In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.

For a better understanding of embodiments of the present invention, the following description of an autonomous network in a video networking is presented to those skilled in the art:

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

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

Starting from the autonomous cloud of the top layer, each autonomous cloud can be connected with one or more autonomous clouds of the next layer, the autonomous cloud of the lower layer is connected with the autonomous cloud of the next layer, and all the autonomous clouds are connected layer by layer in the mode until the autonomous cloud of the bottom layer is connected, so that an autonomous network is formed.

Obviously, the hierarchical structure is a tree structure, and the whole autonomous network is a tree consisting 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) connects autonomous clouds in a plurality of third layers (L3), an autonomous cloud in a third layer (L3) connects autonomous clouds in a plurality of second layers (L2), and an autonomous cloud in a second layer (L2) connects 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 visual network, the condition that the autonomous cloud is in fault when an autonomous server or a network management server in the autonomous cloud is in fault is avoided, so that the autonomous cloud can still keep the rest equipment to normally operate under the condition that part of equipment is in fault.

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

The slave node can be used for providing specific video networking service for the video networking terminal in the access autonomous cloud based on the management of the master node. Such as video-on-audio data, video-on-video data forwarding, control of video-on-terminals, registration, etc.

As a specific example of the present invention, the video networking terminal in the autonomous cloud may be a video networking conference set top box, a video telephone set top box, a surgery teaching set top box, a video networking streaming media gateway, a video networking media synthesizer, or the like through access from a node, which is not limited in this aspect of the present invention.

Optionally, the network architecture of the autonomous cloud may include at least one standby node, where the standby node is communicatively connected to the master node; the standby node is preconfigured to synchronously acquire the autonomous cloud management data and the network management data of the main node. Under the condition that the master node fails, the standby node can become a new master 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 master node, so that the switching between the master node and the standby node is realized, and the 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 in the master node and the network management servers can communicate with each other. The master control server in the master node can be used for managing and registering 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. The network management server in the master node is used for controlling the management services of the slave nodes in the autonomous cloud such as service opening, registration and the like through the master control server in the master node, and providing a calling interface for the outside of the autonomous cloud.

The slave node may include a master server, a network management server, and a slave server. The master control server in the slave node can be used for managing and registering the sub control servers in the slave node based on the management of the master node, and managing services such as network communication management. The network management server in the slave node can be used for controlling the service opening, registration and the like of the sub-control server in the slave node through the master control server in the slave node based on the management of the master node. The sub-control server in the slave node can be used for providing video networking services such as video networking audio and video forwarding, video networking set top box control, registration and the like for the video networking terminal.

Optionally, at least one standby node may be further included in the autonomous cloud. The backup 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, the self-control cloud management data of the master control server in the main node can be synchronously acquired, the network management server in the standby node can be communicated with the network management server in the main node, and the network management data of the network management server in the main node can be synchronously acquired. Thus, when the master node fails, the standby node can take over the master node to continuously manage the slave nodes in the autonomous cloud based on the autonomous cloud management data and the network management data synchronously acquired from the master node.

As an optional implementation manner in the present invention, the master server and the network management server of the master node may be integrated into a first integrated device. If a standby node needs to be set in the autonomous cloud, a main control server and a network management server of the integrated main node, and the main control server and the network management server of the standby node can be integrated into first integrated equipment. In addition, the master control server, the network management server and the sub-control server of the slave node can be integrated into a second integrated device. Therefore, under the condition that the autonomous cloud needs to be built, the first integrated equipment and the second integrated equipment can be built into the autonomous cloud, and the building of the autonomous cloud can be quickly completed.

Referring to fig. 5, a flowchart illustrating steps of an embodiment of a method for survivability based on an ad hoc network architecture of an internet of view of the present invention, the network architecture of the ad hoc cloud including 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 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 in the access autonomous cloud based on the management of the master node.

