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 application.

Fig. 1 is a schematic structural diagram of a video networking network according to an embodiment of the present application. In the present application, each geographic area (obtained by pre-dividing) corresponds to one video network, the video network corresponds to one video server cluster, and a specific structure of the video server cluster may be as shown in fig. 1. In fig. 1, a black bold solid line box represents a node device. Each node device is a server, and the inside of each node device comprises a database, an operation and maintenance system, a storage system, a meeting management system, a network management system and an autonomous system.

Wherein the types of the node devices include: a master node, a standby node and a slave node. In a video network server cluster, one master node, one standby node and a plurality of slave nodes are arranged. In fig. 1, the master node is a server a1, and includes a database a1, an operation and maintenance system a1, a storage system a1, a conference management system a1, a network management system a1, and an autonomous system a 1; the standby node is a server A2 and comprises a database A2, an operation and maintenance system A2, a storage system A2, a meeting management system A2, a network management system A2 and an autonomous system A2; and the slave node is a server B and comprises a database B, an operation and maintenance system B, a storage system B, a meeting management system B, a network management system B and an autonomous system B.

In fig. 1, a plurality of servers, switches, slave devices, and terminals form the entire network of the video network. The master node and the standby node are both managed by the same integrated management server a (the dotted line square in fig. 1 represents the integrated management server), and the integrated management server a manages the server a1 and the server a2 by adopting a dual-server hot standby mechanism (comprising a master server and a standby server, wherein the two servers are autonomously connected with the same video network server). The number of slave nodes of the video network may be one or more, and the case where there are 3 slave nodes is shown in fig. 1, which are, in turn, server B (managed by the integrated management server B), server C (managed by the integrated management server C), and server D (managed by the integrated management server D).

The conference management refers to a conference management scheduling system, and is responsible for internal logic processing of conference operations, such as speaker switching, conference opening/closing, dynamic addition and deletion of participants, and the like. The program is divided into a meeting management front-end WEB management program and a background scheduling program, the scheduling program is divided into a CMS (content management system) and a DMS (service management system), the CMS is responsible for interaction with a WEB interface, and the DMS is responsible for bottom meeting opening, meeting control logic and the like.

The network management refers to an OMC network management system of the video network, and the system is responsible for the functions of registration, logout, real-time state monitoring, user authority management, terminal level, validity verification and the like of various video network video terminals, switches and routers.

The autonomous system is used for controlling the video network core server to carry out conference service operations such as meeting pulling and meeting controlling through the video network protocol.

The databases on multiple servers (multiple node devices) are synchronized in real time to ensure the data consistency of each node, so that the conference service can be conveniently recovered by managing the data stored in the databases.

The storage system is used for storing data in the running process of the nodes.

And the operation and maintenance system is used for maintaining the normal operation of the whole node.

The application provides a conference recovery method which is applied to any node device in figure 1. Fig. 2 is a flowchart illustrating a conference resuming method according to an embodiment of the present application. Referring to fig. 1, the conference resuming method of the present application may include the steps of:

step S21: in the video conference of the video network, when needing to activate the node equipment as the active node in the video network, confirm the activation type, the activation type is confirmed according to the node type of the original active node of the video conference of the video network and node type of the node equipment, the active node is the only node equipment offering video network service in the video network.

In this embodiment, each node device may be in communication connection with other node devices, and each node device stores therein node profiles of the other node devices. The node configuration file records the types and roles of the node devices, where the types of the node devices may include a master node, a slave node, and the roles of the node devices may include: an active node and an inactive node. Only one node device can be in an active state at the same time in the video networking network, that is, only one node device can provide video networking services (for example, video networking video conference services) to the outside at the same time in the video networking network, the node device is an active node, and the other node devices are inactive nodes.

In step S21, the video conference is ongoing on the active node, and if the active node suddenly fails, a new active node needs to be reactivated, and the video conference interrupted on the old active node is resumed on the new active node. In the process, the old active node is the original active node of the video conference of the video network. Wherein the activation type may be determined according to the type of the old active node and the type of the new active node.

