Overview

Real-Time Streaming (RTS) is a leading interactive streaming feature that Alibaba Cloud developed based on the User Datagram Protocol (UDP). RTS uses Web Real-Time Communication (WebRTC) to transfer data. RTS relies on ApsaraVideo Live and leverages the various Content Delivery Network (CDN) nodes and network resources of Alibaba Cloud CDN worldwide. RTS supports tens of millions of concurrent streams and a maximum end-to-end latency of two seconds while minimizing your deployment costs. Livestreaming has become popular in various commercial fields. To provide an excellent livestreaming user experience, you must have robust technology and resource support. RTS was developed by Alibaba Cloud based on its practical experience. RTS helped with Taobao’s livestreaming during the Double 11 Global Shopping Festival.
