Hierarchical Context Area Network for VPN Infrastructure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual private network (VPN) systems are inefficient, inflexible, and resource-intensive, with sub-optimal data transport pathways and limited control over resource utilization, leading to slow communication speeds and high maintenance costs.
Innovation Solution
Implementing a hierarchical-context area network as a VPN infrastructure system, which uses a hierarchy of context areas with dynamic ad-hoc paths for data routing, reuses IP addresses, and controls traffic prioritization, allowing for dynamic reconfiguration of the point of egress to improve communication speed and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional VPN systems are used, then privacy and security are provided, but communication speed is slow and resource utilization is high
Solution Approach 1:
The patent segments the network into hierarchical context areas (local, regional, national, international) with multiple context levels. Each context area network is allocated specific IP address ranges and can operate semi-independently, allowing data to be routed through optimized local paths rather than traversing the entire global VPN infrastructure, thereby improving speed while reducing overall resource utilization.
Solution Approach 2:
The system dynamically reconfigures the point of egress and routing paths based on current network conditions, user location, and traffic patterns. Context area networks can be dynamically created, modified, or merged, and IP addresses are dynamically allocated and reused across different context levels, enabling adaptive optimization of communication speed and resource usage.
2Adaptability or versatility
If traditional VPN systems are used, then basic connectivity is provided, but system flexibility and adaptability are limited
Solution Approach 1:
The patent implements a nested hierarchical structure where context area networks at different levels (local, regional, national, international) contain and are contained by networks at adjacent levels. Each context level nests multiple context areas, creating a scalable framework that can adapt to various deployment scenarios without requiring complete system redesign, thus improving flexibility while managing complexity through structured organization.
Solution Approach 2:
The system design allows context area networks to serve multiple functions simultaneously - providing privacy, enabling fast local communication, supporting dynamic reconfiguration, and facilitating scalable deployment. The same hierarchical framework accommodates different VPN use cases and can be implemented across diverse network infrastructures, enhancing versatility without proportionally increasing complexity.
3Loss of substance
If IP addresses are not reused across context areas, then network management is simplified, but resource efficiency is reduced
Solution Approach 1:
The patent implements local quality by allowing IP address reuse within specific context areas and levels while maintaining global uniqueness through hierarchical structuring. Each context area network is allocated specific IP ranges that can be reused at different context levels, and the system locally manages address translation and routing information, enabling efficient IP utilization without overwhelming global management complexity.

AI summary
A hierarchical-context area network includes a first, level-one, context area network, a second, level-one, context area network, and a third, level-two, context area network, wherein the first context area network is allocated a first shared IP address in a first range, the first context area network includes a first VPN server having a second IP address in the first range, the second context area network is allocated a second shared IP address in a second range, the second context area network includes a second VPN server having a fourth IP address in the second range, communication between the first VPN server and the second VPN server is unavailable via context area networks other than via a data link layer network established between the first VPN server and the second VPN server via the third context area network.
