Switchboard VPN System for Dynamic Interface Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VPN systems are complex to set up and manage, require a central server for authentication, and struggle with dynamic interface switching and optimizing performance across multiple connections, especially in insecure public networks.
Innovation Solution
A switchboard-based VPN system using open standards like XMPP and Jingle protocols for peer-to-peer connections, with a directory service for dynamic interface management and encryption, allowing for adaptive routing and optimization across multiple interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a classic VPN system is used with centralized server authentication, then security is improved, but device complexity and ease of operation deteriorate due to required administrator intervention for key management and firewall configuration
Solution Approach 1:
The system enables automatic peer-to-peer VPN connections where clients autonomously establish encrypted tunnels using pre-configured public keys and session key exchange, eliminating the need for centralized authentication servers and administrator intervention for key management
Solution Approach 2:
The centralized authentication server component is extracted and removed from the system. Instead of requiring a central authority, the patent implements direct peer-to-peer authentication using distributed public key infrastructure, simplifying the system architecture
2Adaptability or versatility
If multiple network interfaces are available for VPN connection, then adaptability is improved, but ease of operation deteriorates due to complexity of switching between interfaces and optimizing performance
Solution Approach 1:
The system dynamically monitors the status and performance of multiple network interfaces (WiFi, Ethernet, cellular) and automatically adapts VPN connections by switching interfaces based on real-time conditions such as connectivity status, signal strength, and latency, eliminating manual interface management
Solution Approach 2:
The system continuously monitors network interface performance metrics and uses this feedback to automatically optimize VPN connection routing, selecting the best available interface for maintaining secure connections without user intervention

AI summary
Systems and methods to provide improved secure, high speed networking between two or more computers is disclosed. The invention provides a robust and flexible means to readily establish a secure connection between two or more computers using insecure public or private network connections, while eliminating most of the difficulties and issues a user typically experiences with varying virtual private networks (“VPN”) and firewall configurations. The inventive system can be adapted to route traffic across multiple network connections based on a variety of criteria, including without limitation, the importance of any given data, the cost of each means of connection, and/or the performance of each possible means of connecting to the client system.
