Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users connect to multiple VPN concentrators, then network coverage and accessibility are improved, but network performance consistency deteriorates due to varying latency, throughput, and packet loss
Solution Approach 1:
The system continuously monitors network performance metrics (latency, throughput, packet loss) for each VPN concentrator and uses this feedback to dynamically update performance data. This real-time feedback mechanism enables the system to adapt to changing network conditions and guide users to optimal concentrators, resolving the contradiction between wide coverage and consistent performance.
Solution Approach 2:
The VPN concentrator performance data is dynamically updated and refreshed to reflect current network conditions. The system transitions from static concentrator selection to dynamic, condition-based selection, allowing users to be directed to the best available concentrator at any given moment, thereby maintaining performance consistency across multiple access points.
2Ease of operation
If users manually select VPN concentrators, then connection establishment is simplified, but network performance optimization deteriorates due to lack of knowledge about concentrator quality
Solution Approach 1:
The system introduces an intermediary mechanism that automatically evaluates VPN concentrator performance and provides recommendations to users. This intermediary layer handles the complexity of performance assessment while maintaining simple user interaction, allowing users to benefit from optimized performance without needing to manually analyze concentrator quality metrics.
Solution Approach 2:
The system enables automatic selection and optimization of VPN concentrators based on real-time performance data. The network infrastructure serves itself by automatically identifying and directing traffic to optimal concentrators without requiring user intervention or knowledge, thereby maintaining ease of operation while achieving performance optimization.
3Productivity
If VPN concentrator performance data is continuously updated, then network performance optimization is improved, but data processing and system complexity increase
Solution Approach 1:
The system updates VPN concentrator performance data at controlled intervals rather than continuously, using partial updates based on significant changes in network conditions. This approach maintains performance optimization benefits while reducing unnecessary data processing and system complexity associated with constant monitoring and updating.
Data Source
AI summary
A method, computer system, and computer program product are provided for a multi-route virtual private network. A virtual private network (VPN) concentrator generates network performance data indicating network conditions between the VPN concentrator and a server. The VPN concentrator receives additional network performance data indicating network conditions between at least one additional VPN concentrator and the server. The network performance data and the additional network performance data are provided to a client. In response to the client analyzing the network performance data and the additional network performance data to determine that a VPN connection to the server via the VPN concentrator satisfies one or more policy criteria, the VPN connection is established between the server and the client via the VPN concentrator.
