Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which various embodiments of the present invention belong. The terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning that is consistent with their contextual meaning in the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein in various embodiments of the present invention.
Example 1
In this embodiment, an AA (active-active) mode-based recording method is provided, and is applied to a server, and by using the AA mode-based recording method, the server may manage a plurality of recording nodes, and when receiving a recording task, the server may control a plurality of recording servers to cooperatively execute the recording task, so as to improve the recording quality of an audio/video conference, not only prevent a code stream file of the recorded audio/video conference from being lost, but also ensure the integrity of the code stream file.
It should be noted that in this embodiment, in the AA (active-active) mode, at least two recording nodes execute a recording task at the same time, where the recording node executing the recording task is used as a target node, and behaviors of the target nodes when executing the recording task are completely consistent, that is, the recording task is executed synchronously, and a recording code stream file generated by executing the recording task is generated synchronously.
For example, referring to fig. 1, in the present embodiment, a recording method based on an AA (active-active) mode is provided, which includes the following steps S100 to S300:
step S100, when a recording instruction is received, selecting at least two target nodes from a plurality of recording nodes, wherein the target nodes are used for executing a recording task corresponding to the recording instruction.
Generally, the recording instruction may be that, after the conference starts, a conference administrator starts recording the conference through Web operation, or may set the recording to be automatically performed after the conference starts, or start recording through operation on a terminal of a participant.
In this embodiment, the server is configured to manage a plurality of recording nodes, and when receiving a recording instruction sent by a user, the server selects at least two recording nodes from the plurality of recording nodes as target nodes.
It can be understood that the server may not perform the recording task, but only manage the plurality of recording nodes, and certainly, in consideration of the maximum utilization of resources, the resource waste is avoided, the server may not only be used to manage the plurality of recording nodes, but also participate in the recording task as one recording node.
It should be noted that, if the server does not perform the recording task and is only used for managing a plurality of recording nodes, the server includes a recording scheduling service component (Record-Schedule) and a recording monitoring service component (Record-Monitor).
The recording scheduling service component (Record-Schedule) is responsible for selecting a target node for executing a recording task, and the recording monitoring service component (Record-Monitor) is used for monitoring the working condition of each recording node.
If the server can be used for managing a plurality of recording nodes and can also be used as one recording node to participate in a recording task, the server not only comprises a recording scheduling service component (Record-Schedule) and a recording monitoring service component (Record-Monitor), but also comprises a recording component (Record) and a transcoding component (Transfer-Code).
The recording component (Record) mainly performs recording service, that is, records an audio/video Code stream file in a conference, and the transcoding component (Transfer-Code) converts an original audio/video Code stream file into a required audio/video format for a player of a user to play.
In this embodiment, one implementation manner is that a recording scheduling service component of the server may randomly select at least two recording nodes from the plurality of recording nodes as target nodes and participate in a recording task at the same time. It can be understood that the greater the number of target nodes, the stronger the disaster tolerance of the audio/video conference recording process, but the excessive target nodes will cause resource waste.
In this embodiment, in order to avoid resource waste and ensure that the recording process of the audio/video conference has certain disaster tolerance, the server may randomly select two recording nodes from the plurality of recording nodes as target nodes, and the two target nodes participate in the recording task at the same time.
When any one target node is down or abnormal, the other target node does not affect the work of the other target node, the other target node executes the recording task normally, the recording task of the other target node is not interrupted, and the integrity of the recorded code stream file corresponding to the audio and video conference is further ensured.
For example, please refer to fig. 2, which illustrates a conference recording cluster including 3 recording nodes, in the conference recording cluster, each recording node has a conference in progress, that is, a conference 1 is executed on a first recording node, a conference 2 is executed on a second recording node, and after being scheduled by a recording management service component of a server, target nodes of the recording conference 1 include the first recording node and the second recording node, that is, the first recording node and the second recording node record the conference 1 at the same time; the target nodes for recording the conference 2 comprise a second recording node and a third recording node, namely the second recording node and the third recording node record the conference 2 at the same time.
