Network Device Self-Configuration via POAP Database Query
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The initial provisioning and daily maintenance of large-scale networks with hundreds or thousands of network devices are labor-intensive and error-prone, as they require manual configuration and management by administrators, despite the use of scripts for automation.
Innovation Solution
A method is introduced that uses a Power On Auto Provisioning (POAP) process, where network devices query a configuration database using a unique identifier to retrieve configuration information, applying it to create a configuration file for automatic provisioning and maintenance, simplifying the process and reducing human error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual provisioning and configuration methods are used for network devices, then network administrators can maintain control over configuration decisions, but the process becomes labor-intensive and error-prone
Solution Approach 1:
The network device automatically retrieves its configuration file from the server using its device identifier as a key, without requiring manual administrator intervention. The device self-provisions by querying the configuration database and applying the retrieved configuration, eliminating repetitive manual tasks while maintaining configuration accuracy through automated retrieval.
Solution Approach 2:
A configuration server acts as an intermediary between network administrators and network devices. The server stores configuration files in a database and provides them to devices automatically based on device identifiers, reducing direct administrator involvement while ensuring accurate configuration delivery through a centralized management system.
2Productivity
If scripts are used to automate configuration download, then some repetitive tasks are automated, but critical decisions still require administrator intervention
Solution Approach 1:
Configuration files are prepared and stored in the configuration database in advance, organized by device identifier. When a network device needs configuration, it simply queries the database using its identifier and retrieves the pre-prepared configuration file, eliminating the need for real-time administrator decisions and script execution complexity.
3Adaptability or versatility
If manual configuration management is used for each network device, then administrators can make critical decisions, but the process remains labor-intensive
Solution Approach 1:
Instead of manually configuring each network device individually, the system creates and stores configuration file copies in a centralized database, indexed by device identifier. Each device retrieves its specific configuration copy automatically, reducing provisioning time from minutes per device to seconds per device while maintaining configuration control through centralized storage.
Data Source
AI summary
In accordance with one example embodiment, there is provided a method for accessing a configuration database file corresponding to a network comprising a network device and using a device identifier of the network device as a key to the configuration database file to access a file entry containing configuration information for the network device. The configuration information may include identification of a configuration template file and at least one network parameter. The method may further include applying the at least one network parameter to the template file to create a configuration file and configuring the network device using the configuration file.
