Network Overlay Aggregation for Long Haul Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network technologies, such as link aggregation and WAN optimization, often result in suboptimal network performance due to long haul effects when connecting distant client sites, as they do not fully utilize the capabilities of the network backbone, leading to impaired throughput and latency.
Innovation Solution
A network system that includes client site network components bonding or aggregating diverse connections, a network server component with a virtual control plane interface, and a cloud network controller to manage data traffic, establishing a virtual network overlay that incorporates long haul network paths, providing transparent encryption and encapsulation, and utilizing Multi-Directional Pathway Selection for pre-emptive failover and Quality of Service management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bonding or aggregation of diverse network connections is implemented at client sites to increase throughput, then network performance between client sites is improved, but long haul effects and network impedance occur when connecting distant locations
Solution Approach 1:
The patent segments the network connection into two distinct parts: a bonded/aggregated connection at the client site for high throughput, and a separate connection to the network backbone for reliable long-haul transmission. This segmentation allows each part to be optimized independently, resolving the contradiction between throughput improvement and performance stability.
Solution Approach 2:
The patent introduces a network backbone as an intermediary between client sites. Instead of directly bonding connections between distant client sites (which causes long haul effects), the bonded connections at each site communicate through the high-performance network backbone, eliminating network impedance while maintaining throughput benefits.
2Ease of operation
If bonded/aggregated links are maintained across the network backbone for long haul connections, then connectivity between distant locations is achieved, but network impedance results in suboptimal performance
Solution Approach 1:
The patent separates the connectivity function from the performance-critical data transmission path. Client sites maintain bonded connections for ease of operation, while the network backbone handles high-performance data transmission independently, eliminating network impedance.
Solution Approach 2:
The network backbone serves as an intermediary that receives data from bonded client connections and transports it efficiently between distant locations. This intermediary approach prevents direct long-haul bonded connections from causing network impedance, maintaining both connectivity and performance.
3Productivity
If existing bonding technologies are used to increase network capacity, then throughput between client sites is improved, but the solution does not fully utilize network backbone capabilities
Solution Approach 1:
The patent divides the network architecture into client-side bonded connections and backbone-side high-performance connections. This segmentation allows the client sites to utilize bonding for throughput improvement while the network backbone operates independently at its full capability, achieving both goals simultaneously.

AI summary
A network system is provided between at least a first client site and a second client site. A client site network component is implemented at least at the first client site, the client site network component aggregating one or more diverse network connections so as to configure an aggregated connection that has increased throughput. At least one network server component may be configured to connect to the client site network component using the aggregated connection. A cloud network controller may be configured to manage the data traffic and a virtual edge providing transparent lower-link encryption for the aggregated connection between the client site network component and the network server component. The network server component includes a virtual control plane interface configured to establish a unicast path between the network server component and each of a plurality of remote network server components.
