Packet Reclassification and Priority Queue Control for Mixed Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Low Latency, Low Loss, Scalable throughput (L4S) protocols face challenges in managing traffic differentiation, leading to adverse impacts on user experiences of applications with varying sensitivity levels, particularly in real-time applications like AR/VR and online gaming, due to indiscriminate LAS handling.
Innovation Solution
A communication management resource analyzes data packets to determine and adjust latency classifications, modifying tags to ensure appropriate queuing based on packet type and sensitivity, using machine learning for traffic classification and dynamic queue management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If LAS handling is applied to all traffic types, then latency is reduced for latency-sensitive applications, but user experience deteriorates for applications with varying sensitivity levels
Solution Approach 1:
The patent segments traffic into different categories based on latency sensitivity by analyzing packet characteristics and applying appropriate LAS handling only to suitable traffic types. This prevents indiscriminate LAS application and allows differentiated treatment of various application traffic
Solution Approach 2:
The patent applies LAS handling selectively to specific traffic types rather than uniformly to all traffic. By identifying latency-sensitive applications through packet analysis and applying LAS marking only to those types, the system provides localized quality optimization without adversely affecting other traffic
2Loss of time
If LAS handling is applied to all traffic, then queue waiting time is reduced, but queue-dependent applications suffer from misuse
Solution Approach 1:
The patent performs preliminary classification of traffic packets before they enter the queueing system by analyzing packet characteristics and determining latency sensitivity. This preliminary action ensures that only appropriate traffic receives LAS handling, preventing misuse that would adversely affect queue-dependent applications
3Ease of manufacture
If no traffic classification mechanism exists, then LAS can be simply implemented, but ISPs cannot designate which traffic should receive LAS handling
Solution Approach 1:
The patent enables traffic to self-identify its latency sensitivity requirements through packet characteristic analysis. The system automatically categorizes traffic types and applies appropriate LAS handling without requiring complex external classification mechanisms, maintaining simplicity while enabling ISP control
Data Source
AI summary
A system as discussed herein includes communication management hardware. The communication management hardware: receives a first data packet including a first data payload, the first data packet transmitted for delivery to a destination network address; determines a first latency classification assigned to the first data packet; assigns a second latency classification to the first data packet as a substitute to the first latency classification; and forwards the first data packet for delivery to the destination network address in accordance with the second latency classification.
