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 application: 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.

step 501, a shared platform receives a control request message sent by a control terminal through a core server, wherein the control request message comprises a control instruction for a shooting terminal;
the video networking is a real-time global high-definition video network constructed based on the video networking technology, and can realize the real-time transmission of the full-network high-definition video which cannot be realized by the existing Internet.

In the specific implementation, when the control terminal needs to control the shooting terminals deployed in different local area networks, a control request message can be sent to the video networking core server, the video networking core server converts the control request message based on the internet protocol into the control request message based on the video networking protocol, and sends the control request message to the sharing platform, wherein the control request message includes the identification ID of the IPC device and a control instruction.
Step 502, the sharing platform sends a control request message to the shooting terminal through the coordination server so that the shooting terminal adopts a control instruction to adjust;
in the embodiment of the present application, the control instruction may be a focus control instruction. After receiving the control request message sent by the core server of the video network, the sharing platform can send the control request message to the cooperative conversion server, and the cooperative conversion server sends the control request message to the shooting terminal, so that the shooting terminal adopts a focusing control instruction to perform focusing adjustment.

In an example of the embodiment of the present application, the control terminal initiates a Message request to an Mserver (video networking core server) through a multi-path decoding IE plugin, and a Message body includes a specified IPC device and a focus control code. When the Message request is received by Mserver, a 200Ok is returned to acknowledge receipt of the Message. Mserver initiates an IPC focus control request (FI _ Aperture _ REQ message) to the video network monitoring sharing server. The video network monitoring sharing server transmits an IPC focusing control request (FI _ Aperture _ REQ message) to the protocol forwarding and passing-through. The protocol switch receives the focusing control request, processes the focusing control request, and further the IPC equipment initiates a Message, wherein a Message body carries a focusing control code (FI). The IPC receives the focus control request and sends a 200OK response to the corotation. After executing the focus control code behavior, the IPC sends a Message, and the Message body carries response information. After the protocol receives the Message response Message sent by the IPC, the protocol sends back 200OK to the IPC to confirm the response. The collaboration will send an OK message to the video networking monitor sharing platform to indicate that the focus control request has been processed. And the video networking monitoring sharing platform forwards the OK message to the Mserver. And after receiving the OK Message, the Mserver constructs a Message response Message, and the Message body carries the focusing execution result. And sends the Message to the multipath decoding IE plugin. The Message response Message received by the multipath decoding IE plugin will initiate 200Ok to Mserver to confirm that the Message has been received.
In the embodiment of the application, the control request message sent by the control terminal through the core server is received through the sharing platform, the control request message comprises a control instruction for the shooting terminal, the sharing platform sends the control request message to the shooting terminal through the coordination server so that the shooting terminal adopts the control instruction for adjustment, after the shooting terminal is adjusted, the shooting terminal sends a control response message aiming at the control request message to the cooperative conversion server, the cooperative conversion server sends the control response message to the sharing platform, so that the sharing platform sends the control response message to the control terminal through the core server, therefore, the IPC equipment accessed into the video network can be controlled by the multi-channel decoding IE plug-in configured at the control terminal, and the requirement that part of clients focus and control the IPC equipment accessed into the video network under the Internet environment is met.
