| 摘 要： | 数据报丢失控制是在因特网中传输视频时的基本问题,缓冲区管理是防止视频数据报丢失的传统网络技术.为了解决视频通信中数据报丢失的问题,提出了一种新的分组调度方法,并建立视频通信系统环境,进行了编程实验.对运行在路由器内,能够保证视频传过程中视频流内部和视频流之间数据报丢失要求的分组调度方法进行了仿真和分析.结果表明了该分组调度方法在控制数据报丢失和效率方面的优点.

| Abstract: | Packet loss control is an essential issue for video transportation over Internet.Buffer management is a traditional network technique to protect video data against packet loss.A new innovative use of packet scheduling to meet the loss constraints of video com-munication is proposed.Followed by programming tests concerning establishment of systematic video communications,the packet-scheduling scheme at a router is simulated and evaluated using real video data which assures that intra and inter-stream loss re... |
