detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

Referring to FIG. 1 , a flow chart of a method for transmitting a stream data according to a first embodiment of the present invention is shown.

Step 101: Receive first stream data transmitted from a first client according to a transmission path.

The method described in this embodiment of the present invention is applied to a scenario in which video stream data transmitted in a streaming manner exists.

In the embodiment of the present invention, there are multiple clients connected to the network topology, and the client and the client are connected by a transmission path, and the transmission path flows through one or more transmission nodes, so that a certain client is based on multiple transmission paths. The end is connected to several other clients.

The first client accessing the network topology may transmit the first stream data to other clients according to the pre-established transmission path. Stream data transmitted between clients can be transmitted using a Content Delivery Network (CDN).

The method in the embodiment of the present invention can be applied to multiple application scenarios, such as a live video scene, a video conference scenario, and the like. When the method in the embodiment of the present invention is applied to a live video scene, the live broadcast includes the anchor end, the guest end, and the common user end, and the first client may be the main broadcast end, and the first stream data is the video stream data transmitted by the main broadcast end.

After the user enters a live broadcast room and becomes an ordinary user, the dispatch node allocates the transmission path of the normal user to the anchor, the guest, and other common users, that is, the scheduling node adjusts the network topology of the live broadcast. Add the new normal client to the network topology. The scheduling node can allocate a transmission path for the common user according to the geographic location information of the area where the ordinary user terminal is located, the load status of the transmission node, and the like.

Step 102: Send a request for a special permission to the first client according to the transmission path, and request the request to carry the preview information.

In the embodiment of the present invention, the special permission is in multiple forms, for example, broadcast stream data authority, and other clients may send an application request to the first client, and the application request is approved by the first client user. The client has special privileges only after the application request has been approved.

When the current client sends a special permission application request to the first client according to the pre-established transmission path, the client may carry the preview information in the application request for preview by the first client user. The preview information may be related to the information of the client user who sends the application request, and may be in various forms, such as video data, audio data, etc. When the preview information is audio and video data, the preview information may be a live stream data recorded on the spot. It can also be a pre-recorded piece of audio and video data.

In the video live broadcast scenario, when the normal user terminal pre-broadcasts the data, the application request for the broadcast stream data permission may be sent to the anchor end, and the application request carries the preview information of the ordinary user end user, such as the user's audio and video data.

Step 103: Receive an approval notification that the first client feeds back according to the preview information.

After receiving the application request carrying the preview information, the first client may display the preview information, and the first client user previews the preview information displayed, and approves the application request according to the preview result. Since the preview information provides a basis for the approval of the application request, carrying the preview information in the application request improves the experience of the approver and makes the approval result more accurate.

If the application request is approved, the first client will feedback the approval notification to the client that sent the application request, and the client has a special permission after the client receives the approval notification.

Take the video live broadcast scenario as an example. The live broadcast room includes the anchor, the guest, and the ordinary user. The anchor end has the broadcast stream data authority, and the anchor broadcasts the application request for the broadcast stream data authority sent by the ordinary user terminal for approval. When the ordinary user sends a request for the broadcast stream data to the anchor, the application request sends the video data of the ordinary user in the application request, and the anchor sends the video after receiving the application request, and the anchor can learn the video by watching the video. User-related information, and the application request is approved based on the video.

If the application request is approved, the anchor will feedback the approval notification to the ordinary user who sends the request. After the ordinary user receives the approval notification, the identity of the client changes, from the ordinary client to the guest, with broadcast stream data permission. .

According to the embodiment of the present invention, according to the transmission path when the first client transmits the first stream data, the application request for the special permission is sent to the first client, and since the application request carries the preview information, the user using the first client can preview the information. By reviewing and making judgments on the application request based on the viewing result, the user experience is improved, and the accuracy of the judgment result of the application request is improved. At the same time, the embodiment of the present invention uses the same transmission path to transport stream data and signaling, which eliminates the establishment of different transmission paths of convection data and signaling in the traditional method, and saves path establishment.

2 is a schematic flow chart of a method for transmitting a stream data according to a second embodiment of the present invention, which may specifically include the following steps:

Step 201: Receive first stream data transmitted from the first client according to the transmission path.