In this embodiment, the node device may detect whether activation as an active node is required, or other devices may detect whether activation as an active node is required, and if so, notify the node device to activate itself as an active node. In practical implementation, it may be detected in any manner whether the node device needs to be activated as an active node in the video networking network, which is not limited in this embodiment.

For the convenience of the subsequent statements of various embodiments, the present application describes a conference recovery method by taking the example of detecting whether activation as an active node is required by the node device itself. In implementation, the network manager inside the node device may detect whether the node device needs to be activated as an active node.

In this embodiment, the activation sequence of each node device in the video network may be preset, and when a certain node device fails, other node devices may be activated according to the preset priority sequence. For example, with respect to fig. 1, the activation sequence may be set to: master node > backup node > slave node B > slave node C > slave node D, such that when the master node fails, the backup node may be activated, when the backup node fails, slave node a may be activated, when the slave node a fails, slave node B may be activated, and so on.

In the activation sequence described above, if the active node in the network shown in fig. 1 is server a1, at some point in time if server a1 fails, then server a2 needs to be activated as the active node. If the active node in the network shown in fig. 1 is server B, server C needs to be activated as the active node if server B fails at a certain time.

In specific implementation, for a certain node device, when it is detected that a certain other node device connected to the node device fails, it may be determined whether the node device is an active node by looking up a node configuration file of the failed node device, and if the failed node is an active node, it is determined whether the node device is a new active node (a node device that takes over the failed active node) according to a preset activation sequence, and if so, the activation type continues to be determined.

The activation type may include three types, namely, master-slave switching, slave-slave switching, and slave-master switching, where the master-slave switching indicates switching from a master node to a slave node or switching from the slave node to the master node. From handover means handover from a standby node to a slave node or handover between different slave nodes. A master switch means a switch from a slave node to a master node or a switch from a slave node to a standby node. The activation type will be described later in detail.

Step S22: and restoring the video conference of the video network on the node equipment according to the conference restoring strategy corresponding to the activation type.

In this embodiment, different conference recovery policies may be set for different activation types in advance, and the video conference interrupted when the old active node fails is recovered on the new active node after activation according to the conference recovery policies.

In this embodiment, since the database on each node device is synchronized in real time, the conference manager of the node device as the new active node can directly read the conference data of the interrupted video conference from the database and resume the video conference.

For example, taking fig. 1 as an example, if an old active node is a master node and a video conference (conference ID: XXXX) created by the old active node is interrupted when the master node fails, when a next-stage node (i.e., a standby node) of the old active node learns that the old active node needs to be activated as an active node, determining that the activation type is active-standby switching, and obtaining a corresponding conference recovery policy, then reading conference data of the video conference (conference ID: XXXX) to be recovered from a database of the old active node according to the conference recovery policy, and recovering the video conference (the recovered conference ID is still XXXX).

In this embodiment, the steps S21-S22 can be executed by a conference pipe in the node device.

According to the conference recovery method, in the video networking video conference, when the node equipment needs to be activated as the active node in the video networking network, the activation type is firstly determined, the activation type is determined according to the node type of the original active node of the video networking video conference and the node type of the node equipment, and the active node is the only node equipment which provides video networking service in the video networking network. And then, according to the conference recovery strategy corresponding to the activation type, recovering the video conference of the video network on the node equipment. The method sets corresponding conference recovery strategies aiming at the switching operation among different types of active nodes in the video network, so that the node equipment can recover the interrupted video conference of the video network according to the characteristics of the different types of switching operation.

With reference to the foregoing embodiment, in an implementation manner, the present application further provides a method for determining an activation type, which may specifically include:

when the original active node is a main node and the node equipment is a standby node, or the original active node is a standby node and the node equipment is a main node, determining that the activation type is main-standby switching;

when the original active node is a standby node and the node equipment is a slave node, or the original active node and the node equipment are different slave nodes, determining that the activation type is slave switching;

and when the original active node is a slave node and the node equipment is a master node, or the original active node is a slave node and the node equipment is a standby node, determining that the activation type is slave-to-master switching.

