Networking Subsystem Port Mapping for Legacy Switch Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for connecting older generation switch devices to newer generation networking subsystems using optical modules are costly and power-consuming, while passive cables like DACs are not suitable due to lane and speed mismatches.
Innovation Solution
A port configuration engine in the networking subsystem automatically detects and configures a single logical port to transmit data between multiple physical ports, enabling connection of older generation switch devices to newer generation networking subsystems using passive cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optical modules are used to connect older generation switch devices to newer generation networking subsystems, then connection compatibility is achieved, but cost and power consumption increase significantly
Solution Approach 1:
The patent changes the connection parameters by using passive cables instead of active optical modules, fundamentally altering the transmission medium from electrical to optical domain. This parameter change enables compatibility between different generation devices while eliminating power consumption issues associated with optical modules
Solution Approach 2:
The patent introduces an intermediary conversion system that includes a first network device with optical interface, a second network device with electrical interface, and a passive cable connecting them. This intermediary approach enables connection between incompatible devices without requiring expensive and power-consuming optical modules on both ends
2Reliability
If passive cables like DACs are used to connect older generation switch devices to newer generation networking subsystems, then cost is reduced, but connection fails due to lane and speed mismatches
Solution Approach 1:
The patent segments the connection system into distinct functional parts: an optical interface device, an electrical interface device, and a passive cable. This segmentation allows each component to operate at its optimal interface type, with the conversion handled by dedicated network devices, thereby achieving reliable connection despite lane and speed differences
Solution Approach 2:
The patent uses network devices with appropriate interfaces as intermediaries to bridge the gap between optical and electrical connections. These intermediary devices perform the necessary signal conversion and lane mapping, enabling successful connection without requiring direct compatibility between the switch and networking subsystem
3Reliability
If manual configuration is performed to establish connections between physical ports, then connection accuracy is improved, but time consumption and operational complexity increase
Solution Approach 1:
The patent implements self-service automation where the system automatically detects cable connections, identifies connected physical ports, and configures logical port mappings without manual intervention. This self-configuration capability maintains connection accuracy while dramatically reducing configuration time and operational complexity
Solution Approach 2:
The patent employs feedback mechanisms where the system continuously monitors cable connection status and automatically adjusts logical port configurations in response to detected changes. This feedback-driven automation ensures accurate connections while eliminating manual configuration steps, achieving both reliability and efficiency

AI summary
A networking subsystem/switch device connection configuration system includes a switch device having a switch physical port, and an endpoint device including a networking subsystem having a plurality of networking physical ports. The networking subsystem detects connection of respective cable connectors to each of the plurality of networking physical ports. If the networking subsystem determines that each of the respective cable connectors connected to the plurality of networking physical ports are included on the same cable, it configures a single networking logical port to transmit data between each of the plurality of networking physical ports and the switch physical port.
