OneDrive 和 SharePoint 中的视频的内容传递网络功能Content Delivery Network capability for videos in OneDrive and SharePoint

Microsoft Stream 现在支持 OneDrive 和 SharePoint 的内容传递网络(CDN)功能(ODSP)。Microsoft Stream now supports Content Delivery Network (CDN) capability for OneDrive and SharePoint (ODSP). 已将其添加到现有元/SPO 服务,该服务将缓存加密的媒体并从 Microsoft Edge 为客户端提供服务。It was added to the existing MeTA/SPO service, which will cache encrypted media and serve clients from Microsoft Edge.

在 CDN 航班上,ODSP 播放器将命中 CDN 终结点以检索媒体。On CDN flights, the ODSP Player will hit CDN endpoints to retrieve media. 如果媒体流尚未在本地缓存,则将从元或其他 CDN 边缘获取。If the media stream is not already cached locally, then it will be fetched from MeTA or from another CDN edge.

媒体缓存技术将由 Azure 前门(AFD)提供,并将帮助改进 Microsoft Stream 中视频的整体性能。The media caching technology will be provided by Azure Front Door (AFD) and will help improve the overall performance of videos in Microsoft Stream. AFD 使您能够生成、操作和扩展您的动态 web 应用程序和静态内容。AFD enables you to build, operate, and scale out your dynamic web application and static content.

此基于 CDN server 的功能将有益于在其整个企业网络中播放视频的所有 ODSP 客户。This CDN server-based functionality will benefit all ODSP customers that playback videos across their enterprise network.

优点Benefits

  • 改进了播放性能Improved playback performance
  • 提高了可伸缩性Increased scalability
  • 减少延迟/缓冲Reduced latency/buffering
  • 在 ODSP 服务上减少了负载/COGSReduced load/COGS on ODSP service
