Communication Quality Monitoring System with Dynamic Route Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication quality monitoring systems face high monitoring costs due to the need for extensive installation of monitoring functions across all network terminals and the requirement of multiple monitoring routes, leading to increased network load for information synchronization and collection.
Innovation Solution
A communication quality monitoring system that includes a normal monitoring route planning unit, a quality degrading point monitoring route planning unit, a forwarding rule configuring unit, a communication quality measuring unit, and a communication quality degrading point inferring unit, which dynamically determines and adjusts monitoring routes and packets to efficiently detect and specify quality degradation points within a network using an external controller for packet transfer route control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If monitoring functions are installed on all network terminals with multiple monitoring routes, then communication quality can be comprehensively monitored, but monitoring cost and network load increase significantly
Solution Approach 1:
The patent segments monitoring functions into two distinct units: a normal monitoring route planning unit for general quality monitoring and a quality degrading point monitoring route planning unit for locating specific degradation points. This segmentation allows comprehensive monitoring coverage while reducing overall system complexity by dividing responsibilities between specialized components.
Solution Approach 2:
The patent introduces an external controller as an intermediary that manages and coordinates multiple monitoring route planning units. This intermediary consolidates control logic, reducing the complexity burden on individual network terminals while maintaining comprehensive monitoring capabilities across the network.
2Reliability
If multiple monitoring routes are set for comprehensive network observation, then monitoring coverage is improved, but the number of monitoring packets and network load increase
Solution Approach 1:
The patent implements dynamic monitoring route adjustment where the quality degrading point monitoring route planning unit adaptively determines specific monitoring routes based on detected quality issues. Instead of statically configuring all possible monitoring routes, the system dynamically activates only the necessary routes, reducing monitoring packet quantity while maintaining comprehensive coverage when needed.
Solution Approach 2:
The patent applies local quality by directing monitoring resources selectively to specific network areas where quality degradation is detected. The quality degrading point monitoring route planning unit focuses monitoring efforts on affected regions rather than uniformly distributing monitoring packets across the entire network, thereby reducing overall packet quantity while maintaining effective coverage.

AI summary
Conventional network quality monitoring systems require high monitoring cost, because: physical maintenance cost is high, since monitors are required to install on many portion of the network; the number of monitoring flows is apt to increase; the cost for information synchronization between monitors is required; and the network cost to collect information from apparatuses is required. In the present invention, based on a network whose route is definable by an external controller and changing the monitoring flow route appropriately, it is possible to perform monitoring of the communication quality under a small number of monitoring terminals and flows. Further, the role of the monitoring flow is divided into the monitoring flows to monitor the quality degradation occurrence and to specify the quality degradation point. The former is used for normal time, and the latter is for the quality degradation time. Consequently, the network monitoring system reducing the cost is proposed.
