QoS Service Advisor for VoIP Network Path Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication systems, particularly those involving VoIP and PSTN networks, often experience unpredictable performance due to complex network configurations, heavy traffic, server overload, and interference, which can lead to poor quality of service for real-time applications like VoIP, videoconferencing, and teleconferencing.
Innovation Solution
A Quality of Service (QOS) based service advisor system that measures and analyzes performance levels of communication paths, identifies network segments and devices, and adjusts communication parameters to improve service quality by rerouting traffic and optimizing algorithms such as forward error correction and de-jitter buffers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the network system handles multiple communication paths and heavy traffic, then the system capacity and connectivity are improved, but the performance predictability and quality of service deteriorate
Solution Approach 1:
The patent segments the communication path into multiple network segments and measures performance metrics for each segment independently. This allows the system to handle complex multi-path communications while maintaining predictable performance by analyzing and managing each segment separately rather than treating the entire path as a single unit.
Solution Approach 2:
The patent implements a feedback mechanism where performance metrics are continuously measured and reported back to identify under-provisioned segments. This feedback loop enables dynamic adjustment and optimization of network resources to maintain reliable performance even as system capacity increases and traffic patterns change.
2Adaptability or versatility
If network segments are added to increase system capability, then the connectivity and service coverage are improved, but the identification and troubleshooting of performance issues become more difficult
Solution Approach 1:
By dividing the communication path into distinct network segments and measuring performance metrics for each segment separately, the patent makes it easier to identify which specific segment is under-provisioned or causing performance issues. This segmentation approach transforms a complex troubleshooting problem into manageable individual segment analyses.
Solution Approach 2:
The patent uses visual indicators (color-coded performance metrics) to represent the performance status of different network segments. This allows operators to quickly identify under-provisioned segments through color changes rather than analyzing raw numerical data, significantly reducing the difficulty of detecting performance issues in complex networks with many segments.
3Ease of operation
If real-time communication applications are supported, then the service quality and user experience are improved, but the sensitivity to network performance variations increases
Solution Approach 1:
The patent performs preliminary measurement and identification of under-provisioned network segments before real-time communications are affected. By proactively detecting performance issues in network segments, the system can take corrective actions in advance to ensure that real-time applications maintain high service quality without being adversely affected by network variations.
