Managing quality of experience for video streaming traffic
The granted patent US12069122B2 outlines a method and system for managing Quality of Experience (QoE) specifically for video streaming traffic on a network. The method involves collecting data from multiple video streaming traffic flows and creating a model that assesses the health of video buffers. It further includes determining factors related to new video streaming traffic, analyzing these factors using the established model, and ultimately calculating a QoE score. The data collected encompasses various parameters such as video buffer health, resolution, throughput, and device type. The analysis process involves assigning weights to each factor and aggregating these to derive the QoE score. Additionally, the method allows for notifying network providers when QoE scores fall below a specified threshold.
The system described in the patent comprises several modules, including a factor determination module for data collection, a model module for creating the QoE model, and an analysis module for evaluating new traffic flows. The QoE engine is responsible for calculating the QoE score and can also notify network providers of low scores. Furthermore, the system can aggregate QoE scores across different network dimensions, such as location, network type, application type, and application provider. The patent also mentions the capability of implementing traffic policies or actions based on the determined QoE scores, enhancing the management of video streaming traffic to improve user experience.
