Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

To enable those skilled in the art to better understand the embodiments of the present invention, the following description refers to an autonomous network in a video network:

referring to fig. 2, a schematic structural diagram of an autonomous network of an internet of view according to an embodiment of the present invention is shown.

As shown in fig. 2, the autonomous network of the internet of view is a distributed centralized control network, and the autonomous network includes a plurality of autonomous clouds distributed in layers, that is, the overall network structure of the autonomous network of the internet of view is formed by connecting a plurality of substructures called autonomous clouds, and the autonomous clouds are in a hierarchical structure when connected with each other.

Each autonomous cloud can be connected with one or more next-layer autonomous clouds from the top-layer autonomous cloud, the lower-layer autonomous clouds are connected with the next-layer autonomous clouds until the lowest-layer autonomous cloud, and all the autonomous clouds are connected layer by layer in the mode to form an autonomous network.

Obviously, the hierarchical structure is a tree structure, and the whole autonomous network is a tree composed of a plurality of autonomous clouds.

As shown in fig. 2, the autonomous network may include four layers, an autonomous cloud in a fourth layer (L4) connecting autonomous clouds in a plurality of third layers (L3), an autonomous cloud in a third layer (L3) connecting autonomous clouds in a plurality of second layers (L2), and an autonomous cloud in a second layer (L2) connecting autonomous clouds in one or more first layers (L1).

Referring to fig. 3, a schematic diagram of a network architecture of an autonomous cloud according to an embodiment of the present invention is shown.

In the embodiment of the invention, in order to improve the survivability of the autonomous cloud of the video networking and avoid the condition that the autonomous cloud as a whole fails when an autonomous server or a network management server in the autonomous cloud fails, so that the autonomous cloud can still keep the normal operation of the rest equipment under the condition that part of the equipment fails, the embodiment of the invention can adopt an autonomous cloud network architecture as shown in fig. 3, and the network architecture of the autonomous cloud can comprise at least one main node and at least two slave nodes which are in communication connection with the main node.

The master node may be configured to manage slave nodes in the autonomous cloud and communicate with other autonomous clouds. Specifically, the master node may manage and register the slave nodes in the autonomous clouds, thereby implementing the video networking service logic inside the autonomous clouds and between the autonomous clouds and the network communication management of the video networking.

The slave nodes can be used for providing specific video networking services for video networking terminals accessed into the autonomous cloud based on the management of the master nodes. For example, video networking audio data and video networking video data forwarding, control of video networking terminals, registration, etc.

As a specific example of the present invention, the video networking terminal accessed from the slave node to the autonomous cloud may be a video networking conference set-top box, a video telephone set-top box, an operation teaching set-top box, a video networking streaming media gateway, a video networking media synthesizer, and the like, which is not limited in this respect.

Optionally, the network architecture of the autonomous cloud may include at least one standby node, and the standby node is in communication connection with the master node; the backup node is pre-configured to synchronously acquire the autonomous cloud management data and the network management data of the master node. And under the condition that the main node fails, the standby node can become a new main node, and the slave node and the video networking terminal accessed to the autonomous cloud are continuously controlled to perform video networking service interaction by adopting the autonomous cloud management data and the network management data of the main node, so that switching between the main node and the standby node is realized, and stable operation of the autonomous cloud is ensured.

In a specific implementation, fig. 4 is a schematic diagram of a hardware architecture of an autonomous cloud according to an embodiment of the present invention. The autonomous cloud may include at least one master node and at least two slave nodes.

The master node may include at least one master server and at least one network management server. The master control server and the network management server in the master node can communicate with each other. The master control server in the master node can be used for managing and registering the equipment in the autonomous cloud, and managing services such as video networking service interaction, network communication management and the like in the autonomous cloud and among the autonomous clouds. And the network management server in the main node is used for controlling management services such as service opening, registration and the like of the slave nodes in the autonomous cloud through the main control server in the main node, and simultaneously providing a calling interface for the outside of the autonomous cloud.

The slave nodes can comprise a master control server, a network management server and a sub-control server. The master control server in the slave node may be configured to perform management services such as management, registration, network communication management, and the like on the sub-control servers in the slave node based on the management of the master node. The network management server in the slave node can be used for management based on the master node, and the master control server in the slave node controls management services such as service opening and registration of the sub-control server in the slave node. The sub-control server in the slave node can be used for providing video networking services for the video networking terminal, such as video networking audio and video forwarding, video networking set-top box control, registration and the like.

Optionally, the autonomous cloud may further include at least one standby node. The standby node may include at least one master server and at least one network management server. The master control server in the standby node and the network management server in the standby node are communicated with each other, meanwhile, the master control server in the standby node can be communicated with the master control server in the main node to synchronously acquire the autonomous cloud management data of the master control server in the main node, and the network management server in the standby node can be communicated with the network management server in the main node to synchronously acquire the network management data of the network management server in the main node. Therefore, when the master node fails, the standby node can take over the slave nodes in the autonomous cloud to continue to be managed by the master node based on the autonomous cloud management data and the network management data synchronously acquired by the slave master node.

