Referring to fig. 4, fig. 4 is a flow chart illustrating an embodiment of a method for redirecting streaming media according to the present application. In the current embodiment, the execution subject of the method provided by the present application is an idle media server, and in the current embodiment, the method provided by the present application includes:
s410: and determining the media server to be replaced.
In the communication system, as described above, each media server detects itself or other media servers according to a set time period, so as to determine whether there is an abnormality in the media server, and when it is determined that there is an abnormality in the media server, notify the media server whose service processing resource meets a preset condition or directly determine that the abnormal media server is a media server to be replaced. In an embodiment, the idle media server may directly detect that there is an abnormality in the media server, and determine that the media server with the abnormality is a media server to be replaced. In another embodiment, the second other media server may also detect that there is an abnormality in the media server, and notify the idle media server that the service processing resource meets the preset condition. The idle media server is a media server with current service processing resources meeting setting conditions, wherein the setting conditions comprise that the available service processing resources are larger than or equal to a preset value, and the proportion of the available service processing resources to all the service processing resources is larger than or equal to a preset proportion. In other embodiments, when the number of media servers whose service processing resources meet the preset conditions is plural, the transmission distance of the idle media server is also considered at the same time when determining the idle media server, for example, one media server closest to the transmission distance of the abnormal media server is selected as the idle media server from among the media servers whose service processing resources meet the preset conditions.
In another embodiment, when a certain media server in the communication system needs to perform data service transfer due to its own needs or manual setting of an administrator, a notification may be sent by the media server to inform each media server in the system that the media server needs to perform data service transfer, so that a media server in the communication system with a service processing resource meeting a preset condition determines the media server as a media server to be replaced.
The media server to be replaced is a media server needing to transfer the service or having abnormality, and the idle media server is a media server finally executing the service of replacing the abnormal media server. As described above, the idle media server is a media server whose service processing resources meet the set conditions.
In another embodiment, the idle media server is a media server that detects an abnormal media server and that itself service resources satisfy a preset condition. In the present embodiment, the media server with the service processing resource meeting the preset condition may be one media server with the minimum operation pressure in all media servers in the communication system that normally operate, or the media server with the service processing resource meeting the preset condition may be one media server with the maximum available communication resource, or the media server with the service processing resource meeting the preset condition may be a completely idle standby media server without any service in operation, which is understood that the preset condition may be set or changed according to actual needs, and is not limited herein.
In step S410, the idle media server may directly determine that the media server is to be replaced, or may receive a service replacement notification sent by another media server in the communication system. The service take-over notification is sent to the media server with the service resources meeting the preset conditions by other media servers with abnormal detection or service transfer need, so that the media server with the service resources meeting the preset conditions determines the media server to be taken over, and further takes over the service of the media server to be taken over.
S420: take over the traffic of the media server to take over.
After the idle media server determines the media server to take over, further taking over the service of the media server to take over. Wherein, the services of the grafted media server to be grafted at least comprise: the service data stored on the media server to be replaced and other types of services established by the media server to be replaced are at least obtained and stored.
Further, the idle media server takes over the service of the media server to be taken over, and at the same time, obtains the identification information of the communication terminal related to the service of the media server to be taken over, so as to inform the communication terminal having the service to and from the media server to be taken over to change the direction of data interaction.
S430: the redirection request is sent to the terminal associated with the service via the RTCP protocol so that the terminal takes the idle media server as a new target media server for the service.
After taking over the service of the media server to take over, a redirection request is transmitted via RTCP protocol to the communication terminal associated with the taken over service so that the communication terminal associated with the taken over service takes the idle media server as a new target media server for its ongoing service.
Specifically, according to the acquired identification information of the communication terminal related to the service of the media server to be replaced, a redirection request is sent to the communication terminal related to the service through an RTCP protocol so as to inform the communication terminal to change the data interaction direction, and then the idle media server is used as a new target media server of the service.
The redirection request comprises a payload type, wherein the value of the payload type is a preset identification, and the redirection request is used for informing the terminal to send the data stream of the service to a new target media server. Specifically, the redirection request with the value of the payload type being the preset identity is used for informing the terminal to send the data stream of the service to the new target media server.