Each step in this embodiment is performed by the rendezvous point of the target node.

In this embodiment, each node device stores a corresponding relationship between an activation type and a node type of the node device, so that the node device can quickly determine the activation type according to the corresponding relationship after obtaining the node type of the old active node. The correspondence may be stored in the form of a table, for example, as shown in table 1 below:

type of activation	Type of node device
		Master-slave switching	Master node>Standby node and standby node>Master node
From slave switch	Backup node>Slave node, slave node>Slave node
		Slave-master handover	Slave node>Master node and slave node>Backup node

TABLE 1

In table 1, the nodes before the > sign indicate the node types of the original active nodes (old active nodes), and the nodes after the > sign indicate the node types of the node devices as the new active nodes. Specifically, when the master node is switched to the standby node, or the standby node is switched to the master node, the active type of the master-standby switching is corresponded. When switching from a standby node to a slave node, or between two different slave nodes, corresponds to the type of activation of the slave to switch from. When the slave node is switched to the master node or the slave node is switched to the standby node, the activation type of the slave-master switch is corresponded.

The corresponding relation between the activation type and the node type of the node device is set in this embodiment, so that the node device can quickly determine the activation type according to the corresponding relation after obtaining the node type of the original active node and the node type of the node device, and the conference recovery efficiency is improved.

With reference to the foregoing embodiment, in an implementation manner, the present application provides a conference resuming policy, and on this basis, resuming a video conference on a node device according to a conference resuming policy corresponding to an activation type may include the following steps:

determining a delay waiting time corresponding to the activation type;

and when the delay waiting time is reached, starting the video network video conference aiming at the participating terminals which are added into the video network video conference.

Each step in this embodiment is performed by a conference pipe in the node apparatus.

In this embodiment, when the original old active node fails, each participant terminal in the interrupted video conference may exit the video network, so the node device needs to spend a certain time to wait for each participant terminal to access the video network, then wait for the participant terminal that successfully accesses the network to join the video conference, and then start the video conference, and after starting the video conference, the whole interrupted conference service is completely recovered.

However, the conference management programs deployed in all the node devices are the same program, and the conference management does not know which server the old active node with the fault is (only the network management knows), so in some scenes, after the conference management of the node devices recovers the conference data of the video networking video conference, the participant terminals are directly pulled into the video networking video conference and start the conference, and some participant terminals exiting from the video networking cannot join the video networking video conference because they have not come into the network. Therefore, the effect of recovering the interrupted conference service is not ideal.

The method of the embodiment can well solve the problem. Under different activation types, the time length required when the participant terminal exits the video network and then accesses the network is different, so that different delay waiting time lengths are set for different activation types, in the delay waiting time length, the node equipment can wait for the participant terminal exiting the video network to access the network, the participant terminal which successfully accesses the network can be waited to join the video network video conference, and when the delay waiting time length is over, the video network video conference is started, so that the probability that the participant terminal cannot join the video network video conference due to non-access to the network can be reduced, and the recovery effect of the interrupted conference service is integrally improved.

In this embodiment, the participant terminal may actively join the video conference (the participant terminal actively sends a conference joining request to the node device and joins the conference after obtaining permission), or join the video conference in response to a conference invitation of the node device. When the node equipment sends the conference invitation to the participating terminals, the node equipment can periodically send the conference invitation, thereby ensuring that the participating terminals can smoothly join the video conference of the video network with the maximum probability. The method for adding the video networking video conference into the conference participating terminal is not particularly limited.

The delay waiting time lengths corresponding to different activation types may be set according to actual requirements, and this embodiment does not specifically limit this.

In the embodiment, different delay waiting time lengths are set for different activation types, so that the probability that the participant terminal cannot join the video conference of the video network because the participant terminal is not connected to the video conference can be reduced, and the recovery effect of the interrupted conference service is integrally improved.

