Aspera-fasp技术在视频CDN系统中的应用与研究

Application and Research of Aspera-fasp Technology in Video CDN System

研究、设计了一个基于HTTP Live Streaming视频流媒体技术的视频直播和点播的CDN系统,并在此基础上对其进行优化。目前,传统的CDN系统虽适用于目前国内大部分的网络环境,但在某些极端恶劣的环境条件下,比如无专线网络情况下的跨国数据传输,还是无法满足正常的业务需求。因此,该设计引入了Aspera-fasp传输技术,这是一项突破性的传输协议,能充分利用现有的WAN基础设施和通用硬件,让其为传统的CDN系统提供全球数据的快速传输。

A CDN system for live streaming or video on demand based on the technology of HTTP Live Streaming is designed and implemented, furthermore, it improves and optimizes this system. Although traditional CDN system is suitable for most domestic network environment, but in some extreme environmental conditions, such as cross-border data transmission without dedicated network, or cannot meet the business needs. Therefore, this paper introduces the Aspera-fasp transport technology which is a breakthrough transfer protocol that leverages existing WAN infrastructure and commodity hardware to move the world ＇ s data at maximum speed for the traditional CDN system.