As an optional implementation manner in the present invention, the master control server and the network management server of the master node may be integrated into a first integrated device. If the backup node needs to be set in the autonomous cloud, the master control server and the network management server of the integrated master node and the master control server and the network management server of the backup node can be integrated into the first integrated device. In addition, the master control server, the network management server and the sub-control servers of the slave nodes can be integrated into a second integrated device. Therefore, under the condition that the autonomous cloud needs to be established, the establishment of the autonomous cloud can be quickly completed by establishing at least one first integrated device and at least one second integrated device as the autonomous cloud.

Referring to fig. 5, a flowchart illustrating steps of an embodiment of a survivability method based on an autonomous cloud network architecture of the video networking of the present invention is shown, wherein the network architecture of the autonomous cloud comprises at least one master node and at least two slave nodes; the slave node is in communication connection with the master node; the master node is used for managing the slave nodes in the autonomous cloud and communicating with other autonomous clouds, and the slave nodes are used for providing video networking services for video networking terminals accessed into the autonomous cloud based on the management of the master node.

If the video networking terminal needs to be accessed into the autonomous cloud to obtain the video networking service provided by the autonomous cloud, the video networking terminal can be accessed into the autonomous cloud through an interface provided by a main node in the autonomous cloud, then the main node in the autonomous cloud can distribute a slave node for the video networking terminal, and the slave node can provide the video networking service for the video networking terminal accessed into the autonomous cloud based on the management of the main node.

The method comprises the following steps:

step 501, the slave node determines whether the master node fails;

in the embodiment of the invention, in order to ensure that the autonomous cloud can normally operate, the slave node may determine whether the master node fails to determine whether the autonomous cloud can still maintain normal operation.

In an alternative embodiment, the master node may actively send the survival notification signaling to the slave node with a preset period. The liveness notification signalling may be used to inform the slave nodes that the master node is still active, so that the slave nodes may determine that the master node has not failed in case of receiving the liveness notification signalling. If the master node has not sent the survival notification signaling to the slave node for a period of time, the slave node may determine that the master node has failed.

In another alternative embodiment, the master node may not actively send the survival notification signaling, and the slave node sends the survival inquiry signaling with a preset period to inquire whether the master node still operates normally. If the master node is operating normally, the master node may return response information corresponding to the survival inquiry signaling. And if the main node fails, the main node cannot return response information corresponding to the survival inquiry signaling. If the slave node does not receive the response information after sending the survival inquiry signaling for a certain period of time, it can be determined that the master node has failed.

Step 502, if the slave node determines that the master node fails, the slave node sends node priority information to other slave nodes in the autonomous cloud, and receives the node priority information sent from the other slave nodes to the slave node;

in the embodiment of the invention, if the slave node determines that the master node fails, the autonomous cloud cannot be normally used at the moment. In order to ensure that the autonomous cloud can still maintain normal operation to a certain degree under the condition that the master node fails, a new master node can be selected from slave nodes of the autonomous cloud, and the new master node is used for continuously managing the slave nodes in the autonomous cloud, so that the slave nodes can continuously provide video networking services for video networking terminals accessed into the autonomous cloud.

In the embodiment of the present invention, the nodes in the autonomous cloud may have a preset node priority. In the case of a failure of the master node, the slave node with the higher node priority can take over the autonomous cloud preferentially, so that in the case of a failure of the master node, the slave node which can be used as a new master node is determined quickly.

Therefore, the slave nodes which detect the failure of the master node in the autonomous cloud can send node priority information to other slave nodes in the autonomous cloud. The node priority information may be recorded with the node priority of the slave node. The node priority may be preset during the process of establishing the autonomous cloud. Specifically, the node priority may be configured based on the device performance used by the node, may also be configured based on the order in which the nodes are grouped into the autonomous cloud, and may also be configured based on the service to be processed by the node in the autonomous cloud, and the like, which is not limited in the present invention.

Therefore, for a slave node, the slave node can send node priority information to other slave nodes in the autonomous cloud, and can also receive the node priority information sent by other slave nodes to the slave node.

Step 503, the slave node selects a new master node to take over the slave node in the master node management autonomous cloud with the fault based on the node priority information sent by other slave nodes and the node priority information of the slave node;

in the embodiment of the invention, after the slave node obtains the node priority information sent by other slave nodes, a new master node can be selected based on the node priority information sent by other slave nodes and the node priority information of the slave node, and the new master node can be used for taking over the slave node in the management autonomous cloud which has a fault originally, so that the autonomous cloud can be ensured to be taken over by the slave node in the autonomous cloud after the master node has the fault, and the autonomous cloud is ensured to maintain normal operation.

