Problems solved by technology

[0005] However, the above method will cause the user to watch the delay time of real-time video to increase, and the increased delay time mainly includes: the time required for buffering streaming media data and saving it as a video file data block (for example, saving a video file with a duration of 5s data block, it takes at least 5 seconds); after saving it as a video file data block, notify the CDN control center to let it know that the video file data block has been saved, and can synchronize the time required; the CDN control center notifies the viewing server to start synchronizing all time needed; watch the time it takes for the server to sync video file chunks, etc.
For live streaming, excessive latency can severely impact user experience

Embodiment 1

[0021] A method for transmitting real-time streaming media data is provided in this embodiment, and the method is applied to such as figure 1 In the CND network shown in , the CDN network includes a CDN network of communication-connected publishing servers, transit servers, and viewing servers. Each region that requires CDN acceleration will deploy several publishing servers and several viewing servers; for example, figure 1 Central area D is composed of a publishing server and a viewing server; area C is composed of a publishing server and two viewing servers; it should be noted that although the distance of the transit server in the figure is relatively close, the actual network transit server It is not necessarily deployed in a centralized manner, but is deployed in different regions and in the computer rooms of different operators according to the network quality.

Embodiment 2

[0031] In this embodiment, when the viewing server selects a relay server or a publishing server, it can choose the one with better service quality for data transmission; the good service quality in this embodiment mainly means that the data transmission speed to the viewing server is fast. In order to further optimize the quality of data transmission, this embodiment also provides a method for the viewing server to select a transfer server or a publishing server during the data transmission process implemented by the method provided in Embodiment 1.

[0032]Since the network conditions between servers located in the same area are generally good, therefore, in this embodiment, when there is a publishing server publishing the target stream media data in the area where the viewing server is located, the viewing server directly publishes the target streaming data in this area. A distribution server of media data requests the target streaming media data. that is, Figure 7 as sho...

Abstract

The invention provides a real-time streaming media data transmission method. The real-time streaming media data transmission method is applied to a CDN formed by connecting a publishing server, a transit server and a watching server in a communication mode. The method comprises the steps that the publishing server receives streaming media data published by a client terminal of a publisher; when the publishing server, the transit server and the watching server receive streaming data requests, and target streaming media data are forwarded to a requester if the target streaming media data exist locally. According to the real-time streaming media data transmission method, a user can quickly obtain real-time streaming media data for playing, and the delay time of real-time streaming media transmission is effectively shortened.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a real-time streaming media data transmission method. Background technique [0002] With the rapid development of the Internet in recent years, CDN technology provides strong support for a large number of users to quickly access Web pages and update page form data. CDN technology refers to the placement of node servers throughout the network, thereby forming a layer of intelligent virtual network architecture on the basis of the existing Internet. Through CDN technology, the content of the website can be released to the network "edge" closest to the user, so that the user can obtain the required content nearby, thereby improving the response speed of the user's access to the website and improving the user experience. [0003] Streaming transmission refers to the form of transmitting audio, video and multimedia files in the network in a streaming manner. The stream...
