Networking Device Testing System With Integrated Connector Pairs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing testing systems for networking devices, such as switch devices, require time-consuming and error-prone cabling setups for performance and quality testing, which exceeds the duration of the testing itself.
Innovation Solution
A testing device with a chassis featuring pairs of connectors that can be quickly and accurately connected to networking devices, allowing bi-directional traffic flow and integration with a load generator, reducing setup time and errors by using moveable and configurable connector couplings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cabling methods are used to connect pairs of ports for snake testing, then the testing can be performed, but the setup time becomes much longer than the actual testing duration
Solution Approach 1:
A testing device with integrated connector pairs acts as an intermediary between the networking device and the load generator. The device includes a plurality of first connectors that connect to networking device ports and a plurality of second connectors that connect to the load generator, with internal cabling that pre-establishes the required port pairings. This eliminates the need for manual cable pairing during setup.
Solution Approach 2:
The connector pairs and internal cabling are pre-configured within the testing device before use. The internal cabling permanently connects specific first connectors to each other in predetermined pairs, so that when the device is connected to the networking device, the port pairings are already established and ready for immediate testing.
2Reliability
If manual cabling preparation is performed for each port pair, then the correct connections can be established, but human errors increase during the process
Solution Approach 1:
The testing device merges multiple connectors and their interconnections into a single integrated unit. Instead of separately managing individual cables between port pairs, all connectors are housed together with internal cabling that automatically establishes the correct connections, reducing the number of separate connection operations required.
Solution Approach 2:
The testing device serves as an intermediary that pre-establishes accurate connections internally, eliminating the need for manual cable pairing operations and the associated human errors. The device abstracts away the complexity of port pairing from the user.
3Reliability
If multiple individual cables are used to connect port pairs, then the testing configuration can be achieved, but the number of cables and connections increases significantly
Solution Approach 1:
Multiple individual cable connections are merged into a single integrated testing device. The internal cabling structure combines what would otherwise be multiple separate cable operations into one unified device that connects to the networking device through a single physical interface.
Solution Approach 2:
The testing device segments the complex cabling task into a manageable integrated unit. Instead of dealing with numerous individual cables, the device presents a simplified interface while maintaining the functional equivalence of multiple port pairings through its internal structure.