Specifically, the slave node analyzes the node priority information transmitted from the other slave nodes, and knows the node priorities of the other slave nodes. Then, the slave nodes can compare the node priority of the slave nodes with the node priority of other slave nodes to determine a target slave node suitable for becoming a new master node, so that the new master node can be selected from the slave nodes of the autonomous cloud to take over the slave nodes in the autonomous cloud managed by the original master node with a fault.

And step 504, the new master node manages the slave nodes in the autonomous cloud, and the slave nodes in the autonomous cloud are controlled to continue to provide the video networking service for the video networking terminals accessed into the autonomous cloud.

In the embodiment of the invention, after the new master node is determined, the new master node can take over the original faulty master node, manage the slave nodes in the autonomous cloud, control the slave nodes in the autonomous cloud to continue to provide the video networking service for the video networking terminals accessed into the autonomous cloud, and ensure the normal operation of the autonomous cloud. The slave nodes in the autonomous cloud can continue to provide video networking services for the video networking terminals accessed into the autonomous cloud based on the management of the new master node, so that the autonomous cloud can still keep normal operation to a certain degree after the master node fails, and the survivability of the video networking autonomous cloud is improved.

According to the anti-destruction method based on the video networking autonomous cloud network architecture, the slave node determines whether the master node fails or not so as to determine whether the autonomous cloud can maintain normal operation or not. If the slave node determines that the master node fails, the slave node sends node priority information to other slave nodes in the autonomous cloud, and receives the node priority information sent by the other slave nodes to the slave node, so that the slave node which can take over the failed master node is selected from the slave nodes of the autonomous cloud under the condition that the autonomous cloud cannot normally operate. The slave nodes select a new master node to take over the slave nodes in the master node management autonomous cloud with faults based on node priority information sent by other slave nodes and the node priority information of the slave nodes; the new master node manages the slave nodes in the autonomous cloud and controls the slave nodes in the autonomous cloud to continue providing the video networking service for the video networking terminal accessed into the autonomous cloud, so that the autonomous cloud can still keep normal operation to a certain degree after the master node fails, and the survivability of the video networking autonomous cloud is improved.

Referring to fig. 6, a flowchart illustrating steps of an embodiment of a survivability method based on an autonomous cloud network architecture of the video networking of the present invention is shown, wherein the network architecture of the autonomous cloud comprises at least one master node and at least two slave nodes; the slave node is in communication connection with the master node; the master node is used for managing the slave nodes in the autonomous cloud and communicating with other autonomous clouds, and the slave nodes are used for providing video networking services for video networking terminals accessed into the autonomous cloud based on the management of the master node.

The method comprises the following steps:

601, the slave node determines whether the master node fails;

Step 602, if the slave node determines that the master node fails, the slave node sends node priority information to other slave nodes in the autonomous cloud, and receives node priority information sent from other slave nodes to the slave node.

Therefore, if the slave node determines that the master node fails, the slave node can send node priority information to other slave nodes in the autonomous cloud and receive the node priority information sent by the other slave nodes to the slave node.

In one embodiment of the present invention, the step of sending node priority information from the slave node to other slave nodes in the autonomous cloud, and receiving node priority information sent from other slave nodes to the slave node, includes:

s11, the slave node sends election signaling recorded with node priority information of the slave node to other slave nodes in the autonomous cloud, and receives the election signaling recorded with node priority information of other slave nodes sent by other slave nodes; the election signaling is used for informing the node receiving the election signaling, and the node sending the election signaling participates in the main node election; the master node election is used for selecting a new master node from the nodes of the autonomous cloud;

in the embodiment of the invention, the slave nodes in the autonomous cloud can adopt a master node election mode to select a new master node from a plurality of slave nodes in the autonomous cloud. Meanwhile, the nodes in the autonomous cloud may have a preset node priority. In the case of a failure of the master node, the slave node with the higher node priority can take over the autonomous cloud preferentially, so that in the case of a failure of the master node, the slave node which can be used as a new master node is determined quickly.

Therefore, all the slave nodes which wish to participate in election in the autonomous cloud can send election signaling recorded with the priority information of the slave node to other slave nodes in the autonomous cloud so as to inform the receiving end of the slave nodes, and the sending end of the slave nodes participates in the master node election.

Therefore, the slave node can send the election signaling in which the node priority information of the slave node is recorded to other slave nodes in the autonomous cloud, meanwhile, the election signaling sent by other slave nodes needing to participate in the election of the master node can be received, and then the slave node can analyze the election signaling sent by other slave nodes to obtain the node priority information of other slave nodes.

In a specific implementation, in the process of establishing the autonomous cloud, a network address may be configured for a node based on a node priority of the node. For example, a node with a higher node priority may be configured to have a network address with a smaller value, such that the network address of the node may be 1.0.0.0, 1.0.0.1, 1.0.0.2, 1.0.0.3 … …, from high node priority to low node priority. For example, if the slave node has a network address of 1.0.0.2 and the received election signaling corresponds to a node having a network address of 1.0.0.1, the slave node may determine that the node having a network address of 1.0.0.1 has a higher node priority than itself.

