Example Embodiment
[0047] Example one
[0048] See figure 1 , Is a flowchart of a live broadcast method provided in Embodiment 1 of the present invention. The method in the embodiment of the present invention may be executed by a live broadcast system implemented by hardware and / or software. The system includes: a content distribution network (CDN) node, and a main slice server and a backup slice server deployed on the CDN node.
[0049] The method includes:
[0050] 110. When obtaining the live broadcast request transmitted by the CDN node, the main slicing server slices the live stream to obtain live stream slices, and distributes the live stream slices to the CDN node.
[0051] 120. The main slice server generates the serial number of the live stream slice, and synchronizes the serial number of the live stream slice to the serial number storage library in the standby slice server.
[0052] In operation 110, the CDN node specifically transmits the live broadcast request of the player on the user side....

[0069] Example two
[0070] See figure 2 , Is a flowchart of a live broadcast method provided in Embodiment 2 of the present invention. On the basis of the above-mentioned embodiment, this embodiment provides that the serial number of a new live stream slice is generated on the standby slice server, and the serial number of the new live stream slice is synchronized to the serial number storage library in the main slice server The preferred solution afterwards.
[0071] The preferred method includes:
[0072] 210. After the failure of the main slice server is repaired, the main slice server monitors the operation status of the standby slice server.
[0073] 220. When the primary slicing service monitors that the backup slicing server is faulty, acquire the serial number of the new live stream slice in the serial number storage library of the primary slicing server, and according to the new live streaming The sequence number of the stream slice is used to slice the live stream to obt...
Example Embodiment
[0080] Example three
[0081] See image 3 , Is a schematic structural diagram of a live broadcast system provided in Embodiment 3 of the present invention. The system includes: a CDN node (not shown), and a main slice server and a backup slice server deployed on the CDN node.
[0082] The main slice server includes: a slice module (not shown) and a serial number processing module.
[0083] Wherein, the slicing module is used to slice the live stream to obtain live stream slices when the live broadcast request transmitted by the CDN node is obtained; distribute the live stream slices to the CDN node; the sequence number processing module is used to generate The serial number of the live stream slice; and synchronize the serial number of the live stream slice to the serial number repository in the standby slice server;
[0084] The standby slice server includes: a main standby monitoring switch, a slice module (not shown), and a serial number processing module.
[0085] Wherein, the a...
