摘要

本文描述了一种用于卫星实时IP多播音频视频流地面中继的体系结构。这种中继是由配备有卫星接收器和地面互联网链路的节点执行的。没有配备卫星接收硬件但仍然愿意接收的站点请求和获取流。通过利用卫星传输的特性和采用混合卫星/地面、多播/单播方法,所描述的架构允许克服全球互联网中多播流量所遭受的限制,使其能够轻松地跨自治系统进行扩展。

CHARMS: Cooperative hybrid architecture for relaying multicast satellite streams to sites without a satellite receiver
This paper describes an architecture dedicated to the terrestrial relaying of a real-time IP multicast audio-video stream broadcasted by a satellite. Such relaying is performed by nodes equipped with both a satellite receiver and a terrestrial Internet link. The stream is requested and obtained by sites that are not equipped with satellite receiving hardware but are nonetheless willing to receive it. By exploiting the properties of satellite transmission and adopting an hybrid satellite/terrestrial, multicast/unicast approach the described architecture allows to overcome the restrictions suffered by multicast traffic in the global Internet, allowing it to scale easily across autonomous systems.