In particular, a master node election in an autonomous cloud may not have the process of notifying all slave nodes to enter an election state to participate in the election. After determining that the master node is faulty, each slave node in the autonomous cloud can directly send election signaling to other slave nodes in the autonomous cloud to inform the receiving end of the slave node, and the sending end of the slave node participates in master node election. The receiving slave node may or may not have determined that the master node failed and also sent election signaling. In case the receiving slave node does not determine that the master node is down and receives election signaling. The receiving slave node may determine whether the master node has failed and may also send election signaling after determining that the master node has failed. Therefore, the autonomous cloud can determine whether the master node election needs to be carried out or not by the slave node without additionally informing all the slave nodes to enter the election state to participate in the election, and directly enters the election state to send the election signaling.

In an embodiment of the present invention, the network architecture of the autonomous cloud further includes at least one standby node, and the standby node is in communication connection with the master node; the backup node is pre-configured to synchronously acquire the autonomous cloud management data and the network management data of the master node;

in the embodiment of the present invention, the network architecture of the autonomous cloud may further include at least one standby node. The standby node may be communicatively coupled to the primary node. In the normal operation process of the main node, the backup node can synchronously acquire the autonomous cloud management data and the network management data of the main node, so that the backup of the main node is realized. And under the condition that the main node fails, the standby node can take over the main node to manage the slave nodes in the autonomous cloud.

The method further comprises the following steps:

s21, if the slave node determines that the master node has a fault, the slave node also sends node priority information to the standby node and receives the node priority information sent by the standby node to the slave node;

in the embodiment of the present invention, when a backup node exists in the autonomous cloud, the slave node determines that the master node has a failure, and the slave node may further send node priority information to the backup node. Meanwhile, the standby node can also detect that the main node fails and send node priority information to the slave nodes in the autonomous cloud. So that the slave node can also receive node priority information sent by the slave node to the slave node.

The method comprises the following steps that a slave node selects a new master node to take over a failed master node to manage slave nodes in an autonomous cloud based on node priority information sent by other slave nodes and node priority information of the slave node, and comprises the following steps:

and S31, the slave node selects a new master node to take over the slave node in the master node management autonomous cloud with the fault based on the node priority information sent by other slave nodes, the node priority information sent by the standby node and the node priority information of the slave node.

In the embodiment of the present invention, when the slave node receives the node priority information sent by the standby node, the slave node may select a new master node based on the node priority information sent by other slave nodes, the node priority information sent by the standby node, and the node priority information of the slave node. Therefore, under the condition that the main node fails, the standby node can take over the failed main node to manage the slave nodes in the autonomous cloud in a mode of sending node priority information.

In a specific implementation, the priority of the standby node may be preset to be higher than that of the slave node and lower than that of the master node. Therefore, if the standby node participates in the selection of the new master node, the standby node can be prior to the slave node to become the new master node, and therefore the standby node backed up with the master node and the network management data can be preferentially used for taking over the autonomous cloud.

In a specific implementation, the standby node may participate in the selection of the new master node in the following manner:

s41, the standby node determines whether the main node has a fault;

in the embodiment of the present invention, the standby node may determine whether the master node fails to determine whether the autonomous cloud can still maintain normal operation.

In a specific implementation, the standby node may receive the survival notification signaling of the primary node by using a preset period, and determine whether the primary node fails based on whether the survival notification signaling of the primary node is received. The standby node can also actively adopt a preset period to send a survival inquiry signaling to inquire whether the main node still normally operates or not so as to determine whether the main node fails or not.

S42, if the backup node determines that the master node fails, the backup node sends node priority information to the slave nodes in the autonomous cloud, and receives the node priority information sent by the slave nodes to the backup node;

in the embodiment of the invention, if the backup node determines that the master node fails, in order to ensure that the autonomous cloud can still maintain normal operation to a certain degree under the condition that the master node fails, the backup node sends node priority information to the slave nodes in the autonomous cloud, receives the node priority information sent from the slave nodes to the backup node, and becomes a new master node in the autonomous cloud in a master node election mode.

And S43, the standby node selects a new main node based on the node priority information sent by other slave nodes and the node priority information of the standby node.

In the embodiment of the present invention, after obtaining the node priority information sent by other slave nodes, the standby node may select a new master node from the slave nodes of the autonomous cloud based on the node priority information sent by other slave nodes and the node priority information of the standby node itself, so as to take over the master node with the original fault to manage the slave nodes in the autonomous cloud.

In a specific implementation, the priority of the standby node may be preset to be higher than that of the slave node and lower than that of the master node. Therefore, under the condition that the standby node participates in the master node election, the standby node can be a new master node in preference to the slave node, and therefore the standby node which backups the autonomous cloud management data of the master node and the network management data can be used for taking over the autonomous cloud preferentially.