Step 202: Send a request for a special permission to the first client according to the transmission path, and request the request to carry the preview information.

A client may send a request for a special permission to the first client according to the pre-established transmission path. Specifically, the foregoing steps may be performed by the following method: First, the target transmission node passing through the transmission path may be recorded in advance. The uplink destination transmission node transmits the request request to the last target transmission node of the transmission path, that is, to the target transmission node directly connected to the client that sends the application request, and the last destination transmission node The application request is transmitted to its upstream destination transport node, as described above, until the request is transmitted to the first client.

In the network topology, for two adjacent transmission nodes in a transmission path, according to the transmission direction of the first client to other clients, the transmission node at the end of the transmission direction is defined as the transmission node at the beginning of the transmission direction. Downlink transmission node. For example, the transmission path of the first client to the second client is Node 1 - Node 2 - Node 3, the first client is directly connected to the node 1, the second client is directly connected to the node 3, and the node 2 is defined as the node 1. The downlink transmission node, node 1 is the uplink transmission node of node 2.

Secondly, when the first stream data is sent by the first client, the set of node identifiers of the target transmission nodes that are sequentially passed in the transmission process of the first stream data node is limited, and the application requesting client receives the first stream data after receiving the first stream data. The set of node identifiers is extracted, and the sent request request carries the set of node identifiers, and the application request may be transmitted to the first client through the at least one intermediate transport node in reverse order according to the set of node identifiers carried in the application request.

In the embodiment of the present invention, the application request of the special permission sent by a certain client to the first client carries the preview information, and the first client user can approve the application request according to the preview information.

When the preview information is audio and video data, the audio and video data may be collected in real time or may be pre-stored. Before the request for the special permission is sent to the first client according to the transmission path, the method of the embodiment of the present invention may further include: receiving a trigger operation of the user for the special permission, calling the audio and video collection interface to collect the audio and video data of the user, or The audio and video data of the pre-acquired user is extracted from the set position.

The method of transmitting the requested application is unicast, and the application request is unicast to the first client according to the transmission path between the client that sends the application request and the first client, and the application is made for the transmission node that passes the transmission path. The requesting unicast operation, the client sending the application request may cause the preview information to carry the first identifier of the unicast transmission type, so that the transmitting node sends the application request to the first client according to the first identifier. Specifically, the corresponding relationship between the identifier and the transmission mode may be recorded in the transit node, for example, the first identifier corresponds to the unicast transmission mode, and after the transmission node identifies that the preview information of the application request carries the first identifier, the transmission mode of the application request is determined as Unicast.

Step 203: Receive an approval notification that the first client feeds back according to the preview information.

After the first client user approves the application request for the special permission, the first client will feedback the approval notification to the client that sends the application request, and the client that sends the application request correspondingly receives the approval notification of the first client feedback, This has special permissions.

Step 204: Receive client information of a special client with special permission issued by the first client, and display the client information on the current client.

After the first client approves the application request of the special permission, the client information of the special client with special permission in the system changes, and the client information may include the number of the special client with special permission, the end identifier, the end state, and At least one of the maximum number of special clients.

To update the client information of the special client displayed by other clients in the system, the first client sends the updated client information of the special client to other clients, and the other clients will update the special client. The client information of the terminal is displayed. Specifically, the first client transmits the updated client information to the transit node directly connected thereto, and then transmits the updated client information to the access network topology according to multiple transmission paths in the network topology. Other clients and show. It should be noted that step 203 and step 204 may be performed simultaneously or sequentially, and the present invention is not limited thereto.

The first client can deliver the client information of the special client according to different timings. For example, the client information of the special client can be delivered immediately after the application request for the current special permission is approved, and the special client can be sent according to the preset time interval. Client information for the client.

If the client information of the special client stored locally by other clients is different from the client information of the newly delivered special client, the client information needs to be updated to display the updated client information.

