The terminal 10 may also communicate with the stream forwarding server 20, for example, the terminal 10 may transmit a data request to the stream forwarding server to request a data stream, and receive and display the data stream transmitted by the stream forwarding server. The stream forwarding server 20 is mainly configured to request a data stream from the data source server 30 and send the data stream to the corresponding terminal 10, where the stream forwarding server 20 may also send a data stream received from the same data source server 30 to different terminals 10 at the same time. The data source server 30 is mainly used for providing data sources of data streams, the same data source server may provide only one data source, the stream forwarding server may request data streams from different data source servers according to the requirements of the terminal, and after receiving a data request sent by the stream forwarding server 20, the data source server 30 may establish a connection with the stream forwarding server and send a data stream to the stream forwarding server 20 through the connection. In the embodiment of the present invention, when the data source server 30 transmits a data stream to the stream forwarding server 20 through a connection with the stream forwarding server, if a connection abnormality is detected, the data source server controls the local server to stop transmitting the data stream to the stream forwarding server 20 through the connection. The connection between the stream forwarding server 20 and the data source server 30 is established by the data source server 30 according to the IP address of the stream forwarding server and the data stream port number of the stream forwarding server.

Fig. 2 is a schematic signaling interaction diagram of a data stream transmission method according to an embodiment of the present invention. The method is applicable to a data streaming system, such as the data streaming system shown in fig. 1. As shown in fig. 2, the method specifically includes:
s210, connection is established between the data source server and the stream forwarding server.
The connection is established between the data source server and the flow forwarding server according to the IP address of the flow forwarding server and the data flow port number of the flow forwarding server. The obtaining manner of the IP address of the stream forwarding server and the data stream port number of the stream forwarding server may include multiple manners.
In one example, when the data streaming system is operating normally, the terminal starts a data streaming service, and sends a data streaming request to the streaming forwarding server, where the data streaming request is used to request the streaming forwarding server to send the data streaming to the terminal. After receiving the data flow request, the flow forwarding server generates a random data flow port number according to the terminal, and sends the data flow request to the data source server, wherein the data flow request comprises an IP address of the flow forwarding server and the data flow port number of the flow forwarding server. And the data source server establishes connection with the flow forwarding server according to the IP address of the flow forwarding server and the data flow port number of the flow forwarding server.
In another example, when the data streaming system is operating normally, the terminal starts a data streaming service, and sends a data streaming request to the streaming forwarding server, where the data streaming request is used to request the streaming forwarding server to send the data streaming to the terminal. After receiving the data flow request, the flow forwarding server generates a random data flow port number according to the terminal, and sends the data flow request to the scheduling server, wherein the data flow request comprises an IP address of the flow forwarding server and the data flow port number of the flow forwarding server. After receiving a data stream request sent by a stream forwarding server, a scheduling server sends an IP address of the stream forwarding server and a data stream port number of the stream forwarding server to a data source server corresponding to the data stream. And the data source server establishes connection with the flow forwarding server according to the IP address of the flow forwarding server and the data flow port number of the flow forwarding server.
S220, when the data source server sends the data stream to the stream forwarding server through the connection between the data source server and the stream forwarding server, if the connection abnormity is detected, the data source server is controlled to stop sending the data stream to the stream forwarding server through the connection.
In another specific implementation, the data source server detects that the connection between the data source server and the flow forwarding server is abnormal in a plurality of ways.
In one example, the data source server fails to transmit the data stream to the stream forwarding server over the connection.
In another example, the data source server reaches a set value by the number of data stream transmission failures to the stream forwarding server through the connection. The set value can be determined according to actual needs.
In another example, the data source server may periodically send heartbeat detection messages to the stream forwarding server without receiving a response to the heartbeat detection messages.
In addition, after the connection abnormality is detected, a reconnection mechanism may be started, and when reconnection fails, the local server is controlled to stop sending the data stream to the stream forwarding server through the connection.