With reference to the foregoing embodiment, in an implementation manner, the present application further provides another conference resuming policy, and on this basis, resuming the video conference on the node device according to the conference resuming policy corresponding to the activation type may specifically include the following steps:

In this embodiment, after the failure of the original active node occurs, the participating terminal may exit the video network. After the participant terminal exits the video networking, the participant terminal automatically initiates a network access request to the autonomous system, and the autonomous system completes network access operation. After a certain participant terminal successfully accesses the network, the autonomous system sends a network access success notification to the conference manager, the conference manager waits for the participant terminal which successfully accesses the network to join the video conference on the video network, if the participant terminal successfully joins the video conference on the video network, the conference manager receives the successful conference access notification sent by the participant terminal, and when the successful conference access notification sent by all the participant terminals is received, all the participant terminals are determined to join the video conference on the video network. If the participant terminal does not exit the video networking after the original active node fails, the conference manager can directly wait for the participant terminal to join the video networking video conference, and determines that all the participant terminals join the video networking video conference when receiving the successful conference entering notification sent by all the participant terminals.

In this embodiment, in order to prevent that the video conference on the internet cannot be started when the successful notification of the access of a certain participant terminal is not received, a preset time duration may be set. If the conference receiver receives the successful conference-entering notification sent by all the participant terminals within the preset time length, the conference receiver can start the video conference of the video network at the moment that the last participant terminal joins the video conference of the video network without waiting for the preset time length to finish. If the conference tube does not receive the successful notification of conference entrance sent by a certain conference participating terminal all the time when the preset time length is over, the conference tube can directly start the video networking video conference without waiting for the conference participating terminals which do not join the conference, and the normal operation of the video networking video conference is ensured.

In this embodiment, can open the video conference of video network when all meet terminals all join the video conference of video network, realized opening the video conference of video network according to the developments of each meeting terminal of participating in, promoted the flexibility that the meeting was resumeed.

In specific implementation, the conference recovery policy may be set arbitrarily for different activation types, for example, a first conference recovery policy may be set for the activation type of the master-slave switching, and a second conference recovery policy may be set for the slave-slave switching and the slave-master switching. The first conference recovery policy may also be directly set for all the activation types, and may be specifically set according to actual requirements, which is not limited in this application.

With reference to the foregoing embodiment, in an implementation manner, the present application further provides a method for determining a delay waiting duration corresponding to an activation type, where the method specifically includes:

when the activation type is the main-standby switching, determining that the delay waiting time length is a first time length, wherein the first time length comprises the conference entering time length of the conference participating terminal;

and when the activation type is the slave-master switching, determining that the delay waiting time is a third time, wherein the third time comprises a detection time, the network access time of the participant terminal and the conference access time, and the detection time is used for detecting whether the heartbeat connection between the master node and the standby node is disconnected.

In this embodiment, under different activation types, the time lengths required by each participant terminal from exiting the video network to joining the video network video conference are different, specifically, the first time length is less than the second time length, and the second time length is less than the third time length.

When the activation type is master-slave switching, because a dual-master hot-standby mechanism is configured between the master node and the slave node, and autonomous systems on two node devices are connected with the same comprehensive management server, each participant terminal does not need to quit the video network, and a video network video conference can be rapidly added to the slave node, so that the first time duration needs to include the conference entering time duration of the participant terminal.

When the activation type is slave switching, the participant terminal has a process of network quitting and network accessing, and the participant terminal can not join the video network video conference until the network accessing is successful. Therefore, the second duration needs to include the network access duration and the session access duration of the participant terminal.

When the activation type is the slave-master switching, because a dual-master hot-standby mechanism is adopted between the master node and the slave node, the autonomous system of the slave node has a process of detecting whether the master node is out of step (whether heartbeat connection between the autonomous systems of the master node and the slave node is disconnected), the participant terminal is loaded to access the network after the process is finished, and the participant terminal can be added to the video conference after the participant terminal is successfully accessed to the network. Therefore, the third duration needs to include the detection duration, the network access duration of the participant terminal, and the conference access duration.

In the embodiment, different delay waiting durations are set for each activation type according to different durations required when the participant terminal quits the video networking and then adds the video networking video conference, so that the probability that the participant terminal cannot add the video networking video conference due to not accessing the network can be reduced, and the recovery effect of the interrupted conference service is integrally improved.

