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 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.
Based on the characteristics of the video network, one of the core concepts of the application is provided, the protocol of the video network is followed, and a user can send video network alarm information to a video network platform when giving an alarm, such as video network alarm pictures, video network alarm voice, video network alarm video, video network alarm texts and the like, so that police officers can obtain corresponding word description and scene pictures about the alarm situation when receiving the alarm, and further can quickly identify the category of the alarm situation, the importance and the urgency of the alarm situation and the like, and further the police officers can quickly respond according to the alarm situation.

When the video networking alarm information is compressed, the video networking alarm information is often encoded, and the encoding mode includes base64, MP3, and the like, which is not limited in the embodiment of the present invention.
In step S103, the video networking streaming media server receives the video networking alarm information and forwards the video networking alarm information to the video networking platform;
in the embodiment of the invention, if the video networking streaming media server receives the compressed information obtained by compressing the video networking alarm information, the compressed information can be forwarded to the video networking platform so as to realize the forwarding of the video networking alarm information to the video networking platform.
In step S104, the video network platform receives the video network alarm information, stores the video network alarm information, generates an information identifier of the video network alarm information, and sends the information identifier to a video network streaming media server;
in the embodiment of the invention, the video networking platform receives the compressed information obtained by compressing the video networking alarm information, namely, the video networking platform receives the compressed information forwarded by the video networking streaming media server and then decompresses the compressed information to obtain the video networking alarm information. And then, storing the video network alarm information, for example, storing the video network alarm information on a video network platform, or storing the video network alarm information at a cloud terminal. For later use, an information identifier of the video network alarm information can be generated, the information identifier is used for uniquely identifying the video network alarm information,
in step S105, the video network streaming server receives the information identifier and forwards the information identifier to the video network terminal;
in step S106, the video network terminal receives the information identifier, displays the information identifier, obtains a video network alarm prompt including the information identifier, and sends the video network alarm prompt to the video network streaming media server;
after seeing the information identifier, the user can input an alarm operation on the displayed information identifier, the video network terminal receives the alarm operation, then generates an alarm prompt containing the information identifier, and sends the video network alarm prompt to the video network streaming media server.
In step S107, the video networking streaming server receives the video networking alarm prompt, and forwards the video networking alarm prompt to the video networking platform;
in step S108, the video networking platform receives the video networking alarm prompt, and obtains the stored video networking alarm information according to the information identifier included in the video networking alarm prompt, and plays the video networking alarm information.
