2. Video networking packet definition

2.1 Access network packet definition

The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.

As shown in the following table, the data packet of the access network mainly includes the following parts:

DA

SA

Reserved

Payload

CRC

wherein:

the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;

the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);

the reserved byte consists of 2 bytes;

the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;

the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.

2.2 metropolitan area network packet definition

The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.

In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.

As shown in the following table, the data packet of the metro network mainly includes the following parts:

DA

SA

Reserved

label (R)

Payload

CRC

Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.

Referring to fig. 5, a flowchart illustrating steps of a method for data processing based on a video network according to an embodiment of the present invention is shown, where the method may employ a central storage server, and the central storage server may be connected to a plurality of data centers, and specifically may include the following steps:

step 501, receiving a monitoring data acquisition request aiming at a first monitoring device sent by a video network terminal;

the first monitoring device may be a monitoring device that is to read monitoring data, for example, may acquire monitoring video data for a monitoring camera.

In the process of reading the monitoring data, the central storage server may receive a monitoring data acquisition request for the first monitoring device sent by the video network terminal, so as to further read the monitoring data according to the monitoring data acquisition request.

The central storage server can be connected with a plurality of data centers and a plurality of monitoring access servers, each monitoring access server can be connected with a plurality of monitoring devices, when monitoring video data are required to be read for checking, the video network terminal can acquire a monitoring list from the monitoring access servers, the monitoring list can comprise a plurality of monitoring device IDs, then the monitoring devices of the monitoring video data to be read can be determined from the monitoring devices according to the monitoring list, and then the video network terminal can send monitoring data acquisition requests to the central storage server aiming at the monitoring devices of the monitoring video data to be read so as to read the monitoring video data for checking.

Step 502, according to the monitoring data obtaining request, determining one or more first shard storage information of the requested first monitoring data, where the one or more first shard storage information is used to indicate one or more first data centers that sharely store the first monitoring data;

the first monitoring data may be monitoring data to be read, for example, monitoring video data of a monitoring camera may be read; the first monitoring data can be stored in one or more first data centers in a pre-slicing mode.

As an example, the first sharded storage information may be storage path information stored for shards of the first monitoring data, which may be used to indicate one or more first data centers that the shards store the first monitoring data.

After receiving the monitoring data obtaining request, determining one or more first shard storage information of the requested first monitoring data according to the monitoring data obtaining request, where the one or more first shard storage information may be used to indicate one or more first data centers in which the shards store the first monitoring data, and further, obtaining data from the one or more first data centers in which the shards store the first monitoring data according to the one or more first shard storage information.

For example, the first monitoring data may be stored in advance in a fragmented manner in one or more first data centers, and for the first monitoring data, one or more first fragmented storage information may be corresponded, which may be used to instruct the one or more first data centers that fragment-store the first monitoring data, and further, the first monitoring data may be further acquired by determining the one or more first fragmented storage information of the requested first monitoring data, that is, the storage path information for the first monitoring data.

In an example, the first sharded storage information may include storage data center IDs of one or more first data centers that sharely store the first monitoring data, and specific storage paths in the data centers, so that the stored monitoring data to be read may be acquired from the one or more first data centers.

Step 503, controlling the one or more first data centers to send the first monitoring data to the video network terminal according to the one or more first fragment storage information.

After the one or more pieces of first fragmentation storage information are obtained, one or more first data centers for fragmentally storing the first monitoring data to be read can be determined according to the one or more pieces of first fragmentation storage information of the requested first monitoring data, and then the one or more data centers can be controlled to send the first monitoring data to be read to the video networking terminal.

Specifically, the central storage server may receive a monitoring data acquisition request sent by the video networking terminal, and then may determine one or more data centers in which to-be-read monitoring data is stored in a fragmented manner according to the monitoring data acquisition request, and further, the central storage server may send information of the video networking terminal to the one or more data centers, so that the one or more data centers send the stored to-be-read monitoring data to the video networking terminal.

In an embodiment of the present invention, the first monitoring data may include first shard data stored in one or more first data centers, and step 503 may include the following sub-steps:

substep 11, determining first sliced data stored in the one or more first data centers according to the one or more first sliced storage information;

the first monitoring data may include first sharded data stored in one or more first data centers, and the first sharded data may be one or more sharded data for the first monitoring data.

After the one or more pieces of first fragmentation storage information are obtained, one or more first data centers where the fragments store the first monitoring data to be read can be determined according to the one or more pieces of first fragmentation storage information of the requested first monitoring data, and then the first fragmentation data stored in the one or more first data centers can be determined.

In an example, the first shard storage information may be storage path information of the first shard data for the first monitoring data, for example, a storage path of the shard data may be determined according to the shard storage information, and the shard storage information may include a storage data center ID for the shard data and a specific storage path in the data center.

In an embodiment of the present invention, the monitoring data obtaining request may include at least an identifier of the first monitoring device.

In an embodiment of the present invention, the monitoring data obtaining request may further include first time period information, and the method may further include the following steps:

determining one or more candidate fragment storage information according to the identifier of the first monitoring device; determining candidate fragment time period information corresponding to the candidate fragment storage information; and determining candidate fragmentation time period information matched with the first time period information as first fragmentation time period information, and determining one or more first fragmentation storage information from the one or more candidate fragmentation storage information according to the first fragmentation time period information.

