Solution Overview
Problem
Current IPTV service quality detection methods are manual and time-consuming, leading to high maintenance costs and prolonged detection periods, which negatively impact user experience due to issues like erratic displays and frame freezing.
Innovation Solution
An automated IPTV service quality detection method where network devices periodically monitor QoS parameters and send detection requests upstream when thresholds are exceeded, allowing for autonomous detection and identification of faulty devices within the network, reducing the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual detection method is used, then detection can be performed, but detection period is long and maintenance costs are high
Solution Approach 1:
The system enables self-service detection by allowing network devices to automatically monitor QoS parameters, generate detection requests when thresholds are exceeded, and identify faulty devices without human intervention. This automated self-diagnosis mechanism eliminates the need for manual troubleshooting and significantly reduces detection time.
Solution Approach 2:
The system implements feedback mechanisms where network devices continuously monitor QoS parameters and automatically trigger detection processes when quality degradation is detected. The detection results are fed back to identify the location and nature of faults, enabling continuous improvement and automatic adjustment of the monitoring system.
2Productivity
If automated detection is implemented, then detection speed improves, but system complexity increases
Solution Approach 1:
The detection system is segmented into independent functional modules: QoS parameter monitoring, threshold comparison, detection request generation, and fault identification. Each module operates independently but cooperatively, allowing the system to achieve high detection speed while maintaining manageable complexity through modular design.
Solution Approach 2:
The system performs preliminary actions by pre-configuring QoS parameter thresholds and detection rules before actual quality issues occur. Network devices are pre-programmed to automatically trigger detection when specific conditions are met, eliminating the need for complex real-time decision-making during fault events and simplifying the overall system architecture.
3Reliability
If frequent monitoring is performed, then quality issues are detected quickly, but network overhead increases
Solution Approach 1:
The system employs periodic monitoring at strategically determined intervals rather than continuous monitoring. Detection requests are triggered periodically or event-driven based on QoS threshold violations, ensuring reliable quality detection while minimizing unnecessary network traffic and energy consumption during normal operating conditions.
Solution Approach 2:
The system dynamically adjusts monitoring parameters such as detection intervals and threshold values based on network conditions and service requirements. This allows the system to maintain high detection reliability when needed while reducing network overhead during stable periods, optimizing the balance between monitoring intensity and resource consumption.

AI summary
The present invention relates to the field of communications technologies, and in particular, to an IPTV service quality detection technology. In an IPTV service quality detection method, an SDN controller receives, from a first network device, a video source identifier and information about a QoS parameter of a data packet flow that carries the video source identifier. When finding that the QoS parameter exceeds a preset threshold, the SDN controller sends a detection request message to at least one second network device on a path for forwarding an IPTV service data flow. After receiving a detection result returned by the at least one second network device, the SDN controller determines, based on the result, a network device that causes the QoS parameter to exceed the preset threshold. According to solutions provided in this application, IPTV service quality detection can be automatically initiated, a detection period can be effectively shortened, and no manual intervention is required, thereby effectively reducing operation and maintenance costs of detection.
