ESTIMATION OF CONNECTION SETUP TIME FOR IPTV SERVICES USING THE IMS PLATFORM

The article presents the results of estimating the connection establishment time when providing IPTV services using the IMS platform. To estimate the connection establishment time, mathematical models have been developed for calculating basic delays in various sections of the network, taking into account the lengths of signaling messages. The results of estimating the connection establishment time and comparing the obtained results with the recommendations of the DSL forum (Digital Subscriber Line) and ITU-T are presented.
