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 table 1, the data packet of the access network mainly includes the following parts:
TABLE 1
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 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 table 2, the data packet of the metropolitan area network mainly includes the following parts:
TABLE 2
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.

In the embodiment of the invention, a server program of the scheduling application platform can be deployed on an internet of things server, and a client program of the scheduling application platform can be deployed on a Personal Computer (PC) and can be displayed in a form of a Web site; the Web site is based on Hypertext Markup Language (HTML) and Hypertext Transfer Protocol (HTTP), and can provide an information browsing system of a consistent user interface facing Internet services. Therefore, when a user finds a dangerous event, the user can adopt a video networking terminal or an Ethernet terminal to execute alarm operation, and after the user executes the alarm operation, the terminal can send an alarm message to a server corresponding to the terminal; in order to quickly find out the video terminal equipment around the alarm point, the server (the Ethernet server and/or the video server) can send the alarm message to the scheduling application platform so as to instruct the scheduling application platform to find out the video terminal equipment around the alarm point. The alarm message may include various information such as location information of an alarm point, alarm type information, and the like, and the video network video terminal device is a video network terminal device with a video function such as a set-top box, a video telephone, and the like.
Therefore, the dispatching application platform can receive the alarm message, analyze the alarm message to determine a corresponding alarm point, and then search video network video terminal equipment around the alarm point; the method comprises the following specific steps:
When the dangerous event is processed, the nearby principle is adopted, namely, related personnel in the area around the alarm point are commanded to process the dangerous event, so that the dangerous event can be processed in time, and the loss is reduced; therefore, the embodiment of the invention can take the alarm point as a center, determine a target area in a certain range as the surrounding area of the alarm point, and then search the video terminal equipment of the video network in the target area. Specifically, the device information of all video networking video terminal devices in the video networking system can be acquired, and the device information can include various information, such as position information of the video networking video terminal devices, identification information of the video networking video terminal devices, such as IDs, names of the video networking video terminal devices, and the like; and then screening out the video terminal equipment in the target area from all the video terminal equipment of the video network according to the position information of each video terminal equipment of the video network. After the scheduling application platform determines the video terminal equipment in the target area, a video conference can be established for the video terminal equipment in the target area, namely the conference management platform is informed, and the conference management platform is instructed to establish the video conference for the video terminal equipment in the target area. After video conference is successfully established by the video terminal equipment in the target area, users of the video terminals can carry out video communication, and deployment strategies, real-time condition reports and the like aiming at dangerous events are determined.
To sum up, after receiving an alarm message, a scheduling application platform in the video networking system of the embodiment of the present invention may determine an alarm point corresponding to the alarm message, and determine a target area centered on the alarm point; then video networking video terminal equipment in the target area is searched, and the conference management platform is informed to establish a video conference for the video networking video terminal equipment in the target area; and then realize that the video networking system automatically constructs the video conference for the video networking video terminal equipment around the warning point, need not by manual operation, improved the efficiency of constructing the video conference of video networking after receiving alarm message.

Referring to fig. 6, a flowchart illustrating steps of another data processing method according to an embodiment of the present invention specifically includes the following steps:
step 601, the scheduling application platform receives an alarm message and determines an alarm point corresponding to the alarm message.
In the embodiment of the invention, after the user alarms by adopting the video networking terminal, the video networking terminal sends corresponding alarm information to the video networking server, and in order to quickly establish the video conference of video networking video terminal equipment around the alarm point, the video networking server can send the alarm message to the scheduling application platform so as to instruct the scheduling application platform to establish the video conference for the video networking video terminal equipment. And the dispatching application platform receives the alarm message, analyzes the alarm according to a video networking communication protocol to acquire corresponding information, such as position information, alarm type information and the like of the alarm point, and further determines the alarm point according to the analyzed information. And if the user alarms by adopting the Ethernet terminal, the Ethernet server sends the alarm message to the calling application platform, and the calling application platform analyzes the alarm message by adopting an Ethernet communication protocol.