Different version identifiers can be set for different client information. For example, the version identifier is a numerical value, and the value of the version identifier after each update is increased by 1. In this case, the locally stored and newly delivered special client clients can be determined by the following methods. Whether the end information is the same: the version identifier of the newly delivered client information is extracted, and compared with the version representation of the locally stored client information. If the comparison result is determined to be inconsistent, the locally stored and newly delivered client is determined. The information is different. The current client updates the locally stored client information and displays the newly delivered client information.

According to the embodiment of the present invention, according to the transmission path when the first client transmits the first stream data, the application request for the special permission is sent to the first client, and since the application request carries the preview information, the user using the first client can preview the information. By reviewing and making judgments on the application request based on the viewing result, the user experience is improved, and the accuracy of the judgment result of the application request is improved. At the same time, the embodiment of the present invention uses the same transmission path to transport stream data and signaling, which eliminates the establishment of different transmission paths of convection data and signaling in the traditional method, and saves path establishment.

Referring to FIG. 3, a schematic flowchart of a step of a method for transmitting stream data according to a third embodiment of the present invention is shown, which may specifically include the following steps:

Step 301: Receive first stream data that is transmitted from the first client according to the transmission path.

Step 302: Send a request for a special permission to the first client according to the transmission path, and request the request to carry the preview information.

In the embodiment of the present invention, the special permission is a broadcast stream data authority.

Step 303: Receive an approval notification that the first client feeds back according to the preview information.

Step 304: The second stream data is transmitted to the target transmission node, so that the second stream data is pushed by the target transmission node to the first client and the at least one second client, and the transmission path is transmitted through multiple targets. Node, each target transmission node has at least one associated transmission node.

In the embodiment of the present invention, the first client transmits the first stream data to the current client according to the pre-established transmission path. The transmission node through which the transmission path of the first client and the current client passes is referred to as a target transmission node, and the number of target transmission nodes is plural, and at least one target transmission node has an associated transmission node. The association transmission node may be a transmission node directly connected to the target transmission node, or may be a transmission node indirectly connected to the target transmission node through the directly connected transmission node.

The current client has the right to broadcast stream data after receiving the approval notification of the first client feedback. When the current client broadcasts the second stream data, the second stream data may be transmitted to each target transmission node through which the current client and the first client transmit the path, and if the target transit node has an associated transit node, the second stream is The data is pushed from the target transit node to the associated transit node, and finally the second stream data is pushed to the first client and the third client of the access network topology to complete the broadcast transmission of the second stream data.

Specifically, the second stream data may be pushed to the first target transmission node directly connected to the current client, and if the first target transmission node has the associated transmission node, the second stream data is pushed to the first target transmission. While the second target transmission node directly connected by the node, the second stream data is pushed from the first target transmission node to the associated transmission node, and the foregoing steps are performed cyclically, and finally the second stream data is pushed to the first client and the third Client.

When the first client and the current client push the streaming data at the same time, other user clients receive two streams of data, and other user clients synthesize the two streams of data, and display the synthesized stream data. .

After the current client has the broadcast stream data permission, the data may be unicast or broadcasted. In order for the transport node to determine the transmission mode required by the current client to transmit data, the second stream data transmitted by the current client may be broadcasted. The second identifier of the mode is used for each target transmission node to identify, and the second stream data is broadcast according to the second identifier, and finally the second stream data is pushed to the first client and the at least one second client.

In the video live broadcast scenario, the first client may be the anchor end in the live broadcast room, and the second client may be the other guest end or the normal user end in the live broadcast room. A normal user can send a request for a broadcast stream data permission to the anchor to send a connection request. After the application request is approved, the ordinary user becomes a guest with the broadcast stream data authority. When the guest broadcasts the live stream data, the live stream data can be pushed to the target transport node directly connected to the current guest, and the target transport node is located on the transmission path of the current guest and the anchor, from the directly connected target transport node, through other targets. The transit node and the associated transit node finally push the live stream data uploaded by the current guest to the anchor end, other guest end, and the common user end.

If the video stream data is simultaneously uploaded by the anchor end and the guest end, the client processes the received two video stream data, and finally displays the two parts of the video image simultaneously on the client interface, for example, in the form of picture-in-picture.

