Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to solve the technical problem, embodiments of the present invention provide an apparatus exception handling method and apparatus, and a cloud storage system. The method and the device can be applied to any node equipment in the cloud storage system.

First, a detailed description is given of a device exception handling method according to an embodiment of the present invention.

Fig. 1 is a first flowchart of an apparatus exception handling method according to an embodiment of the present invention, including:

s101: and judging whether the adjacent node equipment of the node equipment is abnormal or not, and if so, executing S102.

S102: and sending the information of the abnormal node equipment to other node equipment except the node equipment and the abnormal node equipment in the cloud storage system.

S103: and determining the processing strategy of the access data or the storage data of the abnormal node equipment through information interaction with other node equipment.

By applying the embodiment shown in fig. 1 of the present invention, if an abnormal node device exists in the cloud storage system, each node device without abnormality determines the processing policy of the data of the abnormal node device, and thus, in this scheme, even if the management device is abnormal, each node device without abnormality can still determine the processing policy, and if any device is abnormal, each node device without abnormality can determine the processing policy, thereby improving the stability of the video cloud storage system.

The embodiment shown in FIG. 1 is described in detail below:

s101: and judging whether the adjacent node equipment of the node equipment is abnormal or not.

As an embodiment, before S101, a connection relationship may be established with a neighboring node device of the node device; sending detection information to the adjacent node equipment according to a preset period; judging whether feedback information of the adjacent node equipment is received or not; if not, S101 is executed again.

For example, the node device may establish a heartbeat connection with the neighboring node device, and when detecting that the heartbeat of the neighboring node device is overtime, the node device may continue to determine whether the neighboring node device is abnormal. Specifically, the node device may communicate with the neighboring node device, determine whether information fed back by the neighboring node device is received, and if not, indicate that the neighboring node device is abnormal.

As an embodiment, shared information may be stored in the cloud storage system, and each node device in the system writes its own attribute information into the shared information. In this way, the shared information includes attribute information of each node device in the system, and each node device in the system can access or modify the shared information. The shared information may be stored in any one or more devices in the system, and is not limited in particular.

In this embodiment, the shared information may include a sequence number of each node device, and each node device may determine its own neighboring node device according to the sequence number. For a simple example, assuming that the system includes 10 node devices with sequence numbers 1-10, the node device with sequence number 3 may have a sequence number 2 or 4 as its neighboring node device.

In this embodiment, each node device may periodically update its own attribute information in the shared information, so that the node device may determine whether the update of the attribute information of the neighboring node device in the shared information by the neighboring node device is abnormal.

For example, if each node device in the system updates its own attribute information in the shared information every 10 minutes, the node device may monitor the shared information, determine whether its neighboring node device updates its attribute information in 10 minutes, and if not, indicate that the neighboring node device is abnormal.

If the judgment result of S101 is yes, S102 is executed.

As an implementation manner, after establishing a connection relationship with an adjacent node device, the node device may obtain information of the adjacent node device, and broadcast the information of the abnormal node device to other node devices in the system when determining that the adjacent node device is an abnormal node device.

Or, in the above-mentioned one embodiment, the cloud storage system stores shared information, the shared information includes attribute information of each node device, and each node device can access and modify the shared information, so that the node device can modify the attribute information of the abnormal node device in the shared information, and other node devices in the system can determine information of the abnormal node device according to the modified shared information.

Specifically, each node device may monitor whether the shared information is modified, and if the shared information is modified, determine information of the abnormal node device according to the modified shared information.

For example, each non-anomalous node device in the system may negotiate to determine a policy for processing data of the anomalous node device. The processing strategy can equally distribute and process the data of the abnormal node equipment for each non-abnormal node equipment; or, the data processed by each non-abnormal node device may also be determined according to the processing capability of each non-abnormal node device; or, one or more non-abnormal node devices may be designated to process the data of the abnormal node device according to the processing capability of each non-abnormal node device, and the specific policy is not limited.

As an embodiment, S103 may include: and selecting one or more distribution node devices through information interaction with the other node devices, wherein the distribution node devices are used for determining the processing strategy of the access data or the storage data of the abnormal node devices.

In this embodiment, the distributed node device is generated by electing each non-abnormal node device, and then the distributed node device determines the processing policy.

