Quality of service (QoS) on public telephonic networks for multimedia transmission systems

Abstract

The object of this paper is to determine which QoS maximum can be obtained by applying commercial telecommunications technology in the transmission of audio and video on public telephone lines and the Internet, procuring to achieve the necessary quality to reach the conditions required on H323. It is certain that the top technology that allows to assure that the QoS is most demanding, are a reality. However, these technologies alone pay off practically under conditions that are not very feasible for formalizing would be of the ambient control of the laboratory. In this work we analyzed the technical problems of the telecommunications that affect the yield of the links for applications of multimedia on the Internet.
