Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks lack the ability to effectively determine and enforce quality-of-service policies based on the application types of data packets, leading to inefficient bandwidth utilization and varying levels of service across different applications.
Innovation Solution
A communication system with a wireless access node and packet processing system that identifies wireless device and sector identifiers, determines application types, creates activity profiles, and enforces quality-of-service policies to manage bandwidth allocation dynamically, ensuring optimal service levels based on traffic patterns and user agreements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packet inspection is performed to determine application types, then quality-of-service enforcement is improved, but device complexity increases
Solution Approach 1:
The system divides the network into multiple sectors, each with its own activity profile and quality-of-service policies. The wireless access node segments traffic by sector and device identifier, allowing independent quality-of-service enforcement per sector without requiring complex global analysis. This segmentation enables reliable quality-of-service differentiation while keeping individual node complexity manageable.
Solution Approach 2:
The patent introduces an intermediary mechanism where the wireless access node extracts and forwards sector identifiers and device identifiers to the packet processing system. This intermediary role allows the access node to perform simple traffic classification without implementing complex quality-of-service decision logic, thereby improving quality-of-service enforcement while limiting the complexity increase at the access node.
2Productivity
If dynamic quality-of-service policies are enforced, then bandwidth utilization is improved, but processing requirements increase
Solution Approach 1:
The system performs preliminary action by creating activity profiles that capture historical traffic patterns, application types, and bandwidth usage characteristics before quality-of-service decisions are needed. These pre-computed profiles enable the packet processing system to make rapid quality-of-service adjustments based on matching current traffic against known patterns, improving bandwidth utilization without requiring complex real-time analysis for each packet.
Solution Approach 2:
The system implements feedback mechanisms where the packet processing system continuously monitors sector activity profiles and adjusts quality-of-service policies based on observed traffic patterns and bandwidth utilization. This feedback loop enables dynamic optimization of bandwidth usage while processing requirements remain manageable because the system learns from historical patterns rather than requiring complex real-time computation for each decision.