According to the foregoing analysis, in the embodiment of the present invention, the first stream data of the first client and the second stream data of the other client are forwarded by using the same transmission path, and the network topology does not change, thereby eliminating the second stream in the traditional method. The establishment of a new transmission path of data saves the path establishment time and ensures the real-time performance of the stream data transmission. Correspondingly, the embodiment of the present invention only needs to use one system to control the flow data forwarding of the first client and the flow data forwarding of the second client, thereby reducing system overhead.

According to the embodiment of the present invention, according to the transmission path when the first client transmits the first stream data, the application request for the special permission is sent to the first client, and since the application request carries the preview information, the user using the first client can preview the information. By reviewing and making judgments on the application request based on the viewing result, the user experience is improved, and the accuracy of the judgment result of the application request is improved. At the same time, the embodiment of the present invention uses the same transmission path to transport stream data and signaling, which eliminates the establishment of different transmission paths of convection data and signaling in the traditional method, and saves path establishment.

The embodiment of the present invention uses the target transmission node and its associated transmission node to push the stream data. When the associated transmission node has multiple levels, the layer-level stream data is pushed step by step, and finally the stream data is pushed to the access transmission node cluster. Clients that implement streaming data streaming.

Referring to FIG. 4, a flow chart of a method for transmitting a stream data according to Embodiment 4 of the present invention is shown. Specifically, the method may include the following steps:

Step 401: Transfer the first stream data from the first client to the third client according to the transmission path.

In the embodiment of the present invention, the system includes multiple clients, and the client and the client are connected through a transmission path in a network topology, and a certain client is connected to other clients based on multiple transmission paths.

A transmission path is established between the first client and the third client. When the first client sends the first stream data to the third client, the first stream data may be transmitted according to the pre-established transmission path.

Step 402: Receive a third client request for special permission, and forward the request to the first client according to the transmission path, and request the request to carry the preview information.

In the embodiment of the present invention, the special permission is in multiple forms, such as broadcast stream data authority, and the application request is approved by the first client user. If a client sends a request for a special permission to the first client, the client has special permissions only after the request is approved.

Providing the approval basis for the first client user, the embodiment of the present invention limits the third client to carry the preview information in the application request when the application request for the special permission is sent, and the preview information may indicate the related information of the client user who sends the application request. . The preview information may be in various forms, such as one or more of video data, audio data, text data, image data, and other forms of data. When the preview information is audio and video data, the preview information may be a live broadcast recorded on the spot. Streaming data can also be a pre-recorded piece of audio and video data.

Step 403: Forward the approval notification fed back by the first client according to the preview information to the third client.

After receiving the application request of the special permission, the first client may display the preview information carried in the application request on the client interface, and approve the application request according to the preview information, when the first client receives the user's request. Once the instructions are approved, an approval notification is generated and the generated approval notification is fed back to the third client. Since the preview information provides a basis for the approval of the application request, carrying the preview information in the application request improves the experience of the approver and makes the approval result more accurate.

In the embodiment of the present invention, preferably, each target transmission node through which the transmission path passes records its uplink target transmission node, and transmitting the first stream data from the first client to the third client according to the transmission path includes: searching for the last of the transmission path An uplink transmission node of the target transmission node, and transmits the application request to the searched uplink target transmission node; the uplink destination transmission node transmits the application request to its uplink destination transmission node until the application request is transmitted to the first client end.

The path direction of the transmission path of the first client and the third client is the first client to the third client, and the first target transit node through which the transmission path flows is connected to the first client, and the last one through which the transmission path flows The target transport node is connected to the third client.

When the third client sends an application request to the first client, the third client sends the application request to the target transmission node directly connected thereto, and can search for the uplink destination transmission node of the current target transmission node and push the application request to the In the manner of uplink transmission node, the application request is gradually transmitted, and finally the application request is pushed to the first client.

In the network topology, for two adjacent transmission nodes in a transmission path, according to the transmission direction of the first client to other clients, the transmission node that is located at the beginning of the transmission direction is the transmission node at the end of the transmission direction. Uplink transmission node. For example, the transmission path of the first client to the second client is Node 1 - Node 2 - Node 3, the first client is directly connected to the node 1, the second client is directly connected to the node 3, and the node 1 is defined as the node 2. The uplink transmission node, node 2 is the downlink transmission node of node 1, and uses the same method to limit other transmission nodes.

