Virtual Network Interfaces for Smart Tunnel Routing
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 data flow paths, leading to inefficient and costly connections, especially when connecting remote LANs to the internet through corporate headquarters, doubling or tripling global transit times and providing poor user experiences.
Innovation Solution
A Global Virtual Network (GVN) system that utilizes a mesh of distributed devices linked by advanced tunnels, employing Advanced Smart Routing (ASR) to optimize data flow through encrypted, wrapped tunnels, continuously monitoring and adapting to changing conditions to ensure secure, reliable, and fast connectivity over standard internet connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If WAN optimization is used to compress and secure data flow, then data transmission cost is reduced, but latency increases and connection control is lost
Solution Approach 1:
The patent introduces a content delivery network (CDN) as an intermediary between the origin server and end users. The CDN caches content at distributed edge locations closer to users, acting as a mediator that serves content locally without requiring long-distance transmission through the original WAN optimization path, thus reducing latency while maintaining compression benefits
Solution Approach 2:
The system segments the content delivery process into multiple distributed nodes across the CDN network rather than a single centralized WAN path. Each CDN node independently handles local requests, dividing the overall transmission path into shorter segments that reduce total latency while maintaining the compression and security benefits at each segment
2Reliability
If dedicated circuits like MPLS or DDN are used for WAN connections, then connection quality and QOS guarantees are improved, but installation time and cost increase significantly
Solution Approach 1:
The patent creates virtual copies of dedicated circuit functionality through software-defined networking (SDN) and virtualization technologies. Instead of physically installing dedicated MPLS or DDN circuits, the system replicates their quality and reliability characteristics through virtual network overlays on top of standard internet infrastructure, achieving similar QOS guarantees without the lengthy physical installation process
Solution Approach 2:
The system replaces the mechanical/physical installation of dedicated circuits with software-based virtual network provisioning. The SDN controller automatically configures virtual paths, policies, and quality parameters through software, substituting the manual physical drawing of dedicated lines with automated digital provisioning that achieves comparable reliability instantaneously
3Ease of operation
If traffic is routed through corporate headquarters gateway to access internet, then centralized control is maintained, but global transit time doubles or triples
Solution Approach 1:
The patent adds a spatial dimension to content delivery by distributing CDN nodes across multiple geographic locations. Instead of all traffic converging to a single headquarters gateway point, content is delivered from the nearest geographic node, transforming the single-path hierarchical model into a multi-dimensional distributed mesh that reduces transit distance while maintaining centralized policy control through the SDN controller
4Reliability
If multiple tunnels are established for redundancy, then reliability is improved, but system complexity increases
Solution Approach 1:
The SDN controller implements self-service automation for tunnel management, automatically establishing, monitoring, and switching between multiple redundant tunnels without manual intervention. The system autonomously detects tunnel failures, selects alternative paths, and reconfigures routing policies, providing reliability through multiple tunnels while hiding the complexity through automated self-management capabilities
Data Source
AI summary
Systems and methods for connecting devices via a virtual global network are disclosed. In one embodiment the network system may comprise an endpoint device including a tunnel manager and a first virtual interface, an access point server including at least one tunnel listener and a second virtual interface. One or more tunnels are formed connecting the tunnel managers and tunnel listeners. The virtual interfaces provide a logical point of access to the one or more tunnels.
