Solution Overview

Problem

Existing virtual private network (VPN) systems are inefficient, inflexible, and resource-intensive, with limited control over data transport pathways, leading to sub-optimal performance and high maintenance costs.

Innovation Solution

Implementing a hierarchical-context area network as a VPN infrastructure system, which includes a hierarchy of context areas with multiple VPN servers and a dynamic ad-hoc path routing mechanism, allowing for efficient routing based on account type, geographic location, and organizational structure.

1Productivity

If a traditional VPN system is used, then basic privacy protection is provided, but the system is inefficient and inflexible with high maintenance costs

Engineering Contradiction:

Improvecommunication speedVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the VPN infrastructure into a hierarchical structure with multiple context levels (first VPNI context level, second VPNI context level, etc.), where each level contains multiple context areas with dedicated VPN servers. This segmentation allows for distributed processing and routing decisions, improving communication speed while maintaining manageable complexity through modular organization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a hierarchical dimension to the VPN architecture by organizing context areas across multiple VPNI context levels. This dimensional expansion enables more sophisticated routing control policies that can operate at different hierarchical levels, improving system efficiency and flexibility without proportionally increasing operational complexity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If multiple VPN servers are deployed, then routing control and traffic prioritization are improved, but resource utilization increases

Engineering Contradiction:

Improverouting controlVSAvoidresource utilization

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic routing control policies that can adaptively select egress points based on real-time conditions such as account type, geographic location, and server load. This dynamic approach allows the system to efficiently utilize available VPN server resources without requiring excessive redundant infrastructure, balancing routing control capabilities with resource consumption.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent assigns different routing control policies and service characteristics to different context areas and VPN servers within the hierarchy. Each context area can have optimized routing rules tailored to local requirements, enabling efficient resource utilization while providing differentiated routing control for various user types and traffic patterns.

Inventive Principle:

Principle #3Local quality

3Productivity

If a hierarchical context area network is implemented, then traffic prioritization and throughput are improved, but the device complexity increases

Engineering Contradiction:

Improveend-to-end throughputVSAvoidnetwork infrastructure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the network into hierarchical context levels and context areas, with each segment having dedicated VPN servers and routing policies. This segmentation enables parallel processing of routing decisions at different hierarchical levels, improving end-to-end throughput while keeping individual segment complexity manageable through standardized interfaces and protocols.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent designs the hierarchical context area network with universal routing control policies that can operate across multiple context levels and serve different user types (limited-tier, basic-tier, premium-tier, enterprise-tier). This multi-functionality allows a single hierarchical framework to handle diverse traffic prioritization requirements, improving throughput without proportionally increasing infrastructure complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A hierarchical-context area network includes a first virtual private network infrastructure context area network for a first virtual private network infrastructure context area in a first virtual private network infrastructure context level that includes a first virtual private network server, a second virtual private network infrastructure context area network for a second virtual private network infrastructure context area in the second virtual private network infrastructure context level that includes a second virtual private network server, wherein the first virtual private network server receives a protocol data unit from a client device and identifies the second virtual private network server, in accordance with a routing control policy defined by the hierarchical-context area network, as a current point of egress for transporting the protocol data unit through the hierarchical-context area network to send to an external device.