For the distribution node device, the distribution node device may determine, according to the shared information of the cloud storage system, a processing policy of access data or storage data of the abnormal node device; the shared information includes attribute information of each node device in the cloud storage system, and the processing strategy includes information of each node device participating in processing access data or storage data of the abnormal node device.

Specifically, the attribute information includes a processable data amount of the node device and/or priority information of the processed data; the distribution node device may determine a processing policy of the access data or the storage data of the abnormal node device according to the processable data amount and/or the priority information of the processing data.

The distribution node device may send the determined distribution policy to each node device participating in processing of the abnormal node device data.

For the node device participating in processing the abnormal node device data, the process of participating in processing the abnormal node device data is similar, and it is assumed that the node device is a node device participating in processing the abnormal node device data, and the description will be given by taking the node device as an example:

In particular, the node device in the cloud storage system may be a video access device or a video storage device. The video access equipment is in communication connection with the acquisition equipment, and the acquisition equipment accesses the acquired video data to the video access equipment. The video access equipment is in communication connection with the video storage equipment, and stores the access data into the video storage equipment.

And if the node equipment is video access equipment, the equipment to be processed is acquisition equipment. The video access equipment can send prompt information to the acquisition equipment connected with the abnormal video access equipment, so that the acquisition equipment sends the access data corresponding to the video access equipment according to the prompt information.

In one case, each video access device participating in processing the abnormal video access device data may send a prompt message to the acquisition device connected to the abnormal video access device, where each prompt message includes access data information corresponding to the video access device that sent the prompt message.

For example, assume that the acquisition device a is connected to the abnormal video access device B1, and assume that the video access devices participating in the data access of the processing device B1 are: b2, B3, B4; the prompt information sent by the B2 to the acquisition equipment A contains access data information corresponding to the B2, the prompt information sent by the B3 to the acquisition equipment A contains access data information corresponding to the B3, and the prompt information sent by the B4 to the acquisition equipment A contains access data information corresponding to the B4; in this way, the acquisition device a transmits access data to the devices B2, B3, and B4, respectively, based on the three pieces of prompt information.

In another case, a video access device may send a prompt message to a collection device connected to the abnormal video access device, where the prompt message includes access data information corresponding to each video access device participating in processing data of the abnormal video access device.

For example, assume that the acquisition device a is connected to the abnormal video access device B1, and assume that the video access devices participating in the data access of the processing device B1 are: b2, B3, B4; b2 sending prompt information to the acquisition equipment A, wherein the prompt information comprises access data information corresponding to B2, B3 and B4; in this way, the acquisition device a transmits access data to the devices B2, B3, and B4, respectively, based on the prompt information.

And if the node equipment is video storage equipment, the equipment to be processed is video access equipment. The video storage device can send prompt information to the video access device connected with the abnormal video storage device, so that the video access device sends the storage data corresponding to the video storage device according to the prompt information.

In one case, each video storage device participating in processing of abnormal video storage device data may send a prompt message to a video access device connected to the abnormal video storage device, where each prompt message includes stored data information corresponding to the video storage device that sent the prompt message.

For example, suppose that the video access device a is connected to the abnormal video storage device B1, and suppose that the video storage devices participating in the data access of the processing device B1 are: b2, B3, B4; the prompting information sent by the B2 to the video access equipment A comprises access data information corresponding to the B2, the prompting information sent by the B3 to the video access equipment A comprises access data information corresponding to the B3, and the prompting information sent by the B4 to the video access equipment A comprises access data information corresponding to the B4; in this way, the video access apparatus a transmits access data to the apparatuses B2, B3, and B4, respectively, based on the three pieces of hint information.

In another case, a video storage device may send a prompt message to a video storage device connected to the abnormal video storage device, where the prompt message includes stored data information corresponding to each video storage device participating in processing data of the abnormal video storage device.

For example, suppose that the video access device a is connected to the abnormal video storage device B1, and suppose that the video storage devices participating in the data access of the processing device B1 are: b2, B3, B4; b2 sending prompt information to the video access device A, wherein the prompt information contains access data information corresponding to B2, B3 and B4; in this way, the video access apparatus a transmits access data to the apparatuses B2, B3, and B4, respectively, based on the cue information.

Fig. 2 is a second flowchart of the device exception handling method according to the embodiment of the present invention, where the method includes:

s201: the attribute information of the node equipment is written into the shared information of the cloud storage system, and the attribute information of the node equipment in the shared information is updated regularly.

