Embodiment Construction

[0107] The system includes four parts: client, SIP server, extended media server (hereinafter referred to as EMS server), and media server (hereinafter referred to as MS server), as shown in FIG. 1 .

[0108] Our client software runs on the client, and its functions are: 1. Register client information with the SIP server, including user name and password; 2. Request programs; 3. Download programs from program sources; 4. Cache part of the programs; 5. Register the cached program information to the extended media server; 6. When the state changes, it can report its latest state to the extended media server in real time.

[0109] The SIP protocol stack runs on the SIP server to realize basic SIP server functions, including registration, proxy, addressing, routing and forwarding of data packets, etc.

[0110] The media server is the initial provider of programs and has one or more programs available for users to download. The functions it realizes mainly include: registering its...

Abstract

The invention includes programs at client end, programs at SIP server end, program for selecting peer-to-peer bodies, and programs at stream media server, which are setup at client end, SIP server, expanded media server, and stream media server in sequence. Based on SIP protocol, using P2P network, client end requests program from SIP server. The SIP server forwards the request to an expanded media server. The expanded media server selects best program source, which can be other client or a stream media server. Based on address of the program source, client end can down load program of stream media, and sends information of buffering program to the expanded media server. Client end or stream media server also can send information of changing node state to the expanded media server in order to cause refreshing database of media information. Advantages are: small time delay, small bandwidth consumption, and good audio/video effect.

Description

Technical field: [0001] The invention belongs to the field of information communication, especially Internet communication. Background technique: [0002] The Internet is a great milestone for mankind to enter the information society. As the product of the integration of computer technology and network communication technology, the Internet is gradually evolving from a general communication platform to a ubiquitous computing platform. How to effectively manage the growing huge resources on the Internet and realize "effective aggregation, reasonable distribution, independent coordination and credible sharing" of Internet resources is not only crucial for whether the Internet can become a computing platform, but also for a country's information The improvement of productivity level and international competitiveness in the era of globalization is of great strategic significance. [0003] Peer-to-peer network (P2P) is called one of the four new technologies that change the dev...
