SNMP Agent MIB Generation via OIDInfo Processor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of SNMP agents is complex and time-consuming due to the need for different MIB structures for various devices, requiring frequent recompilation and modification when device characteristics change, adding, or deleting management items.
Innovation Solution
A network management system that generates a management information base (MIB) file and object identifier information (OIDInfo) file in real-time, allowing for dynamic management of communication devices using SNMP, with an SNMP agent comprising an OIDInfo processor for communication between the SNMP agent and application programs, reducing the need for frequent recompilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different MIB structures are created for various devices, then device-specific management requirements are met, but development complexity and time increase significantly
Solution Approach 1:
The MIB structure is segmented into device-specific portions and common portions. The extractor separates MIB objects into these distinct segments, allowing device-specific customization without affecting the overall system complexity. Each device type can have its own MIB structure while sharing common management functions.
Solution Approach 2:
The extractor acts as an intermediary that automatically generates MIB files from header files. This intermediary component handles the complexity of MIB structure creation, transforming device-specific requirements into standardized MIB formats without requiring manual intervention for each device type.
2Manufacturing precision
If MIB files are modified to accommodate changing device characteristics, then device management accuracy improves, but recompilation frequency and time consumption increase
Solution Approach 1:
Header files containing device-specific management information are prepared in advance during the development phase. The extractor uses these pre-prepared header files to automatically generate MIB files, eliminating the need for manual MIB modification and recompilation when device characteristics change.
Solution Approach 2:
The system enables self-service through automatic MIB file generation. When device characteristics change, the extractor automatically updates MIB files by processing modified header files, without requiring manual intervention or full recompilation of the SNMP agent.
3Manufacturing precision
If manual MIB file generation is performed for each device, then MIB structure accuracy improves, but productivity and efficiency decrease
Solution Approach 1:
The extractor serves as an automatic intermediary that generates MIB files from header files, ensuring structural accuracy while dramatically improving productivity. This automated process eliminates manual MIB file creation for each device while maintaining consistent and accurate MIB structures through systematic processing.
Solution Approach 2:
The system uses template-based copying where standard MIB structures are replicated and adapted for different device types. The extractor copies and modifies proven MIB structures based on device-specific header file information, ensuring accuracy through template consistency while improving productivity through reuse.

AI summary
An apparatus and method is provided for managing a communication device using Simple Network Management Protocol (SNMP). When a developer creates an SNMP interface header file through an application program at a compile time, an extractor generates a management information base (MIB) file and object identifier information (OIDInfo) on the basis of the interface header file. When a manager makes an SNMP request at a run time, an agent sends the OIDInfo included in the SNMP request message to an OIDInfo processor. The OIDInfo processor refers to an OIDInfo memory and delivers general message service (GMS) information to the agent. A GMS request/response process between the agent and the application program is then performed on the basis of the GMS information.
