Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network testing systems require IP addresses for devices, leading to increased costs and scalability issues, especially when dealing with large numbers of unaddressed test devices in distributed networks.
Innovation Solution
A method and system for network testing that utilize unaddressed test devices by inspecting and recognizing packets with embedded identification patterns, allowing communication and remote control without assigning IP addresses, using authentication patterns to identify and communicate with unaddressed devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If IP addresses are assigned to all test devices in a distributed network, then network communication and control are enabled, but network cost and complexity increase significantly
Solution Approach 1:
The patent introduces an intermediary mechanism where control devices send commands embedded within data packets that pass through unaddressed test devices. The test devices inspect packets for embedded authentication patterns and commands, allowing control without requiring traditional IP addressing. This intermediary command-embedding approach enables communication while avoiding the complexity of IP address management.
2Quantity of substance
If IP addresses are assigned to minimize total addresses on network, then cost is reduced, but communication capability with test devices is limited
Solution Approach 1:
The patent extracts the communication capability from the traditional IP addressing requirement. Test devices are taken out of the conventional addressing scheme and instead communicate through packet inspection of embedded authentication patterns. This extraction allows minimal or zero IP addresses to be assigned while maintaining full communication capability through alternative identification mechanisms.
3Adaptability or versatility
If unaddressed test devices are used to reduce IP address requirements, then scalability and cost improve, but device identification and control become difficult
Solution Approach 1:
The patent uses authentication patterns as distinctive identifiers for unaddressed test devices, analogous to color changes for identification. Each test device or device type can be identified by unique authentication patterns embedded in packets, enabling easy detection and identification without traditional addressing. This pattern-based identification scales effortlessly across large numbers of devices.

AI summary
A method of network testing relies on communication with an unaddressed test device (104). The method includes collection of network addresses from packets passing through the test device and a discovery procedure. The collected addresses are provided to a remote control device (150), and used for communication between the test device (104) and the control device (150).