And step 602, determining a circular area which takes the alarm point as a circle center and takes a set radius as a target area.
After the scheduling application platform determines the alarm point, a target area with the alarm point as the center, namely a surrounding area of the alarm point, can be determined, so that a video conference is established through video terminal equipment of a video network serving as the target area, and processing strategies and actions aiming at dangerous events are deployed in time. Specifically, a set radius can be obtained, and a circular area with the alarm point as the center of a circle and the set radius as the radius is used as a target area; wherein, the set radius can be set according to requirements. Of course, the target area may also be an area in the shape of an area, such as a rectangular area with the alarm point as the center and the set length as the diagonal length, or a triangular area with the alarm point as the center, and the like, and the set length may also be set as required; the embodiments of the present invention are not limited in this regard.
Therefore, the embodiment of the invention can search the video terminal equipment of the video network in the target area to establish the video conference for the video terminal equipment of the video network in the target area, and the specific steps are as follows:
In the embodiment of the invention, when the video network terminal equipment is accessed to the video network server, the corresponding equipment information is reported to the video network server, and the video network server stores the equipment information of each video network terminal equipment; the device information includes a device ID, a device name, and device location information, where the device ID is used to uniquely identify the terminal device of the video networking, and the device ID may also represent the type of the terminal device of the video networking, such as 01 × representing the video terminal device of the video networking, 02 × representing the monitoring terminal device of the video networking, and so on. Therefore, the scheduling application platform can select all video network video terminal devices from a database of the video network server according to the device ID of each video network terminal device, acquire the device information of the video network video terminal devices, and determine the video network video terminal devices in the target area according to the position information in the device information corresponding to each video network video terminal device.
And step 604, calculating the distance between each video network video terminal device and the alarm point according to the position information of each video network video terminal device.
In the embodiment of the invention, the distance between each video network video terminal device and the alarm point can be calculated according to the position information of each video network video terminal device and the position information corresponding to the alarm point; the video networking system comprises a video networking server, a video networking video terminal device, a warning point and a user terminal device, wherein the video networking video terminal device is used for sending position information of the video networking video terminal device to the user terminal device, and the video networking video terminal device is used for sending position information of the video networking video terminal device to the user terminal device. The distance between the video network video terminal equipment and the alarm point can be calculated by referring to the following modes:
one way is that, if longitude of a certain point on the earth is a and latitude is B, spatial coordinates of the point are X ═ cos (B) ((a) Y ═ cos (B) ((a)) z ═ sin (B)), spatial coordinates of the video network terminal device X are X (X1, Y1, z1), spatial coordinates of the alarm point Y are Y (X2, Y2, z2), an included angle therebetween is C ═ acos (X1 × 2+ Y1 × 2+ z1 × z2), C is an angle, and a distance therebetween is C/180 pi R, where R is an average earth radius 6371.
Alternatively, if the 0 degree meridian is taken as a reference, the earth surface distance between any two points on the earth surface can be calculated according to the longitude and latitude of the two points. The Longitude and Latitude of the video terminal equipment X of the video network are (LonA, LatA), the Longitude and Latitude of the alarm point Y are (LonB, LatB), according to the reference of 0-degree Longitude, the east Longitude takes the positive value (Longitude) of the Longitude, the west Longitude takes the negative value (-Longitude), the north Latitude takes the 90-Latitude value (90-Latitude), the south Latitude takes the 90+ Latitude value (90+ Latitude), and then the two processed points are counted as (MLonA, MLataA) and (MLonB, MLatB). Then from the trigonometric derivation, the following formula can be derived for calculating the distance between two points:
C＝sin(MLatA)*sin(MLatB)*cos(MLonA-MLonB)+cos(MLatA)*cos(MLatB)
Distance＝R*Arccos(C)*Pi/180
the Distance is the Distance between the video network video terminal equipment and the alarm point, and R is the radius of the earth.
Of course, the distance between the video terminal device of the video network and the alarm point can be calculated in other manners, which are not listed here.