If the video networking terminal needs to be accessed into the autonomous cloud to acquire 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 master node in the autonomous cloud, then the master node in the autonomous cloud can allocate a slave node to 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 management of the master 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 can determine whether the master node fails or not so as to determine whether the autonomous cloud can still maintain normal operation or not.

In an alternative embodiment, the master node may actively employ a preset period to send survival notification signaling to the slave node. The survival notification signaling may be used to notify the slave node that the master node is still active, so that the slave node may determine that the master node has not failed if it receives the survival notification signaling. If the master node has not sent 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 operates normally, the master node can return response information corresponding to the survival inquiry signaling. If the master node fails, the master node cannot return response information corresponding to the survival inquiry signaling. The slave node may determine that the master node has failed if it has not received the response after sending out the survival inquiry signaling for a period of time.

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 node priority information sent by other slave nodes to the slave nodes;

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 extent under the condition that the master node fails, a new master node can be selected from the 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 the video networking service for the video networking terminal accessed into the autonomous cloud.

In the embodiment of the invention, the nodes in the autonomous cloud can have preset node priorities. In the case of a failure of a master node, the autonomous cloud may be preferentially taken over by the slave nodes with higher node priorities, so that in the case of a failure of a master node, the slave nodes that can be the new master node are rapidly determined.

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

Thus, 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 nodes.

Step 503, the slave node selects a new master node for taking over the failed master node to manage the slave nodes in the 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 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 original faulty master node to manage the slave nodes in the autonomous cloud, so that after the master node fails, the slave nodes in the autonomous cloud can take over the autonomous cloud, and the maintenance of normal operation of the autonomous cloud is ensured.

Specifically, the slave node analyzes the node priority information transmitted by other slave nodes, and knows the node priorities of other slave nodes. And then, the slave node can compare the node priority of the slave node with the node priorities of other slave nodes to determine the 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 replace the original fault master node to manage the slave nodes in the autonomous cloud.

And 504, the new master node manages slave nodes in the autonomous cloud, and controls the slave nodes in the autonomous cloud to continuously provide the video networking service to the video networking terminal in 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 fault master node, manage the slave nodes in the autonomous cloud, control the slave nodes in the autonomous cloud to continuously provide the video networking service for the video networking terminal in the autonomous cloud, and ensure the normal operation of the autonomous cloud. The slave nodes in the autonomous cloud can continuously provide the video networking service for the video networking terminal in the access 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 destructiveness of the video networking autonomous cloud is improved.

According to the method for resisting the destruction 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 nodes, 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 node selects a new master node based on node priority information sent by other slave nodes and node priority information of the slave node, and the new master node is used for taking over the failed master node to manage the slave nodes in the autonomous cloud; the new master node manages the slave nodes in the autonomous cloud and controls the slave nodes in the autonomous cloud to continuously provide the video networking service for the video networking terminal in the access autonomous cloud, so that the autonomous cloud can still keep normal operation to a certain extent after the master node fails, and the destructiveness of the video networking autonomous cloud is improved.

Referring to fig. 6, a flowchart illustrating steps of an embodiment of a method for survivability based on an ad hoc network architecture of an internet of view of the present invention, the network architecture of the ad hoc cloud including 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 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 in the access autonomous cloud based on the management of the master node.

The method comprises the following steps:

step 601, determining whether a master node fails by a slave node;

In 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 by other slave nodes to the slave nodes.

Thus, if the slave node determines that the master node fails, the slave node can send the 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 nodes.

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

S11, the slave node sends election signaling recording node priority information of the slave node to other slave nodes in the autonomous cloud, and receives election signaling recording node priority information of other slave nodes sent by other slave nodes; the election signaling is used for notifying the node which receives the election signaling, and the node which sends the election signaling participates in the election of the master node; 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 can have preset node priorities. In the case of a failure of a master node, the autonomous cloud may be preferentially taken over by the slave nodes with higher node priorities, so that in the case of a failure of a master node, the slave nodes that can be the new master node are rapidly determined.

Therefore, all the slave nodes which wish to participate in election in the autonomous cloud can send election signaling recording the priority information of the slave nodes 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 election of the master node.