Further, in view of the above random selection of the predetermined number of target nodes from the plurality of recording nodes, there may be some nodes of the plurality of recording nodes that are overloaded, i.e., that perform an excessive number of tasks, and some recording nodes that are underloaded, i.e., that perform a small number of tasks. Therefore, in this embodiment, in order to ensure load balance among the recording nodes and ensure reasonable utilization of resources of the recording nodes, another implementation manner for selecting a target node is provided, for example, please refer to fig. 3, where the implementation manner for selecting a target node includes the following steps:
s110: and acquiring the total number of tasks of each recording node.
A recording-monitoring service component (Record-Monitor) of the server may collect the recording task and/or transcoding task operation conditions of each node, and determine the total number of tasks of each recording node based on the recording task and/or transcoding task operation conditions.
For example, if 2 conferences are recorded in the first recording node and 2 recorded files are transcoded, the total number of tasks of the first recording node is 4; and if 10 conferences of the second recording node are recorded and 3 recorded files are transcoded, the total number of tasks of the second recording node is 13.
Further, a Record-monitoring service component (Record-Monitor) of the server sorts the recording nodes according to the total number of tasks of the recording nodes, for example, the recording nodes are sorted in the order from the smaller to the larger total number of tasks, or the recording nodes are sorted in the order from the larger to the smaller total number of tasks.
S120: and taking the first N recording nodes with the least total number of tasks as the target nodes, wherein N is a preset number.
And a recording scheduling service component (Record-Schedule) of the server takes the first N recording nodes with the minimum task total as the target nodes according to the task total of each recording node acquired by the recording monitoring service component (Record-Monitor).
For example, if the plurality of recording nodes are sequenced from small to large according to the sequence of the total number of the tasks, a predetermined number of recording nodes in the front of the sequence are used as target nodes; and if the plurality of recording nodes are sequenced according to the sequence of the total number of the tasks from large to small, taking the predetermined number of the recording nodes sequenced at the back as target nodes.
It can be understood that, in the embodiment corresponding to step S110 and step S120, load balancing between the recording nodes can be ensured, reasonable utilization of resources of the recording nodes is ensured, ordered recording tasks are ensured, and recording efficiency is improved.
And at least two target nodes synchronously execute the recording task corresponding to the recording instruction, thereby effectively ensuring that the recording task is not interrupted and ensuring the integrity of the recorded file.
And step S200, monitoring the working conditions of the plurality of recording nodes.
After the target nodes are determined, all the target nodes synchronously execute the recording tasks corresponding to the recording instructions. Meanwhile, a recording monitoring service component (Record-Monitor) of the server monitors the working conditions of a plurality of recording nodes in real time.
A recording monitoring service component (Record-Monitor) of the server acquires recording task information and/or transcoding task information of each recording node according to a preset sampling frequency; and determining whether each recording node is abnormal or not according to the recording task information and/or the transcoding task information of each recording node.
For example, the server may monitor the recording service, the transcoding service, the number of recording tasks, the number of transcoding tasks, and the like of each recording node in a mode of keeping the recording node alive once in 3 seconds, and if the server does not receive the related information of one recording node within a predetermined time period, it may be determined that the recording node is abnormal.
Step S300, when any one target node is abnormal, a new target node is reselected from the plurality of recording nodes according to the working conditions of the plurality of recording nodes, and the target node in a normal working state is utilized to synchronize the recording code stream file generated by executing the recording task to the new target node.
When any target node is abnormal, a Record-scheduling service component (Record-Schedule) of the server reselects a new target node from the plurality of recording nodes according to the working conditions of the plurality of recording nodes so as to replace the abnormal target node.
Illustratively, a Record-scheduling service component (Record-Schedule) acquires the total number of tasks of a normal recording node in a normal working state from a plurality of recording nodes according to the working conditions of the plurality of recording nodes; and taking a normal recording node corresponding to the minimum task total number as a new target node.
