Abstract
Способ проверки виртуального соединения для передачи мультимедийных данных с заданными характеристиками, заключающийся в том, что устанавливают допуск на изменение качества речевого сигнала, осуществляют тестирование сети повышенной и пониженной нагрузкой, по результатам тестирования сети находят оптимальные для текущего соединения параметры кодека и передачи речевого сигнала, устанавливают найденные параметры кодека и передачи речевого сигнала как текущие, с определенной периодичностью вычисляют изменение качества речевого сигнала, в случае, если вычисленное изменение качества речевого сигнала превышает установленный допуск на изменение качества речевого сигнала, вновь осуществляют тестирование сети повышенной и пониженной нагрузкой, по результатам тестирования сети находят оптимальные для текущего соединения параметры кодека и передачи речевого сигнала, устанавливают найденные параметры кодека и передачи речевого сигнала как текущие и вновь с определенной периодичностью вычисляют изменение качества речевого сигнала, отличающийся тем, что до процесса мультимедиа соединения определяют показатели качества для виртуального соединения, такие как время задержки, джиттер, размер передаваемого кадра, процент допустимой потери пакетов транспортным протоколом, осуществляют тестирование виртуального соединения пониженной и повышенной нагрузкой в ходе которого определяют граничные значения показателей качества виртуального соединения для пониженной и повышенной нагрузки, осуществляют расчет допустимых значений показателей качества виртуального соединения, после чего в процессе мультим�A method for verifying a virtual connection for transmitting multimedia data with specified characteristics, which consists in setting a tolerance for changing the quality of a speech signal, testing the network with increased and reduced load, using the network testing results, find the codec and speech signal parameters that are optimal for the current connection, set the found parameters of the codec and the transmission of the speech signal as current, with a certain frequency calculate the change in the quality of the speech signal ala, if the calculated change in the quality of the speech signal exceeds the established tolerance for changing the quality of the speech signal, the network is again tested with increased and reduced load, according to the results of network testing, the codec and speech signal transmission parameters that are optimal for the current connection are found, the found codec parameters are set and speech signal transmissions as current and again with a certain frequency calculate the change in the quality of the speech signal, characterized in that before the process m light connections determine the quality indicators for a virtual connection, such as delay time, jitter, transmitted frame size, percentage of allowable packet loss by the transport protocol, test the virtual connection with reduced and increased load during which the boundary values of the virtual connection quality indicators for reduced and increased load are determined , calculate the acceptable values of the quality indicators of the virtual connection, and then in the process of multi