As an example, the monitoring data obtaining request may include an identifier of the first monitoring device and first time period information, for example, a monitoring device ID of the monitoring video data to be read and time period information of the monitoring video data to be read may be included.

After receiving the monitoring data acquisition request, the identifier of the first monitoring device may be acquired from the monitoring data acquisition request, and then one or more candidate piece storage information may be determined according to the identifier of the first monitoring device, where the candidate piece storage information may be all piece storage information for the first monitoring device, and then candidate piece time period information corresponding to the candidate piece storage information may be determined, that is, each piece storage information may correspond to time period information for stored piece data.

And then, the candidate fragmentation time period information matched with the first time period information can be determined to be the first fragmentation time period information, and one or more first fragmentation storage information can be determined from one or more candidate fragmentation storage information according to the first fragmentation time period information, so as to further obtain the monitoring data according to the first fragmentation storage information.

In an example, the video network terminal may send time period information of the monitoring video data to be read and monitoring device information to the central storage server, and then the central storage server may obtain a monitoring video data storage list corresponding to the monitoring device according to the monitoring device information, where the monitoring video data storage list may include fragment storage information of all fragment data for the monitoring device.

In yet another example, the first fragment period information may be one or more fragment period information for the first period information, for example, since the to-be-read surveillance video data may include one or more fragment data, the period information of the to-be-read surveillance video data may correspond to the one or more fragment period information.

And a substep 12, controlling the one or more first data centers to send first fragmented data corresponding to the first fragmented storage information to the terminal of the internet of view.

After the first fragment data is obtained, one or more first data centers may be controlled to send the first fragment data corresponding to the first fragment storage information to the video networking terminal, for example, the first fragment data corresponding to the first fragment storage information may be sent to the video networking terminal through one or more data centers storing the first monitoring data to be read, that is, the monitoring data to be read corresponding to the monitoring data acquisition request may be sent to the video networking terminal.

After the monitoring requirement information is obtained, a data center list may be determined according to the monitoring requirement information, where the data center list may include one or more identifiers of the second data center, so as to further perform monitoring data storage through the second data center.

In practical application, the central storage server may obtain monitoring device information connected to the monitoring access server through all monitoring access servers in the video network, where the monitoring device information may include monitoring device IDs, monitoring camera channel information, and the like, and then a central storage server administrator may formulate a monitoring video recording plan, where the monitoring video recording plan may include time period information for storing monitoring video data, and when the monitoring video recording plan is executed, the central storage server may calculate an optimal data center list according to the monitoring video data information to be stored and the data center information, where the optimal data center list may include one or more data center IDs.

As an example, the second monitoring data may be monitoring data to be stored, for example, monitoring video data of a monitoring camera may be stored.

After the data center list is determined, one or more data centers of the monitoring data to be stored can be determined according to the monitoring demand information and the data center list, and then a second monitoring access server connected with second monitoring equipment can be controlled to store second monitoring data corresponding to the monitoring demand information to the one or more second data centers.

In an embodiment of the present invention, the method may further include the following steps:

As an example, the second sharded storage information may be storage path information stored for shards of the second monitoring data, which may be used to indicate one or more second data centers that the shards store the second monitoring data.

After the second monitoring data is stored in the one or more second data centers in a fragmented manner, second fragmentation storage information sent by the one or more second data centers may be received, and a corresponding relationship between an identifier of the second monitoring device and the second fragmentation storage information may be established, where the second fragmentation storage information may be used to indicate the one or more second data centers in which the second monitoring data is stored in a fragmented manner.

In a specific implementation, the second monitoring data may be fragmented by the second monitoring access server into one or more second fragmented data, and may be stored in one or more second data centers, that is, the second monitoring data may include the second fragmented data stored in the one or more second data centers, and each second fragmented data may have second fragmentation time period information.

Then, the central storage server may receive second fragmentation storage information sent by one or more second data centers, and may further establish a correspondence between an identifier of the second monitoring device, second fragmentation time period information corresponding to the second fragmentation data, and the second fragmentation storage information, so as to complete a storage process for the second monitoring video data. The monitoring data reading process for the second monitoring device may refer to the above description and is not repeated here.

For example, after the monitoring access server obtains the monitoring video data from the monitoring device executing the recording of the monitoring video data, the monitoring access server may perform data fragmentation processing on the monitoring video data, may divide the monitoring video data into fragment data of different frame types, and may further transmit the fragmented data subjected to fragmentation processing to one or more data centers in a load balancing manner according to the data center list, so as to store the monitoring video data.

The data center can determine a main storage hard disk and spare storage hard disks on two different storage hosts according to the machine room data throughput, the rack data throughput, the host data throughput and the hard disk read-write capacity of the data center aiming at the received fragmented data, and then the data center can write the fragmented data into the main storage hard disk and can write the fragmented data into the spare storage hard disks.

After the data center completes the writing process of the fragment data, the fragment storage information corresponding to the fragment data can be sent to the monitoring access server, then the monitoring access server can forward the fragment storage information to the central storage server, and then the central storage server can store the fragment storage information of the same monitoring device into the monitoring video file corresponding to the monitoring device, so that the storage of the data in the star system area is realized for the monitoring video data, the unlimited expansion of the storage capacity of the monitoring data can be realized, the path number of recording the monitoring video data at the same time is increased, and the hard disk reading and writing speed of the monitoring video data is also increased.
