一种基于云存储的 VOD 系统

摘要

针对VOD视频点播系统在高并发网络访问情况下的I/O瓶颈、网络拥塞等问题，提出一种基于云存储的解决方案。在VOD现有架构的基础上，采用云存储和CDN网络提供存储和访问服务，提高了系统的高并发访问负载能力。同时针对VOD视频转码模块提出一种基于FFMPEG的整体解决方案，能在实际应用中有效降低技术难度和开发成本，对VOD系统的优化和提升具有实际意义和应用价值。%For VOD system’ s I/O bottlenecks and network congestion problems under conditions of high concurrent network ac -cess, this paper presents a new solution based on cloud storage .On the basis of the structure on VOD , the solution uses cloud storage and CDN to provide storage service and network access service , improving the load capacity for high concurrent access to the system.While for VOD video transcode module , this paper presents a whole solution based on FFMPEG , which can reduce development costs and technical difficulties in the practical application .It has practical significance and application value for VOD system’ s upgrading and optimization .
