Stream media acceleration system, method and device based on content distribution network

Abstract

The embodiment of the invention discloses a streaming media accelerating system based on a content delivery network (CDN), which relates to the streaming media application field and is used for solving the problem of the poor reliability of a streaming media accelerating proposal of the CDN in the prior art. The system comprises top-layer streaming media accelerating equipment and underlayer streaming media accelerating equipment; the top-layer streaming media accelerating equipment is used for receiving a streaming media acquire request from the underlayer streaming media accelerating equipment, acquiring streaming media data from a data source station or other streaming media accelerating equipment of the top layer and sending the acquired streaming media data to the underlayer streaming media accelerating equipment; the underlayer streaming media accelerating equipment is used for receiving a streaming media acquire request from a user, acquiring the streaming media data from the top-layer streaming media accelerating equipment or other streaming media accelerating equipment of the underlayer and sending the acquired streaming media data to the user. The embodiment of the invention also discloses a streaming media transmission method based on the streaming media accelerating system and streaming media accelerating equipment. The invention is adopted to greatly improve the reliability of the streaming media accelerating system.

Description

technical field [0001] The invention relates to the field of streaming media applications, in particular to a streaming media acceleration system, method and device based on a content distribution network. Background technique [0002] With the popularity of broadband, streaming media applications have developed rapidly. Traditionally, streaming media services are directly provided by Internet Content Providers (ICPs). Specifically, ICPs establish physical nodes (ICP sites) in one or a few places, and the physical nodes directly provide services to Internet users across the country and even around the world. Streaming services, that is, all Internet users get streaming data from these physical nodes. [0003] The above-mentioned problem of directly providing streaming media services by ICP is that the number of physical sites deployed by ICP is very limited, and the service bandwidth of each physical node is also limited. When a large number of users access physical sites a...
