on the basis of the processing corresponding to the classified groups.
