چکیده

Most of current systems which play video data produced remotely in a real time manner transfer video packets without retransmission. However, corrupted packets can be retransmitted if the time of playing is delayed for the fixed amount time. This paper proposes a new reliable real time protocol, based on SSCOP for ATM networks, which retransmits the only corrupted packets which reach the receiver before the dead line. It also describes the implementation method of the proposed protocol in UNIX kernel using STREAMS mechanism and its performance evaluation. This protocol can be applied to vic (video conference tool) application and reduce the packet loss rate to less than 1/100.