The slave node can send the election signaling recorded with the node priority information of the slave node to other slave nodes in the autonomous cloud, and can also receive the election signaling sent by other slave nodes needing to participate in the election of the master node, 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 constructing the autonomous cloud, a network address may be configured for a node based on a node priority of the node. For example, nodes with higher node priorities may be configured to have smaller values of network addresses, such that the network addresses of the nodes may be 1.0.0.0, 1.0.0.1, 1.0.0.2, 1.0.0.3 … …, as the node priorities are from high to low. For example, if the network address of the slave node is 1.0.0.2 and the network address of the node corresponding to the election signaling received by the slave node is 1.0.0.1, the slave node may determine that the node with the network address 1.0.0.1 has a higher node priority than itself.

Specifically, a master node election in an autonomous cloud may not exist informing all slave nodes to enter an election state to participate in the process of election. After each slave node in the autonomous cloud determines the failure of the master node by itself, an election signaling can be directly sent to other slave nodes in the autonomous cloud to inform the slave nodes of the receiving end, and the slave nodes of the sending end participate in the election of the master node. The receiving end slave node may or may not have determined the master node failure and also sent election signaling. In the case that the receiving end slave node does not determine the failure of the master node and receives the election signaling. The receiving end slave node may determine whether the master node is faulty and also send election signaling after determining that the master node is faulty. Therefore, the autonomous cloud can automatically determine whether the master node is required to be elected or not by the slave nodes without additionally informing all the slave nodes to enter an elected state to participate in the elected, and directly enter the elected state to send an elected signaling.

In one embodiment of the present invention, the network architecture of the autonomous cloud further includes at least one standby node, the standby node being communicatively connected to the master node; the standby node is preconfigured to synchronously acquire self-control cloud management data and network management data of the main node;

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

The method further comprises the steps of:

S21, if the slave node determines that the master node fails, 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 invention, under the condition that the standby node exists in the autonomous cloud, the slave node determines that the main node fails, and the slave node can also send node priority information to the standby 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 may also receive node priority information sent by the slave node to the slave node.

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

s31, the slave node selects a new master node to be used for taking over the failed master node to manage the slave nodes in the autonomous cloud 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 invention, under the condition that the slave node receives the node priority information sent by the standby node, the slave node can 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 in the process of selecting the new master node. Therefore, under the condition that the master node fails, the slave node in the autonomous cloud can be managed by the slave node by taking over the failed master node in a mode of sending the node priority information.

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

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

S41, the standby node determines whether the main node fails;

in the embodiment of the invention, the standby node can determine whether the main node fails or not so as to determine whether the autonomous cloud can still maintain normal operation or not.

In a specific implementation, the standby node may receive the survival notification signaling of the primary node in 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 may also actively send a survival inquiry signaling using a preset period to inquire whether the primary node is still operating normally, so as to determine whether the primary node has a failure.

S42, if the standby node determines that the main node fails, the standby node sends node priority information to the slave node in the autonomous cloud and receives the node priority information sent from the slave node to the standby node;

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

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

In the embodiment of the invention, after the standby node obtains the node priority information sent by other slave nodes, a new master node can be selected 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 so as to replace the master node with the original fault to manage the slave nodes in the autonomous cloud.

In a specific implementation, the standby node may be preset with a node priority higher than the slave node and lower than the master node. Therefore, under the condition that the standby node participates in the election of the master node, the standby node can become a new master node in preference to the slave node, so that the standby node with the backup of the 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 based on node priority information sent by other slave nodes and node priority information of the slave node, and the slave node is used for taking over the master node of the original fault to manage the slave nodes in the autonomous cloud;

in the embodiment of the invention, after the slave node obtains the node priority information sent by other slave nodes, the node with the highest node priority can be selected 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, so as to replace the master node with the original fault to manage the slave nodes in the autonomous cloud.

