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.

based on the above characteristics of the video network, one of the core concepts of the embodiments of the present invention is provided, and following the protocol of the video network, even if any one of the communication links between the first video network device and the second video network device fails, the second video network device may further receive the acquisition request through another communication link, and the first video network device may further receive the video network data through another communication link, so that the first video network device can process the video network data.

referring to fig. 5, a block diagram of an embodiment of a data processing system based on the internet of vision according to the present invention is shown, the system includes a first internet of vision device 01 and a second internet of vision device 02, and a plurality of communication links based on the internet of vision are provided between the first internet of vision device 01 and the second internet of vision device 02; the first video network device 01 and the second video network device 02 can mutually transmit video network data through each communication link between the first video network device and the second video network device.

the second video network device 01 comprises a terminal, a server, a base station or a router and the like. The second video networking device 01 also comprises a terminal, a server, a base station or a router and the like.

Referring to fig. 6, a flowchart illustrating steps of an embodiment of a data processing method based on the internet of view according to the present invention is shown, where the method may be applied to the system shown in fig. 5, and the method may specifically include the following steps:

In step S101, a first video network device sends an acquisition request for acquiring video network data to a second video network device through a plurality of communication links, where the acquisition request carries a data identifier of the video network data;

wherein the data identifications of different video network data are different.

In the embodiment of the invention, when the first video network device needs to process the video network data, the video network data can be obtained from the second video network device and then processed.

in order to avoid that the second video network device cannot receive the acquisition request due to the fact that the acquisition request is lost in transmission on one communication link between the first video network device and the second video network device, the first video network device can respectively send the acquisition request to the second video network device through a plurality of communication links.

in step S102, the second video network device receives the obtaining requests through a plurality of communication links respectively;

In step S103, the second video network device obtains video network data according to the data identifier carried in one of the received multiple paths of obtaining requests;

in the embodiment of the present invention, bandwidths of different communication links between a first video networking device and a second video networking device are often different, or numbers of relay devices in different communication links between the first video networking device and the second video networking device are different, so that durations that the same acquisition request needs to be consumed when the same acquisition request is transmitted through different communication links are different, so that the first video networking device sends the same acquisition request to the second video networking device through a plurality of communication links at the same time, but the second video networking device often receives the acquisition request through different communication links at different times.

in this embodiment of the present invention, the purpose of the first video network device obtaining the video network data is to process the video network data, and in order to improve the processing efficiency of the first video network device processing the video network data, in this step, the second video network device may obtain the video network data according to the data identifier carried in the received first obtaining request.

In the embodiment of the present invention, the second internet-of-view device may further receive the acquisition request through another communication link, but does not acquire the internet-of-view data according to the data identifier carried in the acquisition request received through another communication link, and may directly discard the acquisition request received through another communication link.

In step S104, the second video network device sends the video network data to the first video network device through a plurality of communication links, respectively;

in order to avoid that the first video network device cannot receive the video network data due to the fact that the video network data is lost when being transmitted on one communication link between the second video network device and the first video network device, the second video network device can respectively send the video network data to the first video network device through a plurality of communication links.

In step S105, the first video network device receives video network data through a plurality of communication links, respectively;

In step S106, the first video network device processes one of the received multiple video network data.

in the embodiment of the present invention, the video networking data includes a plurality of data packets, and part of the data packets may be lost during the transmission of the video networking data in the communication link, so that the video networking data received by the first video networking device through the communication link is incomplete, and the first video networking device cannot normally process the video networking data.

thus, to enable the first internet-of-view device to process the internet-of-view data normally, the first internet-of-view device may determine the data integrity of each way of received internet-of-view data; the first video network equipment selects complete video network data from the received multi-channel video network data according to the data integrity; the first video network device processes the selected video network data.

in the embodiment of the present invention, each data packet included in the video networking data has a respective number, the numbers of different data packets are different, the video networking data further includes a preset field, and the preset field stores the numbers of all data packets included in the video networking data. Therefore, when determining the data integrity of any received road video network data, the ratio between the number of data packets included in the road video network data and the number of numbers stored in the preset field included in the road video network data can be calculated and taken as the data integrity of the road video network data.