Step 603, the slave node selects the slave node with the highest node priority as a new master node for taking over the slave node in the original faulty master node management autonomous cloud based on the node priority information sent by other slave nodes and the node priority information of the slave node;

in the embodiment of the present invention, after obtaining the node priority information sent by other slave nodes, the slave node may select a node with the highest node priority as a new master node based on the node priority information sent by other slave nodes and the node priority information of the slave node itself, so as to take over the slave node in the management autonomous cloud of the original master node with the fault.

Specifically, the slave node learns the node priorities of the other slave nodes based on the node priority information transmitted from the other slave nodes. Then, the slave node may compare the node priority of the slave node with the node priorities of other slave nodes, determine a target master node with the highest node priority, and use the target master node as a new master node to take over the slave node in the management autonomous cloud of the original master node with the fault.

In an embodiment of the present invention, the step of selecting, by a slave node, a slave node with the highest node priority as a new master node based on node priority information sent by other slave nodes and node priority information of the slave node, includes:

s51, the slave node determines whether the node priority of the slave node is higher than the node priorities of other slave nodes according to the node priority information sent by the slave node and the received node priority information sent by other slave nodes;

in the embodiment of the present invention, the slave node may determine whether or not it can become a new master node based on the node priority information described in the node priority information and transmitted by itself and the node priority information transmitted by the other slave nodes. Therefore, the slave nodes can determine whether the node priorities of the slave nodes are all higher than the node priorities of other slave nodes so as to determine whether the slave nodes can become a new master node.

S52, if the node priorities of the slave nodes are all higher than the node priorities of other slave nodes, the slave nodes determine that the slave nodes are new master nodes and send master node notification signaling to other slave nodes in the autonomous cloud; the master node notification signaling is used to notify the slave node that will send the master node notification signaling as a new master node.

In the embodiment of the present invention, if the node priorities of the slave nodes are all greater than the node priorities of the other slave nodes, the slave node may determine that the slave node is a slave node with the highest node priority from the slave nodes participating in the master node election, and in this case, the slave node may determine that the slave node is a new master node and send a master node notification signaling to the other slave nodes in the autonomous cloud.

The master node notification signaling may be used to notify a node that will send the master node notification signaling as a new master node.

Thus, after receiving the master node notification signaling, the other slave nodes can take the master node that transmitted the master node notification signaling as a new master node and wait for receiving the management of the new master node.

And S53, if the node priority of the slave node is not greater than the node priority of any other slave node, the slave node waits for other slave nodes to send the master node notification signaling.

In the embodiment of the present invention, if the node priority of the slave node is not greater than the node priority of any other slave node, the node priority of the slave node may be considered to be lower and cannot become a new master node, and at this time, the slave node waits for the other slave nodes to send a master node notification signaling to wait for receiving management of the new master node.

In an embodiment of the present invention, if the new master node is a slave node, the method further includes:

s61, the new master node starts the network management function by adopting the preset network management data;

in the embodiment of the invention, under the condition that the new master node does not have the autonomous cloud management data, the new master node needs to adopt other modes to take over the autonomous cloud. In this case, the new master node may start its own network management function using the preset gateway data.

In a specific implementation, network management data may be stored in advance in a node in the autonomous cloud, and the network management data may include necessary data required for the node to manage other slave nodes in the autonomous cloud. The new master node can start the network management function of itself by adopting the network management data, so that the new master node can have the function of managing other slave nodes.

S62, the new master node sends an autonomous recovery instruction to other slave nodes in the autonomous cloud; the autonomous recovery signaling is used for indicating a slave node in the autonomous cloud to recover the original working state;

in the embodiment of the present invention, after the network management function is started, the new master node needs to restore the working states of other slave nodes in the autonomous cloud, so that the autonomous cloud can restore normal operation. Therefore, the new master node can send an autonomous recovery signaling to other slave nodes in the autonomous cloud, and the autonomous recovery signaling is used for indicating the other slave nodes in the autonomous cloud to recover the original working state.

In a specific implementation, the autonomous recovery signaling may be used to instruct other slave nodes in the autonomous cloud to recover user information of a node accessed in the autonomous cloud, recover normal operation of a device in the autonomous cloud, recover configuration information of a node in the autonomous cloud, and the like, which is not limited in this respect. Therefore, after other slave nodes in the autonomous cloud receive the autonomous reply signaling, the other slave nodes can continue to operate according to the working state before the original main node fails.

And S63, the new master node takes over the slave nodes in the original master node management autonomous cloud so as to control the slave nodes to continue to provide the video networking service for the video networking terminals accessed into the autonomous cloud.

In the embodiment of the invention, after determining that other slave nodes in the autonomous cloud have recovered the original working state, the new master node can be used as the master node to control the slave nodes to perform video networking service interaction with other video networking equipment, so that the slave nodes are managed as the master node to control the slave nodes to continue to provide the video networking service for the video networking terminals accessed into the autonomous cloud.

In an embodiment of the present invention, if the new master node is a standby node, the step of managing the slave nodes in the autonomous cloud by using the new master node and communicating with other autonomous clouds includes:

and S71, the new master node manages the slave nodes in the autonomous cloud by adopting the autonomous cloud management data and the network management data.

