Virtual Network Edge Overlay for Diverse Carrier Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network technologies, such as link aggregation and MPLS, face limitations in connecting diverse network carriers and providing optimal network performance across long distances, leading to suboptimal performance due to long haul effects and lack of carrier diversity.
Innovation Solution
A network system that utilizes a virtual network overlay with cloud network controllers and concentrators to manage data traffic, enabling bonding or aggregation of diverse network connections, and providing transparent encryption and encapsulation, while using intelligent packet distribution to optimize traffic across multiple network paths.

Engineering Contradiction Analysis
1Productivity
If bonding/aggregation of links is provided at client sites to increase throughput, then network performance from client to network backbone is improved, but network impedance increases and performance across the entire network path deteriorates
Solution Approach 1:
The network path is segmented into two distinct segments: a bonded/aggregated link segment at the client site for high throughput access to the network backbone, and a separate network backbone segment that maintains its own optimized routing. This segmentation allows each segment to be optimized independently, resolving the contradiction between achieving high throughput at the client side and maintaining overall network performance.
Solution Approach 2:
The network backbone acts as an intermediary between the bonded/aggregated links at client sites and the final destination. By introducing this intermediary layer with its own optimized routing capabilities, the system can achieve high throughput at the client side while the backbone manages the longer path efficiently, preventing the deterioration of overall network performance.
2Productivity
If long haul bonding/aggregation is used to connect distant locations, then network performance from client to backbone is improved, but network impedance and latency increase
Solution Approach 1:
The network path is divided into a local bonded/aggregated segment for high-speed access and a separate long-haul backbone segment. This segmentation allows the bonded links to provide high throughput for local traffic while the backbone handles the long-distance routing independently, minimizing the cumulative impact of latency over the entire path.
Solution Approach 2:
The system transitions from a single-dimensional end-to-end bonded link approach to a multi-dimensional architecture where bonded links operate at the client edge dimension and the backbone operates at the core routing dimension. This dimensional separation allows each layer to optimize for its specific function, reducing overall latency despite long distances.
3Productivity
If traditional bonding/aggregation technologies are used, then link throughput is increased, but carrier diversity and network performance optimization are limited
Solution Approach 1:
The network backbone is designed with universal routing capabilities that can handle traffic from multiple different carriers and bonded link configurations. This multi-functional backbone can optimize paths for diverse carriers independently while maintaining high throughput, thereby enabling carrier diversity without sacrificing performance.
Solution Approach 2:
The system introduces dynamic routing capabilities at the backbone level that can adapt to different carrier configurations and bonded link setups. This dynamic adjustment allows the network to optimize performance for each carrier combination, enhancing both throughput and carrier diversity support.

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 re-mote network server components.
