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.

The internet terminal may be a Computer, a PDA (Personal Digital Assistant), a PC (Personal Computer), etc., and the operating system of the internet terminal may include an operating system such as an IOS and a Windows, which are not limited in the present invention.
The following description is performed from the side of the video network server, and specifically may include the following steps:
the machine code can be a machine code of an internet terminal acquisition video network terminal;
when the video network terminal is produced, a machine Number (SN) is determined for each video network terminal, and is used for uniquely identifying the video network terminal.
In the embodiment of the invention, the machine code can be set into a bar code mode, the bar code is pasted on each video network terminal, a user can scan the bar code on the video network terminal by using a code scanning gun to obtain the machine code of the video network terminal, then the machine code is transmitted to the internet equipment, and the internet equipment transmits the machine code to the video network server.
in the video network, the machine code of the video network terminal has a certain standard, and when the video network server receives the sent machine code, the machine code can be checked based on the standard of the machine code to judge whether the machine code is legal or not.
When the machine code is judged to be illegal, the machine code is discarded, and an error prompt of 'machine code illegal' can be returned to the Internet terminal.
When the machine code is determined to be legitimate, then step 603 may continue.
as an example, the configuration information may include at least any one or more of: MAC address, IP address, authorization code.
The MAC address may be used for the video network terminal to use in the two-layer (data link layer) communication, the IP address may be used for the video network terminal to use in the three-layer (network layer) communication, and the authorization code may be used to authorize the video network terminal.
In the embodiment of the present invention, the video network server may have a preset database, the preset database may store a plurality of configuration information, and the video network server may allocate one configuration information to the machine code from the preset database, as the configuration information corresponding to the machine code.
Specifically, step 603 may include the following sub-steps:

And a substep S13, determining the configuration information of the video network terminal from the plurality of candidate configuration information.

And step 604, controlling the internet terminal, and programming the video network terminal by adopting the configuration information.
Because the video network terminal is not accessed to the video network, after the configuration information of the video network terminal is determined, the video network server can control the internet terminal, and the configuration information is used for programming the video network terminal.
After programming is completed, the terminal of the video network can access the video network based on the configuration information, and specifically, the following terminal network access process can be adopted:
each terminal allowed to access the network must be registered in the node server, and terminals which are not registered cannot access the network. As shown in fig. 7, the process of accessing the network by the terminal involves the following steps:
s21, the node server sends inquiry packets to each port, the terminal sends response packets after receiving the inquiry packets, the response packets contain the registration information of the terminal;
s22, after receiving the response packet sent by the terminal, the node server knows which terminal (set-top box, coding board or memory) is connected to which port, then finds the information of the terminal in the registration information table in the node server, sends the network access command (telling the access network address of the terminal) to the terminal, and the terminal accesses the network after receiving the network access command and sends the network access command response to the node server;
s23, the node server receives the response of network access command from the terminal to know that the terminal has accessed the network, and then sends a state inquiry packet to the port at regular time to check whether the terminal is working normally. And if the terminal works normally, the terminal sends a state query response to the node server after receiving the state query packet. When the node server does not receive the state inquiry response within a period of time, the node server considers that the terminal is moved out of the network, does not send the state inquiry packet any more, and continues to send the inquiry packet to the port.