Further, in another embodiment, the redirection request further includes address information of the target media server for informing the terminal of the communication address of the target media server.
Referring to fig. 5, fig. 5 is a schematic diagram illustrating a part of a redirection request in an embodiment of a method for redirecting streaming media. In the partial structure diagram of the redirection request illustrated in fig. 5, V is an abbreviation of version number for indicating a version number of the current request, i.e., for identifying a version of the RTCP protocol, P is a generic name of Padding, FMT is an abbreviation of feedback message type, which is a feedback information type indicating the current redirection request, and PT is an abbreviation of payload type for indicating a current payload type. Wherein different payload types correspond to different signaling, as in the current embodiment, when the payload type is PT (239) as illustrated in fig. 5, then the current redirection request is used to notify the communication terminal that is sending traffic with the media server to be replaced to send the data stream of the traffic to the new target media server.
Further, the address information includes an IP address and a real-time transport protocol port. With continued reference to fig. 5, as illustrated in fig. 5, new Media Server RTP IP is configured to notify an IP address of a target media server to which a communication terminal that is transmitting a service with the media server to be replaced needs to connect, new Media Server RTP Port is configured to notify a real-time transport protocol port of the communication terminal, so that the communication terminal can transmit a data stream to the corresponding target media server with the IP address, so that service reconstruction is completed between the communication terminal and the target media server, and further, the communication terminal performs data interaction with the target media server instead due to the data interaction with the media server to be replaced.
Still further, the redirect request also includes a type of the target media server. With continued reference to fig. 5, the Team Type in fig. 5 is used to indicate the Type of the target media server, so that the terminal can change other relevant parameters according to actual needs.
According to the technical scheme provided by the application figure 4, after the idle media server determines the media server to be replaced in the communication system, then the service of the media server to be replaced is replaced, and a redirection request is sent to the communication terminal related to the service of the media server to be replaced through an RTCP protocol, so that the communication terminal takes the idle media server as a new target media server of the service, the recovery of the service is completed rapidly when the media server is abnormal or the service is required to be transferred, and stable data interaction is ensured when the media server is abnormal or the service is transferred, thereby improving the experience of users.
Referring to fig. 6, fig. 6 is a flow chart illustrating another embodiment of a method for redirecting streaming media according to the present application. In the current embodiment, step S110 of the idle media server determining that the media server is to be replaced includes step S601 and step S602. The method comprises the following steps:
s601: the idle media server detects whether the first other media server connected with the idle media server needs to transfer service or is abnormal.
In the present embodiment, the idle media server detects whether the first other media server connected to itself needs to transfer the service or is abnormal. Wherein the first other media server is a media server connected to the media server performing the detection. The media server in the communication system detects whether the first other media server connected with the media server needs to transfer the service according to the set period. It should be noted that, when a certain media server detects that an abnormality occurs in a first other media server connected to the certain media server, it detects that the first other media server connected to the certain media server needs to transfer services, and then step S602 is executed, otherwise, step S601 is executed continuously.
Further, in the technical scheme provided by the application, the media server also detects whether the media server is abnormal according to the set period, and when detecting that the media server is abnormal, and when the media server still can externally communicate, the media server externally sends a service take over notification requesting to take over the media server, so that the idle media server determines the media server as the media server to take over.
Similarly, when it is detected that the administrator issues a setting instruction to the first other media server connected to the administrator to terminate the first other media server to provide the communication service for the external communication terminal, it is determined that the media server or the first other media server needs to transfer the service, and then step S602 is executed, otherwise, step S601 is continuously executed.
Further, in the technical scheme provided by the application, the media server also detects whether an administrator sends a setting instruction to the media server according to a set period, when the media server detects that the administrator sends the setting instruction to the media server to terminate the media server to provide communication service for an external communication terminal, the media server is judged to need to transfer service, and at the moment, the media server can send out a service take-over notification requesting to take over the media server to the outside, so that the idle media server determines the idle media server to be the media server to take over.
S602: and taking the first other media server as a media server to be replaced, and taking the first other media server as an idle media server when the service processing resource of the first other media server meets the preset condition.
