Network Element Rollback Point Control via Update Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent generation of configuration rollback points in network elements leads to increased storage resource consumption, as each configuration change triggers the creation of a new rollback point, impacting the efficiency and performance of configuration updates.
Innovation Solution
A method and apparatus that control the generation of configuration rollback points by using a control identifier in configuration update packets to determine whether to create a rollback point, reducing the number of rollback points and thus minimizing storage resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network element automatically generates a configuration rollback point each time a configuration change occurs, then the configuration reliability is improved and the system can quickly rollback to previous states, but the quantity of configuration rollback points stored increases, leading to increased consumption of storage resources
Solution Approach 1:
The patent introduces a control identifier parameter in configuration update packets that changes the behavior of rollback point generation. When the control identifier indicates to generate a rollback point, the network element creates one; when it indicates not to generate, the network element skips creation. This parameter change allows dynamic control over rollback point generation based on configuration change importance, resolving the contradiction between maintaining reliability and reducing storage consumption.
2Loss of information
If the network element generates a configuration rollback point each time a configuration change occurs, then the configuration status can be tracked comprehensively, but the performance of updating configuration data deteriorates due to increased processing overhead
Solution Approach 1:
The patent extracts the rollback point generation step from the mandatory configuration update process. By making rollback point generation optional through the control identifier, the system separates the essential configuration update function from the optional rollback point creation function. This allows the network element to update configuration data without the overhead of generating rollback points for every change, thereby improving performance while maintaining the ability to track configuration status when needed.
Data Source
AI summary
This application discloses a configuration rollback point control method. According to the method, in a process of updating configuration data of a network element, a configuration update packet carries a control identifier, and the control identifier indicates whether to generate a configuration rollback point. When the control identifier indicates to generate the configuration rollback point, the network element generates the configuration rollback point based on updated configuration data; or when the control identifier indicates not to generate the configuration rollback point, a step of generating the configuration rollback point based on updated configuration data is not performed, to control the configuration rollback point on the network element side. Therefore, the network element does not need to generate the configuration rollback point each time a configuration change occurs, thereby reducing a quantity of configuration rollback points, reducing consumption of storage resources of the network element.