The uplink target transmission node of the current target transmission node can be found in various ways. For example, when the network topology structure is completed, the uplink transmission node of the transmission node in different transmission paths may be recorded in each transmission node, and specifically, the correspondence between the end identifier of the client connected to the transmission path and the uplink transmission node may be recorded, and secondly, The stream data may carry the client identifier of the second client, and after receiving the second stream data, the transit node may search for the corresponding uplink transport node according to the client identifier carried by the transport node.

For example, path 1 is the first client-node 1 - node 2 - node 3 - the third client, path 2 is the first client - node 1 - node 4 - node 3 - the fourth client, and the node 3 records the The corresponding relationship between the end identifier of the third client and the node 2 and the corresponding relationship between the end identifier of the fourth client and the node 4, and the second stream data transmitted by the third client carries the end identifier of the third client. The transmitting node may determine, according to the end identifier of the third client that is carried by the second stream data that is transmitted, and the corresponding relationship between the stored end identifier and the uplink transmitting node, that the corresponding uplink transmitting node is the node 2.

For another example, the first stream data transmitted by the first client may carry a set of target transmission nodes through which the transmission path passes, and multiple target transmission nodes in the set are arranged in order of flow, and the third client extracts and transmits after receiving the first stream data. The set of nodes, the second stream data sent by the node carries the set, and after receiving the second stream data, the transmitting node determines the uplink target transmission node of the current target transmission node according to the order of the multiple target transmission nodes in the set.

According to the embodiment of the present invention, according to the transmission path when the first client transmits the first stream data, the application request for the special permission is sent to the first client, and since the application request carries the preview information, the user using the first client can preview the information. By reviewing and making judgments on the application request based on the viewing result, the user experience is improved, and the accuracy of the judgment result of the application request is improved. At the same time, the embodiment of the present invention uses the same transmission path to transport stream data and signaling, which eliminates the establishment of different transmission paths of convection data and signaling in the traditional method, and saves path establishment.

Referring to FIG. 5, a schematic flowchart of a step of a method for transmitting stream data according to Embodiment 5 of the present invention is shown, which may specifically include the following steps:

Step 501: Transfer the first stream data from the first client to the third client according to the transmission path.

Step 502: Receive a third client request for special permission, and forward the application request to the first client according to the transmission path, and the application request carries the preview information.

In the embodiment of the present invention, the special permission is a broadcast stream data authority.

Step 503: Forward the approval notification fed back by the first client according to the preview information to the third client.

Step 504: Receive second stream data that is transmitted by the third client to the target transmission node, where the transmission path passes through multiple target transmission nodes, and each target transmission node has at least one associated transmission node.

In the network topology, there is a case where the transmission path and the transmission path meet, and the two transmission paths have a common transmission node. For example, the transmission path 1 and the transmission path 2 meet at the transmission node 1, and the transmission path is opposite to the transmission path 1. The other transport nodes other than the transport node 1 are referred to as the associated transport nodes of the transport node 1 on the transport path 1. The association transmission node may be a transmission node directly connected to a certain transmission node, or may be a plurality of transmission nodes directly and indirectly connected to a certain transmission node.

The step of receiving the second stream data that is transmitted by the third client to the target transit node may include: receiving the second stream data that is transmitted by the third client to the directly connected target transport node, according to the reverse order of the transmission path, The second stream data is sequentially pushed to other target transmission nodes.

Step 505: Push the second stream data from each target transmission node to the first client and the at least one second client via the associated transit node.

After receiving the second stream data, each target transmission node pushes the second stream data to its associated transmission node, and finally pushes the second stream data to the first client and the second client.

In the network topology, some transmission nodes have associated transmission nodes, and the associated transmission nodes may be directly connected transmission nodes or indirectly connected transmission nodes. The associated transmission node may be divided into multiple levels according to the node connection order, such as a primary associated transmission node, a secondary associated transmission node, a tertiary associated transmission node, etc., wherein the primary associated transmission node is directly connected to a certain transmission node. The transit node, the secondary associated transport node is a transport node that is directly connected to the primary associated transport node, and so on. The target transmission node through which the transmission path of the first client and the third client passes may include multiple connections, such as the target transmission node may directly connect with other target transmission nodes, the primary association transmission node, the first client, or the second client. .

