System and method for realizing streaming media content service

Abstract

The invention discloses a system and a method for realizing streaming media content services. The invention combines P2P technique with CDN technique, connects a plurality of physical network administrative domains through communication networks and adopts constructing P2P network topology on EMSs in the domains. A DTS is also arranged in the domain, stores all storage content information of the EMSs in the domain and can fast find out the EMS storing certain media content when the searching delay of a DHT is larger. Besides, the DTS stores the information of cross-domain media content, and can fast locate the request to other domains when the media content requested by a user can not be found out in the domain. On one hand, the adoption of the invention resolves the poor expandability problem of the CDN system media capacity and user scale and reduces the effects of the bandwidth and the single point failure of a center node on other nodes in the system; and on the other hand, the arrangement of concentrative catalog servers guarantees the search time of nodes and ensures service quality.

Description

technical field [0001] The invention relates to a distributed streaming media content service system and method, which provides various streaming media content services including live streaming, on-demand broadcasting, carousel broadcasting, and downloading for clients such as computers, media consoles, and video phones. Background technique [0002] In recent years, streaming media content services are in a stage of rapid development, with storage capacity reaching hundreds of terabytes, or even thousands of terabytes, and user scale expanding from tens of thousands to millions, or even tens of millions. Although the traditional CDN (Content Delivery Network) technology can accelerate streaming media distribution to a certain extent and realize services such as live broadcast, on-demand, carousel, and download, its core is still based on a centralized server structure, mainly including the following: question: [0003] (1) When the media content increases, the capacity of ...

AI Technical Summary

Problems solved by technology

[0003] (1) When the media content increases, the capacity of each node needs to be increased accordingly, and the scalability of the media capacity is poor;

[0004] (2) When the number of users increases, the CPU processing power, reading and writing capabilities of each node need to be strengthened synchronously, and the scalability of the user scale is poor;

[0005] (3) The network bandwidth consumption of the central node is large, and the reliability caused by single point failure is poor, etc.

[0006] Due to the above problems in traditional CDN technology, it cannot meet the needs of large-scale video content and users
