Gateway QoS Classification for Heterogeneous Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing residential gateways struggle to optimally manage data transmission across heterogeneous network segments built on different physical interfaces, leading to sub-optimal patchwork networks with varying capacity, latency, and packet loss, which affects the quality of service and user experience.
Innovation Solution
A networking device equipped with a classification agent and a Quality of Service (QoS) monitoring agent that extracts information from incoming data frames, applies classification rules to determine the best interface for forwarding, and dynamically updates these rules based on QoS information from subnet interfaces to optimize data transfer across native and legacy cabling segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If standard bridging and routing rules are used for forwarding packets, then the gateway can handle basic traffic forwarding, but it cannot optimally manage data transmission across heterogeneous network segments with varying capacity, latency, and packet loss
Solution Approach 1:
The patent implements dynamic QoS parameter collection from multiple network interfaces and real-time update of classification rules based on current network conditions. The system continuously monitors bandwidth, latency, and packet loss metrics, then dynamically adjusts forwarding decisions to adapt to changing network segment capabilities, resolving the contradiction between efficient data transmission and adaptability to heterogeneous segments.
Solution Approach 2:
The patent establishes a feedback mechanism where QoS parameters are collected from network interfaces, processed to determine optimal forwarding paths, and used to update classification rules. This closed-loop feedback system enables the gateway to learn from actual network performance and continuously improve its forwarding decisions, achieving both high productivity and adaptability to diverse network segments.
2Ease of manufacture
If pre-existing cabling infrastructure is used to deploy point-to-point or point-to-multipoint links, then installation is simplified, but the result is a sub-optimal patchwork of network segments with poor interaction with dedicated LAN equipment
Solution Approach 1:
The patent changes the operational parameters of existing cabling infrastructure by dynamically adjusting QoS classification rules based on real-time network conditions. Instead of requiring physical reconfiguration of the patchwork network, the system optimizes performance by modifying forwarding parameters, achieving improved productivity while maintaining the ease of deployment of pre-existing cabling.
3Device complexity
If classification rules are statically configured, then the gateway can provide basic flow-based forwarding, but it cannot dynamically adapt to changing network conditions and service requirements
Solution Approach 1:
The patent implements a self-service mechanism where the gateway automatically collects QoS parameters from its own network interfaces, processes this information, and updates its classification rules without external intervention. The system serves itself by monitoring its own network conditions and autonomously adjusting its forwarding behavior, reducing the complexity of manual rule management while achieving high adaptability.