In the embodiment of the invention, if the standby node is a target node serving as a new main node, the standby node can synchronously acquire the autonomous cloud management data of the main node in the operation process of the main node, so that the standby node does not need to acquire the autonomous cloud management data additionally, but can directly adopt the autonomous cloud management data to control the slave node to provide the video networking service for other video networking equipment accessing the autonomous cloud.

The other video networking devices may be video networking terminals accessing the autonomous cloud, video networking devices of other autonomous clouds, video networking devices of other slave nodes in the autonomous cloud, and the like, which is not limited in the present invention.

In one embodiment of the invention, the method further comprises:

s72, if the video network terminal accesses the autonomous cloud, the new master node sends a service recovery instruction to the video network terminal; and the service recovery instruction is used for indicating the video networking terminal to recover the interrupted video networking service.

In the embodiment of the invention, after the main node of the autonomous cloud fails, the video networking terminal may be disconnected from the node in the autonomous cloud, so that the video networking service is interrupted. The nodes in the autonomous cloud can continue to retain data generated by video networking service interaction between the slave nodes and the video networking terminals. Such as data generated by video networking services like video telephony, live distribution, live viewing, video conferencing, etc. And then, taking over the autonomous cloud by the new main node, and after the autonomous cloud is recovered to be normal, the video networking terminal can be accessed into the autonomous cloud again. At this time, in order to enable the terminal to recover the video networking service which is originally in progress, the new master node may send a service recovery instruction to the video networking terminal to prompt the video networking terminal to recover the interrupted video networking service. After the video networking terminal receives the service restoring instruction, if the video networking terminal has the interrupted video networking service, the video networking terminal can try to restore the original communication with the autonomous cloud, so that the interrupted video networking service is restored. And if the video networking service is the video conference service, the conference management server of the main node assists in recovering the video conference service. If the video networking terminal does not store the interrupted video networking service, the video networking terminal can ignore the service restoring instruction.

And step 604, the slave node continues to provide the video networking service for the video networking terminal accessed into the autonomous cloud based on the management of the new master node.

In the embodiment of the invention, after the new master node is determined, the new master node can take over the original master node with the fault to manage the slave nodes in the autonomous cloud, so that the normal operation of the autonomous cloud is ensured. Therefore, the slave node can continue to provide the video networking service for the video networking terminal accessed into the autonomous cloud based on the management of the new master node, so that the autonomous cloud can still keep normal operation to a certain degree after the master node fails, and the survivability of the video networking autonomous cloud is improved.

In a specific implementation, after the master node fails, the slave node can still retain the video networking service data generated by the video networking terminal in communication with the slave node for a period of time. Therefore, after the autonomous cloud generates a new main node to take over the failed main node, if the video networking terminal is connected to the slave node again, the slave node can continue to provide video networking services for the video networking terminal based on the reserved video networking service data, and the influence of the failure of the autonomous cloud on the video networking terminal is reduced.

As a specific example of the present invention, fig. 7 is a schematic structural diagram of an autonomous cloud according to the present invention. It includes a master node, slave node 1, slave node 2, and slave node 3. The master node cannot communicate with the slave node 1, the slave node 2, and the slave node 3 due to its own abnormality. At this time, the slave node 1, the slave node 2, and the slave node 3 may detect that the master node has failed, and thereafter, the slave node 1 may transmit election signaling to the slave node 2 and the slave node 3, the slave node 2 may transmit election signaling to the slave node 1 and the slave node 3, and the slave node 3 may transmit election signaling to the slave node 1 and the slave node 2. So that it can receive election signalling sent from node 2 as well as from node 3 for slave node 1. Thereafter, the slave node 1 may determine that the target node suitable as the new master node is itself based on the election signaling transmitted by itself and the election signaling transmitted from the node 2 and the node 3. The slave node 2 and the slave node 3 can determine that the target node suitable as the new master node is the other slave node according to the election signaling sent by the slave node 2 and the election signaling sent by the other slave nodes, and then the slave nodes can stop participating in the election. The slave node 1 may initiate a network management function to manage the slave node 2 and the slave node 3.

In one embodiment of the invention, in the case that the slave node cannot communicate with the master node, the autonomous cloud may include a network island including at least one slave node. When only one slave node exists in the network island, the slave node cannot communicate with the master node in the autonomous cloud or communicate with other slave nodes in the autonomous cloud, and is in a completely isolated state. In the case that at least two slave nodes exist in the network island, communication connection can be carried out between the slave nodes in the network island, but the slave nodes in the network island cannot communicate with a master node or a slave node outside the network island.

At this time, the slave node in the network island may also consider that the master node has a fault due to an abnormality in the communication connection between the master node and the slave node. In order to ensure that the slave nodes in the network island can normally operate, the node priority information can be sent, a new master node is selected from the network island, and the slave nodes in the network island are managed.

