Network Test Instrument Dual Discovery Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network test instruments cannot indicate when a network device is identified through both wireless and wired discovery systems, limiting the information that can be learned about network devices in 802.11 networks, especially in environments with advanced security models that do not use shared secrets.
Innovation Solution
A network test instrument that presents a graphical user interface (GUI) listing network devices discovered via wireless and wired connections, allowing users to select devices and view diagnostic information acquired through both methods, with indicators showing information acquired via both 802.11 and 802.3 connections, enabling cross-link navigation between wireless and wired device details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network test instruments use wireless (802.11) discovery to identify network devices, then device identification capability is improved, but information completeness deteriorates due to encryption limiting access to only layer 1 and layer 2 information
Solution Approach 1:
The patent combines wireless (802.11) discovery and wired (802.3) discovery into a unified system. The graphical user interface merges device listings from both discovery methods, allowing users to view complementary information: wireless provides layer 1-2 data while wired provides layer 3 data, together offering complete device identification and diagnostic information.
Solution Approach 2:
The patent introduces a wired connection as an intermediary method to bypass wireless encryption limitations. By establishing a wired connection to the same network device, the system can retrieve encrypted layer 3 information that cannot be obtained through wireless discovery alone, thus complementing the wireless discovery data.
2Reliability
If network test instruments provide separate listings for wireless and wired device discovery, then discovery methods are maintained, but user understanding of device identification sources deteriorates
Solution Approach 1:
The patent merges separate wireless and wired device listings into a single unified listing in the graphical user interface. Each device entry includes indicators showing which discovery methods identified it, allowing users to understand the sources of device identification without managing separate listings for each discovery method.
Solution Approach 2:
The patent applies local quality by adding specific indicators to device listing entries that show whether the device was identified through wireless discovery, wired discovery, or both methods. This localized information enhancement provides users with clear understanding of identification sources without complicating the overall interface structure.
3Loss of information
If network test instruments display all available diagnostic information for selected devices, then information completeness is improved, but interface complexity deteriorates when handling multiple discovery methods
Solution Approach 1:
The patent merges diagnostic information from wireless and wired discovery methods into a single unified view when a device is selected. Instead of requiring users to switch between separate wireless and wired information displays, the system combines all available diagnostic data in one comprehensive display, reducing interface complexity while maintaining information completeness.
Data Source
AI summary
A method and apparatus (e.g., network test instrument) for presenting network device diagnostic information in which a listing of network devices discovered via a first network connection (e.g., wirelessly—802.11) to a test network is presented in a GUI of a network diagnostic instrument. Acquired network diagnostic information for a network device selected from the listing of network devices is then presented in the GUI wherein the presented network diagnostic information is acquired via the first network connection (e.g., wirelessly—802.11). Indication (and a link thereto) is provided in the GUI indicating network diagnostic information for the selected network device was also acquired via a second network connection to the test network (e.g., via a wired connection—802.3).