Specifically, the slave node knows the node priorities of other slave nodes based on node priority information transmitted by other slave nodes. And then, the slave node can compare the node priority of the slave node with the node priorities of other slave nodes, determine the target master node with the highest node priority, and take the target master node as a new master node so as to take over the original fault master node to manage the slave nodes in the autonomous cloud.

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

S51, the slave node determines whether the own node priority is greater than the node priority 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 invention, the slave node can determine whether the slave node can become a new master node or not based on the node priority information sent by the slave node and the node priority information sent by other slave nodes recorded in the node priority information. Thus, the slave node can determine whether its own node priority is greater than the node priorities of other slave nodes to determine whether itself can become a new master node.

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

In the embodiment of the invention, if the node priority of the slave node is greater than the node priorities of other slave nodes, the slave node can determine that the slave node is the slave node participating in the election of the master node and the node priority is the highest at the moment, and in this case, the slave node can determine that the slave node is a new master node and send a master node notification signaling to other slave nodes in the autonomous cloud.

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

Thus, after receiving the master notification signaling, the other slave nodes can take the master node sending the master notification signaling as a new master node, and wait to receive 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 the other slave nodes to send the master node notification signaling.

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

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

S61, the new master node adopts preset network management data to start the network management function of the new master node;

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 take over the autonomous cloud in other modes. In this case, the new master node may start its own network management function using the preset gateway data.

In a specific implementation, the nodes in the autonomous cloud may store network management data in advance, where the network management data may include necessary data required by the nodes to manage other slave nodes in the autonomous cloud. The new master node can use the network management data to start the network management function of the new master node 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 the slave nodes in the autonomous cloud to recover the original working state;

In the embodiment of the invention, after the network management function is started, the new master node needs to restore the working state of other slave nodes in the autonomous cloud so as to restore the normal operation of the autonomous cloud. Therefore, the new master node can send an autonomous recovery signaling to other slave nodes in the autonomous cloud, wherein 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 accessing the nodes in the autonomous cloud, recover normal operation of devices in the autonomous cloud, recover configuration information of the nodes in the autonomous cloud, and the like, which is not limited in the present invention. Therefore, after receiving the autonomous reply signaling, other slave nodes in the autonomous cloud can continue to operate according to the working state before the original master node fails.

And S63, the new master node takes over the original master node to manage the slave nodes in the autonomous cloud so as to control the slave nodes to continuously provide the video networking service for the video networking terminal in the autonomous cloud.

In the embodiment of the invention, after the new master node determines 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 node to interact with other video networking equipment to realize the management of the slave node as the master node so as to control the slave node to continuously provide the video networking service to the video networking terminal in the autonomous cloud.

In one 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 adopts the autonomous cloud management data and the network management data to manage the slave nodes in the autonomous cloud.

In the embodiment of the invention, if the standby node is the target node serving as the new master node, the standby node can synchronously acquire the autonomous cloud management data of the master node in the operation process of the master node, so that the standby node does not need to additionally acquire the autonomous cloud management data, 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 accessed into the autonomous cloud.

The other view networking devices may be a view networking terminal accessing the autonomous cloud, a view networking device of other autonomous clouds, a view networking device 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 networking terminal is accessed to the autonomous cloud, the new master node sends a service restoration instruction to the video networking terminal; the service restoration instruction is used for indicating the video network terminal to restore the interrupted video network service.

In the embodiment of the invention, after the failure of the main node, the self-control cloud may disconnect the video networking terminal from the nodes in the self-control cloud, so that the video networking service is interrupted. The nodes in the autonomous cloud can continue to reserve data generated by the interaction of the video networking service between the slave nodes and the video networking terminal. Such as data generated by video networking services such as video telephony, live distribution, live viewing, video conferencing, etc. And then, taking over the autonomous cloud at the new main node, and re-accessing the autonomous cloud by the video networking terminal after the autonomous cloud is recovered to be normal. At this time, in order to enable the terminal to restore the originally ongoing video networking service, the new master node may send a service restoration instruction to the video networking terminal, so as to prompt the video networking terminal to restore the interrupted video networking service. After receiving the service restoration instruction, if the video networking terminal has an interrupted video networking service, the video networking terminal can attempt to restore the original communication with the autonomous cloud, so that the interrupted video networking service is restored. If the video networking service is a video conference service, the conference server of the master node assists in recovering the video conference service. If the video networking terminal does not have the interrupted video networking service, the video networking terminal can ignore the service restoration instruction.