Specifically, the method may comprise:

s81, the slave node in the network island sends node priority information to other slave nodes except the slave node in the network island, and receives the node priority information sent by other slave nodes in the network island;

in the embodiment of the invention, under the condition that the slave node in the network island cannot normally communicate with the master node, in order to maintain the normal operation of the slave node in the network island, the slave node in the network island can determine the island master node in the network island in a mode of master node election, so that the normal operation of the slave node in the network island is maintained to a certain extent through the island master node, and the survivability of the autonomous cloud is improved.

Therefore, the slave node in the network island sends node priority information to other slave nodes except the slave node in the network island, receives the node priority information sent by other slave nodes in the network island, and selects a new master node in the network island based on the node priority.

And S82, selecting a new main node from the slave nodes in the network island by the slave nodes in the network island based on the node priority information sent by other slave nodes in the network island and the node priority information of the slave nodes.

In the embodiment of the invention, the slave nodes in the network island select new master nodes from the slave nodes in the network island based on the node priority information sent by other slave nodes in the network island and the node priority information of the slave nodes, so as to manage the slave nodes in the network island.

Furthermore, if only one slave node exists in the network island, the slave node can be set to be in a single-point operation mode. In the single-point operation mode, the slave node can manage itself and maintain normal operation of itself to a certain extent.

As an example of the present invention, fig. 8 is a schematic structural diagram of an autonomous cloud of the present invention, which includes a master node, a slave node 1, a slave node 2, and a slave node 3. The slave node 2 and the slave node 3 cannot communicate with the master node and the slave node 1 due to network abnormality, and the master node can continue to maintain communication with the slave node 1. The slave node 2 and the slave node 3 may communicate with each other such that the slave node 2 and the slave node 3 are in the same network island. At this time, the slave node 2 and the slave node 3 may detect that the master node fails and transmit election signaling, at this time, the slave node 3 may receive the election signaling transmitted from the slave node 2, and the master node and the slave node 1 outside the network island may not receive the election signaling transmitted from the slave node 2 or the slave node 3. Thereafter, the slave node 2 may determine a target node suitable as a new master node based on the election signaling sent by itself and the election signaling sent from the node 3. Thereafter, the slave node 2 may be determined to be a master node of the island, and the slave node 3 in the network island is managed.

In one embodiment of the invention, the method further comprises:

s91, if the new master node receives the survival notification signaling sent by other master nodes in the autonomous cloud; the new main node determines whether the node priority of other main nodes is greater than the node priority of the new main node according to the node priority information recorded by the survival communication signaling;

in the embodiment of the invention, in the process of managing the autonomous cloud, the new main node can recover the normal condition of the failed main node. At this time, the new master node may send a survival notification signaling to all nodes in the autonomous cloud by using a preset period to notify that the node is in a normal operation state. Therefore, the master node which returns to normal can receive the survival notification signaling sent by the new master node. At this time, the recovering normal master node can know that other master nodes exist in the autonomous cloud. The main node which is recovered to be normal can keep a management dormant state according to actual needs, does not take over the autonomous cloud, and becomes the main node for managing the autonomous cloud again in a mode of sending node priority information after a new main node fails, so that the management of the autonomous cloud is recovered. The normal recovery main node can also directly send the survival notification signaling without waiting for the new main node to go wrong, so that the new main node can receive the survival notification signaling sent by other main nodes in the autonomous cloud and know that other active main nodes exist in the autonomous cloud besides the main node.

In the embodiment of the present invention, a situation may also occur in which a slave node in a network island may communicate with a master node, so that the network island is eliminated. At this time, the new master node originally selected from the network island may receive the survival notification signaling sent by the master node managing the autonomous cloud, and the master node managing the autonomous cloud may also receive the survival notification signaling sent by the new master node originally selected from the network island. Therefore, the new main node originally selected from the network island and the main node for managing the autonomous cloud can know that other active main nodes exist in the autonomous cloud.

Under the condition that the failed main node is recovered to be normal or the network island is eliminated, if the new main node receives survival notification signaling sent by other main nodes in the autonomous cloud, the new main node can determine whether the new main node needs to continuously manage the autonomous cloud.

Therefore, the new master node can analyze the survival communication signaling to obtain node priority information recorded in the survival communication signaling, and then the new master node can determine whether the node priority of other master nodes is higher than the node priority of the new master node according to the node priority information so as to determine whether the new master node needs to continuously manage the autonomous cloud.

S82, if the node priority of other main nodes is higher than the node priority of the main node, the new main node sets itself as a slave node;

in the embodiment of the invention, if the new master node determines that the node priority of other master nodes is higher than the node priority of the new master node, the other master nodes can be considered to have higher priority, and the new master node does not need to continuously manage the autonomous cloud, the new master node can set the new master node as a slave node, enters a management sleep state, does not process the autonomous cloud management related service required to be processed by the master node any more, continues to operate as the slave node in the autonomous cloud, and continuously manages the autonomous cloud by the master nodes with higher priority.

