| Abstract(in English) | This report studies the transmission of audio-video streams and data flows with the AF service of DiffServ by experiment. How the transport protocols (UDP and TCP) of the data flows affect media synchronization quality in this situation has not been clarified so far. In our experiment, we deal with two pairs of audio-video streams and two data flows, i.e., a TCP flow and a UDP one. By changing AFCP of the TCP data flow and the load of the UDP one, we measure the intra-stream and inter-stream media synchronization quality. We then find that it is effective to assign the TCP data flow to the same class as that of the video flow from a media synchronization point of view. In this case, however, the throughput of the TCP data flow seriously deteriorates. As a solution to this problem, we propose that the TCP data flow is assigned to a distinct class which is allocated less bandwidth than the audio and video. |