In step 604, the slave node continues to provide the service of the video networking to the video networking terminal in 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 fault master node, manage the slave nodes in the autonomous cloud and ensure the normal operation of the autonomous cloud. Therefore, the slave node can continuously provide the video networking service for the video networking terminal in the access 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 destructiveness of the video networking autonomous cloud is improved.

In a specific implementation, after the slave node fails in the master node, the video networking service data generated by the communication between the video networking terminal and the slave node can still be reserved for a period of time. Therefore, after the autonomous cloud generates a new master node to take over the failed master node, if the slave node is accessed again by the video networking terminal, the slave node can continuously provide video networking service for the video networking terminal based on reserved video networking service data, so that 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 of the present invention. Which includes a master node, a slave node 1, a slave node 2, and a slave node 3. Among them, the master node cannot communicate with the slave node 1, the slave node 2, and the slave node 3 due to its own occurrence of an 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 signaling sent from node 2 as well as from node 3 for node 1. Thereafter, the slave node 1 can 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 by the slave node 2 and the slave 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 nodes according to the election signaling sent by themselves and the election signaling sent by the other slave nodes, and the slave nodes can stop participating in the election. The slave node 1 can activate a network management function to manage the slave node 2 and the slave node 3.

In one embodiment of the present invention, in the event that a slave node cannot communicate with a master node, the autonomous cloud may include a network island including at least one slave node therein. In the case that only one slave node exists in the network island, the slave node cannot communicate with a master node in the autonomous cloud and cannot communicate with other slave nodes in the autonomous cloud, and the slave node is in a completely isolated state. In case there are at least two slave nodes in the network island, communication connections may be made between the slave nodes in the network island, but the slave nodes in the network island cannot communicate with the master nodes or the slave nodes outside the network island.

At this time, since the communication connection between the master node and the slave node is abnormal, the slave node in the network island may also consider that the master node has a failure. In order to ensure that the slave nodes in the network island can normally operate, sending node priority information can be adopted, a new master node is selected from the network island, and the slave nodes in the network island are managed.

Specifically, the method may include:

S81, the slave nodes in the network island send node priority information to other slave nodes except the slave nodes in the network island, and receive 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 nodes in the network island cannot normally communicate with the master node, in order to maintain the normal operation of the slave nodes in the network island, the slave nodes in the network island can determine the island master node in the network island through the master node election mode so as to maintain the normal operation of the slave nodes in the network island to a certain extent through the island master node, thereby improving the anti-destruction performance of the autonomous cloud.

Therefore, the slave nodes in the network island send node priority information to other slave nodes except the slave nodes in the network island, and receive the node priority information sent by the other slave nodes in the network island, so that a new master node in the network island is selected based on the node priority.

S82, the slave nodes in the network island select new master nodes from the slave nodes in the network island based on node priority information sent by other slave nodes in the network island and node priority information of the slave nodes.

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

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

As an example of the present invention, fig. 8 is a schematic structural diagram of an autonomous cloud of the present invention, including a master node, a slave node 1, a slave node 2, and a slave node 3. Wherein 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. Slave node 2 and slave node 3 may communicate with each other such that slave node 2 and 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 send the election signaling, at this time, the slave node 3 may receive the election signaling sent by the slave node 2, and the master node and the slave node 1 outside the network island may not receive the election signaling sent by the slave node 2 or the slave node 3. Thereafter, the slave node 2 can determine a target node suitable as a new master node based on the election signaling transmitted by itself and the election signaling transmitted by the slave node 3. Thereafter, the slave node 2 may be determined to be an island master node and the slave node 3 in the network island may be managed.

