Network Device Configuration Version Control With Git Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network configuration management systems lack the ability to efficiently track configuration change history, revert to previous configurations, amend changes, and resolve conflicts, especially in complex network environments with multiple users.
Innovation Solution
Implementing a source control management system, such as Git™, to manage network device configurations, allowing for version control and intelligent configuration management by tracking changes, storing differences between configurations, and providing features like reverting to past configurations and resolving conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized configuration manager is used to manage network configurations, then configuration changes can be controlled and applied, but the system lacks the ability to track configuration change history and revert to previous configurations
Solution Approach 1:
The system performs preliminary actions by automatically saving configuration snapshots before applying changes and maintaining a version history database. This allows the system to have configuration backup and recovery capabilities built-in before problems occur, enabling reversal to previous states without manual intervention.
2Ease of operation
If configuration sessions are allowed to be modified and exited at any time without impacting running configuration, then configuration flexibility is improved, but the ability to track and manage configuration versions is lost
Solution Approach 1:
The system implements feedback mechanisms by automatically recording all configuration session changes in a version history database. Each configuration modification is tracked with metadata including timestamp, user information, and change descriptions. This feedback loop ensures that flexible configuration operations are accompanied by complete version tracking without restricting operational freedom.
3Speed
If configuration changes are applied immediately to the running configuration, then configuration updates take effect quickly, but the ability to review and amend changes before application is reduced
Solution Approach 1:
The system segments the configuration management process into distinct phases: configuration drafting, review, approval, and application. Configuration changes are first created as draft versions that can be reviewed and amended, then approved through a structured process, and finally applied to the running configuration. This segmentation allows both quick application when approved and thorough review before application.
4Productivity
If multiple users can work on network device configurations simultaneously, then configuration collaboration is improved, but conflict resolution becomes difficult
Solution Approach 1:
The system introduces an intermediary configuration management platform that mediates between multiple users and the network device configurations. This intermediary maintains a centralized version history database, tracks all user changes, detects conflicts, and provides automated conflict resolution mechanisms. Users work through the intermediary rather than directly on devices, enabling simultaneous collaboration with automated conflict management.

AI summary
Particular example embodiments described herein can provide for a system, an apparatus, and a method for providing synchronization for a network device operating in a network environment. Operations may include managing a configuration for the network device by a source control management (SCM) engine configured to track changes in the configuration using a source control management system (SCM) database. The operations may also include synchronizing the configuration between the SCM database and a system database of the network device such that their stored representations of configuration information associated with the network device are substantially the same. In particular embodiments, the SCM engine comprises a Git™ element that allows for one or more differences to a configuration session to be committed with a corresponding full textual representation.
