Private Network Mirroring for Configuration Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing and maintaining consistency of network configurations across multiple private networks in different geographical or logical areas is challenging, leading to potential failures and increased management overhead, especially in disaster recovery scenarios where manual updates are time-consuming and error-prone.
Innovation Solution
Implementing a method for private network mirroring that automatically propagates configuration changes from a designated 'master' network to 'mirror' networks, using an event bus and dependency model to ensure real-time updates and reduce manual intervention, allowing for efficient disaster recovery and failover management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual updates are used to maintain network configurations across multiple private networks, then flexibility in configuration management is maintained, but management overhead increases and errors are more likely to occur
Solution Approach 1:
The system enables automatic self-updating of network configurations through the following mechanism: when a configuration change is detected in the master private network, the system automatically propagates the change to mirror networks via the event bus and dependency model, eliminating the need for manual intervention and reducing management overhead while maintaining consistency across all networks
Solution Approach 2:
The system implements real-time monitoring and automatic propagation of configuration changes through the event bus mechanism. When configuration changes occur in the master network, the system detects these changes and automatically propagates them to mirror networks, ensuring continuous consistency without requiring manual verification or updates
2Reliability
If manual updates are performed for disaster recovery scenarios, then configuration accuracy can be maintained, but time consumption increases
Solution Approach 1:
The system performs preliminary actions by maintaining real-time mirrors of network configurations across different geographical areas. When a failure occurs, the mirrored configurations are already ready and can be immediately activated, eliminating the need for manual updates during disaster recovery scenarios and significantly reducing downtime
Solution Approach 2:
The system ensures continuous operation by automatically propagating configuration changes in real-time to mirror networks. This continuous synchronization ensures that when a failure occurs, the mirrored networks are already up-to-date and can immediately take over, eliminating interruptions and reducing recovery time
3Reliability
If real-time configuration propagation is implemented, then configuration consistency is improved, but system complexity increases
Solution Approach 1:
The system introduces an event bus as an intermediary component that facilitates real-time configuration propagation. The event bus receives configuration change events from the master network and automatically distributes them to mirror networks through the dependency model, achieving real-time consistency without requiring complex direct connections between all networks

AI summary
Techniques for private network mirroring are described. Users can select one or more existing private networks to be mirrored in the same or different network area. Any network configuration changes made in the selected private network (e.g., "master" private network) can be propagated automatically to the mirror private network. This enables users to utilize resources in another network area for disaster recovery, ensuring that the network configuration of the mirror private network is consistent with the master private network through real-time updates. Additionally, users managing infrastructure that includes multiple private networks can select one master private network and propagate configuration changes to other private networks, reducing management overhead incurred by these multi-private network installations.
