The method of quality parameters measurement and evaluating of audio-video data transmission

Dagmara Mazur


The paper describes the passive method of measuring the values of the data transmission quality parameters during audio-video calls performed in computer network. It also describes how the computer network can be evaluated in terms of providing an adequate level of service quality during audio-video data transmission. One can find in the paper the computer network testing procedure as well as results of measurements performed in a given test environment with the usage of described method. Presented method not only allows for computer network troubles diagnosis, but also for evaluation of newly build data quality transmission protocol’s mechanisms.