When there is a multi-level setting of the associated transit node, the present step may be performed by: firstly, pushing the second stream data to the first-level associated transport node or the first client or the second client directly connected to the target transport node.

When the transmission paths of the first client and the third client are established, the downlink destination transmission node in the transmission path may be locally recorded on the target transmission node through which the transmission path passes. At this time, after the target transport node receives the second stream data transmitted by the third client, the second stream data is pushed to the first-level associated transport node or the first client or the third client that is directly connected to the target transport node. The method of the embodiment of the present invention may further include: searching for a downlink target transmission node of the target transmission node in the transmission path, and removing the sought downlink destination transmission from the primary association transmission node directly connected to the target transmission node. node. After the above removal step is completed, the target transmission node pushes the second stream data to the other level one associated transmission node except the found downlink destination transmission node.

All the primary association transmission nodes of the transmission node, that is, the uplink target transmission node and all the downlink destination transmission nodes may be recorded locally in each transmission node, and the node identifiers of all the primary association transmission nodes may be recorded. After completing the searching of the target transmission node in the downlink destination transmission node in the transmission path, the first-level associated transmission node directly connected to the target transmission node may be locally extracted from the target transmission node, and then all the first-level associated transmission nodes are extracted from the extracted one. The discovered downstream target transmission node is removed.

When the first client intersects or intersects with multiple transmission paths of different clients, the transmission node at the intersection or intersection locally records a plurality of downlink destination transmission nodes for multiple transmission paths. In order to find a downlink destination transmission node for a certain transmission path, the embodiment of the present invention may transmit the first stream data in a process of transmitting the first stream data by using a certain transmission path, and when the first stream data is transmitted to a target transmission node, the target transmission node is used. The downlink target transmission node in the transmission path is stored locally in the destination transmission node corresponding to the stream identifier of the first stream data.

After the first stream data is transmitted to the third client, the third client sends the second stream data, where the second stream data carries the stream identifier of the first stream data, and after the second stream data is transmitted to the target transport node, the target transport node The corresponding downlink destination transmission node may be extracted according to the flow identifier of the first stream data. Specifically, the target transmission node may extract the downlink target transmission node corresponding to the first flow identifier according to the flow identifier of the first flow data carried by the second flow data, and the corresponding relationship between the locally stored first flow identifier and the downlink target transmission node.

When the first stream data is transmitted to a certain target transmission node, the downlink transmission node of the target transmission node in the transmission path may be determined in multiple manners, for example, the first stream data carries nodes of all target transmission nodes through which the transmission path passes. The node identifiers of the plurality of target transmission nodes are arranged in an orderly manner according to the flow direction of the first client to the third client. After the first stream data is transmitted to a target transmission node, the node identifier of the current target transmission node may be acquired. Determining, according to the node identification sequence carried by the first stream data, that the next target transmission node to be transmitted is a downlink target transmission node.

The method further includes: searching for a downlink target transmission node of the target transmission node in the transmission path, where the method specifically includes: limiting the second stream data when the second stream data transmitted by the third client is transmitted to a target transmission node Carrying the node identifier of the target transport node, when the second stream data is transmitted to the next target transport node, after the next target transport node completes the extraction of the node identifier carried by the second stream data, the second stream data is carried The node identifier is changed, and is changed to the node identifier of the next target transmission node, and the second stream data is transmitted according to the above method. When the second stream data is transmitted to the current target transmission node, the node carried by the second stream data may be extracted. The manner of identification determines the downlink target transmission node of the current target transmission node in the transmission path.

Secondly, after the second stream data is pushed to the first-level associated transport node or the first client or the second client connected to the target transport node, the push step is performed iteratively, and the second stream data is received from the second stream data. The N-level associated transport node pushes to the directly connected N+1 level associated transport node or the first client or the second client until it is pushed to the first client and all second clients of the access transport node cluster.

