This paper is concerning of Erlang formulas practical approval and their usage with video flow transfer in IP networks. Erlang formulas were simulated in MATLAB program. Practical verification was realized in defined environment by using of designed video source. The result is comparison of loss calculated by MAT-LAB and loss of real video data transfer. IP networks were not designed for providing multimedia services at the beginning. These networks were intended for data transfer without predefined paths so that in case of breakdown of one of the routers, other path could be chosen. Path of packet can change and so can change transfer parameters.
