Dynamic MIB Loading for Network Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing network devices require lengthy and complex processes to generate new Management Information Bases (MIBs) due to under-lapping issues, where management information is not consistently available across different interfaces, leading to syntax conversion complications and time-consuming software upgrades.
Innovation Solution
A method for dynamically loading MIBs on managed network devices, which includes identifying missing network management objects, creating a policy file to extract values from existing management interfaces, and populating the MIB with these values, allowing for runtime loading without OS upgrades, thus simplifying the process and reducing the need for extensive design and development cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If new MIBs are generated through conventional methods to provide management information to managing network devices, then the management information can be obtained, but the process is complex and time-consuming, requiring vendor software upgrades and lengthy design cycles
Solution Approach 1:
The patent creates a copy of the management information interface by generating a MIB file that mirrors the structure and data of an existing management interface (such as XML, JSON, or HTTP-based interfaces). This copied MIB structure allows managing network devices to query management information through standard SNMP protocols without requiring vendor-specific software upgrades or lengthy design cycles.
2Loss of information
If management information is extracted from existing management interfaces, then the information can be obtained, but syntax conversion is complicated and requires user availability for extraction
Solution Approach 1:
The patent introduces a MIB file as an intermediary layer between the existing management interface and the managing network device. The MIB file translates and standardizes the management information syntax, allowing SNMP-based managing devices to query information without direct complex syntax conversion from other interface formats. This intermediary structure automates the extraction and standardization process.
3Adaptability or versatility
If MIBs are updated through vendor software upgrades, then new management objects are supported, but frequent upgrades are required and the process is extensive
Solution Approach 1:
The patent enables dynamic updates of MIB files on managed network devices without requiring vendor software upgrades. The MIB file can be independently generated, modified, and loaded to support new management objects as needed, making the system adaptable to changing requirements without extensive upgrade processes.

AI summary
In one embodiment, a Management Information Base (MIB) is dynamically loaded on a managed network device that is managed by a managing network device using a management application. Initially, one or more network management objects are identified. The identified one or more network management objects are then included in the MIB. Thereafter, a policy file to be associated with the MIB is defined. Consequently, the MIB is loaded on the managed network device along with the associated policy file.
