Abstract

The invention provides a streaming media transmission method, device and system, relating to the field of Internet transmission, and aiming at solving the problem that response processing is carried out after the network has performance problems and failures and the data transmission interruption or delay is caused. The method comprises the following steps: when a subordinate node requests to playstream information, allocating at least two superior nodes to the subordinate node as objects for requesting to play a stream according to monitoring data of the link quality between each superior node and the subordinate node; sending an upstream superior node list including the at least two superior nodes allocated to the subordinate node to the subordinate node, and indicating the subordinatenode to perform data backtracking on the superior nodes through part or all of the superior nodes in the upstream superior node list. The technical scheme provided by the invention is applicable to adata stream publishing network with a multi-level structure, and ensures that the continuous transmission of streaming data can be achieved without being affected by network fluctuations.

Description

technical field [0001] The invention relates to the field of Internet transmission, in particular to a streaming media transmission method, device and system. Background technique [0002] In the live broadcast distribution scenario, the edge-parent-source 3-level architecture is generally adopted, and the live stream is pushed to the source station, usually using the RTMP protocol, and the audience pulls the ball from the edge node to watch the live stream. The viewing protocol includes rtmp / http-flv / hls. RTMP has been phased out in streaming scenarios due to the complexity of the protocol interaction. Due to the large delay of live streaming, hls has limited application scenarios. At present, the http-flv protocol is mainly used to pull live streams. [0003] Data transmission between the edge-parent-source levels is carried out through the public network. The public network often has network congestion, routing failures, and routing flashes, which lead to a large number...
