Dynamic Traffic QoS Adjustment via On-Demand Request
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packet-switching networks face challenges in dynamically adjusting traffic quality of service (QoS) to meet varying user demands, leading to issues like packet drop, jitter, and delayed delivery, especially under heavy traffic loading, where all data streams have the same priority without the ability to change until carrier intervention.
Innovation Solution
A process and network device that dynamically adjust traffic QoS on-demand by receiving enhanced QoS requests from users, prioritizing traffic flows, and routing information according to predefined enhanced QoS settings, utilizing routers with QoS management capabilities to establish prioritized channels and record usage for billing purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traffic priority is set for a particular path or flow, then the quality of service for that flow is improved, but the traffic priority does not change until a carrier decides to update, reducing adaptability to dynamic user demands
Solution Approach 1:
The patent implements dynamic QoS adjustment by allowing users to request priority service on-demand rather than relying on static carrier-configured priorities. The system dynamically modifies traffic flow characteristics in response to user requests, enabling real-time adaptation to changing network conditions and user needs without requiring carrier intervention.
Solution Approach 2:
The patent enables users to self-initiate QoS adjustments by sending requests to the network operator. Instead of waiting for carrier decisions, users can autonomously request priority treatment for specific traffic flows, and the system automatically processes these requests by modifying routing and priority settings without requiring manual carrier configuration.
2Productivity
If all data streams have the same traffic priority, then network simplicity is maintained, but throughput for voice, video, and multimedia services becomes too low under heavy loading conditions
Solution Approach 1:
The patent applies local quality by assigning different priority levels to different traffic flows based on their specific requirements. Instead of uniform priority treatment, the system identifies and prioritizes specific data streams (such as voice, video, or multimedia) that require higher throughput, applying differentiated quality attributes to local portions of the traffic flow while maintaining overall network management.
3Speed
If high-speed communication signaling protocol is implemented, then bandwidth and speed for audio, video, and data transmission are enhanced, but packet drop, jitter, and arrival delay occur under heavy traffic loading
Solution Approach 1:
The patent segments traffic into different priority classes, separating high-priority traffic (voice, video, multimedia) from standard traffic. This segmentation allows the network to handle different types of data streams with appropriate priority treatment, ensuring that critical packets receive preferential routing and resource allocation, thereby reducing packet drop and jitter for time-sensitive applications while maintaining high transmission speeds.
Data Source
AI summary
A method and apparatus for dynamically adjusting traffic quality of service (“QoS”) on-demand over a communications network are disclosed. The process, in one embodiment, is configured to receive an enhanced QoS request from a user via a first node over a communications network. Upon prioritizing traffic flow in accordance with the enhanced QoS request, the enhanced QoS request associated with the first node is recorded. Upon acknowledging the enhanced traffic QoS, the process routes the information to the first node in accordance to a predefined enhanced QoS.
