The edge ingest feature preferentially ingests video streams to the optimal CDN node to ensure that users can access the optimal uplink network. This also minimizes the negative impact of problems such as video lagging and slow stream-pulling ratio caused by slow uplink transmission.
Wide coverage: ApsaraVideo Live has over 1,500 CDN nodes around the world, including over 700 nodes in mainland China, covering most mainstream cities and regions.
Stream acceleration is designed to create a high-quality network transmission path between the video capture region and the playback source station. This allows videos to be transmitted by using the shortest and optimal path between the video capture and playback regions, and eliminates the problems of video lagging and high latency.
Low-cost access: Stream acceleration supports access in a highly flexible way. No development and server purchase costs are needed. This feature is enabled immediately after the configuration is completed.
High speed and stability: Stream acceleration supports access and distribution from the nearest edge node. Global nodes are connected through high-speed lines.
Global coverage: Mainstream regions such as Asia, Europe, and America are covered.
Flexible billing: To meet different user needs, the service is billed on a daily basis and supports the configuration of transmission networks at the stream level.
|Comparison item||Public network transmission||Stream acceleration|
|Communication quality and availability||The quality of long-distance public network communication is affected by a variety of factors. It is difficult to guarantee low latency, high stability, and a low packet loss rate.||The high-quality infrastructure of Alibaba Cloud guarantees enhanced path quality and higher availability.|
|Costs||Public network transmission is billed in Pay-As-You-Go mode.||No hardware cost is required. The billing methods are flexible and the price is affordable.|
