Multi-Protocol Network Profiling for Firmware-Aware Device Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network management software requires dedicated device profiles for each network device, is cumbersome to update, and supports only a single interface, leading to increased complexity and inconvenience when managing devices with different protocols and firmware versions.
Innovation Solution
A network management method and device that automatically probes network devices to determine access interfaces using multiple protocols, generating device configurations without the need for manual profile creation or updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated device profiles are created for each network device, then device management capability is improved, but device complexity and maintenance burden increase
Solution Approach 1:
The network management device automatically probes network devices to obtain model names and firmware versions, then automatically queries or generates corresponding device profiles. This self-service mechanism eliminates manual profile creation and updates, reducing management complexity while maintaining comprehensive device support.
Solution Approach 2:
Device profiles are pre-stored in a database according to model names and firmware versions. When a network device is added, the system performs preliminary matching and profile retrieval before actual management operations, avoiding the need for on-demand profile creation and reducing operational complexity.
2Device complexity
If a single network management interface is used, then system simplicity is maintained, but adaptability to different network device protocols is reduced
Solution Approach 1:
The network management device is designed to support multiple network protocols (SNMP, NETCONF, RESTful, and manufacturer-defined proprietary protocols) through a single unified interface. The system automatically detects and adapts to the appropriate protocol for each network device, providing universal compatibility without requiring multiple separate management systems.
3Manufacturing precision
If manual profile updates are performed for device firmware changes, then management precision is maintained, but time consumption and operational burden increase
Solution Approach 1:
The system continuously monitors firmware version changes on network devices through automatic probing. When a firmware update is detected, the system automatically queries the updated device profile from the database and applies it to the network device, ensuring configuration accuracy is maintained without manual intervention.
Solution Approach 2:
The automatic profile update mechanism performs self-service by detecting firmware changes, retrieving updated profiles, and applying configurations without requiring manual operations. This eliminates time-consuming manual updates while maintaining precise configuration management.

AI summary
A network management method running on a network management device (200) is used to determine a device configuration of a network device (120-122) . The network management method includes obtaining a model name and a firmware version of the network device according to a plurality of network protocols (A-C) ; obtaining or generating a device profile according to the model name and the firmware version; and generating or updating the device configuration of the network device according to the device profile. The step of generating the device profile according to the model name and the firmware version further comprises determining at least one probing control item (F1-F8) of the network device according to the device profile; and probing an access interface of the at least one probing control item according to the plurality of network protocols respectively to update the device profile.
