Problems solved by technology

[0011] However, this solution also has disadvantages: since the multicast method requires the support of the bottom layer of the network, and the heterogeneity of the existing network has very limited support for multicast, it is necessary to continue to study multicast on the existing network. This solution is suitable for newly-built networks, and the support for multicast by each network device should be considered from the beginning of planning

specific Embodiment 1

[0102] The first step, the URL of the live channel in the existing MDN is rtsp: / / www.aaa.com / PhenixNews, then the URL of the P2P live broadcast in this system is p2p: / / www.aaa.com / PhenixNews? mode=rtsp.

[0103] Step 2: The user clicks the URL on the web page, and the associated P2P client can be automatically opened according to the "p2p: / / " client operating system, and the P2P client changes the URL to rtsp: / / www.aaa.com / PhenixNews? Initiate a live channel request after mode=p2p.

[0104] In the third step, MDN redirects the request to the SLB of the edge node that provides PhenixNews.

[0105] In the fourth step, the SLB judges that this is a P2P request according to the URL parameter mode=p2p in the request, so it redirects to the Tracker of the edge node. At this time, the URL that Tracker receives the request is rtsp: / / tracker's IP / PhenixNews? mode=p2p.

[0106] Step 5. Tracker searches the stored live channel information according to the live channel ID ("PhenixNews...

[0109] The first step, the URL of the live channel in the existing MDN is rtsp: / / www.aaa.com / PhenixNews.

[0110] In the second step, the user clicks the URL on the web page, and by associating the P2P client with "rtsp: / / ", the client operating system can automatically open the P2P client. The client requests this URL via standard RTSP.

[0111] Step 3: MDN redirects user requests to the SLB that provides PhenixNews.

[0112] Step 4: The P2P client requests the URL from the SLB, as follows:

[0113] RTSP SETUP rtsp: / / 202.83.8.1 / PhenixNews RTSP / 1.0 / / 202.83.8.1 is the IP address of SLB

Abstract

The invention relates to a system for realizing direct broadcast in media distribution network MDN, relative method and client, wherein said method comprises: A, point-to-point client sends direct broadcast program request to GSLB, said request is directed to the SLB of edge node, then to be directed to the node gateway controller; B, node gateway controller based on stored direct broadcast program information, fixes the point-to-point media service gateway of video direct broadcast data of other points in said request to other point-to-point client or / and built gateway that stores the video direct broadcast data, to send the address of said gateways to the point-to-point client; C, the client selects at least one address to connect, and receives the video direct broadcast data sent from other clients or / and gateways.

Description

technical field [0001] The invention relates to the technology of video transmission in the media distribution network, in particular to a system, method and client end for realizing live video in the media distribution network. Background technique [0002] With the development of the Internet, users pay more attention to the browsing speed and effect of websites when using the Internet. However, due to the surge in the number of users, the network access path is too long, which seriously affects the quality of user access. Especially when the link between the user and the website is congested by a sudden large flow of data, poor access quality is an urgent problem to be solved for areas where Internet users in different places increase rapidly. How can we enable users from all over the world to have high-quality visits, and minimize the resulting costs and website management pressure? Content Delivery Network (CDN, Content Delivery Network) appeared. [0003] By adding a...