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

S91, if the new master node receives survival notification signaling sent by other master nodes in the autonomous cloud; the new master node determines whether the node priority of other master nodes is greater than the node priority of the new master node according to the node priority information recorded by the survival communication signaling;

In the embodiment of the invention, the new master node can recover the normal situation of the failed master node in the process of managing the autonomous cloud. At this time, since the new master node may send a survival notification signaling to all nodes in the autonomous cloud by using a preset period, so as to notify that the node is in a normal running state. Therefore, the host node that resumes normal can receive the survival notification signaling sent by the new host node. At this time, the host node that resumes the normal can learn that other host nodes exist in the autonomous cloud. The normal recovery master node can keep management dormant state according to actual needs, does not take over the autonomous cloud, and after waiting for a new master node to fail, becomes the master node for managing the autonomous cloud again by sending node priority information, so as to recover management of the autonomous cloud. The host node which is recovered to be normal can also not need to wait for the new host node to fail, so that the survival notification signaling is directly sent, and the new host node can receive the survival notification signaling sent by other host nodes in the autonomous cloud, and know that other active host nodes exist in the autonomous cloud besides the host node.

In the embodiment of the invention, the situation that the slave node in the network island can communicate with the master node so that the network island is eliminated can also occur. 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 master node originally selected from the network island and the master node managing the autonomous cloud can know that other active master nodes exist in the autonomous cloud.

Under the condition that the main node with the fault 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 still 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 greater than the node priority of the new master node according to the node priority information so as to determine whether the new master node still needs to continuously manage the autonomous cloud.

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

In the embodiment of the invention, if the new master node determines that the node priority of the other master nodes is greater than the node priority of the new master node, the priority of the other master nodes can be considered to be higher, the new master node does not need to manage the autonomous cloud, the new master node can set the new master node as the slave node to enter the management dormant state, the related service of the autonomous cloud management which needs to be processed by the master node is not processed any more, the new master node is used as the slave node to continue to operate in the autonomous cloud, and the master node with the higher priority continues to manage the autonomous cloud.

And S83, if the node priority of the 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 invention, if the node priority of the other master nodes is not greater than the node priority of the new master node, the priority of the other master nodes can be considered to be lower, and the new master node can keep on managing the autonomous cloud.

According to the method for resisting the destruction 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 nodes, 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 node selects the slave node with the highest node priority as a new master node based on node priority information sent by other slave nodes and own node priority information to be used for taking over the slave node in the fault master node management autonomous cloud; the new master node manages the slave nodes in the autonomous cloud and controls the slave nodes in the autonomous cloud to continuously provide the video networking service for the video networking terminal in the access autonomous cloud, so that the autonomous cloud can still keep normal operation to a certain extent after the master node fails, and the destructiveness of the video networking autonomous cloud is improved.

As a specific example of the present invention, an autotrophic cloud may operate in the following manner:

and (3) switching the flow:

Under normal state, the active master node always sends survival notification signaling to all slave nodes and standby nodes in the autonomous cloud, when abnormality occurs (the active master node is destroyed or the network is interrupted), the slave nodes and standby nodes in the management dormant 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 standby nodes enter an election state and start sending election signaling.

And (3) selecting a process:

All nodes participating in election (including slave nodes and standby nodes) send election signaling to all other nodes (all nodes in the multi-autonomous networking list t_ nmsmultiinfob stored in advance in the database in the node), and each corresponding node receives the election signaling sent by the other nodes. After receiving the election signaling, comparing the node priority of the node with the node priority of the opposite terminal node, if the node priority of the node is larger than the node priority of the opposite terminal node, ignoring the election signaling, and if the node priority is lower than the node priority of the opposite terminal node, entering a management dormant state, and not participating in election until the next election starts.

