Parallel VPN Tunneling for Continuous Server Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VPN systems inefficiently manage VPN connections, leading to resource wastage when optimal servers become unavailable or overloaded, requiring frequent connection reestablishment.
Innovation Solution
Establishing parallel VPN connections with multiple servers and dynamically determining a default and optimal server for continuous, efficient VPN service provision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single VPN connection is established with one server, then connection simplicity is maintained, but service continuity deteriorates when the server becomes unavailable or overloaded
Solution Approach 1:
The system segments the VPN connection by establishing multiple parallel connections to different VPN servers instead of relying on a single connection. This segmentation allows the system to distribute traffic and maintain service continuity by switching between segments (connections) when one becomes unavailable or overloaded.
Solution Approach 2:
The system implements dynamic connection management by continuously monitoring the status and performance of multiple VPN connections, automatically determining which connection is optimal at any given time, and dynamically switching between connections based on real-time conditions such as server availability and load.
2Reliability
If multiple VPN connections are established with multiple servers, then service continuity is improved, but resource consumption increases
Solution Approach 1:
The system applies partial action by maintaining multiple VPN connections in parallel but only actively using the optimal one for data transmission at any given time. The other connections remain as standby resources, consuming minimal energy while providing backup capacity, thus balancing reliability improvement with resource conservation.
Solution Approach 2:
The system implements self-service through automated connection monitoring and dynamic selection algorithms that independently determine the optimal VPN connection without requiring manual intervention. This automation reduces the computational overhead and energy consumption associated with managing multiple connections.
3Adaptability or versatility
If frequent connection reestablishment occurs when servers become unavailable, then adaptability is improved, but connection stability deteriorates
Solution Approach 1:
The system performs preliminary action by pre-establishing multiple VPN connections to different servers before any single connection becomes unavailable. This advance preparation ensures that alternative connections are already in place and ready for immediate use, eliminating the need for frequent connection reestablishment and maintaining stability while adapting to server availability changes.
