Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing network optimization technologies, such as WAN optimization and VPNs, often result in high latency and lack control over traffic flow, leading to poor user experience and increased costs due to fixed point-to-point connections or reliance on unstable internet routes, especially when connecting remote LANs to cloud-based servers.

Innovation Solution

A Global Virtual Network (GVN) system that uses a mesh of distributed devices connected by advanced tunnels, employing Advanced Smart Routing (ASR) to optimize data flow over standard internet connections, ensuring secure, reliable, and fast connectivity by continuously monitoring and adapting routes through automated systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If WAN optimization is used to compress and secure data flow, then transmission cost is reduced, but latency increases and connection stability deteriorates

Engineering Contradiction:

Improvetransmission costVSAvoidlatency

Core Design Contradiction:

Loss of energyVSLoss of time

Solution Approach 1:

The patent segments the network connection into multiple parallel tunnels instead of using a single optimized tunnel. This allows data to be distributed across multiple paths, reducing the impact of any single tunnel's latency while maintaining compression benefits across the network as a whole.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces intermediary routing nodes that act as mediators between the WAN optimization devices. These intermediaries help route traffic through optimal paths, reducing latency while preserving the compression and security benefits of the optimization layer.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If fixed point-to-point connections are used, then connection stability is improved, but adaptability to different network conditions deteriorates

Engineering Contradiction:

Improveconnection stabilityVSAvoidadaptability to network conditions

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic tunnel selection and routing, where the system continuously monitors network conditions and adapts the active tunnels accordingly. This allows the connection to maintain stability through consistent performance monitoring while adapting to changing network conditions by switching between available tunnels.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of tunnel state from static to dynamic, allowing tunnels to be created, activated, deactivated, and removed based on real-time network conditions. This enables the system to maintain stable connections through careful parameter management while adapting to different network environments.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If MPLS or DDN lines are used for WAN connectivity, then quality of connection and QOS guarantees are improved, but installation time and cost increase

Engineering Contradiction:

Improvequality of connectionVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent creates virtual copies of dedicated connection qualities over standard internet infrastructure using multiple encrypted tunnels. Instead of physically installing MPLS or DDN lines, the system replicates their reliability and QoS characteristics through software-based tunneling and routing optimization.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical/physical installation of dedicated circuit infrastructure with a software-based tunneling system. This substitution eliminates the need for physical line drawing and hardware installation while achieving similar connection quality through encrypted tunnel protocols and intelligent routing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If traffic is routed through remote LAN gateway to Internet and back, then connectivity is established, but global transit time increases significantly

Engineering Contradiction:

ImproveconnectivityVSAvoidglobal transit time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent performs preliminary routing decisions at the tunnel endpoint devices, determining the optimal path before traffic enters the WAN optimization system. This preliminary action prevents traffic from taking suboptimal routes through remote gateways by pre-calculating and establishing the fastest path through available tunnels.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent adds a new dimensional layer of routing control by implementing virtual interfaces that operate above the traditional tunnel level. This additional dimension allows for sophisticated routing decisions that can direct traffic through optimal paths without being constrained by traditional gateway-based routing, effectively reducing global transit time.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
