ITU-T Q.3912 PDF

This Recommendation provides the measurement metrics of stream service monitoring and defines a set of parameters that will impact the quality of streaming services in the next generation network (NGN). These parameters are generated by network elements, such as terminal elements, connection elements or transmission elements. The definitions provided here are dependent on the NGN, which uses IP as the bearer protocol. This recommendation defines the approach of measurement of NGN streaming services parameters. The procedures on how to monitor these parameters are out of the scope of this Recommendation.
