RADIUS Client Auto-Setup via LLDP in Shared Network Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Setting up a RADIUS client in a communication system requires manual input of complex configuration information, which is cumbersome and inefficient.
Innovation Solution
A communication system where a first network device transmits identification information and a secret key to a second network device, enabling the second device to automatically operate as a RADIUS client without user intervention, using protocols like LLDP for efficient information transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual configuration of RADIUS client settings is used, then configuration accuracy can be ensured, but setup time and operational complexity increase significantly
Solution Approach 1:
The patent enables RADIUS client settings to be automatically configured through self-service mechanisms. The system automatically discovers RADIUS servers, retrieves authentication parameters, and configures client settings without requiring manual intervention. This eliminates the time-consuming manual configuration process while maintaining configuration accuracy through automated validation.
Solution Approach 2:
The patent implements preliminary action by pre-configuring RADIUS server information and authentication parameters in advance. The system performs automatic discovery and parameter retrieval before actual RADIUS client operation is needed, so that when deployment occurs, the configuration is already prepared and can be applied immediately without manual setup.
2Productivity
If automated RADIUS client setup is implemented, then setup time is reduced, but configuration security may be compromised
Solution Approach 1:
The patent introduces an intermediary mechanism in the form of secure parameter retrieval and validation processes. The system acts as an intermediary between the automatic configuration process and the RADIUS server, implementing security checks, authentication verification, and encrypted parameter transmission. This intermediary layer ensures that automated setup maintains configuration security by validating all parameters before application.
3Manufacturing precision
If complex RADIUS configuration parameters are manually entered, then configuration precision can be maintained, but operational complexity increases
Solution Approach 1:
The patent extracts complex RADIUS configuration parameters from the manual configuration process. Instead of requiring users to manually enter and manage multiple complex parameters (authentication keys, server addresses, port numbers, etc.), the system automatically extracts these parameters from the RADIUS server through automated discovery and retrieval processes, leaving only simple activation actions for the user.
Data Source
AI summary
A communication system includes a first network device including a RADIUS server configured to determine whether to authenticate a network communication of a terminal, or a first RADIUS client corresponding to a RADIUS server and storing identification information identifying the RADIUS server and a secret key, and a second network device directly connected to the first network device in the same network segment as the first network device. The first network device includes a first processor and a first memory device configured to store a first program, the first program being executed by the first processor to cause the first processor to transmit the identification information and the secret key to the second network device in a first time period.
