FIELD: instrument making.
SUBSTANCE: invention relates to device and method for monitoring of performance in communication network, for example, working characteristics related to streaming media (such as, for example, streaming video) in communication network. Method of monitoring performance streaming media services, used for delivery of multimedia streams to user equipment, device includes step of determining encoding feature first multimedia stream (201), on which monitoring. Model of functional relationship is established between first key performance indicator System Service (S-KPI) and one or more Key performance indicators Resource Services (R-KPI) for first flow multimedia (203).
EFFECT: installed model functional relationship is used for monitoring of second media stream, having same coding characteristic as first media stream (205).