In this embodiment, shared information may be stored in the cloud storage system, and each node device in the system writes its own attribute information into the shared information, and periodically updates the written own attribute information. In this way, the shared information includes attribute information of each node device in the system, and each node device in the system can access or modify the shared information. The shared information may be stored in any one or more devices in the system, and is not limited in particular.

As an implementation manner, Zookeeper service may be run in each node device of the cloud storage system, and the Zookeeper service is a distributed application coordination service. The shared information may be information in a Zookeeper service. Each node device in the system establishes a Zookeeper child node belonging to itself, writes the attribute information of itself into the Zookeeper child node of itself, and periodically updates the Zookeeper child node of itself.

Each node device can access the Zookeeper child nodes of other node devices by using the Zookeeper service, and read the attribute information of other node devices.

S202: and determining the adjacent node equipment of the node equipment according to the serial numbers of the node equipment in the cloud storage system contained in the shared information.

The attribute information may include a serial number of the node device. For each node device, it may determine its own neighboring node device according to the sequence number. For a simple example, assuming that the system includes 10 node devices with sequence numbers 1-10, the node device with sequence number 3 may have a sequence number 2 or 4 as its neighboring node device.

S203: and establishing a connection relation with the adjacent node equipment of the node equipment.

S204: and sending detection information to the adjacent node equipment according to a preset period.

S205: and judging whether the feedback information of the adjacent node equipment is received or not, and if not, executing S206.

For example, the node device may establish a heartbeat connection with the neighboring node device, and if a Zookeeper service is operated in each node device in the system, the node device may send the detection information to the neighboring node device by using a heartbeat mechanism in the Zookeeper service, and receive the feedback information. If the node device does not receive the feedback information of the neighboring node device within the preset time length, it indicates that the heartbeat of the neighboring node device is over time, and in this case, S206 is continuously executed.

S206: and judging whether the updating of the attribute information of the adjacent node equipment in the shared information by the adjacent node equipment is abnormal or not, and if so, executing S207.

As described above, in this embodiment, each node device periodically updates its own attribute information in the shared information, so that the node device can determine whether the update of the attribute information of the neighboring node device in the shared information by the neighboring node device is abnormal.

For example, if each node device in the system updates its own Zookeeper child node every 10 minutes, the node device may monitor whether the Zookeeper child node of the neighboring node device updated by the neighboring node device is abnormal; and if the node equipment is abnormal, confirming the adjacent node equipment as abnormal node equipment.

S207: and modifying the attribute information of the abnormal node equipment in the shared information so that other node equipment except the node equipment and the abnormal node equipment in the cloud storage system determines the information of the abnormal node equipment according to the modified shared information.

After the node equipment judges that the adjacent node equipment is abnormal, the Zookeeper child node of the abnormal node equipment can be modified by using the Zookeeper service; in this way, other node devices may obtain information of the abnormal node device by using the Zookeeper service.

S208: and selecting one or more distribution node devices through information interaction with the other node devices.

Each non-abnormal node device in the system can use an election mechanism in the Zookeeper service to elect one or more distribution node devices.

S209: and judging whether the node equipment is the distribution node equipment or not, if so, executing S210, and if not, executing S211.

S210: and determining a processing strategy of the access data or the storage data of the abnormal node equipment according to the shared information, wherein the processing strategy comprises the information of each node equipment participating in processing the access data or the storage data of the abnormal node equipment.

For example, serial numbers may be allocated to each node device in advance, a circular linked list of the serial numbers may be established, and priority information of processing data may be determined according to the positions of the serial numbers of each node device in the circular linked list.

S211: and judging whether the node equipment participates in processing the access data or the storage data of the abnormal node equipment, if so, executing S212.

S212: and determining and processing the access data or the storage data corresponding to the node equipment according to the processing strategy.

And if the node equipment is video access equipment, determining and processing the access data corresponding to the video access equipment according to the processing strategy. And if the node equipment is the video storage equipment, determining and processing the storage data corresponding to the video storage equipment according to the processing strategy.

S213: and sending prompt information to the equipment to be processed connected with the abnormal node equipment so that the equipment to be processed sends the access data or the storage data corresponding to the node equipment according to the prompt information.

