End-to-End QoS Adjustment for Network Traffic Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Quality of Service (QoS) techniques in mobile wireless communication systems primarily focus on optimizing individual network elements for packet scheduling, failing to address end-to-end (E2E) application data flow optimization across the entire network, leading to suboptimal performance due to bandwidth restrictions and traffic overloading.
Innovation Solution
Implementing a network management system that adjusts QoS parameters across different network segments to redistribute resources, prioritizing affected application data flows by identifying spare resources and reallocating them to maintain E2E performance requirements while ensuring unaffected flows retain sufficient resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional QoS techniques optimize individual network elements for packet scheduling, then local network element performance is improved, but end-to-end application data flow performance deteriorates
Solution Approach 1:
The patent segments the end-to-end network path into multiple network elements and independently optimizes QoS parameters for each segment based on local conditions and overall E2E performance requirements, rather than treating the entire network as a single optimized unit
Solution Approach 2:
The patent applies different QoS parameter adjustments to different network elements along the E2E path based on their specific characteristics, traffic conditions, and resource availability, rather than applying uniform optimization across all network elements
2Quantity of substance
If network resources are restricted in certain segments, then other segments have sufficient resources, but overall E2E performance deteriorates due to backpressure
Solution Approach 1:
The patent dynamically adjusts QoS parameters in response to detected backpressure conditions, temporarily increasing priority or resource allocation in affected network segments to maintain E2E performance while resources are available
Solution Approach 2:
The patent changes QoS parameters such as packet priority, scheduling weight, or resource allocation in specific network segments to compensate for backpressure and maintain acceptable E2E data flow performance
Data Source
AI summary
A device may manage end-to-end traffic across a network based on adjusting Quality of Service (QoS) parameters. The device may receive performance requirements for packets corresponding to different applications and QoS levels within segments across the network, and measure performance values along the segments across the network. The device may also identify the application data flows and their associated network locations failing to meet performance values across network segments, and detect an application data flow failing to meet end-to-end (E2E) performance requirements. The device may determine network location(s) to adjust the QoS parameters of the detected application data flow, and adjust its QoS parameters at the determined network location(s) to bring the detected application data flow into compliance with its E2E performance requirements, while maintaining E2E performances compliance of other application data flows.
