Abstract
The invention provides a webcasting method and a system. According to the invention, the method is performed in this way. Through a main segmenting server deployed at a CDN node and upon obtaining the webcasting requirement transmitted from the CDN node, the method executes the segmentation and distribution of live streaming and at the same time, synchronizes and deploys the sequence numbers of the segmentations into the sequence number storage base in the backup segmenting server deployed at the CDN node. When the backup segmenting server monitors an outage in the main segmenting server, the backup segmenting server executes the segmentation and distribution of live streaming based on the latest sequence numbers contained in its sequence number storage base. This function realizes the smooth switch between the main segmenting server and the backup segmenting server deployed at the same CDN node as well as the synchronization of sequence numbers between the two. As a result, a player is capable of obtaining segmentation of live streaming next after the current segmentation, therefore ensuring a smooth playing process.