In the node priority comparison process, the node may compare nms_row (preset node priority rule) first, where 1 (master node) has the highest priority, 2 (slave node) has the lowest priority, and 3 (slave node) has the lowest priority, and when the priorities are the same (3 at the same time), the ip addresses of the two nodes are compared, where the ip address comparison mode is to convert the decimal character string into an integer (small end) of 4 bytes without symbols, and the node with a larger number has a higher priority than the size of the two digits.

After nms_ RESTRAIN _time (preset election duration) seconds, if no election signaling with higher priority than the node of the node occurs, the node is successfully elected, and the active phase is entered.

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

Network island isolation flow:

When the network island appears, if the number of nodes in the network island is greater than 1, the above-mentioned switching flow can be adopted to elect island main nodes in the network island.

When the number of servers in the network island is 1, the cluster database shared by multiple nodes is wrongly reported and cannot be used, the network manager or the node needs to be set into a single-point working mode by itself, and then the node can continue to work.

Network island merging process:

When the network is restored, two or more network islands are fused, nodes with the same quantity as the islands are in an active state, after the servers in the active state receive the survival notification signaling, node priority comparison is carried out, the servers with high priority continue to keep the active state, the rest servers return to a management dormant state, PIPE files are updated, and a script for closing the floating ip is called.

The active master node receives the inhibition response packets of some other members in the incorporated network island, all newly added members are recorded in the record, a certain time is waited for when new members are added each time, no new members are added, after overtime, the active master node sends a database closing signaling to instruct the new members to delete a specific database file and close mysql service, when the new members complete the operation, the active server sends a completed response packet to the active server, after all new members complete the operation, the active server sends a signaling for starting the database, after the new members receive the signaling, mysql service is started, and the completed response packet is sent, so that the databases of the newly added members are combined into the same cluster database. The network island incorporation process then ends.

the partial techniques applied by the video networking are as follows:

network technology (Network Technology)

The network technology innovation of the internet of vision improves on the traditional Ethernet (Ethernet) to face the potentially huge video traffic on the network. Unlike pure network packet switching (PACKET SWITCHING) or network circuit switching (Circuit Switching), the technology of video networking employs PACKET SWITCHING to meet Streaming requirements. The video networking technology has the flexibility, simplicity and low price of packet switching, and simultaneously has the quality and the safety guarantee of circuit switching, thereby realizing the seamless connection of the whole network switching type virtual circuit and the data format.

Exchange technology (SWITCHING TECHNOLOGY)

The video network adopts the two advantages of the asynchronization and the packet switching of the Ethernet, eliminates the Ethernet defect on the premise of full compatibility, has full-network end-to-end seamless connection, and is directly connected with the user terminal to directly bear the IP data packet. The user data does not need any format conversion in the whole network. The video networking is a higher-level form of Ethernet, is a real-time exchange platform, can realize real-time transmission of full-network large-scale high-definition video which cannot be realized by the current Internet, and pushes numerous network video applications to high definition and unification.

Server technology (Server Technology)

The server technology on the video networking and unified video platform is different from the server in the traditional sense, the streaming media transmission is based on connection-oriented basis, the data processing capability is irrelevant to the flow and the communication time, and a single network layer can contain signaling and data transmission. For voice and video services, the complexity of video networking and unified video platform streaming media processing is much simpler than that of data processing, and the efficiency is greatly improved by more than hundred times than that of a traditional server.

Accumulator technology (Storage Technology)

The ultra-high-speed storage technology of the unified video platform adopts the most advanced real-time operating system for adapting to the ultra-large capacity and ultra-large flow media content, the program information in the server instruction is mapped to a specific hard disk space, the media content does not pass through the server any more, the media content is instantly and directly delivered to a user terminal, and the waiting time of the user is generally less than 0.2 seconds. The optimized sector distribution greatly reduces the mechanical motion of magnetic head seek of the hard disk, the resource consumption only accounts for 20% of the IP Internet of the same grade, but the concurrent flow which is 3 times greater than that of the traditional hard disk array is generated, and the comprehensive efficiency is improved by more than 10 times.
