摘要: 对传统的校园网视频直播技术架构进行了分析,针对存在的传输路径长、网络抖动影响大等不足,提出了一种基于云计算环境的视频直播设计方法。首先对基于云计算环境的视频直播整体架构进行了描述,然后对涉及的关键问题进行了深入的分析,最后在真实的校园网环境中进行了测试。该方法采用分层的建设思路,具有可弹性扩展的特点,有效地节约了校园网主干线路的大量带宽和物理计算资源,降低了视频直播平台的运行维护难度。

Abstract: This article analyzed the structure of traditional campus network live video technologies. It proposed a live video design method, based on cloud computing, to solve current shortcomings and deficiencies. The article began with a description of the whole live video structure in cloud computing environment, and then made a thorough analysis on the related key issues. Finally, a test was carried out on a real campus network. This method adopted multi-layer construction thoughts. It is flexible and expandable. It substantially saves a lot of the main campus network broadband and physical calculation resources. It reduces the difficulty in the operation and maintenance of the live video platform.

Key words: campus network , cloud computing, virtualization, live video, bandwidth
