Network Port Bandwidth Auto-Configuration via Cable ID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a mismatch between the bandwidth provided by network cables and the configuration of network ports, leading to wasted throughput capabilities, as network components often do not utilize all available bandwidth or operate within the desired data transfer rates.
Innovation Solution
A management resource dynamically configures network components to match the desired bandwidth with the available bandwidth provided by cables, ensuring optimal data transfer speeds by interrogating cables for identifying information and adjusting port settings accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network ports are configured with fixed bandwidth settings, then device complexity is reduced and ease of operation is improved, but throughput capability is wasted and productivity decreases
Solution Approach 1:
The network port automatically determines its own optimal bandwidth configuration by reading cable identifying information and self-configuring without external intervention. The management resource enables this self-service capability by providing the infrastructure for automatic bandwidth detection and configuration, eliminating the need for manual port setup while maximizing throughput capability.
Solution Approach 2:
The system dynamically changes the bandwidth parameter of network ports based on the actual cable capabilities detected through identifying information. Instead of fixed configurations, the port bandwidth parameter is adjusted to match the cable's maximum bandwidth capability, optimizing data transfer speed while adapting to different connection scenarios.
2Adaptability or versatility
If manual configuration is used for network ports, then ease of operation is improved, but adaptability to different cable capabilities deteriorates and loss of information about optimal settings increases
Solution Approach 1:
The network port automatically adapts to different cable capabilities by reading identifying information embedded in the cable and self-configuring the appropriate bandwidth settings. This eliminates the need for users to manually research and configure optimal settings for different cable types, providing both adaptability and ease of operation simultaneously.
Solution Approach 2:
The system uses feedback from cable identifying information to automatically adjust port configuration. The management resource reads cable identifiers, determines maximum bandwidth capabilities, and feeds this information back to configure the network port appropriately, creating a closed-loop system that adapts to actual cable capabilities without user intervention.
3Reliability
If network components operate without dynamic configuration, then device complexity is reduced, but reliability of communication and productivity deteriorate due to bandwidth mismatches
Solution Approach 1:
The system performs preliminary configuration actions by reading cable identifying information and setting optimal bandwidth parameters before data transfer begins. This preliminary setup ensures reliable communication from the start by matching port capabilities to cable capabilities, preventing communication failures that would occur with mismatched configurations.
Solution Approach 2:
The network port automatically performs the reliability-critical task of bandwidth matching without requiring complex external management systems. By enabling self-service configuration based on cable identifiers, the system achieves high communication reliability while keeping the overall device complexity manageable through automated rather than manual processes.

AI summary
A network switching environment includes a network switch coupled to a port extension module by one or more network cables, and a management resource coupled to the switch and the port extension module. The configurations of the network switch and the port extension module may be dynamically controlled by a management resource to adjust to changes in the maximum bandwidth provided by the one or more network cables. The management resource may implement the network switch and port extension module configurations according to a predetermined target configuration and the connection configuration of the network switch and the port extension module.
