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, a rule table of a correspondence relationship between a data segment of a destination address and a video network number of a server is preconfigured according to a protocol of the video network, a video network server matched with a value of the destination address is matched in the preconfigured rule table according to a value corresponding to the destination address of at least one data packet to be sent obtained by terminal equipment through analysis, the terminal equipment sends the at least one data packet to the corresponding video network server for data transfer, so that communication between the video network terminal equipment and an internet terminal is realized, data transmission between a plurality of terminal equipment and a plurality of video network servers can be performed, the working efficiency is improved, and the fault tolerance is increased.
An embodiment of the present invention provides a data packet transmission method, which is used for realizing data communication between a terminal device and the internet by allocating a video networking server to the terminal device.

Specifically, a network of vision NAT server (VNAT) is configured for the network of vision terminal device, one terminal device may communicate with multiple network of vision NAT servers at the same time, or multiple terminal devices use one network of vision NAT server at the same time.
Each video network NAT server has a unique identification code, namely a video network number, and the video network number is a 20-digit string consisting of digits;
a rule table of the corresponding relation between the video network number of the video network NAT server and the data segment of the destination IP value is stored in advance on a video network domain name resolution server (VLAS).