And S83, if the node priority of other main nodes is not greater than the node priority of the main node, the new main node keeps itself as the main node.

In the embodiment of the present invention, if the node priority of another master node is not greater than the node priority of the master node, it may be considered that the priority of the other master node is lower, and the master node should continue to manage the autonomous cloud, so that the new master node may continue to maintain itself as the master node.

According to the anti-destruction method based on the video networking autonomous cloud network architecture, the slave node determines whether the master node fails or not so as to determine whether the autonomous cloud can maintain normal operation or not. If the slave node determines that the master node fails, the slave node sends node priority information to other slave nodes in the autonomous cloud, and receives the node priority information sent by the other slave nodes to the slave node, so that the slave node which can take over the failed master node is selected from the slave nodes of the autonomous cloud under the condition that the autonomous cloud cannot normally operate. The slave nodes select the slave node with the highest node priority as a new master node to take over the failed master node to manage the slave nodes in the autonomous cloud based on node priority information sent by other slave nodes and the node priority information of the slave nodes; the new master node manages the slave nodes in the autonomous cloud and controls the slave nodes in the autonomous cloud to continue providing the video networking service for the video networking terminal accessed into the autonomous cloud, so that the autonomous cloud can still keep normal operation to a certain degree after the master node fails, and the survivability of the video networking autonomous cloud is improved.

As a specific example of the present invention, the autonomous cloud may operate as follows:

switching flow:

in a normal state, the active master node always sends a survival notification signaling to all slave nodes and standby nodes in the autonomous cloud, when an exception occurs (the active master node is destroyed or the network is interrupted), the slave nodes and the standby nodes in the management sleep state cannot receive the survival notification signaling sent by the active master node, and after NMS _ VOTE _ TIME (preset election waiting TIME) seconds, the slave nodes and the standby nodes enter an election state and start to send election signaling.

And (3) election process:

all nodes (including slave nodes and standby nodes) participating in election send election signaling to all other nodes (all nodes in a multi-autonomous-networking list t _ nmsmultiinfo pre-stored in a database in the node), and each corresponding node receives election signaling sent by other nodes. After receiving the election signaling, comparing the node priority of the node with the node priority of the opposite end node, if the node priority of the node is higher than the node priority of the opposite end node, ignoring the election signaling, and if the node priority is lower than the node priority of the opposite end node, the node enters a management dormant state and does not participate in election until the next election is started.

In the process of comparing the node priorities, the node can compare NMS _ roll (preset node priority rule) firstly, wherein 1 (master node) has the highest priority, 2 (backup node) has the second priority, and 3 (slave node) is the lowest priority, when the priorities are the same (3 at the same time), the ip addresses of the two nodes are compared, and the ip address comparison mode is that a decimal character string is converted into an unsigned 4-byte integer (small end), and the priority of the node with the larger number is higher than that of the node with the smaller number.

After NMS _ RESTRAIN _ TIME (presetting election duration) seconds, if no election signaling with higher priority than the node of the node appears, the node is successfully elected and enters an active stage.

After the election is successful, a script for starting the floating ip is called (the script is used for setting an autonomous cloud external interface), a PIPE file is updated (the script is used for setting the state of a node to be an active state or a management dormant state), other nodes are informed, the node is in the active state, three signaling for recovering autonomous users, equipment and autonomous information are sent to the autonomous cloud, the autonomous cloud is restarted (the active and standby activities are not executed), then after 20 seconds, whether certain specific video network terminals are on line or not is checked (the specific video network terminals are read from configuration files of a storage gateway and a v2v proxy), and when and only when the video network terminals are in the non-network-accessing state, migration operation is executed, and the video network terminals are automatically migrated to a designated sub-control server.

Network island isolation process:

when a network island occurs, if the number of nodes in the network island is greater than 1, the aforementioned switching process can be adopted to select island master nodes in the network island.

When the number of the servers in the network island is 1, the cluster database shared by the multiple nodes reports errors and cannot be used, a single-point working mode needs to be set by network management personnel or the nodes, and then the nodes can continue to work.

Network island merging process:

after the network is recovered, two or more network islands are merged, nodes with the number equal to that of the islands are in an active state, when a server in the active state receives a survival notification signaling, node priority comparison is carried out, the server with a high priority continues to be in the active state, other servers return to a management dormant state, a PIPE file is updated, and a script for closing floating ip is called.

The active main node receives the suppression response packets of other members merged into the network island, all newly added members are recorded on the record, each time a new member is added, the active main node waits for a certain time, no new member is added, after the timeout, the active main node sends a database closing signaling to command the new member to delete a specific database file and close the mysql service, after the new member completes the operation, the active main node sends a completed response packet to the active server, after all the new members complete the operation, the active server sends a signaling for starting the database, after receiving the signaling, the new member starts the mysql service and sends a completed response packet, and therefore the database of the newly added members is merged into the same cluster database. And then the network island merging process is ended.