For example, referring to fig. 4, when the second recording node is abnormal, the target node of the conference 1 is updated from the first recording node and the second recording node to the first recording node and the third recording node, and meanwhile, since there is no code stream file recorded by the second recording node executing the recording task in the third recording node, the first recording node synchronizes the code stream file recorded by the executing the recording task to the third recording node, so as to ensure the integrity of the recorded code stream file corresponding to the conference 1 recorded in the third recording node.
Similarly, the target node of the recording conference 2 is updated to the first recording node and the third recording node from the second recording node and the third recording node, and meanwhile, since the second recording node does not execute the recording code stream file recorded by the recording task in the first recording node, the third recording node synchronizes the recording code stream file recorded by the recording task to the first recording node, so as to ensure the integrity of the recording code stream file corresponding to the recording conference 2 in the first recording node.
Further, when the third recording node is abnormal, if a fourth recording node exists, the target node for recording the conference 1 is updated to the first recording node and the fourth recording node from the first recording node and the third recording node, and meanwhile, because the fourth recording node does not have a recording code stream file recorded by the third recording node for executing the recording task, the first recording node synchronizes the recording code stream file recorded by the executing recording task to the fourth recording node, so that the completeness of the recording code stream file corresponding to the conference 1 recorded in the fourth recording node is ensured.
Similarly, the target node of the recording conference 2 is updated from the first recording node and the third recording node to the first recording node and the fourth recording node, and meanwhile, since the fourth recording node does not have a recording code stream file recorded by the third recording node executing the recording task, the first recording node synchronizes the recording code stream file recorded by the executing the recording task to the fourth recording node, so as to ensure the integrity of the recording code stream file corresponding to the recording conference 2 in the fourth recording node.
By analogy, the more the number of recording nodes is, the stronger the disaster tolerance of the recording system is.
In this embodiment, only when any target node is abnormal, the target node in a normal working state is used to synchronize the recording code stream file generated by executing the recording task to a new target node, and the IO read-write requirements on the disk of the recording node are low, which is convenient to implement.
It should be noted that, when the recording task of a certain conference is not executed by a predetermined number of target nodes, the server will receive an alarm to remind the user to respond in time.
Further, referring to fig. 5, in this embodiment, the recording method based on the AA mode further includes the following steps S400 to S600:
step S400, when the recording task is completed, determining a target node with the longest execution time for executing the recording task from the current multiple target nodes.
And step S500, controlling the target node with the longest execution time to transcode the recording code stream file generated by the recording task.
It can be understood that the current target node includes a recording code stream file corresponding to the complete audio and video conference, and the current target node can convert the original audio and video code stream file into a required audio and video format for a player of a user to play.
It should be noted that in this embodiment, the transcoding node may transcode the locally recorded code stream file, and trans-node transcoding is not required, so that a scenario that one node pulls the recorded code stream file from another node is avoided, and transcoding efficiency is further ensured.
It should be noted that, the more complete the recorded code stream file corresponding to the recording task executed by the target node executing the recording task, the fewer recorded code stream files obtained from other target nodes, the fewer the number of code stream files to be recorded during transcoding, and the higher the transcoding efficiency.
And step S600, controlling other target nodes to delete the local recorded code stream file.
When the conference is finished or the recording is stopped, other target nodes except the target node which has the longest time for executing the recording task delete the local recording code stream file of the conference, so as to save the disk storage space of other target nodes.
It should be noted that, in this embodiment, when one recording task is completed, the server may control the target node that has the longest time to execute the recording task to upload the complete recorded code stream file to the archive server, so as to ensure that the complete recorded code stream file can be stored for a long time.
Further, referring to fig. 6, in this embodiment, a signaling relationship between a recording scheduling service component (the recording schedule in fig. 6), a recording monitoring service component (the recording monitoring in fig. 6), a recording component of a first recording node (the first recording in fig. 6), a recording component of a second recording node (the second recording in fig. 6), and a recording component of a third recording node (the third recording in fig. 6) is given.
It can be understood that the embodiment has simple logic, is slightly modified on the original conference system, ensures that the conference system realizes high availability of the recording service with minimum modification, does not need to additionally purchase a third-party server, and has lower realization cost.
