Stream media service system based on controllable P2P technology and realizing method thereof

Abstract

A service system of stream media based on controllable P2P technique comprises bureau center, sub center, client end and network connected with three said units on sense of space or service providing layer, service support layer and network transmission layer on sense of logical function. Its realizing method utilizes dispatch server to control P2 P transmission between client ends according to control policy.

Description

technical field [0001] The invention relates to a streaming media service system and an implementation method for realizing distributed storage and controllable P2P (Peer to Peer, peer-to-peer) technology on a network based on the TCP / IP protocol, and belongs to the technical field of streaming media in computer networks. Background technique [0002] Streaming media refers to continuous time-based media using streaming technology in the Internet / Intranet, and refers to the ability to transmit video, audio, and presentations like PowerPoint. These streaming contents can be downloaded and played at the same time, so they are generally welcomed by users, such as multimedia news releases, online live broadcasts, online video advertisements, e-commerce, video on demand, distance education, Internet radio, real-time video conferences and other streaming media in The application on the Internet is very extensive. With the popularity of broadband networks and the advancement of vi...

AI Technical Summary

Problems solved by technology

[0004] 1. The capacity of the server is limited. With the increase of the number of users, the operator must increase the number of servers, which increases the investment;

[0005] 2. The centralized setting of the streaming media server group will bring great pressure to the network outlet of the central computer room when there are a large number of online users at the same time, resulting in performance bottlenecks;

[0006] 3. The scalability of the server capacity is limited. The system designed according to the usual situation, under some special circumstances (such as the live broadcast of ball games, sports games, theatrical performances, spacecraft launches, etc.), the intensive burst requests of users will make the server and network exit unbearable. Heavy load, difficult to meet user requirements

However, these systems usually can only provide live broadcast services and cannot provide on-demand services that users are more interested in. Even if a few systems claim to support on-demand services, they are buffered due to over-reliance on point-to-point transmission between clients and lack of effective control. The time is too long, the QoS (Quality of Service, quality of service) cannot be guaranteed, and has not been recognized by users in practical applications; moreover, this type of system does not support VCR functions such as pause, forward, backward, and drag of the movie.
