Local Internet QoS Egress Queuing for Branch Office Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional enterprise networks are costly and require technical support for SMBs due to their design primarily for large corporations, making them unsuitable for small and medium businesses, especially in remote office locations without on-site IT personnel, leading to increased expenses for deployment and maintenance.
Innovation Solution
Implementing a local internet with quality of service (QoS) egress queuing method that establishes data tunnels between a WAN interface of a local host device and remote host devices, allowing direct internet communication and secure filtering of internet traffic, reducing the need for centralized tunneling and thus minimizing latency and congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional enterprise networks are deployed for SMB remote offices, then network service capability is provided, but deployment and maintenance costs significantly increase due to requiring certified technicians
Solution Approach 1:
The patent implements self-service through automated network configuration and management capabilities. The system automatically provisions network services, configures routing, and manages remote office connections without requiring on-site IT personnel or certified technicians. This automation eliminates the need for expensive service calls while maintaining reliable network connectivity for SMB remote offices.
2Reliability
If centralized tunneling is used for internet access in remote offices, then security is improved, but latency and network congestion increase
Solution Approach 1:
The patent segments the network architecture into distributed edge locations that can independently handle local internet traffic. Instead of forcing all traffic through a single centralized tunnel, the system creates multiple regional internet access points. This segmentation allows traffic to be processed locally, reducing latency and congestion while maintaining security through distributed enforcement points.
Solution Approach 2:
The patent introduces a new dimensional approach by implementing multi-path routing capabilities. Traffic can be directed through different dimensions of the network topology - either through centralized tunnels for security-sensitive traffic or through local internet access points for time-sensitive traffic. This dimensional flexibility allows the system to optimize for both security and latency based on traffic requirements.

AI summary
Local internet functionality may allow host devices positioned in branch office locations to securely communicate outgoing internet traffic directly over the internet. Local internet functionality may also allow said host devices to securely receive incoming internet traffic through the creation and tracking of local internet sessions. Local internet functionality is achieved by forwarding egress internet traffic over a local internet virtual pathway extending to a WAN interface/port of a local host device. The WAN interface/port is configured to communicate traffic received over the local internet virtual pathway directly over the internet, while communicating all other egress traffic over secure tunnels of the virtual edge router. The WAN interface/port is further configured to monitor outgoing local internet traffic to create and track local internet sessions.
