Embodiment 1

[0023] refer to figure 1 , which shows a structural block diagram of an embodiment of a data live broadcast system of the present invention, which may specifically include the following modules:

[0024] The data live broadcast system includes: a live data source server 101 and a cache server 102 . The data live broadcast system can distribute and live broadcast video and other data content based on the TCP / IP network.

[0025] The data live broadcast system uses the live data source server 101 as a root node and the cache server 102 as child nodes to form a tree topology structure, and the tree topology structure includes multiple levels of child nodes. Therefore, the distribution link of the live content in the data live broadcast system forms a tree structure, with the live data source server as the root, the cache server in the computer room close to the data source as the trunk, and the cache server in the computer room close to the user as the branch, and This forms a ...

Embodiment 2

[0051] On the basis of the above embodiments, this embodiment further discusses the data live broadcast system and its live broadcast method.

[0052] In the data live broadcast system of the tree topology structure, the live data source server 101 is directly connected to the first-level cache servers through a wide area network or Ethernet; the first-level cache servers are connected to each other through Ethernet; The same upper-level cache server and the same-level cache servers are connected to each other through Ethernet; the cache server and its upper-level cache server are connected through a wide area network.

[0053] Among them, since the data live broadcast system provides live broadcast functions for users in different regions, cache servers can be distributed in various computer rooms in different regions, so cache servers with the same upper-level cache server and the same level and same computer room can be configured through Ethernet The servers in different c...

Abstract

The invention provides a data live broadcast system and method which aim to solve the problem that an existing live broadcast system can cause network congestion and even network paralysis easily. The data live broadcast system comprises a live broadcast data source server and cache servers, wherein the live broadcast data source server is used as a root node, the cache servers are used as child nodes, and accordingly a tree topology structure is formed. According to the system, the live broadcast data source server is used for storing live broadcast source data, the live broadcast data source server only distributes source data which require to be subjected to live broadcast to the first level of cache servers, and thus the phenomenon that congestion and paralysis happen to the live broadcast data source server due to the fact that excessive nodes are accessed simultaneously can be avoided. Under the tree topology structure, after the cache servers receive data live broadcast requests, the cache servers can sequentially request data sources towards the previous level of cache servers in a classification mode, and therefore the problem that congestion and paralysis happen due to the fact that excessive nodes are connected into all the levels of cache servers is solved. The source data which require to be subjected to live broadcast can be provided quickly, and the live broadcast quality of the source data is improved.

Description

technical field [0001] The invention relates to the technical field of data live broadcasting, in particular to a data live broadcasting system and a data live broadcasting method. Background technique [0002] Users can watch live broadcast content through the network through players, webpages, etc., such as video, graphic live broadcast, etc. Existing data live broadcast systems usually adopt a simple copy and active push mode, that is, the data of the same live stream is pushed to each Internet Data Center (IDC) node and each connected IDC node of the entire data live broadcast system. Physical machine (user terminal). [0003] Therefore, when distributing a large-scale live program with many concurrent user requests, or distributing many channels of concurrent live data content in different places, the entire live data network will be congested, and even the source data of the live broadcast will be overwhelmed by too many The network node connection is paralyzed. Co...
