Embodiment 1

[0104] Such as Picture 11 As shown, when the terminal uses the HTTP protocol to access the service node (in the case of a service node miss), the specific implementation process is as follows:

[0105] The terminal (which can be a user terminal) initiates a DNS request to a local (Local) Domain Name System (Domain Name Syterm, DNS) server;

[0106] Local DNS initiates a domain name resolution request to the SP authorized DNS;

[0107] SP authorizes DNS to respond to LocalDNS's alias of the domain name in the form of alias (CNAME);

[0108] LocalDNS initiates a domain name resolution request for the alias;

[0109] The global scheduling module returns the best service node address as the analysis result;

[0110] Local DNS responds to user terminal requests;

[0111] The user terminal initiates an HTTP GET request to the service node;

[0112] The service node selects the most suitable server according to a certain strategy;

[0113] The user terminal initiates an HTTP GET request to the ad...

Embodiment 2

[0117] Such as Picture 12 As shown, when the terminal uses the HTTP protocol to access the service node (in the case of a service node hit), the specific implementation process is as follows:

[0118] The terminal (which can be a user terminal) initiates a DNS request to the LocalDNS server;

[0119] LocalDNS initiates a domain name resolution request to the SP authorized DNS;

[0120] SP authorizes DNS to respond to LocalDNS's alias of the domain name in the form of CNAME;

[0121] LocalDNS initiates a domain name resolution request for the alias;

[0122] The global scheduling module returns the best service node address as the analysis result;

[0123] LocalDNS responds to user terminal requests;

[0124] The user terminal initiates an HTTP GET request to the service node;

[0125] The service node selects the most suitable server according to a certain strategy;

[0126] The user terminal initiates an HTTP GET request to the address returned by the service node;

[0127] The server obta...

Embodiment 3

[0130] Such as Figure 13 As shown, when the terminal uses the RTSP protocol to access the service node (in the case of a service node miss), the specific implementation process is as follows:

[0131] The terminal (which can be a user terminal) initiates a DNS request to the Local DNS server;

[0132] Local DNS initiates a domain name resolution request to the SP authorized DNS;

[0133] SP authorizes DNS to respond to LocalDNS's alias of the domain name in the form of CNAME;

[0134] Local DNS initiates a domain name resolution request for the alias;

[0135] The global scheduling module returns the best service node address as the analysis result;

[0136] Local DNS responds to user terminal requests;

[0137] The user terminal initiates an RTSP DESCRIBE request to the service node;

[0138] The service node selects the most suitable server according to a certain strategy;

[0139] The user terminal resends the RTSP DESCRIBE request to the new server address returned by the service node;...

Abstract

The embodiment of the invention provides a method, equipment and a system for multimedia content distribution. The method includes allowing service nodes to receive a request sent by a terminal and acquire a visit requirement of a first media content; allowing the service nodes to identify the type of the terminal, match a second media content matching with the terminal in types and return to the terminal from each media content stored locally according to the identified type. Each media content stored locally by the service nodes is information, configured by the service nodes according to media content and acquired through multi-format conversion of each original content sent by a CDN content center or acquired from the service nodes transmitted by the CDN content center after multi-format conversion of each original content is performed by the CDN content center according to the media content configured information. By the aid of the method, the equipment and the system, the problems that the existing service is high in computing pressure and storing pressure and low in operating efficiency are solved, and the problems that the media content sent by the service nodes cannot be played and watched normally since the media content cannot match with the terminal in types are avoided.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, and in particular to a multimedia content distribution method, equipment and system. Background technique [0002] Multimedia services have now become the main traffic component of the Internet. For example, video-on-demand websites and video UGC websites account for more than 80% of the traffic. However, due to the huge amount of video content data, almost all Internet video websites adopt self-built methods or The rental method uses the content distribution system CDN as its basic transmission network to distribute video content to the edge of the network, so that the terminal can quickly access the on-demand or live content provided by the website. [0003] At present, the following methods are generally adopted for the distribution of the above-mentioned multimedia content: the business system performs multiple encoding processes on each original media content (for example, vid...