In the following, taking a node device as a video access device as an example, an optional implementation manner is provided:

a Cloud _ Access parent node may be created under the Zookeeper service, then each video Access device in the system creates its own child node under the parent node, where the child node includes attribute information of the video Access device, such as a name of the video Access device, video recording plan information, video recording plan Access capability, video storage server information of recorded and written data, an IP address of the video Access device, and the like, and is not limited specifically.

Suppose that the cloud storage system includes three video access devices, and the child nodes of the three video access devices are respectively: /Cloud _ Access/30000000002,/Cloud _ Access/10000000006 and/Cloud _ Access/40000000009. The child node ordering principle may be: 10000000006<30000000002< 40000000009. As an embodiment, a circular linked list may be established according to the sequence numbers of the child nodes, and the circular linked list may be as shown in FIG. 3.

Each node device can update its child node periodically. Each node device establishes heartbeat connection with the adjacent video access device in the chain table according to the circular chain table shown in fig. 3, communicates with the video access device with abnormal heartbeat after detecting that the adjacent video access device has abnormal heartbeat, and further judges whether the video access device with abnormal heartbeat is abnormal or not; or, the video access device monitoring the heartbeat abnormality updates whether the Zookeeper child node is abnormal.

If the video access equipment judges that the video access equipment with the abnormal heartbeat is abnormal, the video access equipment modifies the Zookeeper child node of the abnormal video access equipment so as to inform other video access equipment of the information of the abnormal video access equipment. In this case, a new circular linked list may be generated, where the new circular linked list does not include the serial number of the abnormal video access device.

As an embodiment, a callback function may be set under the parent node, and when the child node sends a change, each video access device may be notified through the callback function.

And each non-abnormal video access device determines the processing strategy of the access data of the abnormal video access device by using the Zookeeper. Or, each non-abnormal video access device may elect one or more distribution node devices by using an election mechanism in the Zookeeper, and the distribution node devices determine a processing policy of access data of the abnormal video access device.

The processing strategy can equally distribute and process the data of the abnormal video access equipment for each non-abnormal video access equipment; or, the data processed by each non-abnormal video access device may also be determined according to the processing capability of each non-abnormal video access device; or, one or more non-abnormal video access devices may be designated to process the data of the abnormal video access device according to the processing capability of each non-abnormal video access device, and the specific policy is not limited.

For convenience of description, the "non-abnormal video access device participating in processing data of the abnormal video access device" will be referred to as a successor device. One or more take-over devices can send prompt information to the acquisition device connected with the abnormal video access device, so that the acquisition device accesses the acquired video data to the take-over device.

In the following, an optional implementation is provided by taking a node device as a video storage device as an example:

a Cloud _ Stroage parent node may be created under the Zookeeper service, then each video storage device in the system creates its own child node under the parent node, where the child node includes attribute information of the video storage device, such as a name, total storage capacity, storage free capacity, video access server information of video data, video front-end camera information of video data, and an IP address of the video storage device, and is not limited specifically.

Suppose that the cloud storage system includes three video storage devices, and the child nodes of the three video storage devices are respectively: /Cloud _ Stroage/20000000001,/Cloud _ Stroage/50000000010 and/Cloud _ Stroage/60000000005. The child node ordering principle may be: 20000000001<50000000010< 60000000005. As an embodiment, a circular linked list may be established according to the sequence numbers of the child nodes, and the circular linked list may be as shown in FIG. 4.

Each node device can update its child node periodically. Each node device establishes heartbeat connection with the adjacent video storage device in the chain table according to the circular chain table shown in fig. 4, communicates with the video storage device with abnormal heartbeat after detecting that the adjacent video storage device has abnormal heartbeat, and further judges whether the video storage device with abnormal heartbeat is abnormal or not; or, the video storage device monitoring the heartbeat abnormality updates whether the Zookeeper child node is abnormal or not.

If the video storage device judges that the video storage device with the abnormal heartbeat is abnormal, the video storage device modifies the Zookeeper child node of the abnormal video storage device to inform other video storage devices of the information of the abnormal video storage device. In this case, a new circular linked list may be generated, where the new circular linked list does not include the serial number of the abnormal video storage device.

As an embodiment, a callback function may be set under the parent node, and when the child node information sends a change, each video storage device may be notified through the callback function.