With reference to the foregoing embodiments, in one implementation, a first type heartbeat connection is established between node devices in a video networking network; on this basis, the conference resuming method of the present application may further include:

detecting whether a first type of heartbeat connection with an original active node of a video conference of the video network is disconnected or not;

when the first type of heartbeat connection is disconnected, the node device is determined to be required to be activated as an active node in the video networking network.

In this embodiment, a first type of heartbeat connection is established between the network managers of each node device in the video network.

In specific implementation, for a certain node device X, when detecting that a first-class heartbeat connection between network managers of some other node device Y is disconnected, it may be determined that the node device Y fails, then, the node device X may determine whether the node device Y is an active node by checking a node configuration file of the failed node device Y, if the node device Y is an active node, the node device X determines whether the node device X is a new active node (a node device that replaces the failed active node device Y) according to a preset activation sequence, if so, obtains a type of the node device Y according to the node configuration file of the node device Y, obtains the type of the node device X according to the node configuration file of the node device X, and obtains a correspondence between the type of the node device Y, the type of the node device X, and the activation type and the type of the node device, the activation type is determined.

In specific implementation, the network manager of the node device may detect whether the first type heartbeat connection with the old active node is disconnected, and if the first type heartbeat connection with the old active node is disconnected, it is determined that the old active node has a failure and needs to be switched to a new active node. At the moment, the network manager reads the node configuration file of the old active node, determines the role of the new active node according to the node configuration file of the network manager, and writes the roles of the old active node and the new active node into the shared file. And sending the shared file to a meeting manager of the node equipment, and determining the activation type by the meeting manager of the node equipment according to the shared file and the corresponding relation.

In this embodiment, by establishing the first type of heartbeat connection between the network managers of each node device, the lower level node device can quickly detect whether a failure occurs according to the first type of heartbeat connection between the lower level node device and the active node, so that the failure detection efficiency can be improved, and the conference recovery efficiency can be further improved.

With reference to the foregoing embodiment, in an implementation manner, a second heartbeat connection is further maintained between the master node and the network manager of the standby node, where the second heartbeat connection is different from the first heartbeat connection. On this basis, when the delay waiting time is not reached, the method of the present application may further include:

if the activation type is master-slave switching, waiting for the participant terminal to join the video conference of the video network within the conference joining time;

if the activation type is slave switching, waiting for the participant terminal to access the network within the network access duration, and waiting for the participant terminal successfully accessing the network to join the video network video conference within the network access duration;

and if the activation type is the slave-master switching, detecting whether the second heartbeat connection is disconnected within the detection time length, if the second heartbeat connection is disconnected, waiting for the participant terminal to access the network within the network access time length, and waiting for the participant terminal successfully accessing the network to join the video conference of the video network within the network access time length.

In this embodiment, because a dual-computer hot-standby mechanism is adopted between the main node and the standby node, a second type of heartbeat connection (dual-computer hot-standby heartbeat connection) different from the first type of heartbeat connection (network management heartbeat connection) is also established between the main node and the standby node.

For the active-standby switching, because a dual-host hot-standby mechanism is configured between the master node (for example, server a1 in fig. 1) and the standby node (for example, server a2 in fig. 1), and the same video network server (integrated management server a) connected with the autonomous systems on the two servers can quickly switch the participant terminal to the standby node, the participant terminal will not exit the video network during the switching, and the speed is fastest and is about 2 seconds. Therefore, for the master-slave switching, the corresponding delay waiting time length can be set to be 2 seconds, and the participating terminal in the video networking conference waiting for interruption joins the video networking video conference within the delay waiting time length. And when the delay waiting time length is over, starting the video conference of the video network. For the slave switching, the terminal has a process of exiting the video network and then entering the video network, so the terminal can not join the video conference of the video network until the terminal enters the video network, and the speed is low and is about 30 seconds. Therefore, for the slave switching, the corresponding delay waiting time length can be set to be 30 seconds, and then the delay waiting time length is divided into the network access time length and the conference access time length. Firstly, waiting for the joining terminal to join the network within the network joining duration, and then waiting for the joining terminal which successfully joins the network to join the video conference of the video network within the network joining duration. And when the delay waiting time length is over, starting the video conference of the video network. For the slave-master switching, since a dual-master hot-standby mechanism of the master node or the standby node is involved, a process of detecting whether the second-type heartbeat connection between the master node and the standby node is disconnected exists. The terminal is loaded to enter the network after the process is finished, so that the time for switching from the master is slowest, about 70 seconds. Therefore, for the slave-master switching, the corresponding delay waiting time length can be set to 70 seconds, then the delay waiting time length is divided into a detection time length, a network access time length and a conference access time length, whether the second type heartbeat connection is disconnected or not is detected within the detection time length, if the second type heartbeat connection is disconnected, the conference access of the participant terminal is waited within the network access time length, and then the participant terminal which is waited to be successfully accessed is accessed to the video conference in the conference access time length. And when the delay waiting time length is over, starting the video conference of the video network.

