摘要

目前大多数以实时方式播放远程视频数据的系统传输视频数据包而不重传。但是，如果播放时间延迟固定的时间，则可以重传损坏的数据包。本文提出了一种新的基于SSCOP的ATM网络可靠实时协议，该协议对在截止日之前到达接收端的唯一损坏的数据包进行重传。介绍了该协议在UNIX内核中使用STREAMS机制的实现方法及其性能评价。该协议适用于视频会议工具(vic)应用，丢包率小于1/100。

Design and implementation of reliable protocol for video data produced in real time manner

Most 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 of 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 deadline. It also describes the implementation method of the proposed protocol in the UNIX kernel using STREAMS mechanism and its performance evaluation. This protocol can be applied to vic (videoconference tool) application and reduces the packet loss rate to less than 1/100.
