Global Virtual Network Tunneling for Low-Latency Path Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network optimization technologies, such as WAN optimization and VPNs, often result in high latency and cost due to point-to-point connections, lack of control over traffic paths, and reliance on expensive dedicated circuits or unstable internet connections, leading to poor user experience and inefficient data transmission.
Innovation Solution
A global virtual network (GVN) that provides secure, optimized network connectivity over standard internet connections using a mesh of devices linked by advanced tunnels, with automated traffic routing and encryption, ensuring efficient data flow through encrypted tunnels between endpoint devices and access point servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If point-to-point WAN optimization devices are used to connect LANs, then data transmission security and compression are improved, but connection stability deteriorates when internet connection is poor and path control is lost
Solution Approach 1:
The patent introduces WAN optimization devices at LAN edges that act as intermediaries to establish controlled tunnels through the internet. These devices implement protocols like IPSec and GRE to create stable, manageable point-to-point connections, resolving the contradiction by providing both internet connectivity and path control through intermediary tunneling mechanisms.
2Reliability
If MPLS or DDN dedicated circuits 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 employs standard internet connections with overlay tunneling protocols instead of expensive dedicated circuits. The tunneling technology (IPSec, GRE, L2TP) creates virtual dedicated connections over public internet infrastructure, achieving comparable QoS without the high installation costs and lengthy deployment times of physical dedicated lines.
3Ease of operation
If traffic is routed through remote LAN gateway to access local servers, then internet connectivity is maintained, but global transit time increases significantly causing slowdown
Solution Approach 1:
The patent introduces local exit points or cache servers at remote LAN locations that act as intermediaries for accessing local resources. Instead of routing all traffic through the headquarters gateway, these local intermediaries provide direct access paths for local servers, reducing global transit time while maintaining internet connectivity through the optimized WAN tunnel.
4Reliability
If encrypted tunnels are established between routers for security, then data protection is improved, but control over routes between points is lost due to reliance on internet policy
Solution Approach 1:
The patent implements WAN optimization devices that serve as controlled intermediaries, establishing encrypted tunnels using protocols like IPSec while maintaining routing control through gateway devices. The optimization devices implement policies for traffic selection, compression, and tunnel management, resolving the contradiction by providing both encryption and route control through a layered architecture where the optimizer controls the tunnel endpoints.
