Solution Overview

Problem

Existing congestion control mechanisms cause queuing delay and adversely affect latency-sensitive traffic, and traditional broadband services lack user-centric customization, leading to suboptimal network traffic handling and customer experience.

Innovation Solution

Implement a dual queue system at the LAN and WAN levels, allowing users to specify which network traffic categories receive preferential low latency treatment, using a user interface to manage traffic flows and apply policies dynamically based on customer preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If traditional congestion control mechanisms are used to manage network traffic, then network capacity is maintained, but queuing delay increases and latency-sensitive traffic performance deteriorates

Engineering Contradiction:
Improvenetwork capacityVSAvoidqueuing delay
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The patent segments network traffic into different categories (latency-sensitive and non-latency-sensitive) and processes them through different queues. The system divides the network traffic flow into multiple streams, applying different handling policies to each category, thereby reducing queuing delay for latency-sensitive traffic while maintaining overall network capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different quality characteristics to different portions of network traffic based on their requirements. Latency-sensitive traffic receives preferential treatment with lower queuing delay, while non-latency-sensitive traffic follows traditional congestion control. This local differentiation resolves the contradiction by optimizing each traffic type according to its specific needs.

Inventive Principle:
Principle #3Local quality

2Loss of time

If dual queue system is implemented to reduce latency, then latency-sensitive traffic performance improves, but device complexity increases

Engineering Contradiction:
ImprovelatencyVSAvoidqueue management complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The system enables end users to self-configure their own traffic priorities through an intuitive interface. Users independently identify and prioritize their latency-sensitive applications without requiring complex system configuration or expert intervention. This self-service approach simplifies the overall system complexity while maintaining the dual-queue latency reduction benefits.

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If traditional broadband service is provided without user customization, then service delivery is simplified, but customer experience and traffic handling optimization deteriorate

Engineering Contradiction:
Improveservice delivery simplicityVSAvoidtraffic handling adaptability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent transforms static broadband service into a dynamic, user-adaptable system. Users can dynamically prioritize different applications and traffic types based on their changing needs. The system adapts to individual customer requirements while maintaining simplified service delivery through automated detection and configuration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements feedback mechanisms where user preferences and traffic patterns are continuously monitored and used to automatically adjust queue assignments. This feedback loop enables the system to adapt to changing customer needs without requiring complex manual configuration, resolving the contradiction between simplicity and adaptability.

Inventive Principle:
Principle #23Feedback

AI summary

Systems and methods provide a LAN connected to a WAN, where each of a first queue for preferential network traffic and a second queue for non-preferential network traffic is provided at least in part by a second networking equipment associated with the WAN. The system may receive, via a user interface, input identifying a particular category of network traffic, wherein the received input causes network traffic corresponding to the particular category to be processed (e.g., delivered) using the first queue instead of the second queue. The system may, based at least in part on detecting, at the first networking equipment, that a portion of subsequent network traffic associated with a request by a device of the plurality of devices connected to the LAN corresponds to the particular category, transmit instructions to the second networking equipment to process the portion of subsequent network traffic using the first queue instead of the second queue.
