Protocol Tester Filter Configuration via Frame Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Configuring filters for protocol testers to extract specific data stream frames, such as RPAC-UL messages, requires extensive expert knowledge, as users must identify the relevant protocol and protocol stack, making it difficult for unskilled users to filter data streams effectively.
Innovation Solution
A method that decodes and displays frames in an overview, allowing users to search and highlight desired content, derive a filter rule from the highlighted frame, and apply it to all frames, eliminating the need for internal protocol configuration knowledge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional filter configuration methods are used, then filtering functionality is achieved, but user expertise is required and configuration complexity increases
Solution Approach 1:
The system performs self-analysis by automatically examining the captured data stream, identifying protocol structures, and generating filter configuration recommendations without requiring user knowledge of internal protocol details. The filter configuration is derived automatically from the data itself rather than from predefined protocol specifications.
Solution Approach 2:
An intermediary processing layer is introduced between the raw data stream and the filter configuration. This layer automatically analyzes the data, extracts protocol information, and translates it into filter settings, shielding the user from protocol complexity while maintaining filtering functionality.
2Measurement precision
If detailed protocol knowledge is required for filter configuration, then precise filtering is achieved, but user training time and operational difficulty increase
Solution Approach 1:
The system automatically performs the analysis and configuration tasks that would otherwise require expert knowledge. By examining the data stream itself and deriving filter parameters from actual protocol structures, the system achieves precise filtering without requiring users to understand protocol details.
Solution Approach 2:
The system performs preliminary analysis of the data stream to automatically generate filter configuration recommendations before the user needs to apply filters. This preliminary action includes identifying protocol structures, extracting relevant parameters, and preparing filter settings in advance.

AI summary
A method of configuring a filter for a data stream organized in frames in a protocol tester that is simple without requiring any knowledge of an internal protocol configuration provides the frames partially decoded in an overview display. A user searches the frames for a desired content and selects one of the frames having the desired content. The selected frame is displayed in a fully decoded view. A filter rule is derived from the desired content for configuring the filter. The filter rule may be further defined by modifying parameters from the fully decoded view of the selected frame. The configured filter is applied to all the frames to produce a set of filtered frames.
