VPN Exit IP Switching for Data Transfer During IP Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
VPN connections can be inefficient when host devices block communication from assigned exit IP addresses, leading to resource wastage and disrupted data transfer due to the need to maintain established connections without data transfer or re-establish new connections.
Innovation Solution
A VPN server dynamically assigns a new exit IP address from a secondary server and modifies DNS settings to route data through itself, ensuring continuous data transfer by bypassing blocked IP addresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the VPN server maintains an established VPN connection with the user device, then connection stability is improved, but data transfer reliability deteriorates when the exit IP address is blocked
Solution Approach 1:
The VPN server dynamically switches between primary and secondary exit IP addresses based on block detection. When the primary IP is blocked, the system transitions to using the secondary IP without terminating the VPN connection, maintaining connection stability while adapting to changing network conditions to preserve data transfer reliability
Solution Approach 2:
The system introduces a secondary exit IP address as an intermediary resource. When the primary exit IP is blocked, the secondary IP serves as a mediator to bypass the block and restore data transfer functionality while keeping the original VPN connection intact
2Reliability
If the VPN server switches to a new exit IP address from a secondary server, then data transfer reliability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the IP address management function from the core VPN connection logic. The secondary server with its pool of exit IP addresses operates as a separate, independent system that the VPN server can tap into when needed, adding minimal complexity to the main system while providing robust failover capability
Solution Approach 2:
The secondary server acts as an intermediary that handles IP address management and switching. This mediator absorbs the complexity of managing multiple IP addresses and block detection logic, allowing the primary VPN server to remain relatively simple while still achieving high data transfer reliability
3Productivity
If the VPN server uses a secondary exit IP address to bypass blocks, then productivity is improved, but loss of time increases due to DNS modification
Solution Approach 1:
The system performs preliminary actions by pre-configuring the secondary exit IP address and establishing the secondary server relationship before blocks occur. When blocking is detected, the switch to the secondary IP can happen rapidly because the infrastructure is already in place, minimizing the time loss associated with DNS modifications and configuration changes