Specifically, the reconnecting mechanism may include the steps of:
the data source server establishes connection with the flow forwarding server again according to the IP address of the flow forwarding server and the data flow port number of the flow forwarding server;
and if the connection is failed to be reestablished and the failure times reach a set value, continuing to control the server to stop sending the data stream to the stream forwarding server through the connection. The set value can be determined according to actual needs.
In a specific implementation, the manner for controlling the local server to stop sending the data stream to the stream forwarding server through the connection may include multiple manners.
In one example, the data source server may directly stop sending data streams to the stream forwarding server over the connection.
In another example, the data source server may send a connection exception message to a scheduling server that schedules the present data source server. And after receiving the connection abnormal message sent by the data source server, the scheduling server sends a data stream stop sending instruction to the data source server. The data source server receives a data flow stop sending instruction returned by the scheduling server according to the connection abnormal message; and stopping transmitting the data stream to the stream transmitting server through the connection according to the indication.
In another example, the data source server may directly stop sending data streams to the stream forwarding server over the connection and send a connection exception message to the scheduling server.
After the data source server stops sending the data stream to the stream forwarding server through the connection, the context corresponding to the connection can be further deleted at the server.
Due to the abnormal connection between the flow forwarding server and the data source server, which may be due to the restart of the flow forwarding server due to the inflexibility, at this time, the flow forwarding server stops sending the data flow to the terminal. After the stream forwarding server is restarted successfully, the stream forwarding server starts a new round of service, and the data source server stops sending the data stream to the stream forwarding server, so that the data stream before the stream forwarding server is restarted is completely stopped from being sent, and the data stream after the restart cannot be interfered. If the terminal wants to continue to acquire the data stream service, the terminal needs to send a data stream request to the stream forwarding server again.
And S230, establishing connection between the data source server and the stream forwarding server, and sending the data stream to the stream forwarding server through the connection. The stream forwarding server is generally random when allocating the data stream port number, so that the data stream port number allocated to the data source server after the stream forwarding server is restarted can be the same as that allocated before the restart, and at this time, the IP address and the data stream port number pair according to which the connection established in S230 and S210 is based are the same; the number of the data stream port allocated to the data source server after the stream forwarding server is restarted may be different from that allocated before the restart, and at this time, the IP address and the number of the data stream port, which are used for the connection established in S230 and S210, are different.
In one example, after the stream forwarding server is restarted successfully, and a data stream acquisition request sent by a terminal is received, a random data stream port number is determined according to the terminal. And the stream forwarding server sends the IP address of the stream forwarding server and the data stream port number of the stream forwarding server to the data source server. The data source server receives a data stream request from the stream forwarding server, wherein the data stream request carries an IP address of the stream forwarding server and a data stream port number of the stream forwarding server; and establishing connection with the flow forwarding server according to the IP address of the flow forwarding server and the data flow port number of the flow forwarding server, and sending the data flow to the flow forwarding server through the connection.
In another example, after the stream forwarding server is restarted successfully, and a data stream acquisition request sent by a terminal is received, a random data stream port number is determined according to the terminal. The flow forwarding server sends a data flow obtaining request to the scheduling server, wherein the data flow obtaining request carries the IP address of the flow forwarding server and the data flow port number of the flow forwarding server. And the scheduling server sends the IP address of the flow forwarding server and the data flow port number of the flow forwarding server carried by the data flow acquisition request from the flow forwarding server to the data source server. The data source server receives an IP address of a stream forwarding server from a scheduling server and a data stream port number of the stream forwarding server; and establishing connection with the flow forwarding server according to the IP address of the flow forwarding server and the data flow port number of the flow forwarding server, and sending the data flow to the flow forwarding server through the connection.
According to the embodiment of the invention, when the data source server determines that the stream forwarding server fails, the data source server reports the error information and stops sending the data stream to the stream forwarding server, so that all data stream transmission is stopped when the stream forwarding server fails, and after the stream forwarding server is restarted, the data stream transmission is restarted, thereby reducing the possibility of streaming.
