Problems solved by technology

[0004] In the prior art, the multicast capability is not open to OTT operators. When a large number of users watch the live channel of the same content, since only unicast transmission can be used, the CDN node needs to distribute a data stream to each user, so , CDN nodes need to consume a lot of network bandwidth and outflow load

Embodiment 1

[0078] Example 1, please refer to figure 2 , when there is only one multicast resource management server, an embodiment of the multicast implementation method in the embodiment of the present application includes:

[0079] 201. The live broadcast service server sends a multicast resource allocation request to the operator's multicast service gateway, and the operator's multicast service gateway forwards the multicast resource allocation request to the multicast resource management server, wherein the multicast resource allocation request Include the channel ID in .

[0080] In this embodiment, the live broadcast service server sends a multicast resource allocation request to the operator's multicast service gateway, and the operator's multicast service gateway forwards the multicast resource allocation request to the multicast resource management server, wherein the multicast The resource allocation request includes a channel ID. In addition, the multicast resource allocatio...

Embodiment 2

[0133] Example 2, please refer to image 3 When there is only one multicast resource management server, an embodiment of the multicast implementation method in the embodiment of the present application includes:

[0134] 301. The live broadcast service server sends a multicast resource allocation request to the operator's multicast service gateway, and the operator's multicast service gateway forwards the multicast resource allocation request to the multicast resource management server, wherein the multicast resource allocation request Include the channel ID in .

[0135] In this embodiment, this step is similar to the above step 201, which will not be repeated here.

[0136] 302. The multicast resource management server allocates a multicast IP and a live stream injection node address to the channel identifier according to the multicast resource allocation request.

[0137] In this embodiment, after the multicast resource management server receives the multicast resource al...

Embodiment 3

[0153] Embodiment three, please refer to Figure 4 , when there are two multicast resource management servers, another embodiment of the multicast implementation method in the embodiment of the present application includes:

[0154] 401. The live broadcast service server sends a multicast resource allocation request 1 to the operator 1 multicast service gateway, and the operator 1 multicast service gateway forwards the multicast resource allocation request 1 to the multicast resource management server 1, wherein the The multicast resource allocation request 1 includes a channel identifier.

[0155] 402. The multicast resource management server 1 allocates the multicast IP1 to the channel identifier according to the multicast resource allocation request 1.

[0156] 403. The multicast resource management server 1 sends a multicast resource allocation response 1 to the operator 1 multicast service gateway, and the operator 1 multicast service gateway forwards the multicast resou...

Abstract

Embodiments of the application disclose a multicast realizing method and relevant network equipment, used for reducing the network bandwidth and the out-stream load of a live stream in the network transmission process. The method provided by the embodiments of the application comprises: a live service server sends a live stream injection request to a multicast resource management server; the liveservice server receives a live stream injection response sent by the multicast resource management server; the live service server sends, according to the address of a live stream injection node, a live stream injection instruction to the live stream injection node; the live service server receives a pushed stream address sent by the live stream injection node; and the live service server notifiesa live source of sending, according to the pushed stream address, a live stream to the live stream injection node, such that the live stream injection node corresponding to the pushed stream addressuses the multicast IP to carry out multicast for the live stream.

Description

technical field [0001] The present application relates to the field of the Internet, in particular to a method for implementing multicast and related network equipment. Background technique [0002] In the Internet Protocol Television (IPTV) business carried out by telecom operators, there are three commonly used IP network data transmission methods: 1. unicast transmission, 2. broadcast transmission, and 3. multicast transmission. Among them, multicast transmission It has the advantages of high efficiency and low network bandwidth, so it is widely used, unicast transmission mode. [0003] Since the current network multicast capability is not open to Internet application (Over The Top, OTT) operators, the existing OTT live broadcast services are all implemented using unicast transmission. The mainstream solution is to transmit video resources for users closest to the CDN node by establishing a content delivery network (Content Delivery Network, CDN) node. [0004] In the p...