Since the associated transport node of the target transport node may include multiple transport nodes that are directly connected and indirectly connected, multiple transport nodes may have multiple levels of association, so the second stream data transmitted by the third client is pushed to the level one association transmission. After the node, the loop performs an iterative step to push the second stream data to the second-level associated transport node, ..., the N-level associated transport node, and the N+1-level associative transport node until the first client is pushed to the access transport node cluster. And all the second clients, thereby completing the broadcast of the second stream data issued by the third client. Therefore, the embodiment of the present invention uses the target transmission node and the associated transmission node to broadcast the stream data to multiple clients.

In the embodiment of the present invention, before the second stream data is pushed from the target transmission node to the first client and the at least one second client, the method may further include: determining that the second stream data points to the broadcast transfer method.

Since the third client having the broadcast stream data authority can unicast the stream data to the first client to the first client, the stream data can also be broadcasted to the first client and the second client, so the target transit node receives the stream. After the second stream data is released by the third client, it is required to determine the transmission mode of the second stream data. If it is determined that the second stream data points to the broadcast transmission mode, broadcast transmission is performed; if it is determined that the second stream data does not point to The broadcast transmission mode, that is, determining that the second stream data is unicast, pushes the second stream data from each target transmission node to the first client.

The second stream data may be determined to be directed to the broadcast transmission mode by a plurality of methods, for example, by determining a method of including the identifier of the broadcast transmission mode in the data protocol header of the second stream data. The identification of the mode of communication can take many forms, such as numbers, letters, words, graphics, and the like. Different identifiers indicating different transmission modes may be set in advance on the user client, for example, setting the identifier “a” for the broadcast transmission mode, setting the identifier “b” for the unicast transmission mode, and limiting the flow when the client uploads the streaming data. Add the identifier corresponding to the data transmission mode in the data protocol header of the data; or set the end identifier for different clients in advance. For example, if the end identifier of the first client is set to “0”, the end identifiers of other clients except the first client are If it is "1", the end identifier "1" indicates the broadcast transmission mode, and when the client uploads the stream data, the end identifier of the destination client that receives the stream data is added to the data protocol header of the stream data.

Take the video live broadcast scenario as an example. You can preset the end identifier of the guest to be a positive integer, set the target identifier indicating the broadcast transmission mode to “0xFFFF”, and identify the guest end and its corresponding end identifier and the target identifier indicating the broadcast transmission mode. Stored on each transport node. If the transmission node identifies the target identifier "0xFFFF" indicating the broadcast transmission mode, it determines that the propagation mode of the second stream data is broadcast, and after identifying the guest identifier, determines that the client has the right to broadcast the stream data.

It is also possible to determine that the second stream data points to the broadcast transmission mode by determining a method in which the second stream data is transmitted to the plurality of destination clients.

When the second stream data is broadcasted in advance, the third client performs corresponding processing on the second stream data, so that the released second stream data carries the end identifier of the plurality of destination clients, the number of the plurality of destination clients, or the destination client. The number of ends is information such as multiple identifiers. Correspondingly, after the target transmission node recognizes the foregoing information, it is determined that the second stream data is a broadcast transmission mode.

In the embodiment of the present invention, preferably, after determining that the second stream data is directed to the broadcast transmission mode, the method may further include: determining that the third client has broadcast rights.

The second client can be determined to have broadcast rights in a plurality of manners, for example, a feature client set having broadcast rights can be found, and it is determined that the second client exists in the feature client set.

The feature client set is a set of clients with broadcast rights, and the feature client set is stored in each transport node. If it is determined that the second client is within the feature client set stored locally by the transit node, then the second client is determined to have broadcast rights.

According to the embodiment of the present invention, according to the transmission path when the first client transmits the first stream data, the application request for the special permission is sent to the first client, and since the application request carries the preview information, the user using the first client can preview the information. By reviewing and making judgments on the application request based on the viewing result, the user experience is improved, and the accuracy of the judgment result of the application request is improved. At the same time, the embodiment of the present invention uses the same transmission path to transport stream data and signaling, which eliminates the establishment of different transmission paths of convection data and signaling in the traditional method, and saves path establishment.
