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 data 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 various data packets are available, and is 32+1024 or 1056 bytes if a single multicast data packet is available, but 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 an embodiment of a video conference control method based on video networking according to the present invention is shown, where the method may be applied to a video networking system, and the method may specifically include the following steps:
step 501: and starting the first conference under the first starting environment through the first server according to the conference starting instruction sent by the video conference management server.
The conference starting instruction is used for instructing the first server to start a first conference with participation of a first participant terminal, and the first participant terminal comprises at least one first video network terminal with a to-be-shown data packet acquisition function and at least one other video network terminal.
In the embodiment of the invention, the video conference is based on a video networking protocol, the video conference opens a first conference through an opening instruction sent by a conference management server, wherein a participant of the first conference, namely a first conference terminal is pulled into the first conference through the video conference management server, when a conference manager sends an opening request of the first conference through a video conference control terminal and inputs a list of first conference terminals participating in the first conference, the video conference control terminal sends the list to the video conference management server through a TCP/IP protocol, so that the video conference management server opens the first conference participated by the first conference terminals.
Illustratively, after the video networking system receives the opening instruction, a first opening environment of a corresponding first conference is prepared through a first server, for example, an autonomous server, which is used for implementing transmission of control instructions in the video networking, for example, receiving a presentation instruction, sending a data acquisition instruction, and the like.

The display instruction is used for indicating that a data packet to be displayed is output to other participant terminals through a first video network terminal, and the first video network data packet is a data packet in a video network format corresponding to the data packet to be displayed.
For example, in a video conference, a speaker may need some files and image information to perform auxiliary explanation, a conference manager may send a request for information output of a exhibition stand through a video conference control terminal, and correspondingly send the exhibition request to a video conference management server, and the video conference management server correspondingly generates an exhibition instruction according to the exhibition request, and is used to send an instruction for outputting the exhibition stand data, that is, exhibition to a first server.

The output signals are divided, the VIDEO display platforms in the current market are generally divided into an analog display platform and a digital display platform, the VIDEO output signals of the analog display platform comprise a composite VIDEO and an S-VIDEO, the definition is generally 400-plus 470 horizontal television lines, and the interlaced scanning mode is adopted; the digital display platform VIDEO output signal is mainly provided with a VGA (VIDEO Graphics Array) output interface except for a composite VIDEO, and is a standard RGB component VIDEO interface which is transmitted to a display image by a computer host, and the digital display platform VIDEO output signal is in a progressive scanning mode, so that the image does not have a flicker phenomenon which is difficult to eliminate by an analog display platform. In addition, other data acquisition devices are also possible, for example, a mobile terminal such as a mobile phone may also acquire a data packet to be displayed, and the present application is not limited thereto.
It should be noted that, when the data format of the data packet to be displayed, which is acquired by the first video network terminal, does not conform to the format of the video network data packet, the data format of the data packet to be displayed needs to be converted, so as to implement receiving and sending of the data packet in the video network.
Step 503: and sending the first video networking data packet to other participant terminals through the second server.
The second server is a server in the video network, and is used for transmitting data in the video network, for example, in a first conference, sending audio data information of a speaker to other participant terminals, or sending a first video network data packet acquired by a video exhibition stand to other participant terminals, and the like.
Step 504: and outputting the data packet to be displayed through the first participant terminal according to the first video networking data packet.
For example, after all other participant terminals receive the first video network data packet, the first video network data packet needs to be decoded and restored to the original format, and then the first video network data packet is displayed to the user through the participant terminals, for example, the first video network data packet is restored to the to-be-displayed data packet in the picture or video format.

For example, after receiving the first video networking data packet, the other conference terminals need to decode the data packet according to the video networking protocol, and then output an original data packet to be displayed, that is, decode the video networking data packet into an original format of the data packet to be displayed, such as a picture or a video format, and then output the data packet to the user, so that all the conference users can see the data packet to be displayed collected by the first video networking terminal at the same time, for example, in a video conference, a presentation used by a speaker, and through synchronous sharing of the presentation, the conference users can understand the content to be presented by the speaker more conveniently.
Referring to fig. 10, a flowchart illustrating steps of an embodiment of a video conference control method based on a video network according to the present invention is shown, where the method may be applied to a video conference management server, and the method may specifically include the following steps:
The video conference starting request is used for starting a first conference with participation of a first participant terminal through a first server in the video network.
For example, referring to fig. 6, when a video conference needs to be started once, a conference manager sends a video conference start request to a video conference management server by operating a video conference management terminal, and the video conference management terminal is provided with a video conference tool, such as pamil, so that management operation of the video conference can be realized.
It should be noted that, unlike the first server and the second server, the video conference management server and the video conference management terminal communicate with each other through an internet protocol, such as a TCP protocol.
That is to say, the video conference management server sends the opening instruction corresponding to the video conference opening request to the first server through the TCP protocol, so as to instruct the first server to establish the conference environment of the corresponding first conference.
And step 1003, pulling the first participant terminal into the first conference according to the video conference starting request.
The display instruction is used for outputting the data packet to be displayed to the first participant terminal through the first video network terminal with the data packet to be displayed acquisition function, and the first video network terminal is any one of the first participant terminals.
The method comprises the steps that the management of a video conference management server on the video conference is achieved through a request issued by a video conference management terminal, according to the video conference starting request, a starting instruction is sent to a first server, and then a participant of the first conference, namely a first participant terminal, is pulled into the first conference, so that the first conference is started. Then, during the first conference, if there is a display requirement for the data packet to be displayed, the conference manager inputs a display request through the video conference management terminal, so that the first server can execute corresponding operations, and the content sharing of the data packet between the participating terminals is realized.
It should be noted that, the first participant terminal of the first conference is not fixed, that is, the conference manager may add the participant dynamically according to actual requirements, for example, when the data content on the second video networking terminal needs to be shared in the conference process, but the second video networking terminal is not the participant of the first conference, and the video conference management terminal may add the second video networking terminal dynamically, so as to implement sharing of the data content.
