Content distribution network system and content distribution method

Abstract

The invention discloses a content distribution network system and a content distribution method. The system comprises a content distribution network (CDN) management background system, a center storage system, a resource management server and a streaming server. The CDN management background system offers a file pre-distribution interface so as to provide desired pre-distributed hot files for resource management. The center storage system is one of Hadoop, file transfer protocol (FTP) storage or network attached storage (NAS). The resource management server has a resource management service and a memory database. Each streaming area of the streaming server has a streaming Web service. The content distribution method is carried out based on the system. Compared with the prior art, the content distribution network system and content distribution method can distribute hot files to streaming nodes, save the streaming storage cost, lower network bandwidth between the center and storage nodes, have high practicability, can be widely used, and are easy to promote.

Description

technical field [0001] The invention relates to the technical field of communication information, in particular to a highly practical content distribution network system and method. Background technique [0002] For common video-on-demand and live broadcast playback systems, such as video-on-demand playback systems at the city or provincial level, its streaming nodes usually have the following characteristics: a large number of video-on-demand users, scattered areas, central storage Channels that cannot satisfy all users’ on-demand requests, or cannot withstand the concurrency pressure of all users’ simultaneous on-demand requests; when using streaming sub-nodes, the storage space of streaming nodes hopes to reduce costs and reduce disk costs; between the central node and streaming nodes The backbone network bandwidth is limited. Based on this, a content distribution network system and method are now provided. The present invention realizes the distribution of popular files...