No matter which activation type is adopted, when the participating terminal joins the video networking conference, the participating terminal can actively send a conference joining request to the node equipment and join the video networking conference, and can wait for the node equipment to send a conference invitation and join the video networking conference. For the slave-master switching and the slave switching, because the participant terminal has a process of breaking and then accessing the network, the node equipment does not know when the participant terminal successfully accesses the network, therefore, if the mode of sending the conference invitation by the node equipment is adopted, the node equipment can send the conference invitation at regular intervals, thereby ensuring that the participant terminal can successfully join the video conference of the video network with the maximum probability. In the embodiment, different delay waiting durations are set for each activation type according to different durations required when the participant terminal quits the video networking and then adds the video networking video conference, so that the probability that the participant terminal cannot add the video networking video conference due to not accessing the network can be reduced, and the recovery effect of the interrupted conference service is integrally improved.

Fig. 3 is a process diagram illustrating a conference resuming method according to an embodiment of the present application. The conference resuming method of the present application will be described in detail with reference to fig. 3.

In fig. 3, when detecting that a first type of heartbeat connection between a network manager in a node device and a network manager of an old active node is disconnected (for example, a heartbeat disconnection may be caused by a downtime of the old active node), it is determined that the old active node has a failure and an active node needs to be switched (that is, a new active node needs to be activated).

The network manager in the node equipment reads the node configuration file of the old active node to obtain the role of the old active node, then obtains the role of the new active node (node equipment) according to the node configuration file of the network manager, and then writes the role of the new active node and the old active node into the network management role switching file (shared file).

And the network manager in the node equipment sends the network management role switching file to a meeting manager in the node equipment.

The meeting manager in the node equipment reads the network management role switching file and judges the activation type according to the roles of the new and old active nodes.

And the conference pipe in the node equipment determines the delay waiting time (the master-slave switching is 2s, the slave switching is 30s, and the slave switching is 70s) according to the activation type.

And in the time of the delay waiting time, the conference management in the node equipment waits for each participant terminal to access the network, and after the network access is finished, the participant terminal which is successfully accessed to the network joins the video networking video conference, and the video networking video conference is started, so that the recovery of the interrupted video networking service is finished.

In the application, the plurality of node devices may be composed of a plurality of servers distributed in different regions, wherein the master node and the standby node are hot-standby by a master server and a standby server, and a plurality of slave nodes (a/B/C/…) are added to form multi-point survivability. At the same time, only one of the node devices is an active node, when a certain active node is destroyed, the network manager in the new active node deactivates the new active node according to the hot standby priority order (for example, main > standby > C > B > A > …), the conference manager in the new active node judges the activation type according to the shared file sent by the network manager, and resumes the conference on the new active node. The databases on the servers are synchronous in real time, so that the data consistency of each node can be ensured, and the conference service can be conveniently recovered through the data stored in the databases. According to the method and the device, different delay waiting time lengths are set for different activation types, so that the probability that the participant terminal cannot join the video network video conference due to not accessing the network can be reduced, and the recovery effect of the interrupted conference service is integrally improved.
