VOIP Route Selection Using Dynamic QoS Metrics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VOIP route selection methods do not effectively leverage quality-of-service (QoS) metrics to optimize data stream routing, leading to suboptimal call quality and network performance.
Innovation Solution
A method that determines QoS metrics for each network path, assigns quality scores, and modifies the stream-routing ratio to prioritize high-scoring paths, ensuring that new data streams are routed over high-quality network paths, thereby optimizing call quality and network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current VOIP route selection methods are used, then routing decisions are made, but call quality and network performance are suboptimal because QoS metrics are not effectively leveraged
Solution Approach 1:
The system continuously monitors QoS metrics for each network path and uses this feedback to dynamically adjust stream-routing ratios. Call quality metrics are collected, analyzed, and fed back into the routing decision-making process, creating a closed-loop system that adapts to changing network conditions and optimizes both call quality and network performance
Solution Approach 2:
The stream-routing ratios are made dynamic rather than static, allowing the system to adapt routing proportions based on real-time QoS metric analysis. The routing configuration is continuously adjusted according to measured call quality, enabling the system to respond to changing network conditions and optimize performance metrics
2Reliability
If stream-routing ratio is modified to prioritize high-quality paths, then call quality is enhanced, but system complexity increases due to continuous monitoring and adjustment
Solution Approach 1:
The routing system performs self-optimization by automatically monitoring its own QoS metrics and adjusting stream-routing ratios without external intervention. The system autonomously collects performance data, analyzes call quality metrics, and modifies routing configurations based on its own operational feedback, reducing the need for manual configuration and external control mechanisms
3Productivity
If QoS metrics are continuously monitored for all data streams, then routing optimization is improved, but measurement and processing complexity increases
Solution Approach 1:
The system monitors QoS metrics for a representative sample of data streams rather than attempting to analyze every single stream in detail. By measuring metrics for a partial set of streams and extrapolating trends, the system achieves sufficient routing optimization without the overwhelming complexity of comprehensive continuous measurement of all individual streams

AI summary
A method includes determining quality-of-service (QoS) metrics for each of a plurality of data streams routed by a node according to a stream-routing ratio that specifies a proportion of total data streams to be routed over each of a plurality of network paths. The method also includes determining a quality score for each of the plurality of network paths based on the QoS metrics. The method further includes modifying the stream-routing ratio based on the quality scores for the plurality of network paths to produce a modified ratio for routing new data streams, the modified ratio being selected to leverage particular ones of the plurality of network paths having high quality scores. The method still further includes applying the modified ratio to the node.
