摘要 通过高速网络传输视频已被广泛关注,但视频的存储量较大,为防止网络拥塞,应采取一系列有效的策略来解决视频传输问题。文章介绍了基于代理缓存技术的视频传输策略:代理前缀缓存、基于段的代理缓存、视频切分技术和中介等。从不同侧面解决视频传输过程中的拥塞问题,以保证良好的视频传输。 Video delivery by high speed wide-area network has been widely concerned, but storage capacity of video is much higher, in order to prevent congestion of network, we should adopt a series of effective schemes to solve video delivery problem. In this article we introduce video delivery methods about proxy caching technology such as proxy prefix caching, segment-based proxy caching, video-staging and middleman. These schemes resolve congestion problem in video delivery procedure from different facets, in order to ensure better video delivery.
