摘要
网络计算机是新一代的计算模式,该文提出并实现了一种基于共享虚拟设备的网络音频传输模型,为网络计算机提供多媒体扩展。通过RAB协议传输音频流,端到端链路带宽测量、自适应编码和分布式实时传输控制为网络音频流提供QoS支持。
Network computer is next generation computing model,a model of networking audio transport based on shared virtual device is proposed and implemented in this paper,and extends multimedia feature for network computer.Audio streams are transported via RAB protocol,end-to-end available bandwidth measurement ,self-adaptive encodings and distributed control for real-time transport supports QoS of audio stream transport.
