Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In general, a public cloud refers to a distributed streaming media distribution server built based on a standard protocol RTMP.
In practical application, the public cloud can only access the RTMP upstream. When the user is in live broadcasting, the live broadcasting application program is used for pushing stream to request system scheduling. The system can distribute the edge nodes of the corresponding operators to receive the live broadcast stream after receiving the request, then the edge nodes transfer to the father layer nodes, and then the father layer nodes further transfer to the super father layer nodes.
Because the push flow is performed by a certain operator, in order to enable users of other operators to receive and watch the live broadcast flow, the super parent layer node of the operator which is distributed nearby actively pushes the flow to the super parent layer nodes of all operators, and even if no user watches the live broadcast, the super parent layer node continues to push to all the parent layer nodes after receiving the push flow.
When watching the live broadcast, the user needs to access the system schedule first, return to the nearby edge node by the system schedule, and then return to the source parent layer node by the edge node to complete the watching of the live broadcast.
Since the public cloud can only support the standard-included RTMP upstream for distribution, the data stream is transmitted based on the TCP protocol during distribution, and each node is required to be unpacked and packaged again. And the delay of watching the live broadcast by the user is increased by about 2 seconds every time the live broadcast passes through one layer of nodes.
The private cloud is a distribution server built according to a certain private protocol used by a live application provider, and is a ring-shaped live distribution system. The private cloud adopts the private protocol to distribute and transmit data streams, only live broadcast application programs corresponding to the SDK integrated with the private protocol can be watched, and compared with the public cloud, the private cloud is not open enough, and access of users is limited.
However, the private cloud can only access the data stream in the private protocol format and can transmit the data stream based on the UDP, so that transparent transmission between the nodes can be realized during transmission, and the delay is relatively low.
Therefore, based on the respective advantages and disadvantages of the public cloud and the private cloud, the core concept of the embodiment of the invention is that the public cloud accesses the service to the outside and the private cloud distributes the internal data stream, so that the distribution speed of the data stream is increased and the number of accessible users is increased.
Referring to fig. 1, a schematic flow chart illustrating steps of a video live broadcasting method according to an embodiment of the present invention specifically includes the following steps:
101, a public cloud parent layer node receives a current live broadcast stream pushed by a public cloud edge node;
in the embodiment of the invention, the service can be accessed to the outside through the public cloud. Namely, each live application program is accessed to the public cloud, and the number of accessible users is increased through the public cloud.
In the embodiment of the invention, when the user is in live broadcasting, the live broadcast stream of the current live broadcast can be collected and pushed to the nearby public cloud edge node through the live broadcast application program.
In specific implementation, when a live broadcast application program pushes a live broadcast stream, a nearby public cloud edge node can be automatically identified according to a network topology structure, and then the live broadcast stream is pushed to the edge node.
After the public cloud edge node receives the live stream, the live stream can be further pushed to a public cloud parent layer node.
In a particular implementation, different live streams may have respective marking information. When the public cloud edge node pushes the stream to the public cloud parent layer node, the same live stream can be pushed to the same parent layer node according to the marking information, and therefore repeated stream pushing is avoided.
And 102, the public cloud parent layer node pushes the live stream to a private cloud server, and the private cloud server is used for distributing the live stream to a plurality of playing terminals.
In the embodiment of the present invention, in order to increase the distribution speed of the live stream, the distribution of the live stream may be performed by a private cloud.
Therefore, after the public cloud parent layer node receives the live stream forwarded and pushed by the edge node, the live stream can be pushed to the private cloud, and the private cloud performs subsequent distribution on the live stream.
In the embodiment of the invention, by connecting the public cloud and the private cloud, when in live broadcasting, the public cloud parent layer node can receive the live broadcast stream pushed by the public cloud edge node and push the live broadcast stream to the private cloud server, so that the public cloud super parent layer node does not need to actively push the stream to the parent layer node, and the bandwidth of the server is saved; according to the embodiment, the private cloud server is used for distributing the live stream, the live stream can be transparently transmitted when passing through each node during distribution, the live stream does not need to be re-unpacked, the distribution speed of the live stream is increased, and the live delay is reduced.