If the currently detected media server detects that a first other media server needing to transfer the service or having an abnormality exists, the current media server takes the first other media server as a media server to be replaced, and takes the current media server as an idle media server to replace the service of the media server to be replaced when determining that the service processing resource of the current media server meets the preset condition, and then sends a redirection request to a terminal related to the service through an RTCP protocol, so that the terminal takes the idle media server as a new target media server of the service.
In another embodiment, when the current media server determines that the own service resource does not meet the preset condition, and detects that there is a first other media server that needs to transfer the service or is abnormal, the current media server sends a service take-over notification to the outside, so that the other media servers in the communication system with own service resources meeting the preset condition serve as idle media servers, and further take over the service of the media server to be taken over.
Therefore, in another embodiment, before the idle media server determines that the media server is to be replaced in step S110, the method further includes: and receiving a service succession notice.
The service succession notification is generated when the second other media server detects that the service to be transferred exists or an abnormal media server to be succession exists, and the second other media server sends the service succession notification to the idle media server of which other service processing resources in the communication system meet preset conditions. It should be noted that, in the present embodiment, the second media server that detects the presence of the to-be-replaced media server that needs to transfer the service or that is abnormal is not the same media server as the idle media server that eventually takes over the to-be-replaced media server.
The media server with the service processing resource meeting the preset condition may be one media server with the minimum operation pressure in all media servers in the communication system which normally operate, or the media server with the service processing resource meeting the preset condition may be one media server with the maximum available communication resources, or the media server with the service processing resource meeting the preset condition may be a completely idle standby media server without any service in operation, which is understood that the preset condition of the service processing resource may be set or changed according to the actual requirement, and is not limited in this embodiment.
S603: take over the traffic of the media server to take over.
S604: the redirection request is sent to the terminal associated with the service via the RTCP protocol so that the terminal takes the idle media server as a new target media server for the service.
In the present embodiment, step S603 and step S604 are the same as step S420 and step S430 illustrated in fig. 4, and reference is specifically made to the description of the relevant portions above, and detailed description thereof will not be repeated here.
Referring to fig. 7, fig. 7 is a flow chart illustrating an embodiment of a method for redirecting streaming media. In the current embodiment, an execution subject of the method provided in the present application is a communication terminal, and the method includes:
s710: a redirect request is received.
Wherein the redirection request is sent to the terminal via RTCP protocol.
Further, in an embodiment, step S710 includes: the terminal receives a redirection request sent by the idle media server through the RTCP protocol.
When a terminal related to the media server service to be replaced receives a redirection request sent by an idle media server through an RTCP protocol, judging whether redirection of the streaming media service is needed or not further based on the effective load type in the redirection request, namely the PT value.
Wherein the redirect request includes a payload type and the value of the payload type includes a preset identification to indicate that the redirect request is to notify sending of the data stream of the corresponding service to the new target media server. The data structure of the redirection request is described with reference to fig. 5 and its corresponding embodiment, and is not described in detail herein.
When the value of the effective load type is a preset identification, the current redirection request is indicated to be used for informing the terminal to send the data stream of the corresponding service to a new target media server. In one embodiment, the preset identifier includes 239. When the PT value in the received redirect request is 239, the communication terminal regards the idle media server as a new target media server for the corresponding service in response to the redirect request. It can be appreciated that in other embodiments, other types of identifiers may be set to inform the terminal to redirect the streaming media according to the actual requirements and the requirements of the communication protocol.
Further, in another embodiment, the redirection request further includes address information of the target media server, and the terminal may obtain the address information of the target media server by parsing the redirection request.
S720: the idle media server is treated as a new target media server for the corresponding service in response to the redirect request.
The idle media server is a media server with service processing resources meeting the set conditions, and the redirection request comprises address information of a target media server. After receiving the redirection request sent by the idle media server through the RTCP protocol, the terminal establishes connection with the target media server based on the address information of the target media server included in the redirection request, so as to change the connection with the target media server to continue the data service interaction.
Further, responding to the redirection request, taking the idle media server as a new target media server of the corresponding service, comprising:
