The audio management server is an important guarantee for users to perform smooth conferences for processing data. The existing audio management server is mostly guaranteed to adopt a main backup mode to perform switching no matter what the audio management server is switched, namely the switching of the main backup, but the audio management server is very important for the integrity of data replication in the main backup switching process. How to realize the high reliability and the availability of the audio management server, and avoid the unavailability of the audio management server, which leads to the unavailability of users, thereby influencing the interruption of the conference, influencing the communication efficiency, further leading to the reduction of the user performance, and becoming a problem which needs to be solved urgently.
The invention aims to provide a method for ensuring high availability of an audio management server during switching and ensuring smooth communication of users.
Disclosure of Invention
In order to solve at least one of the above technical problems, the present invention provides a management method for switching audio management servers, including, in step S01, a management unit sets three message queues, one is a to-be-sent distributed message queue, one is a buffer-sent distributed message queue, and the other is a to-be-confirmed sent distributed message queue;
step S02, the management unit determines the fault type between the user terminal and the audio management server by sending a probe message,
step S03 executes management control of the audio management server based on the judgment of the type of failure;
the fault type between the user terminal and the audio management server comprises the following steps: network line faults and audio management server faults;
the management unit detects the fault type between the user terminal and the audio management server by sending the detection message, and comprises the following steps: when the message value of the distributed message queue to be confirmed is larger than a set threshold value, sending a detection message to an audio management server, and feeding back the detection message when the detection message is received by the audio management server so as to determine whether the network line fault or the audio management server fault occurs;
when the audio management server is determined to be unavailable, forwarding the message data in the distributed message queue to be sent to a backup audio management server;
when the network is judged to have a fault and the fault is a flash fault, distinguishing the sent message data, distinguishing whether the message data is ordered message data or unordered message data, and when the message data is ordered message data, encapsulating the ordered message data with the same theme in the message data packet of the same type and putting the message data in the same distributed message queue to be sent; and when the message data is judged to be unordered message data, putting the unordered message data into a distributed message queue to be sent according to the receiving sequence to execute sending.
Further, when the detection message judges that the audio management server is unavailable, an overtime notification message is sent to the unavailable audio management server, and when the unavailable audio management server knows that the conference message is sent to the standby audio management server by the to-be-sent message distributed queue for processing, the unavailable audio management server sends the conference data in the unavailable audio management server to a cache sending distributed message queue.
Further, the ordered message data is an operation command with a time logic sequence, when the network is judged to be in a flash failure, the management unit reduces the transmission rate of the data message, simultaneously sends an operation command merging instruction to the audio management server, and encapsulates a plurality of operation records corresponding to a plurality of updating operations in a message data packet according to an execution sequence.
Further, when the message value of the to-be-confirmed sending distributed message queue is continuously lower than the set threshold value, the message data to be sent is segmented again, a plurality of message queues are dynamically added, and the message data of the same subject sequence is sent in parallel.
Further, the sending is performed on the ordered message data and the priority of the same subject.
Further, when the network fault is judged to be the flash fault, the network transmission rate is reduced, and when the time delay is increased, the classified packing and compression transmission are carried out on the message data according to the time delay, the message compression processing time and the audio management server processing performance, wherein the size of the classified packing depends on the message processing time, the network time delay and the audio management server processing performance.
Further, the backup audio management server receives the conference message, and when the conference message cannot be searched in the local memory, the backup audio management server loads conference data related to the conference message in the conference data cache in the distributed queue; after the backup audio management server finishes the conference data loading, the backup audio management server creates a data conference and a data user, and then creates a telephone conference and a telephone user according to whether the telephone conference exists or not; the conference call and the telephone subscriber are then created and the management unit subscribes to the conference call messages.
Further, when the network flash breaks down, the distributed message queue to be sent does not discard or forward the message to another audio management server within a set time period when the network is overtime.
Further, when the network is judged to be in a flash fault, the audio management server stops sending message data and initiates system configuration parameter synchronization when the network is recovered to be normal, and when the asynchronous state is found, the audio management server requests the current state of the client to the client, and the server synchronizes the state in the memory of the server according to the state.
Further, when the network flash failure is judged, the management unit sends an event notification to the audio management server, and the audio management server receives the event notification and then goes to the management unit to subscribe all the teleconference messages in the memory of the management unit again until the subscription is successful.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
Only one audio management server works in a conference, audio operation requests in the conference are sent to the audio management server for processing, and when the audio management server is abnormal, switching logic is executed to ensure high availability of the audio management server.
The audio management server ensures high availability of the audio management server based on the distributed message queue and the distributed cache, and the scheme of the invention does not need a separate switching management server and has clear logic.
Fig. 1 is a schematic diagram of an implementation of a structure of the present invention, in which the functions of a management unit may integrate the functions in a teleconference server and the functions of setting of a buffer queue, and an audio management server may also integrate the functions of a proxy server. The arrows in fig. 1 are merely schematic, and those skilled in the art know that interaction of information between various devices can be performed.
As shown in fig. 2, in step S01, the management unit sets three message queues, one is a to-be-sent distributed message queue, one is a buffer-sent distributed message queue, and the other is a to-be-confirmed-sent distributed message queue;
the specific steps in recovering and managing and controlling the data of the new audio management server are as follows: when the audio management server is abnormally crashed or the network is disconnected, another audio management server is selected to take over the conference in the abnormal audio management server; another new audio management server will be selected to need to restore the data in the conference and synchronize the data state between the audio management server and the teleconference management server.
Optionally, the management unit sets three distributed message queues, one is a to-be-sent distributed message queue, one is a buffer sending distribution, and the other is a to-be-confirmed sending distributed message queue. Through the setting of the distributed message sequence to be confirmed and sent, the message queue cannot be blocked in the distributed message queue to be sent, and the data synchronization of other user terminals communicating with the audio management server is improved.
When the value of the to-be-confirmed sent distributed message queue is larger than a set threshold value, sending a detection message to an audio management server, feeding back the detection message by the audio management server when receiving the detection message, determining whether the network line fault or the opposite-end audio management server fault exists through the detection message, and forwarding the message data in the current to-be-sent distributed message queue to an audio management server B when determining that the audio management server A is unavailable. The audio management server B receives the conference message, and if the conference of the message cannot be searched in the local memory, the conference data is loaded in the conference data cache in the distributed queue; after the audio management server B finishes the conference data loading, the audio management server B establishes a data conference and a data user, and then establishes a telephone conference and a telephone user according to whether the telephone conference exists or not; then create the telephone conference and the telephone user, and then go to the telephone conference management server or the message of subscribing the telephone conference in the management unit.
In order to simplify the logic of the audio server, the user continues to activate the conference call in the call management server or management unit after subscribing to the conference call without determining whether the conference call is already activated (the conference call management server ensures that the conference call activation interface cannot report an error for the already activated conference call).
Optionally, when the detection message determines that the audio management server a is unavailable, a timeout notification message is sent to the audio management server a, and when the unavailable audio management server a knows that the message of the conference corresponding to the self memory has been sent to another audio management server by the distributed message queue for processing, the conference data in the audio management server a is sent to the distributed session queue cache data, and at this time, the conference data in the self memory is dirty data and must be cleaned up, and meanwhile, the conference call management server needs to be visited to cancel the message of the subscribed conference call.
Optionally, when the network is judged to have a flash failure, the sent message data is distinguished, whether the message data is ordered message data or unordered message data is distinguished, and when the data is ordered message data and message data with the same theme are ordered messages, the message data is packaged in the same message data packet and is put into the same message queue. And when the message data is judged to be unordered message data, putting the unordered message data into a message queue according to the receiving sequence to execute sending.
Optionally, the ordered message data is specifically an operation command with a time logic sequence, and optionally when it is determined that the network is in an interruption fault, the transmission rate and quality of the data packet are reduced, and a merge message instruction is sent to the audio management server, where the merge message instruction may refer to encapsulating, according to an execution sequence, a plurality of operation records corresponding to a plurality of similar update operations in the command with the operation sequence into one piece of message data, storing the message data in a merge message queue, reducing the network transmission rate, and sending the command to the audio update server. One updating operation can also correspond to a plurality of operation records, and a plurality of operation command records corresponding to the same or a plurality of updating operations are encapsulated into a message data according to the execution sequence, thereby preventing the occurrence of disorder condition and ensuring the correctness of the synchronization process.
Optionally, when the sending information of the distributed message queue to be confirmed is continuously lower than the set threshold, the message data to be sent is segmented again, a plurality of message queues are dynamically added, and the message data packets of the same subject sequence are sent in parallel. Optionally, the data of the same ordered subject is fixed in a message queue for sending or sent preferentially. The message is distinguished, and the clustering analysis is carried out on the message operation instruction and the message content theme, so that the rapidness of message transmission is guaranteed, and the continuity of system setting commands is also guaranteed.
The judgment of whether the receiving network is flash-off is based on the network delay of the detection message, and can also be carried out through other indexes, such as network packet loss rate and the like.
When the network transmission is decreased and the time delay is increased due to the flash failure, classified packet compression transmission is carried out on the message data packets according to the time delay, the message compression processing time and the management audio server processing performance, and the size of the classified packets depends on the message processing time, the network time delay and the management audio server processing performance.
It can be known that during the time period of network timeout, the distributed message queue will not discard or forward the messages to other audio management server, and when the network recovers, the distributed message queue will continue to send the messages, thus ensuring the synchronization of the state of the data conference.
The audio management server stops sending message data when the network returns to normal, the sending system configuration parameters are synchronous, when the asynchronous state is found, for example, the user needs to mute by itself, and the audio management server finds that the user is muted, at this time, the audio management server requests the current state of the user from the client of the user, and the server synchronizes the state in the memory of the server according to the state.
Optionally, conference data of the teleconference is synchronized, when the network of the teleconference and the conference management server is flashed, the audio management server has an event notification, and after receiving the event notification, the audio management server goes to the teleconference management server again to subscribe all teleconference messages in the memory of the audio management server until the subscription is successful. When the conference call management server receives the subscription request of the audio management server, all the data in the conference call are sent to the audio management server once, and the audio management server can ensure that the data in the memory of the audio management server is up to date according to the data.
The data conference and conference data are synchronous, so that the client can carry out the teleconference when the audio management server fails or the network fails, and the complete conference of the audio management server is effectively ensured.
Optionally, when the network is completely interrupted, executing a polling detection mode on the detection message, stopping sending other message data, sending an alarm message to wait for network recovery, and optionally executing transmission of the alarm message through a third-party relay network.