Referring to fig. 2, a schematic flow chart illustrating steps of another video live broadcasting method according to an embodiment of the present invention is shown, which may specifically include the following steps:
in the embodiment of the invention, the service can be accessed to the outside through the public cloud. Namely, each live application program is accessed to the public cloud, and the number of accessible users is increased through the public cloud.
In the embodiment of the invention, the current live broadcast stream can be formed by encoding audio data and/or video data collected by a recording terminal accessed to a public cloud edge node.
Fig. 3 is a schematic business flow diagram of another video live broadcasting method according to an embodiment of the present invention. In fig. 3, after receiving a live stream pushed by a recording terminal, a public cloud edge node may push the live stream to a public cloud parent layer node.
In order to ensure that the live stream can be pushed to the same parent layer node, the public cloud edge node can identify which parent layer node the current live stream is pushed to through the marking information of the live stream, so that the subsequent live stream of the live stream is still pushed to the parent layer node, and repeated pushing is avoided.
in the embodiment of the present invention, in order to increase the distribution speed of the live stream, the distribution of the live stream may be performed by a private cloud.
Therefore, in the embodiment of the present invention, after receiving the live stream pushed by the edge node, the public cloud parent layer node may first determine to which private cloud server the live stream should be forwarded.
in the embodiment of the invention, after the public cloud parent layer node determines the target private cloud server of the specific live stream, the live stream can be pushed to the target private cloud server, and the target private cloud server receiving the live stream distributes the live stream so as to push the live stream to each playing terminal watching the current live stream.
in the embodiment of the invention, when the public cloud parent layer node pushes the stream to the private cloud server for distribution, the live stream can be pushed to the public cloud super parent layer node for backup. Therefore, when the private cloud server breaks down, the live streaming backed up at the public cloud super parent layer node can be pulled and distributed to the plurality of playing terminals, and the smooth proceeding of the live streaming is ensured.
In the embodiment of the invention, the public cloud parent layer node can also push the live stream to a preset service platform, and the operations of transcoding, recording and playback and the like are carried out on the platform.
In the embodiment of the invention, the connection between the public cloud and the private cloud is opened, so that live streaming can be carried out, the public cloud parent layer node pushes the live streaming to the private cloud server, and the private cloud server carries out distribution of the live streaming, thereby accelerating the distribution speed of the live streaming and reducing the live streaming delay.
Secondly, when the live stream is pushed to the private cloud server to be distributed, the public cloud parent layer node can also push the live stream to the public cloud super parent layer node to be backed up, once the private cloud server breaks down, the backed-up live stream can be timely pulled from the super parent layer node, and the smooth proceeding of the live broadcast service is ensured.
Referring to fig. 4, a schematic flow chart illustrating steps of another video live broadcasting method according to an embodiment of the present invention specifically includes the following steps:
in the embodiment of the invention, when a user wants to watch the live broadcast, the instruction for watching the live broadcast can be sent to the playing terminal, the playing terminal can forward the instruction to the nearby public cloud edge node, and then the public cloud edge node forwards the instruction to the public cloud parent layer node again.
Fig. 5 is a schematic business flow diagram of another video live broadcasting method according to an embodiment of the present invention. In fig. 5, after the public cloud parent layer node receives the instruction of watching the live broadcast, source data can be returned from the private cloud server to obtain a live broadcast stream that the user wants to watch.
It should be noted that when the source data return from the private cloud server by the public cloud parent layer node fails, the source data can be returned from the public cloud super parent layer node to obtain the live broadcast stream. The live stream at the public cloud super parent layer node can be obtained by pushing a parent layer node corresponding to a live recording terminal side to the super parent layer node for live stream backup when live broadcasting is carried out.
in the embodiment of the invention, after the source data is returned, the public cloud parent layer node can push the live stream to the public cloud edge node, and the edge node further pushes the live stream to each playing terminal, so that the playing terminals can receive the live stream in time.
In the embodiment of the invention, by connecting the public cloud and the private cloud, when watching the live broadcast, the public cloud parent layer node can return source data from the private cloud server to obtain the corresponding live broadcast stream, thereby improving the distribution speed of the live broadcast stream and reducing the live broadcast delay.
